    Full Text Available BACKGROUND Worldwide, breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting for treatment has two common problems in treatment. Achieving local control and prolonging survival by preventing or delaying distant metastasis. Today, treatment of LABC requires a combination of systemic and local/regional therapies. The aim of the study is to study the clinicopathological presentation, age distribution and various modes of management of locally advanced breast carcinoma. Worldwide breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting treatment. MATERIALS AND METHODS The present study includes 50 patients who attended Department of General Surgery for a period of three years. RESULTS The patients were regularly followed up and at the end of the study 35 (70% of the patients were doing well. 4(8% of the patients developed distant metastasis and 3 (6% of the patients developing local recurrence. 8 (16% of the patients were lost follow up. CONCLUSION About half of the cases presenting with breast cancer are in locally advanced stages. Multimodality therapy is the effective treatment of locally advanced carcinoma of breast. Breast cancer management is a challenge and improvement in therapies are needed for disease-free interval and overall survival period.

    Purpose. - Retrospective study of 23 patients treated with conformal radiotherapy for a locally advanced bile duct carcinoma. Patients and methods. - Eight cases were irradiated after a radical resection (RO), because they were N+; seven after microscopically incomplete resection (R1) ; seven were not resected (R2). A dose of 45 of 50 Gy was delivered, followed by a boost up to 60 Gy in R1 and R2 groups. Concomitant chemotherapy was given in 15 cases. Results.-Late toxicity included a stenosis of the duodenum, and one of the biliary anastomosis. Two patients died from cholangitis, the mechanism of which remains unclear. Five patients are in complete remission, six had a local relapse, four developed a peritoneal carcinosis, and six distant metastases. Actuarial survival rate is 75%, 28% and 7% at 1, 3 and 5 years, respectively (median: 16.5 months). Seven patients are still alive with a 4 to 70 months follow-up. Survival is similar in the 3 small subgroups. The poor local control among RON+ cases might be related to the absence of a boost to the 'tumor bed'. In R1 patients, relapses were mainly distant metastases, where'as local and peritoneal recurrences predominated in R2. Conclusion. - Conformal radio-chemotherapy delivering 60 Gy represents a valuable palliative approach in locally advanced biliary carcinoma. (authors)

    This study aims to assess survival, prognostic indicators, and pattern of failure for advanced oropharyngeal cancer treated by induction chemotherapy followed by concomitant chemoradiation (sequential CRT). A retrospective review of 80 consecutive patients who underwent chemoradiation [doublet cisplatin and 5-fluorouracil (PF)] for local advanced oropharyngeal carcinoma at a tertiary center from March 2003 to July 2008 is reported. Seven studies utilizing a similar protocol were reviewed, and all outcomes are collated. At a median follow-up of 32 months, the 3-year overall survival was 75%. Tumor size (p<0.001), age at presentation (p<0.002), and failure to complete the full course of induction chemotherapy (p<0.01) were all found to be significant factors affecting survival. Induction chemotherapy followed by concomitant chemoradiation utilizing doublet PF is an effective treatment for local advanced oropharyngeal carcinoma. At present, the addition of a taxane to the PF regimen cannot be assumed to provide benefit until further evidence emerges from a representative controlled trial. (author)

    The authors analyse a retrospective series of 90 consecutive patients (pts) affected with locally advanced laryngeal carcinoma (T3-4, N0-3 - TNM, UICC 1978) who were radically irradiated from November 1979 to December 1986 at the Radiotherapy Department of the General Hospital of Varese. All the patients were treated with 60 Co and two opposed parallel lateral fields and progressive shrinkage: 66 conventional fractionation (2 Gy once a day, 5 times a week), 24 with an accelerated hyperfractionated regimen (1.5 Gy twice a day, 5 times a week). The median total dose delivered to the tumor and clinically involved nodes was 64 Gy (1678 reu, CRE). Median follow-up was 21 months (range: 3-113). The 5-year overall survival (Kaplan-Meier) was 40.5%. The 5-year disease-free survival, for 47 patients in complete remission at the end of radiotherapy, was 51.9% after irradiation alone and 56.7% with salvage surgery. There were no statistically significant differences in survival according to local spread (T3 vs T4), nodal status (N0 vs N1-3) and dose fractionation regimen (conventional vs accelerated hyper-fractionated). Isoeffect (CRE) values above 1751 reu obtained a 3-year loco-regional control rate was 33.3%. Relevant late sequelae were not observed. Our findings suggest that primary radiotherapy with salvage surgery in reserve could be considered as an effective choice for locally advanced laryngeal carcinoma, at least in selected groups of patients

    We retrospectively analyzed the treatment outcomes of post-operative radiation therapy (PORT) after radical surgery for locally advanced hypopharyngeal carcinoma. From August 2000 to July 2009, 62 patients with hypopharyngeal squamous cell carcinoma were treated with radical surgery followed by PORT in our institute. All patients were followed up for more than 6 months or until any events. All patients underwent a total laryngectomy and neck node dissection prior to PORT. There were 55 male and 7 female patients, with ages ranging from 45 to 82 years (median: 64). Pathologic stage was IVA in 55 and IVB in 7 patients. Irradiation dose ranged from 46 to 70 Gy (median: 60). Twenty-four patients received concurrent chemotherapy. The median follow-up period for surviving patients was 43 months. The 3-year overall and relapse-free survival rates were 56% and 51%, respectively. There was 1 patient with local recurrence and 9 patients with neck node recurrence, and the 3-year loco-regional control rate was 85%. There were 16 patients with distant metastases and the 3-year freedom form distant metastasis rate was 71%. Patients with extra nodal invasion (ENI) had a statistically poorer prognosis (p=0.008). The incidence rate of loco-regional recurrence and distant metastasis were statistically higher in the patients with ENI (p=0.017 and p=0.009, respectively). PORT with concurrent chemotherapy is deemed to be a standard treatment for such high-risk patients. Conformal and precise radiation treatment such as IMRT might also be considered for such high-risk patients in the near future. (author)

    A retrospective review of 72 patients with locally advanced gallbladder carcinoma, between January 1900 and December 1996, was performed. Survival results and prognostic factors are analyzed for the patients treated with a various modalities. The patients were classified by treatment modality: group 1 included to 27 patients treated with palliative surgery alone, and group 2 for 11 patient treated with palliative surgery and radiotherapy; group 3 for 18 patients not treated by any treatment modality, and group 4 for 16 patients treated with radiotherapy alone. Age distribution ranged from 35 to 80 years with a mean of 63 years. The stage was classified by TNM and Nevin's staging system; all patients had an advanced stage more than III. Palliative surgery was done in 3B patients and adjuvant radiation therapy (Rl1 was followed in 11. For 34 patients, in whom no resection was tried, definitive RT was done in 16. Radiation delivered to tumor site and draining nodes up to 45-612 Gy using 10 MY linear accelerator. Chemotherapy was given to 25 patients with 5-FU based regimens. Median survival time was 10.3 months and 3-year survival rates (3-YSR) were 13.0% in all patients. Survival rates according to the treatment modalities were as followed; in palliative surgery alone, 3-YSR was 2.5%; in palliative surgery and adjuvant RT, 3-YSR was 45.5%; in no treatment group, 3YSR were 8.3%; and definitive RT was 13.1%. It was better survival in additional RT after palliative surgery group than palliative surgery alone (p=0.0009). It was better survival in definitive RT group than no treatment group (p=0.022). Significant prognostic factors by multivariate analysis were treatment modalities, the type of tumor and TNM stage. Significant prognostic factors by multivariate analysis were treatment modalities, the type of tumor and the presence of jaundice. It is suggested that RT could be potentially effective as adjuvant treatment modalities after palliative surgery or primary

    Locally advanced cervical carcinoma continues to be a challenge to the clinician due to local failure as well as systemic metastases. Standard intracavitary and external beam techniques result in local control rates of only 35-65%, with long term survival rates of 25-60% in patients with state IIIA-IVA disease, indicating the need to identify new treatment strategies. Optimization programs for remote-afterloading interstitial brachytherapy allow the delivery of higher local doses of radiation to volumes that more closely approximate tumor target volumes as identified on MR scans, leading to improved therapeutic ratios. Identification of subsets of patients more likely to fail standard therapy, either locally or systemically, may be possible through such techniques as in vivo measurements of hypoxia with Eppendorf oxygen electrodes, interstitial fluid pressure measurements, the Comet assay, and nitroimidazole binding methods. Traditional chemotherapies, administered in either a neoadjuvant role or concomitantly with radiation have been disappointing in prospective trials. A variety of new agents are being investigated to determine if they can increase the frequency or duration of complete response. The taxanes, with response rates of 17-23% by themselves, are being assessed as potential radiosensitizers. The camptotheicin CRT-11 (Irinotecan) has demonstrated activity in platinum resistant cervix cancer, with response rates of 24%. Bioradiotherapeutic approaches, using 13-cis-retinoic acid and interferon-2a, are undergoing phase II studies. Neoangiogenesis inhibitors and vaccines against HPV are also being examined. The aggressive pursuit of techniques that help identify those patients most likely to fail, that allow the delivery of higher radiation doses more safely to the target volume, and that incorporate the use of more effective systemic therapies is necessary to improve the outcome for this disease

  8. Locally Advanced Basal Cell Carcinoma with Intraocular Invasion

    Full Text Available We present a 103 - year - old patient, with duration of complaints of about ten years. The initial complaint had been presented as a small nodule, located on the eyebrow, which subsequently ulcerated and encompassed larger regions of the upper and lower eyelids. For the past three years, the patient also had complaints of a worsening of his vision, without seeking for medical help. Within the dermatological examination, an intraocular and periocular localised tumour was established, characterised by a raised peripheral edge and central ulceration. More careful examination revealed that the bulb was fully consumed. The patient refused further diagnosis and treatment. Advanced basal cell carcinomas with intraocular invasion are rare in general. If the patient refuses surgery, radiotherapy and systemic therapy with modern medications such as Vismodegib or Sonidegib are available as treatment options.

    Objective: Since 1979, our institution has treated locally advanced rectal cancer with preoperative irradiation followed by resection with or without intraoperative radiation therapy (IORT). In 1986, our preoperative treatment policy was changed to include bolus 5-FU chemotherapy concurrent with irradiation in hopes of improving resectability, downstaging and/or local control rates. We report the long-term results with the addition of 5-FU chemotherapy to preoperative irradiation. Materials and Methods: From 1979 - 1994, 200 patients with locally advanced rectal carcinoma (primary or recurrent) received preoperative irradiation, resection and IORT if indicated. Bolus 5-FU (500mg/m 2 /day) chemotherapy was administered for three days during weeks one and five of irradiation. The change in treatment policy was limited to the addition of 5-FU chemotherapy: the radiation techniques (four-field), doses (50.4 Gy), and indications for intraoperative radiation (microscopic residual, gross residual, tumor adherence) remained constant. The median follow-up for the entire group of patients was 33 months (.95 months - 199 months), and the minimum follow-up was 1.5 years. Tabular results are 5-year actuarial calculations. Results: One hundred and five patients received preoperative 5-FU chemotherapy and irradiation whereas 95 patients underwent preoperative irradiation alone. Sixty-five percent of the patients were able to undergo complete resections, and 53% had transmural disease upon pathologic examination. The addition of chemotherapy did not affect the rates of resectability or tumor downstaging. However, the 10-year local control rate was significantly improved for those patients who received preoperative chemotherapy: 77% vs. 44% (p<0.01) (see figure). When stratified by extent of resection and stage, those patients who underwent complete resections or had transmural disease had significantly improved local control rates when compared to the non-chemotherapy group: No

    Full Text Available Glycogen-rich clear cell (GRCC is a rare subtype of breast carcinoma characterized by carcinoma cells containing an optically clear cytoplasm and intracytoplasmic glycogen. We present the case of a 55-year-old woman with a palpable mass in the right breast and clinical signs of locally advanced breast cancer (LABC. The diagnosis of GRCC carcinoma was based on certain histopathological characteristics of the tumor and immunohistochemical analysis. To our knowledge, this is the first case of GRCC LABC with intratumoral calcifications. There is no evidence of recurrence or metastatic disease after 14 months’ follow-up.

    Full Text Available Adenoid cystic carcinoma is rare and usually arises in the salivary glands. It grows slowly, but is characterized by easy perineural invasion with local infiltration and distant metastasis. In metastatic setting, the efficacy of intravenous chemotherapy is limited. Herein, we report one male patient who had a advanced, inoperable adenoid cystic carcinoma with lung metastasis, presenting with right buccal unhealed ulcer, pain and poor intake, whose loco-regional tumors responded dramatically after intra-arterial chemotherapy and his symptoms were almost completely relieved. We also make a literature review for treatment of adenoid cystic carcinoma.

    Between 1960 and 1978, 87 patients with locally advanced Tsub(3-4)Nsub(0-3)M 0 carcinoma of the breast were treated with 5,000 to 8,000 rad of external beam supervoltage radiotherapy. Initial clinical eradication of the tumour was observed in 76 of 87 cases (87%), but the actuarial probability of local control at 5 yr was only 53%. Furthermore, the actuarial probability of disease-free survival was 25% at 5 yr and 13% at 10 yr. Most of the patients eventually succumbed to metastatic breast carcinoma and the actuarial survival at 5 yr was 43% and at 10 yr, 16%. The addition of adjuvant low-dose chemotherapy, given to 13 patients, did not affect the rates of local control, survival or disease-free survival. The most common long-term complication was extensive and deforming radiation-induced fibrosis of the treated breast. The actuarial probability of 10-yr survival without a local recurrence and without severe fibrosis of the treated breast was only 17.5%. The role of adjuvant high-dose chemotherapy in the treatment of locally advanced breast carcinoma and the possible use of improved radiotherapy techniques to achieve a more effective long-term local control and a more desirable cosmetic end result are discussed.

    Full Text Available Oncocytic carcinomas of the nasal cavity are extremely rare. We report 1 patient whose primary tumor and neck lymphadenopathies were under control nearly 2 years after combined surgery and radiotherapy. An 80-year-old man with a history of nasal oncocytoma had received excision twice previously. Computed tomography demonstrated locally advanced recurrent tumor invading the paranasal sinuses and orbit with lymphadenopathies in the right neck. Skull base surgery was performed. Pathological examination revealed oncocytic carcinoma. Positron emission tomography showed hypermetabolic lesions in the surgical bed and right neck. The patient subsequently received intensity-modulated radiotherapy to the primary site and the whole neck. Follow-up computed tomography 4 months later showed marked shrinkage of the neck lymphadenopathies. There was no progression after nearly 2 years. Although these tumors have historically been regarded as radioresistant, the combined treatment of surgery followed by radiotherapy may offer the best chance for control of locally advanced disease.

    Full Text Available Introduction: Solid pseudopapillary Carcinoma (SPC is a rare pancreatic Tumor with variable, usually low, malignancy potential. Howewer, several SPC are associated with aggressive behavior, local vascular infiltration, organ invasion, distant metastasis, and can be unresectable. Irreversible Electroporation (IRE is an emerging non-thermal ablation technique for the treatment of locally advanced pancreatic carcinoma. We report the results of four year disease-free follow-up in a case of locally advanced unresectable SPC treated with IRE. Presentation of case: A 24-year female patient with SPC of the pancreas underwent IRE during laparotomy under general anesthesia with intubation. Computed Tomography (CT showed complete tumor thrombosis of splenic vein, encasement of celiac artery and mesenteric vein. Six insertions of 3–4 electrodes per insertion were performed. One month-CT-control showed shrinkage of the tumor. 6 months-post-treatment imaging showed complete regression of the mass, patent Splenic/mesenteric veins, absence of local recurrence or distant metastasis. Post treatment CTs at 12-18-24-30-36-42-48 months follow-up confirmed absence of local or distant recurrence. Discussion: Surgery is the first choice curative treatment of SPC. Howewer aggressive surgery (duodeno-pancreasectomy in unresectable cases, may have a high risk of recurrences, morbidities and death, and bring concerns about endocrine and exocrine insufficiency in a young patient. In these cases, IRE could be a safe and effective alternative treatment and could realize, in selected cases, the condition for a radical surgery, and a bridge to R-0 resection. Conclusions: IRE could represent an effective alternative therapy to surgery in local advanced, unresectable SPC.

    Prognostic factors in the treatment of local advanced hepatocellular carcinoma with radiotherapy, transcatheter arterial embolization and arterial infusion. The treatment effects of radiotherapy and combination modality therapy for the local advanced hepatocellular carcinoma (HCC) were retrospectively reviewed. Three hundred and fifty-six patients of HCC (187 recurrent cases after surgical resection) were treated by: radiotherapy only ; bi-therapeutic method: hepatic artery ligation (HAL) and/or hepatic artery embolization (HAE) plus radiotherapy; and tri-therapeutic method (bi-therapeutic method plus hepatic artery infusion) from 1975 to 1996. Kaplan-Meier method has been used to evaluate the survival rates. There were no significant differences among these three treatment groups in the symptom relied rate, but the mean relief time period was much shorter in radiotherapy alone group (2.5 vs 44 months, P 0.05). There were evident differences in five-year survivals among these three treatment groups: 0 % for radiotherapy alone, 22.8 % for bi-therapeutic method and 38.8 % for tri-therapeutic method (P < 0.01). The prognosis was influenced by Okuda classification. Non-resectable local advanced HCC can be treated by the combination modality therapy, including radiotherapy, with a quite high cure rate. Radiotherapy alone can relief the symptoms. (authors)

    Background and purpose: The majority of patients with pancreatic cancer have advanced disease at the time of diagnosis and are not amenable for surgery. Stereotactic radiotherapy (SRT) may be an alternative treatment for patients with locally advanced disease. The effect of SRT was investigated in the present phase-II trial. Patients and methods: Twenty-two patients with locally advanced and surgically non-resectable, histological proven pancreatic carcinoma were included into the trial. The patients were immobilized by the Elekta stereotactic body frame (SBF) or a custom made body frame. SRT was given on standard LINAC with standard multi-leaf collimator. Central dose was 15 Gyx3 within 5-10 days. Results: Evaluation of response was found to be very difficult due to radiation and tumour related tissue reaction. Only two patients (9%) were found to have a partial response (PR), the remaining had no change (NC) or progression (PD) after treatment. Six patients had local tumour progression, but only one patient had an isolated local failure without simultaneous distant metastasis. Median time to local or distant progression was 4.8 months. Median survival time was 5.7 months and only 5% were alive 1 year after treatment. Acute toxicity reported 14 days after treatment was pronounced. There was a significant deterioration of performance status (P=0.008), more nausea (P=0.001) and more pain (P=0.008) after 14 days compared with base-line. However, 8 of 12 patients (66%) improved in performance status, scored less nausea, pain, or needed less analgesic drugs at 3 months after treatment. Four patients suffered from severe mucositis or ulceration of the stomach or duodenum and one of the patients had a non-fatal ulcer perforation of the stomach. Conclusions: SRT was associated with poor outcome, unacceptable toxicity and questionable palliative effect and cannot be recommended for patients with advanced pancreatic carcinoma

    2013-01-01

    Full Text Available Renal cell carcinoma (RCC is rare but aggressive, with greater than 20% of patients presenting with stage III or IV, disease. Surgical resection of the primary tumor regardless of stage is the treatment of choice, and en bloc resection of involved organs provides the only potential chance for cure. This case report describes a patient with metastatic right-sided RCC with invasion of the inferior vena cava and duodenum managed by en block resection and pancreaticoduodenectomy. This report will review the workup and treatment of locally advanced RCC, as well as the role of cytoreductive nephrectomy in the setting of metastatic disease.

    Purpose. - Retrospective study of 23 patients treated with conformal radiotherapy for a locally advanced bile duct carcinoma. Patients and methods. - Eight cases were irradiated after a radical resection (RO), because they were N+; seven after microscopically incomplete resection (R1) ; seven were not resected (R2). A dose of 45 of 50 Gy was delivered, followed by a boost up to 60 Gy in R1 and R2 groups. Concomitant chemotherapy was given in 15 cases. Results.-Late toxicity included a stenosis of the duodenum, and one of the biliary anastomosis. Two patients died from cholangitis, the mechanism of which remains unclear. Five patients are in complete remission, six had a local relapse, four developed a peritoneal carcinosis, and six distant metastases. Actuarial survival rate is 75%, 28% and 7% at 1, 3 and 5 years, respectively (median: 16.5 months). Seven patients are still alive with a 4 to 70 months follow-up. Survival is similar in the 3 small subgroups. The poor local control among RON+ cases might be related to the absence of a boost to the 'tumor bed'. In R1 patients, relapses were mainly distant metastases, where'as local and peritoneal recurrences predominated in R2. Conclusion. - Conformal radio-chemotherapy delivering 60 Gy represents a valuable palliative approach in locally advanced biliary carcinoma. (authors)

    1983-01-01

    Sixty-five patients with squamous carcinoma of the esophagus (32 patients), carcinoma of the stomach (18 patients) and carcinoma of the biliary tract (15 patients) received from 6000 to 7000 equivalent rad (60-70 Gray equivalents) of helium radiotherapy at 2.0 GyE per fraction, four fractions per day, using multiportal, spread-out Bragg peak therapy. All patients had locally advanced disease without evidence of distant metastases. Partial compensation for tissue inhomogeneities was accomplished. Although palliation of symptoms and regression of tumor was commonly seen, local failure occurred in most patients (77%). The median survival was 8 months. It does not appear that an increase in tumor dose relative to normal tissues can be achieved that would be high enough to increase locoregional control rates over historical control rates with low-LET irradiation. Further studies will be carried out with heavier particles such as neon or silicon in hopes of achieving greater biological effect on these difficult-to-control tumors. 22 references, 6 figures, 1 table

    The objective of this study was to examine a possible association of hemoglobin with clinical outcome in patients with locally advanced squamous cell carcinoma of the cervix who were treated with concurrent chemoradiotherapy (CCRT). Seventy-five patients with Stage IB to IVA disease who were treated with CCRT were reviewed retrospectively. The mean age was 49.8 years. In the treatment, standard radiotherapy was performed accompanied by concomitant chemotherapy using cisplatin. Pre-treatment hemoglobin was defined as the earliest hemoglobin level prior to the initiation of treatment. Weekly nadir hemoglobin levels throughout treatment were averaged and used as average weekly nadir hemoglobin during treatment (AWNHg). The mean follow-up time was 28.6 months. The mean pre-treatment hemoglobin of 11.6 g/dL was significantly reduced to the mean AWNHg of 9.9 g/dL. The levels of pre-treatment hemoglobin and AWNHg were significantly associated with tumor response to treatment. The 5-year cumulative disease-free survival and overall survival rates for all 75 patients were 67.8% and 75.3%, respectively. Multivariate statistical analysis revealed that AWNHg (≥9.0 versus <9.0 g/dL) was an independent prognostic factor for overall survival (p=0.038), but pre-treatment hemoglobin was not a significant factor. AWNHg was one of the most powerful independent predictors of overall survival in patients undergoing CCRT for locally advanced squamous cell carcinoma of the cervix. (author)

    The prognosis of locally advanced lung cancer is reportedly poor in all histologic types. In non-small cell lung cancer, radiation therapy alone results in disappointing long-term survival. Three recent randomized trials, however, have shown a limited but significant improvement of survival with induction chemotherapy, though local control remained poor in these studies as well as in small-cell lung cancer treated with chemotherapy and late radiotherapy. Tow randomized trials focusing on small-cell lung cancer have recently shown significant benefit due to the combination of early concurrent mediastinal irradiation and chemotherapy, with major improvement in local control and a more than 40% 2-year survival rate. The concept of concurrent chemoradiotherapy has also been studied in non-small cell carcinoma with several pilot studies leading to both encouraging results and improved survival rate (up to 40% at 2 years). Ongoing phase III trials are comparing sequential versus concurrent chemoradiotherapy and will define the role of radical surgery after chemoradiotherapy in locally advanced non-small cell lung cancer.

    To retrospectively analyze the patterns of failure and the treatment effects of involved-field irradiation (IFI) on patients treated with locally advanced esophageal squamous cell carcinoma (ESCC) and to determine whether IFI is practicable in these patients. A total of 79 patients with locally advanced ESCC underwent three dimensional conformal (3D)CRT) or intensity modulated radiotherapy (IMRT) using IFI or elective nodal irradiation (ENI) according to the target volume. The patterns of failure were defined as local/regional, in-field, out)of)field regional lymph node (LN) and distant failure. With a median follow)up of 32.0 months, failures were observed in 66 (83.6%) patients. The cumulative incidence of local/regional failure (55.8 vs 52.8%) and in)field regional lymph node failure (25.6 vs 19.4%) showed no statistically significant difference between the IFI and the ENI group (p=0.526 and 0.215, respectively). Out)of)field nodal relapse rate of only 7.0% was seen in the IFI group. Three)year survival rates for the ENI and IFI group were 22.2 and 18.6%, respectively (p=0.240), and 3)year distant metastasis rates were 27.8 and 32.6%, respectively (p=0.180). The lung V10, V20, V30 and mean lung dose of the ENI group were greater than those of the IFI group, while the mean lung dose and V10 had statistically significant difference. The patterns of failure and survival rates in the IFI group were similar as in the ENI group; the regional recurrence and distant metastasis are the main cause of treatment failure. IFI is feasible for locally advanced ESCC. Further investigation is needed to increase local control and decrease distant metastasis in these patients.

Retrospective analysis 106 cases of patients with locally advanced nasopharyngeal carcinoma between November 2005 and March 2007. All patients received cisplatin-based chemotherapy but 15 patients received radiotherapy(RT) alone. Inducing chemotherapy (IC) + RT + adju-vant chemotherapy (AC) regimen in 36 patients, IC+RT regimen was delivered in 25 patients and AC + RT regimen in 30 patients. 61 patients received 1 to 2 cycles of inducing chemotherapy and 66 patients received 3 to 6 cycles of adjuvant chemotherapy after radiotherapy. Chemotherapy started on the first day after the end of the induction chemotherapy, adjuvant chemotherapy begun after radiotherapy for a week. All patients were treated by radiotherapy using 60 Co r-ray, the nasophyarynx primary site was given a total does of 68 -74 Gy. The lymph nodes of the neck was given 60 to 70 Gy. The prophylactic irradiation does of the neck was 48-50 Gy. RESCULT: The median follow up time was 51 months. A total of 58 patients died, the overall survival rate was 45% in whole groups. The 5-year overall survival rates were 33%, 63%, 60% and 50% in RT, IC + RT + AC, IC + RT and RT+AC group, respectively. The 5-year disease-free survival rates were 13%, 56%, 48% and 40% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year relapse-free survival rates were 13%, 53%, 48% and 50% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year metastasis-free survival rates were 6%, 50%, 44% and 47% in RT, IC + RT + AC, IC+ RT and RT + AC group, respectively. There was significant difference in all groups (P 0.05). IC + RT + AC group had heavier acute toxicity effects than other groups, but it did not affect the treatment process, all patients could be tolerated. This retrospective study has demonstrated that alternating Chemo-radiotherapy and early

    To investigate prognostic significance of clinical and pathological stages in patients with locally advanced rectal carcinoma treated with neoadjuvant chemoradiotherapy (neo-CRT) and total mesorectal excision. 210 patients with locally advanced rectal carcinoma (cT3-4 or cN+) treated with neo-CRT followed by total mesorectal excision. Treatment outcomes were compared according to clinical and pathological stage. Overall survival (OS), disease free survival (DFS) among patients with different clinical stage and pathological stage after neo-CRT. The median follow-up time was 47 months (range, 14–98 months). Clinical T stage was associated with 5 year OS (p = 0.042) and 5 year DFS (p = 0.014) while clinical N stage was not associated with 5 year OS (p = 0.440), 5 year DFS (p = 0.711). Pathological T stage was associate with 5 year OS (p = 0.001) and 5 year DFS (p = 0.046); and N stage was associated with 5 year OS (p = 0.001), 5 year DFS (p = 0.002). The pathological stage was further classified into three groups: ypT0–2N0 in 91 patients (43.3 %), ypT3–4N0 in 69 patients (32.9 %) and ypT0–4N+ in 50 patients (23.8 %). While pathological stage (ypT0–2 vs ypT3–4N0 vs ypT0–4N+) was associated with 5 year OS (87.9 %, 75.5 %, 56.7 %, p = 0.000), 5 year DFS (74.5 %, 77.4 %, 50.5 %, p = 0.003). Multivariate analysis showed that ypN stage was an independent prognostic factor for patients 5 year DFS. Pathological stage is strongly associated with treatment outcomes in patients with locally advanced rectal carcinoma treated with neo-CRT followed by total mesorectal excision, which may be used as guidance for further individualized treatment

    Urothelial carcinoma (UC) is the second most common malignancy of the genitourinary system and the sixth most common cancer in the United States. The overall incidence of UC appears to be on the decline, but death rates have remained stable. Stage IV metastatic disease is associated with only a 5% survival rate at 5 years. Gemcitabine and cisplatin combinations or dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin are the preferred regimens for individuals with advance, metastatic disease and a good performance status and organ function. Second-line therapies in this setting are limited. During the course of 1 year, five immune checkpoint inhibitors were approved for treatment of cancers in the locally advanced or metastatic setting: atezolizumab, nivolumab, durvalumab, avelumab, and pembrolizumab. Immunotherapies have played a significant role in the treatment of various cancers and have continued to expand. It is of utmost importance that practitioners include checkpoint inhibitors as treatment options for UC. Based on the limited data, pembrolizumab and atezolizumab may be the drugs of choice, as they are supported by the most influential data to date; however, further research is warranted. Ongoing clinical trials will further assess the benefits of inducing cellular immunity in the treatment of UC. These therapies mark a new landscape in the treatment of UC. In this article, the available data on immune checkpoint inhibitors for the treatment of locally advanced or metastatic UC and their place in therapy are reviewed. © 2017 Pharmacotherapy Publications, Inc.

    Seven patients (five female, two male) had locally advanced epidermoid carcinoma of the anal canal. Three patients had recurrent or persistent disease previously treated and four had advanced primary cancer. Five patients had groin node metastasis. The treatment protocol consisted of chemotherapy with continuous 5-day infusion of 5-fluorouracil, 750 mg/m2, and mitomycin C, 15 mg/m2, by bolus injection and radiation 3000 rads. All patients received one or two cycles of chemotherapy pre-operatively and four (not previously irradiated) received radiation. Tumor regression greater than 50% occurred in five patients, minor regression (25-50%) occurred in one patient and one patient showed no regression (on chemotherapy alone). All patients had total resection of all gross tumor with microscopic clear margins and five had groin dissection. One patient had no residual cancer in specimen and one patient had a microscopic focus only. Four of five patients had residual nodal metastases at groin dissection. Currently three patients are free of disease at 24, 24, and 26 months. Two patients died with disease at 6 months and 34 months, and two patients died of other causes while still free of disease, at 4 and 5 months after resection. Multimodality therapy of locally advanced epidermoid cancer of anal canal can provide effective control and palliation of many of these tumors and, in some, possibly effect cure

    The hedgehog (Hh) signaling pathway has been identified as important to normal embryonic development in living organisms and it is implicated in processes including cell proliferation, differentiation and tissue patterning. Aberrant Hh pathway has been involved in the pathogenesis and chemotherapy resistance of different solid and hematologic malignancies. Basal cell carcinoma (BCC) and medulloblastoma are two well-recognized cancers with mutations in components of the Hh pathway. Vismodegib has recently approved as the first inhibitor of one of the components of the Hh pathway (smoothened). This review attempts to provide current data on the molecular pathways involved in the development of BCC and the therapeutic options available for the treatment of locally advanced and metastatic BCC, and the new targeted therapies in development.

    The protocol and result were described of chemotherapy and radiotherapy for locally advanced esophageal carcinoma, especially for A3 stage one with metastasis at neighboring tissues such as aorta, trachea and bronchia. Chemotherapy was done with 5-FU and CDDP and radiotherapy, with 30 Gy/15 fx/3 wk. Double contrast roentgenography, dynamic CT and MRI were performed to follow the process. The efficacy rate was 55.0% with 4 CR and 7 PR in 20 cases. Three CR patients survived at present. Major adverse effects were leukopenia and thrombocytopenia, of which grade 4 were found in 14 and 12% cases, respectively. Low-dose FP therapy might be useful for lowering the adverse effects and for elevating the efficacy rates. (K.H.)

    Development of esophageal squamous cell carcinoma (ESCC) involves alterations in multiple genes with corresponding proteins. Recent studies have demonstrated that centrosomal protein 55 (CEP55) shares certain features with oncogenes, and CEP55 overexpression is associated with the development and progression of malignant tumors. The present study aimed to analyze, for the first time, whether CEP55 expression is related to clinicopothalogic features in the esophageal squamous cell carcinoma (ESCC), as well as patient survival. A total of 110 patients with mid-thoracic ESCC who suffered from Ivor-Lewis were enrolled. The CEP55 expression profile of these patients in tumour tissues and corresponding healthy esophageal mucosa (CHEM) was detected by immunohistochemistry and semi-quantitative reverse transcription-polymerase chain reaction analyses. Correlations between CEP55 expression and clinicopathological factors were analyzed using χ 2 test. The log-rank test was employed to calculate survival rate. A Cox regression multivariate analysis was performed to determine independent prognostic factors. The results demonstrated that CEP55 expression in ESCC was significantly higher than that of CHEM (POverexpression of CEP55 was significantly associated with differentiation degree (P=0.022), T stage (P=0.019), lymph node metastasis (P=0.033), clinicopathological staging (P=0.002) and tumor recurrence (P=0.021) in locally advanced ESCC patients. In addition, CEP55 overexpression was significantly associated with reduced overall survival of patients after surgery (P=0.012). The 5-year survival rate of patients without CEP55 overexpression was significantly higher than that of patients with CEP55 overexpression (P=0.012). Therefore, these findings suggest that CEP55 overexpression correlates with poor prognosis in locally advanced ESCC patients.

    Purpose: To evaluate the efficacy and toxicity of weekly paclitaxel with concurrent radiotherapy followed by adjuvant chemotherapy (AC) in patients with locally advanced nasopharyngeal carcinoma (NPC). Methods and materials: Between 2004 and 2007, 54 patients with locally advanced NPC were included in this protocol. Patient characteristics: median age 48; 69% male; 52% World Health Organization (WHO) III; 50% stage III, 50% stage IV. The patients underwent a course of definitive conventional radiotherapy (70 Gy in 7 weeks with 2 Gy/fraction), with concurrent weekly paclitaxel 35 mg/m 2 from the first to the sixth week of radiation. AC was started 4 weeks after the end of the radiotherapy (RT), paclitaxel 135 mg/m 2 on day 1 and cisplatin 30 mg/m 2 on days 1-3 were administered every 4 weeks for two cycles. Results: Median follow-up was 32 months. Eighty-five percentage of complete response and 15% partial response were achieved at the time of one month after AC. The 3-year actuarial rate of local regional control was 86%; distant metastases-free survival, progression-free survival and overall survival at 3 years were 81%, 69% and 76%, respectively. Forty-nine (91%) patients completed six courses of concurrent chemotherapy with weekly paclitaxel, and 4 (7%) patients delayed at the second cycle of AC. No patient developed severe acute toxicities. Conclusions: Weekly paclitaxel with concurrent RT followed by AC is a potentially effective and toxicity tolerable method for locally advanced NPC. Further studies are needed to identify the optimal dose of weekly paclitaxel in this strategy.

    Purpose : To evaluate the effects of postoperative radiotherapy and chemotherapy on the pattern of failure and survival for locally advanced rectal carcinoma, we analyzed the two groups of patients who received curative resection only and who received postoperative radiochemotherapy retrospectively. Materials and Methods : From June 1989 to December 1992, ninety nine patients with rectal cancer were treated by curative resection and staged as B2-3 or C. Group I(25) patients received curative resection only and group II(74) patients postoperative adjuvant therapy. Postoperative adjuvant group received radiation therapy (4500 cGy/ 25fx to whole pelvis)with 5-FU (500 mg/m 2 , day 1-3 IV infusion) as radiosensitizer and maintenance chemotherapy with 5-FU(400mg/m 2 for 5 days) and leucovorin (20mg/m 2 for 5 days) for 6 cycles. Results : The patients in group I and group II were comparable in terms of age, sex, performance status, but in group II 74% of patients showed stage C compared with 56% of group I. All patients were flowed from 6 to 60 months with a median follow up of 29 months. Three year overall survival rates and disease free survival rates were 68%, 64% respectively in group I and 64%, 61%, respectively in group II. There was no statistical difference between the two treatment groups in overall survival rate and disease free survival rate. Local recurrences occurred in 28% of group I, 21% of group II (p>.05) and distant metastases occurred in 20% of group I, 27% of group II(p>.05). The prognostic value of several variables other that treatment modality was assessed. In multivariate analysis for prognostic factors stage and histologic grade showed statistically significant effect on local recurrences, and lymphatic or vessel invasion on distant metastasis. Conclusion : This retrospective study showed no statistical difference between two groups on the pattern of failure and survival. But considering that group II had more advanced stage and poor prognostic

    Multi-modality treatment consisting of cisplatin, VP-16, and 5-fluorouracil chemotherapy given concomitantly with external beam radiation was used to treat 64 patients with locally advanced Stage III non-small cell lung carcinoma. This regimen was used in a preoperative fashion for four cycles in patients considered surgically resectable and with curative intent for six cycles in the remainder of patients. The clinical response rate for the entire group was 84% and the overall local control rate was 74%. The median survival was 13 months with a median follow-up for live patients of 19 months. The actuarial 3-year survival and disease-free survival rates were 30% and 23%, respectively. Histologic complete response was 39% and appeared to predict for survival. The 3-year actuarial survival and disease-free survival rates for 23 resected patients were 69% and 45%, respectively, with the complete histologic responders having a disease-free survival of 78%. The pattern of first recurrence did not appear to differ by histology or presence of lymph nodes in this subset of patients. The actuarial 3-year survival and disease-free survival rates for inoperable patients receiving six cycles of treatment were 18% and 23%, respectively. The local control was 67% with the majority of these patients having Stage IIIB disease. The Mountain International staging system appeared to predict for operability, local recurrence, and survival. This concomitant treatment regimen is feasible, with the major toxicities being leukopenia, nausea, and vomiting

    Full Text Available To evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with T3 or T4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or Docetaxel, Cisplatin, and 5-FU (TPF induction chemotherapy followed by surgery. All patients were planned to receive chemoradiotherapy after surgery. The primary end-points were organ preservation and progression-free-survival. SPSS version 17 was used for data analysis. Median follow-up was 16 months. The median age of the patients was 62 years old (23-75 years. Man/woman ratio was 1.13. The primary site of the tumor was the tongue in most patients (48%. No significant difference was observed between pathologic characteristics of the two groups. Chemotherapy group showed 16% complete pathologic response to TPF. No significant difference in organ preservation surgery or overall survival was detected. However, the patients in the chemotherapy group had longer progression-free-survival (P=0.014. Surgery followed by chemoradiotherapy with or without TPF induction results in similar survival time. However, progression-free-survival improves with the TPF induction chemotherapy. Studies with more patents and new strategies are recommended to evaluate organ preservation improvement and long-term outcomes.

    Various techniques are available for radiotherapy of hepatocellular carcinoma, including three-dimensional conformal radiotherapy, linac-based intensity-modulated radiotherapy and helical tomotherapy. The purpose of this study was to determine the optimal radiotherapy technique for hepatocellular carcinoma. Between 2006 and 2007, 12 patients underwent helical tomotherapy for locally advanced hepatocellular carcinoma. Helical tomotherapy computerized radiotherapy planning was compared with the best computerized radiotherapy planning for three-dimensional conformal radiotherapy and linac-based intensity-modulated radiotherapy for the delivery of 60 Gy in 30 fractions. Tumor coverage was assessed by conformity index, radical dose homogeneity index and moderated dose homogeneity index. Computerized radiotherapy planning was also compared according to the tumor location. Tumor coverage was shown to be significantly superior with helical tomotherapy as assessed by conformity index and moderated dose homogeneity index (P=0.002 and 0.03, respectively). Helical tomotherapy showed significantly lower irradiated liver volume at 40, 50 and 60 Gy (V40, V50 and V60, P=0.04, 0.03 and 0.01, respectively). On the contrary, the dose-volume of three-dimensional conformal radiotherapy at V20 was significantly smaller than those of linac-based intensity-modulated radiotherapy and helical tomotherapy in the remaining liver (P=0.03). Linac-based intensity-modulated radiotherapy showed better sparing of the stomach compared with helical tomotherapy in the case of separated lesions in both lobes (12.3 vs. 24.6 Gy). Helical tomotherapy showed the high dose-volume exposure to the left kidney due to helical delivery in the right lobe lesion. Helical tomotherapy achieved the best tumor coverage of the remaining normal liver. However, helical tomotherapy showed much exposure to the remaining liver at the lower dose region and left kidney.

    Purpose: To examine the efficacy of fast neutron radiotherapy for the treatment of locally advanced and/or recurrent adenoid cystic carcinoma of the head and neck and to identify prognostic variables associated with local-regional control and survival. Methods and Materials: One hundred fifty-nine patients with nonmetastatic, previously unirradiated, locally advanced, and/or recurrent adenoid cystic carcinoma (ACC) of the head and neck region were treated with fast neutron radiotherapy during the years 1985-1997. One hundred fifty-one patients had either unresectable disease, or gross residual disease (GRD) after an attempted surgical extirpation. Eight patients had microscopic residual disease and were analyzed separately. Sixty-two percent of patients had tumors arising in minor salivary glands, 29% in major salivary glands, and 9% in other sites such as the lacrimal glands, tracheal-bronchial tree, etc. Fifty-five percent of patients were treated for postsurgical recurrent disease and 13% of patients had lymph node involvement at the time of treatment. The median duration of follow-up was 32 months (range 3-142 months). Actuarial curves for survival, cause-specific survival, local-regional control, and the development of distant metastases are presented for times out to 11 years. Results: The 5-year actuarial local-regional tumor control rate for the 151 patients with GRD was 57%; the 5-year actuarial overall survival rate was 72%; and the 5-year actuarial cause-specific survival rate was 77%. Variables associated with decreased local-regional control in the patients with GRD as determined by multivariate analysis included base of skull involvement (p < 0.01) and biopsy only versus an attempted surgical resection prior to treatment (p = 0.03). Patients without these negative factors had an actuarial local-regional control rate of 80% at 5 years. Patients with microscopic residual disease (n = 8) had a 5-year actuarial local-regional control rate of 100%. Base of

    The aim of the study was to conduct a retrospective analysis of advanced laryngeal cancer patients treated with postoperative radiotherapy in order to assess the clinical outcome and identify prognostic factors which may alter their prognosis. We retrospectively reviewed the medical records of 165 patients with advanced laryngeal carcinoma treated with postoperative radiotherapy between 1984 and 1996. Initially all patients underwent total laryngectomy combined, in 91 cases, with unilateral or bilateral neck dissection. Postoperative irradiation was initiated within 15 to 162 days after surgery (mean - 53 days). The total dose varied between 50-70 Gy with the fraction size of 2.0 Gy. The analysis of overall survival and local control was performed using the actuarial method according to Kaplan and Meier. Sex, age, performance status, T, N stages, primary tumor site, hemoglobin level, histological grade, involvement of lymph nodes, extracapsular lymph node extension, surgical margin status, presence of extension of the primary beyond larynx and/or thyroid cartilage invasion and/or subglottic extension and time from operation to start of radiotherapy were studied in multivariate analysis for the prognostic significance for both overall survival and local control. The actuarial survival for the entire group of postoperatively irradiated patients was 0.70, 0.56 and 0.43 at two, five and ten years respectively. The actuarial local control for the entire group of patients was 0.86, 0.78 and 0.75 at one, two and three years respectively and remained stable thereafter. For the overall survival - sex, positive lymph nodes and time interval between surgery and radiotherapy were found to be the significant prognostic factors. For the local control the extracapsular lymph node extension was found to be the only significant prognostic factor. Combined surgery and postoperative radiotherapy is an effective treatment modality in the management of locally advanced laryngeal cancer

    To describe the tolerability of two chemotherapy regimens, gemcitabine and cisplatin (GC) and methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) for adjuvant treatment of patients with locally advanced urothelial cancer after radical cystectomy. The USC Department of Urology bladder cancer database was searched for subjects who received adjuvant chemotherapy following cystectomy for transitional cell carcinoma with extravesical and/or lymph node involvement, yielding 187 cases. Clinical details regarding toxicity, number of cycles administered, and cancer outcome were analyzed. The majority of subjects had lymph node involvement (70%). Sixty-eight percent of subjects received MVAC and 32% received GC, the latter regimen was predominant after 2000. Fifty-six percent of subjects received all four planned cycles (51% GC and 58% MVAC). With a median follow-up of 11.2 years (range 1.9-19.6), 96 patients (51%) have suffered a relapse, with no significant difference between chemotherapy regimens. Median time to recurrence for the population was 3.7 years and median overall survival is 4.6 years (3.0-9.3). The median time from recurrence to death was 6.7 months and was not significantly different between MVAC and GC. Both MVAC and GC are tolerated after cystectomy for advanced urothelial carcinoma. A significant proportion of high-risk patients survive, free of disease, beyond 10 years. At recurrence, patients previously treated with adjuvant chemotherapy have a survival that appears much shorter than patients who develop metastases in the absence of this exposure, suggesting resistance to salvage chemotherapy.

    Laryngeal cancer is the commonest carcinoma of the head and neck region with Squamous-cell carcinomas (SCC) in 90 % of cases (Birchall Met al 2008) The incidence of laryngeal cancer was relatively about 160,000 new cases per year. The disease predominantly affects men; about 2.4% of all cancer cases and 2.1% of all cancer deaths worldwide ,also in United States in 2012 the Es)mated new cases is 12,360 and deaths from laryngeal cancer is 3,650. The majority of patients with SCC of larynx present with locally advanced (LA) disease.(American Cancer Society, 2012) The incidence of laryngeal cancer in the Kasr El-Aini Center of Radiation Oncology and Nuclear Medicine (NEMROCK), Faculty of Medicine, Cairo University from year 2005 - 2008 is 3.1%per year. Advanced laryngeal cancer is generally considered as the disease in stages III and IV based on the primary tumor extension and/or the presence of metastatic lymph node(s) in the neck and it accounts for roughly 40% to 50% of patients with laryngeal cancer (Chen AY, et al 2006). From the second half of the 20th century total laryngectomy combined with a neck dissection was considered a treatment of choice for advanced laryngeal cancer (Genden EM et al, 2007). In most institutions, postoperative radiotherapy as adjuvant treatment following ablative surgery with radiation doses up to 60-66 Gy has also become the standard approach for patients with stage III-IV laryngeal cancer (Corvo R , 2007). However, the treatment of advanced laryngeal cancer seams to be a permanent challenge, but the management of patients with advanced laryngeal cancer has become more complex as other modalities including induction chemotherapy followed by radiotherapy or concurrent chemo-radiotherapy have evolved with the goal of preserving the larynx and reserved total laryngectomy as a salvage procedure for cases with less than 50% response to induction chemotherapy or in those who have persistent disease following concurrent chemo

    Purpose: A growing body of evidence supports the efficacy of accelerated superfractionated radiotherapy with concomitant boost for advanced head-and-neck carcinomas. This study represents a single-institution experience, performed to identify the factors influencing tumor control, survival, and toxicity. Methods and Materials: Between 1988 and 1999, 133 patients with primary squamous cell head-and-neck carcinoma underwent accelerated superfractionated radiotherapy using a concomitant boost. The concomitant boost in this regimen was delivered using reduced fields delivered 3 times weekly in a twice-daily schedule during the final phase. The total radiation dose ranged from 64.8 Gy to 76.5 Gy (mean 71.1). Patients were evaluated in follow-up for local control and late toxicity. Multivariate analysis of treatment and patient parameters was performed to evaluate their influence on toxicity, local control, and overall survival. Results: With a mean follow-up of 37 months, the actuarial overall survival rate for the entire group at 5 years was 24% and the local control rate was 57%. The tumor volume was the most significant predictor of local control, such that each 1-cm 3 increase in volume was associated with a 1% decrease in local control. For patients with tumor volumes ≤30 cm 3 vs. >30 cm 3 , the 5-year disease-specific survival rate was 52% and 27% (p = 0.004) and locoregional control rate was 76% and 26% (p<0.001), respectively. Seventy-six patients with a minimum of 12 months and median of 39 months toxicity follow-up were studied for late effects. None of these patients experienced Grade 4 or 5 toxicity. The actuarial rate of significant toxicity (Grade III or greater) was 32% at 5 years. Of the toxicities observed, xerostomia (19%) was the most common. Multivariate analysis revealed N stage and dose as independent predictors of Grade 3 effects. Conclusion: The locoregional control and survival for patients in this institutional experience compare favorably to

    Purpose: To evaluate the efficacy and outcomes of neoadjuvant cisplatinum and epirubicin chemotherapy followed by concurrent cisplatinum chemotherapy with radiotherapy in patients with locally advanced nasopharyngeal carcinoma. Methods and Materials: One hundred ten patients (80 male, 30 female) with locally advanced nasopharyngeal carcinoma, staged according to the 1997 International Union Against Cancer/American Joint Committee on Cancer classification system as IIB (n = 9), III (n = 20), IVA (n = 32), and IVB (n = 49), World Health Organization types II (n = 25) and III (n = 85), were included in this protocol between January 1998 and July 2000 at King Faisal Specialist Hospital and Research Centre. Patients underwent two cycles of induction chemotherapy with cisplatinum 100 mg/m 2 and epirubicin 70 mg/m 2 on Days 1 and 21, followed by a radical course of radiotherapy (6,600 cGy in 6.5 weeks, 200 cGy/fraction) starting on Day 42, with three cycles of concurrent cisplatinum 25 mg/m 2 for 4 days on Days 42, 63, and 84. Results: Of 110 patients included in this study, intracranial extension was present in 32 (29%), and nodal stage was N3 in 49 (45%). Complete remission and partial remission were achieved in 87 patients (79%) and 23 patients (21%), respectively. At a median follow-up for surviving patients of 37 months (22-55 months), 49 of 110 patients (44%) had failed treatment: 12 with local, 9 with regional nodes, 4 locoregional, 5 locoregional plus distant areas, and 19 with distant metastases. At the time of writing, 34 patients had died; all deaths were related to the patients' cancer except for 1 patient with treatment-related toxicity. Three-year actuarial overall survival, relapse-free survival, locoregional control, and distant metastasis-free survival rates were 89%, 78%, 88%, and 89% for patients with stage IIB; 71%, 70%, 89%, and 74% for stage III; 68%, 49%, 61%, and 77% for stage IVA; and 70%, 45%, 60%, and 69% for stage IVB, respectively.

    The purpose of this study was to retrospectively investigate the efficacy of multidisciplinary therapy (concomitant radiotherapy and intra-arterial infusion of 5-fluorouracil (5-FU) followed by maxillectomy) in the treatment of squamous cell carcinoma of the maxillary sinus. We reviewed 71 patient records with locally advanced but respectable carcinoma of the maxillary sinus treated by means of multidisciplinary therapy between 1978 through 1997. The clinical T factor for these patients, according to the UICC definitions (1997), was 12 for T2, 46 for T3, and 13 for T4. Twelve patients were diagnosed as node-positive at initial presentation. Intra-arterial 5-FU was delivered via a superficial temporal artery in accordance with radiotherapy, and the cumulative 5-FU dose ranged from 2,900 mg to 5,250 mg (median 5,000 mg). The total radiotherapy dose ranged from 29 Gy to 48 Gy (median 48 Gy) with conventional fractionation. Patients underwent radical maxillectomy thereafter. The 5-year overall survival rate and disease-specific survival rate of all the patients were 58% and 68%, respectively. There was no significant correlation of clinical T factor or N factor with disease-specific survival on univariate and multivariate analysis. The overall treatment-related mortality rate was 3.7%. Radiation cataract later developed in all evaluable patients whose lenses were within the treatment volume. About a half of the operable T4 patients survived over 5 years by means of the above-mentioned multidisciplinary therapy. This multidisciplinary therapy should be compared to treatment with a combination of surgery and postoperative chemoradiotherapy. (author)

    Neoadjuvant chemotherapy followed by surgery is a promising approach in locally advanced cervical carcinoma. The aim of this study was to evaluate the feasibility, technical aspects, and clinical results of surgery after induction chemotherapy in this patient population. Forty-one untreated cervical carcinoma patients staged as IB2 to IIIB received three 21-day courses of cisplatin 100mg/m2 on day 1 and gemcitabine 1000 mg/m2 on days 1 and 8 followed by surgery or concomitant chemoradiation. The response to chemotherapy, operability, surgical/pathological findings, disease-free period, and survival of the surgically treated patients were evaluated. All 41 patients were evaluated for toxicity and 40 were evaluated for response. The overall objective response rate was 95% (95% confidence interval 88%-100%), and was complete in three patients (7.5%) and partial in 35 (87.5%). Granulocytopenia grades 3/4 occurred in 13.8% and 3.4% of the courses, respectively, whereas nonhematological toxicity was mild. Twenty-three patients underwent type III radical hysterectomy. Mean duration of surgery was 3.8 h (range 2:30-5:20), median estimated blood loss was 670 ml and median hospital stay was 5.2 days. Intraoperative complications occurred in one case (venous injury). In all but one case the resection margins were negative. Four patients (17%) had positive nodes (one node each); six (26%) had complete pathologic response, three (13%) had microscopic; and 14 (60%) macroscopic residual disease. At 24 months of maximum follow-up (median 20), the disease-free and overall survival rates were 59% and 91%, respectively. Induction chemotherapy with cisplatin/gemcitabine produced a high response rate and did not increase the difficulty of surgery. Operating time, blood loss, intraoperative complications, and hospital stay were all within the range observed for type III hysterectomy in early stage patients. We therefore conclude that type III radical hysterectomy is feasible in locally

    The study aimed to evaluate the long-term outcome in patients with advanced local recurrent nasopharyngeal carcinoma (NPC) treated with or without reirradiation. A total of 44 patients treated without reirradiation (non-RT + chemotherapy) were matched with 44 patients treated with reirradiation (re-RT+/-chemtherapy) by age, sex, Karnosky performance score (KPS), rT stage, rN stage, and time interval between initial radiation and recurrence (TI). Overall survival (OS) rate and time to progression (TTP) rate were assessed using Kaplan–Meier method, log-rank test, and Cox regression analysis. From March 2008 to December 2013, a total of 88 well-balanced rT3–4 N0-1 NPC patients were retrospectively analyzed. After a median follow-up of 27 months (range: 6–85), the 5-year OS rate and TTP rate was 23.4 %, 39.0 % in the non-RT + chemotherapy group and 27.5 %, 49.8 % in the re-RT+/-chemtherapy group, respectively. Multivariate analysis showed that significant toxic effect was the only significant prognosticator correlated with OS (HR: 2.15, 95 % CI = 1.02–4.53, p = 0.044). No statistically significant survival differences were observed between the two treatment groups in either univariate or multivariate analyses. Compared with reiradiation, treating advanced local recurrent NPC with chemotherapy alone warrants further validation in the view of its similar survival and more acceptable toxicities.

    Purpose: Radiation therapy is the standard management for locally advanced cervical cancer, but it has not yielded fully satisfactory results; a relatively high incidence of local failure remains. Standard radiation therapy techniques combine external beam radiation and brachytherapy generating a homogeneously composite dose distribution covering the lateral parametria but may not be adequate in the uterosacral and perirectal areas due to the spatial arrangement of intracavitary system and the constraints of rectal tolerance. We hypothesize that these dosimetric characteristics might lead to a higher incidence of central/marginal failures when the uterosacral space is involved by locally advanced carcinoma of uterine cervix. Methods and Materials: Between January 1970 and December 1989, 343 patients with clinical Stage IIIB cervical cancer were treated at the Mallinckrodt Institute of Radiology with radiation therapy alone. We identified 83 patients with clinical evidence of tumor in the uterosacral region; the remaining 260 patients either did not have uterosacral involvement or were unspecified. The dose of external beam irradiation ranged from 18.02 to 33.20 Gy to the central pelvis and 48.22 to 59.40 Gy to the lateral parametrium. The average total dose, including brachytherapy contribution, to point A and the lateral pelvis was 80.30 to 86.46 Gy and 60.50 to 73.40 Gy, respectively. External beam dose to the lateral parametria was, on average, 10 Gy higher in patients with uterosacral involvement. Results: We categorized the patterns of pelvic failure into central/marginal (including medial parametrium) and lateral parametria. The cumulative incidence of central/marginal failure at 5 years was significantly higher in the group of patients with uterosacral involvement (36% compared with 21% for patients without uterosacral involvement or unspecified) (p = 0.002). Lateral parametrial failure was similar for patients with and without uterosacral involvement (39

    The aim of this study was to evaluate the efficacy and toxicity of concurrent chemoradiotherapy (CRT) with gemcitabine plus regional hyperthermia (HT) for locally advanced pancreatic carcinoma (LAPC). A total of 29 patients with LAPC treated with concurrent CRT using gemcitabine were retrospectively analyzed. Radiotherapy was administered with a median total dose of 61.2 Gy. Of the 29 patients, 20 (69%) also underwent regional HT during CRT (CRHT group). The remaining 9 patients did not receive regional HT (CRT group) because of a common bile duct stent placement, patient refusal, older age, or obesity. The efficacy and toxicity of the treatments and the predictors of good outcome were evaluated. The median disease progression-free and overall survival times were significantly better for the CRHT group than for the CRT group (8.8 vs. 4.9 months, P=0.02, and 18.6 vs. 9.6 months, P=0.01), respectively. Grade 3-4 hematological toxicities for the CRHT group were detected in eight patients (40%) and grade 3 nonhematologic toxicity in one (diarrhea). Concurrent CRT using gemcitabine with regional HT may be a feasible and promising regimen for LAPC, and the results justified further evaluation in a large number of patients to confirm its definite benefit.

    Purpose: To perform a retrospective review of stage III-IV squamous cell carcinoma of the tonsil managed by definitive concurrent chemoradiotherapy (CCRT) in order to analyze the patients’ outcome and to evaluate the acute and late toxic effects of this treatment modality. Material and methods: Between January 2005 and December 2010, 36 patients with locally and/or regionally advanced tonsillar cancer underwent three dimensional conformal radiotherapy (3DCRT) with concurrent platinum-based chemotherapy. The dose prescription of the planning target volume for gross tumor and low-risk subclinical disease was 70 Gy and 50 Gy, respectively. Conventional fractionation with a daily dose of 2.0 Gy, 5 times per week was used. Concurrent chemotherapy consisted of cisplatin 30 mg/m2 given on a weekly basis. Acute and late radiotherapy-related toxicities were recorded using European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group (EORTC/RTOG) grading system. The 3-year locoregional relapse-free survival (LRRFS), disease-free survival (DFS), and overall survival (OS) rates were calculated using the Kaplan-Meier method. Results: The median follow-up of all patients was 20.5 months (range, 5 to 90 months). The median followup of living patients was 59 months (range, 30 to 90 months). Complete response rates of the primary tumor and of the nodal disease were 72.2% and 64.0%, respectively. A complete composite response was present in 25 patients (69.4%). Treatment failure occurred in 15 out of 25 patients who achieved complete composite response following CCRT. The 3-year LRRFS, DFS, and OS rate was 38.8%, 27.8%, and 27.3%, respectively. Grade 3 mucositis occurred in 58.3% of patients. Xerostomia grade 2 was revealed in 72.2% of patients. Conclusion: Taking into account the low 3-year survival rates observed in our study and the high percentage of grade 2 xerostomia, it can be concluded that in the future, instead of 3DCRT with concurrent

    Objective: To investigate the delineation of gross tumor volume (GTV) in locally advanced nasopharyngeal carcinoma (LANC) according to imageological changes before and after induction chemotherapy (IC) in order to decrease high dose area and protect normal tissue better. Methods: Between Mar 2010 to Jan 2011, 11 patients with LANC were enrolled and treated with TPF regimen followed by intensity-modulated radiotherapy (IMRT) with concurrent chemotherapy, target volumes were delineated based on fused CT imaging before and after IC following project determination. Tumor target volumes after and before IC were respectively delineated according to imaging tumor residues and were overlaid by CTV nx in order to ensure radical doses for the imaging tumor volume before IC, the resulting differences of tumor target volumes of IC before and after were measured and analyzed by paired t-test. Results: Before and after IC, the average volumes of GTV nx were respectively 44.72 cm 3 and 28.87 (t=3.89, P=0.003), the average volumes of GTV nd were respectively 32.76 cm 3 and 19.82 cm 3 (t=2.47, P=0.033), the volumes of maximum dose area in brainstem and spinal cord as well as eyeball decreased (t=2.93-4.59, all P<0.05). Conclusions: LANC treated by 3 cycle TPF regimen followed by IMRT with concurrent chemotherapy shows significant shrinkage of tumor volume. The volume of high dose region which caused by normally recovered tissues were decreased by re-delineation of target volume in brainstem and spinal cord as well as eyeball of CT images after IC.

    The purpose of this study was to evaluate the prognostic impact of endoscopic traversability in patients with locally advanced esophageal squamous cell carcinoma.This retrospective study was based on medical records from a single tertiary medical center. The records of 317 patients with esophageal squamous cell carcinoma treated with surgery or definitive chemoradiotherapy (CRT) between January 2009 and March 2016 were reviewed. Finally, we retrieved the data on 168 consecutive patients. These 168 patients were divided into 2 groups based on their endoscopic traversability findings: Group A (the endoscope traversable group), and Group B (the endoscope non-traversable group). We then retrospectively compared the clinical characteristics of these 2 groups.The endoscope non-traversable group (Group B) revealed an advanced clinical stage, a poor Eastern Cooperative Oncology Group (ECOG) score, a lower serum albumin level, a higher rate of requirement for esophageal stent insertion and definitive CRT as initial treatment than the endoscope traversable group (Group A). Patients with endoscope traversable cancer showed a significantly higher 3-year overall survival and 3-year relapse-free survival than patients who were endoscope non-traversable (53.8% vs 17.3%, P squamous cell carcinoma treated with definitive CRT, the serum albumin level squamous cell carcinoma treated with definitive CRT is a significant prognostic factor.

    During the period from January 1983 through September 1986, 13 patients with carcinoma of the breast were treated with local hyperthermia combined with radiotherapy. Six patients were inoperable advanced cases and the other 7 were recurrent cases. Local heat was applied with an 8-MHz RF-capacitive heating equipment, once or twice a week after radiotherapy, for 40 approx. 60 minutes per session. Of the 6 cases with inoperable advanced lesions, 4 achieved CR and the other 2 achieved PRa (80 approx. 100 % regression), and of the 7 cases with local recurrent tumors, 3 achieved CR and the other 4 achieved PRa. As complications of the thermoradiotherapy, grade I-II skin burns were observed in 9 cases, pain around the ribs in 8 cases, mild lassitude in 2 cases, persistent tachycardia in 1 case and acute erosive gastritis in 1 case. It is worth noting that CR was achieved in these huge tumors, which can not be controlled by radiotherapy alone.

    We investigated the efficacy of concurrent chemoradiotherapy (CCRT) over radiotherapy (RT) in Chinese patients with locally advanced cervical carcinoma. Between January 2005 and January 2008, 192 patients with squamous cell carcinoma of the cervix were included in the study: 96 in arm A (CCRT with 20 mg/m 2 cisplatin for 5 days) and 96 in arm B (RT). The overall response rate was the primary endpoint. The secondary endpoints included overall survival, progression-free survival, and toxicity. The 5-year overall response rate was 67% and 53% for the CCRT and RT arms, respectively, and the difference was statistically significant, while the median overall survival was 68 months (range 3-85 months) and 61 months (range 4-83 months), respectively (P = 0.009). In addition, the median progression-free survival for CCRT was 62 months (range 3-83 months), whereas it was 51 months (range 4-81 months) for the RT arm (P = 0.025). The toxicity profile, both acute and late, was comparable in both arms. In summary, we demonstrate that CCRT was effective and better tolerated than RT alone in Chinese patients with locally advanced cervical carcinoma.

    Locally advanced ovarian carcinomas may be fixed to the pelvic sidewall, and although these often involve the internal iliac vessels, they rarely involve the external iliac vessels. Such tumors are mostly considered inoperable. We present a surgical technique for complete resection of locally advanced ovarian carcinoma fixed to the pelvic sidewall and involving external and internal iliac vessels. A 69-year-old woman presented with ovarian carcinoma fixed to the right pelvic sidewall, which involved the right external and internal iliac arteries and veins and the right lower ureter, rectum, and vagina. We cut the external iliac artery and vein at the bifurcation and at the inguinal ligament to resect the external artery and vein. Then, we reconstructed the arterial and venous supplies of the right external artery and vein with grafts. After creating a wide space immediately inside of the sacral plexus to allow the tumor fixed to pelvic sidewall with the internal iliac vessels to move medially, we performed total internal iliac vessel resection. We achieved complete en bloc tumor resection with the right external and internal artery and vein, right ureter, vagina, and rectum adhering to the tumor. There were no intra- or postoperative complications, such as bleeding, graft occlusion, infection, or limb edema. Exfoliation from the sacral plexus and total resection with external and internal iliac vessels enables complete resection of the tumor fixed to the pelvic sidewall. Copyright © 2017 Elsevier Inc.

    Purpose: To evaluate the applicability of carbon ion beams for the treatment of carcinoma of the lacrimal gland with regard to normal tissue morbidity and local tumor control. Methods and materials: Between April 2002 and January 2011, 21 patients with locally advanced primary epithelial carcinoma of the lacrimal gland were enrolled in a Phase I/II clinical trial of carbon-ion radiotherapy (CIRT) at the National Institute of Radiological Sciences. Acute radiation toxicity was the primary endpoint of this dose-escalation study and the late toxicity, local control, and overall survival were additionally evaluated as secondary endpoints. Of the 21 subjects enrolled, all patients were followed for more than 6 months and analyzed. Results: The radiation dose was increased from the initial dose of 48.0 Gy equivalents (GyE)/12 fractions at 10% increments up to 52.8 GyE. Of the 21 patients, five received a total dose of 48.0 GyE, and 16 received a total dose of 52.8 GyE. No patient developed grade 3 or higher skin toxicity. As late ocular/visual toxicity, three patients had grade 3 retinopathy and seven patients lost their vision. Among the 10 patients treated until May 2005, five patients had local recurrence, three of whom had marginal recurrence. Therefore, the margin for the CTV (clinical target volume) was set to a range according to the orbital exenteration since June 2005. After the application of the extended margin, no local recurrence has been observed. The three-year overall survival and local control rates were 82.2% and 79.0%, respectively. Conclusion: CIRT can be applied for primary epithelial carcinoma of the lacrimal gland, with a borderline acceptable morbidity and sufficient antitumor effect when an extended margin is adopted

    Aim: To evaluate the impact of staging FDG PET-CT on the initial management of patients with locally advanced cervical carcinoma (LACC) and any prognostic variables predicting survival. Materials and methods: Retrospective analysis of consecutive patients undergoing FDG PET-CT for staging of LACC in a single tertiary referral centre, between April 2008 and August 2011. Comparison was made between MRI and PET-CT findings and any subsequent impact on treatment intent or radiotherapy planning was evaluated. Results: Sixty-three patients underwent FDG PET-CT for initial staging of LACC. Major impact on management was found in 20 patients (32%), a minor impact in five (8%), and no impact in 38 (60%). In those patients where PET-CT had a major impact, 12 had more extensive local nodal involvement, five had occult metastatic disease, two had synchronous tumours, and one patient had equivocal lymph nodes on MRI characterized as negative. PET-positive nodal status at diagnosis was found to be a statistically significant predictor of relapse-free survival (p < 0.05). Conclusion: Staging FDG PET-CT has a major impact on the initial management of approximately one-third of patients with LACC by altering treatment intent and/or radiotherapy planning. PET-defined nodal status is a poor prognostic indicator. - Highlights: • Cervical carcinoma is one of the commonest cancers in women worldwide. • Locally advanced cervical carcinoma is usually treated with chemo-radiotherapy. • FDG PET-CT can have a major impact on management in up to one-third of patients. • It may alter treatment intent or radiotherapy-planning by detecting occult disease. • PET nodal status at diagnosis is an important predictor of relapse-free survival

    Background and purpose: This phase II study evaluated the efficacy and toxicity of weekly cisplatin along with concomitant boost accelerated radiation regimen in patients with locally advanced unresectable head and neck carcinoma. Material and methods: A total of 94 patients (median age, 58 years) with UICC stage III (n=19) and IV (n=75) cancer of the oropharynx, larynx, hypopharynx and oral cavity were included. Patients received radiotherapy with a concomitant boost scheme (1.8 Gy on days 1-40 and 1.5 Gy boost on days 25-40 with a total dose of 72 Gy) and concurrent cisplatin, 40 mg/m 2 weekly, for the first 4 weeks. Results: Most patients (95%) received both radiation and chemotherapy according to protocol. Toxicity was manageable with grade III mucositis and pharyngeal-oesophageal toxicity in 85 and 50% of patients, respectively. Haematological toxicity was mild. Four patients (4%) died due to complications. With a median follow of 41 months, median overall survival and time to progression were 27 and 25 months, respectively. The estimated overall survival at 4 years was 41%. Conclusions: Concomitant boost accelerated radiation plus concurrent weekly cisplatin is a feasible schedule in patients with locally advanced unresectable head and neck carcinoma, with acceptable toxicity and survival data

    Despite improvements in surgical techniques and treatments introduced into clinical practice, the overall survival of patients with esophageal squamous cell carcinoma remains low. Several epidermal growth factor receptor inhibitors are being evaluated in the context of clinical trials, but there is little evidence of effectiveness in real-world conditions. This study aimed at assessing the effectiveness of nimotuzumab combined with onco-specific treatment in Cuban real-life patients with locally advanced or metastatic esophageal squamous cell carcinoma. A comparative and retrospective effectiveness study was performed. The 93 patients treated with nimotuzumab were matched, with use of propensity score matching, with patients who received a diagnosis of locally advanced or metastatic squamous cell carcinoma of the esophagus in three Cuban provinces reported between 2011 and 2015 to the National Cancer Registry. The Kaplan-Meier method was used to estimate event-time distributions. Log-rank statistics were used for comparisons of overall survival between groups. A two-component mixture model assuming a Weibull distribution was fitted to assess the effect of nimotuzumab on short-term and long-term survival populations. There was an increase in median overall survival in patients treated with nimotuzumab (11.9 months versus 6.5 months without treatment) and an increase in the 1-year survival rate (54.0% versus 21.9% without treatment). The 2-year survival rates were 21.1% for patients treated with nimotuzumab and 0% in the untreated cohort. There were statistically significant differences in survival between groups treated and not treated with nimotuzumab, both in the short-term survival population (6.0 months vs 4.0 months, p = 0.009) and in the long-term survival population (18.0 months vs 11.0 months, p = 0.001). Our study shows that nimotuzumab treatment concurrent with chemoradiotherapy increases the survival of real-world patients with locally advanced

    Full Text Available Background: Oral cavity cancer is a significant health problem in India. Majority of patients present with locally advanced disease requiring multimodality treatment. Compliance to recommended treatment is an important factor affecting outcome. Aims: The aim was to evaluate the outcome of locally advanced oral cavity cancer patients with regards to treatment adherence and to assess reasons of noncompliance. Materials and Methods: This was a prospective observational study. We included patients referred to Department of Medical Oncology for induction chemotherapy in view of locally advanced oral cavity cancer. Results: Only 15 (26% patients completed planned treatment schedule. Their 1 year overall survival was 93%. The remaining 43 patients who received inadequate treatment had a dismal 21% 1 year overall survival. Illiteracy, poverty, long waiting list for surgery, prolonged delay for health scheme treatment plan approval and dissatisfaction with attitude of hospital staffs are major barriers related to effective treatment of these patients. Conclusions: A detailed discussion with patient and their relatives regarding recommended treatment, proper implementation of health schemes, increasing trained manpower to avoid long waiting list for surgery, provision of additional financial support for family member accompanying the patient and a sympathetic approach toward patients are needed to help these patients overcome the battle.

    Background: Squamous cell carcinoma of the cheek is a locoregionally aggressive tumor. Radical resection may be curative in cases of large tumor without distant metastases. We reviewed forty eight consecutive cases of Sq.c.c. of the oral cavity to evaluate the feasibility and efficacy of the reconstructive method. Patients and Methods: Forty eight cases of invasive Sq.c.c. affecting the cheek performed in Mansoura University, Surgical Oncology Department. From November 2001 to October 2004 were included. Twenty cafes presented primarily, and 28 were relapsing after previous surgery or radiotherapy. Tumors of T 3 and T 4 size were included. Radical excision with adequate safety margin followed by reconstruction was done in the same setting using: A- Double layered pectorals major flap (n=30). B- Pectorals major flap for external surface and tongue flap for mucosal lining (n=10). C- Pectorals major flap plus free Latissmus dorsi flap (n=3). D- Latissmus dorsi flap plus tongue flap (n=5). Results: Nine cases (18.7%) had local and distant relapse after a median follow up period of 36 months. However, total flap loss was not encountered. There were partial loss of three tongue flaps, seven pectorals flaps corrected with debridement and re approximation. Two patients had oral incompetence. Orocutaneous salivary fistula persistent more than three weeks occurred in eight patients. Functional outcome in terms of oral competence, sensibility, chewing movements was satisfactory in all but three cases. In Conclusion: Radical resection of extensive cheek carcinoma and reconstruction using pedicled flaps is an effective, economic and reliable method for oncologic and functional purposes

    Concurrent chemoradiotherapy (CRT) using cisplatin (CDDP) and 5-fluorouracil (5-FU) is the standard treatment for unresectable locally advanced esophageal carcinoma. Although this regimen has been widely accepted in Japan, the adverse effect of CDDP such as gastrointestinal and renal toxicity may sometimes be the cause of interruption of the treatment, especially among the elderly patients. Cis-diammine-glycolatoplatinum (nedaplatin: CDGP) is a new platinum agent, which was developed with the aim of decreasing renal and gastrointestinal toxicities but maintaining the effectiveness of CDDP. We reported the efficacy and safety of CRT using CDGP and 5-FU for locally advanced squamous cell carcinoma of the esophagus. Between January 2001 and December 2007, 65 patients with locally advanced esophageal cancer (39 patients with unresectable tumor (cT4) and 26 patients with distant lymphnode or bulky lymphnode metastasis) were eligible and given informed consent and cared by the Department of Surgical Oncology of Osaka City University. Patients received a continuous infusion of 5-FU (250 mg/body) on days 1-21. CDGP was administered at the dose of 10 mg/body by bolus infusion for 1 hour on days 1-5, 8-12 and 15-19 just before radiotherapy. Radiotherapy was delivered in 1.8 Gy fractions, 5 days/week for 4 weeks. For the effective cases of CRT, a surgical resection was followed subsequently and an additional radiotherapy at the dose of 20 Gy was performed for non-effective cases. Complete or partial response was achieved in 46 patients (71%). Hematologic toxicities such as grades 3 and 4 leucocytopenia developed in 19 patients and thrombocytopenia developed in 20 patients, which were well tolerated by conservative therapy. Gastrointestinal and renal toxicities were developed in only a few patients. There was no CRT-related death. Of all 65 patients, 25 patients underwent a surgical resection while 19 patients could receive a curative resection (R0 operation). In the resected

    A significant correlation has been found between p53 mutation and response to chemotherapy or radiotherapy. To determine the prognostic value of p53 mutation in patients with locally advanced esophageal carcinoma treated with definitive chemoradiotherapy, p53 mutation was analyzed using the biopsied specimens taken for diagnosis. Concurrent chemoradiotherapy was performed for 40 patients with severe dysphagia caused by esophageal squamous cell carcinoma associated with T3 or T4 disease. Chemotherapy consisted of protracted infusion of 5-fluorouracil, combined with an infusion of cisplatinum. Radiation treatment of the mediastinum was administered concomitantly with chemotherapy. The p53 gene mutation was detected by fluorescence-based polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) methods. DNA sequences were determined for DNA fragments with shifted peaks by SSCP methods. Of the 40 patients, 15 had T3 disease and 25 had T4 disease; 11 patients had M1 lymph node (LYM) disease. Of the 40 patients, 13 (33%) achieved a complete response. The median survival time was 14 months, and the 2-year survival rate was 20%. Among the 40 tumor samples, p53 mutation was detected in 24 tumors (60%). The survival rate in the 24 patients with p53 mutation did not differ significantly from that in the 16 patients without p53 mutation. In contrast, the 15 patients with T3 disease survived longer than the 25 patients with T4 disease (P=0.016); however, the survival rate in the 11 patients with M1 LYM disease did not differ significantly from that in the 29 patients without M1 LYM disease. Concurrent chemoradiotherapy is potentially curative for locally advanced esophageal carcinoma, but p53 genetic abnormality has no impact on prognosis. (author)

    Objective: To research the early effects and side-effects of the local advanced nasopharyngeal carcinoma patients using intensity-modulated radiotherapy (IMRT) combined with concurrent chemotherapy. Methods: From January 2005 to January 2007, 60 patients with nasopharyngeal carcinoma of stage m-IV b were received IMRT combined with concurrent chemotherapy in our center. Sixty patients were divided into paclitaxel concurrent group (32 patients) and cisplatin concurrent group (28 patients). The prescribing doses of the primary tumor were 68-72 Gy for each group. The patients of paclitaxel concurrent group received 5-7 times pacitaxel liposome chemotherapy of 30 mg · m -2 ·. The patients of cisplatin concurrent group received 5-7 times cisplatin chemotherapy of 30 mg · m -2 · week -1 . Results: As to the side-effects, the patients of the cisplatin concurrent group got earlier radiodermatitis and radiation-induced mucositis but also got significantly higher rate of radiodermatitis, radiation-induced mucositis, radiation-induced leucopenia and gastrointestinal toxicity, as well as the loss of weight. No significant difference was found on liver and renal functions between two groups.Four patients (12.5%) of the paclitaxel concurrent group were broken-off, which was much better than the cisplatin concurrent group. There was no significant difference on the specific length of break-off time, the 2-year overall survival rate and the 2-year diseaee-free survival rate between two groups. Conclusions: IMRT combined with concurrent chemotherapy of paclitaxel liposome for local advanced nasopharyngeal carcinoma results in less side-effects and better tolerance than IMRT combined with concurrent cisplatin chemotherapy.

    Most patients with squamous cell carcinoma (SCC) present with advanced or metastatic disease at the time of diagnosis. Given the low prevalence of oncogenic driver mutations in SCC, I do not routinely perform molecular testing. The times that I perform molecular testing in SCC are for patients with SCC and a light or never smoking history, adenosquamous histology, or when the histological diagnosis is not definitive. For patients with a good performance status and adequate organ function, a platinum doublet is the standard therapy, and I generally use carboplatin and gemcitabine or carboplatin and paclitaxel. In the second-line setting for patients who are chemotherapy candidates, I will use docetaxel on a weekly or every three week schedule. Erlotinib is a treatment option in the third-line setting. My preference is for patients to participate in clinical trials because the development of novel therapies for patients with SCC has been slow compared with nonsquamous non-small cell lung cancer. Ongoing investigations into the genomics of SCC will hopefully identify driver mutations or alterations in pathways essential for oncogenesis and tumor growth and will lead to the development of targeted therapies. The complexity of the genomics of SCC will make the development of targeted therapies challenging.

    Full Text Available This retrospective study aims to examine the association of plasma Epstein-Barr virus- (EBV- DNA levels with the tumor volume and prognosis in patients with locally advanced nasopharyngeal carcinoma (NPC. A total of 165 patients with newly diagnosed locally advanced NPC were identified from September 2011 to July 2012. EBV-DNA was detected using fluorescence quantitative polymerase chain reaction (PCR amplification. The tumor volume was calculated by the systematic summation method of computer software. The median copy number of plasma EBV-DNA before treatment was 3790 copies/mL. The median gross tumor volume of the primary nasopharyngeal tumor (GTVnx, the lymph node lesions (GTVnd, and the total GTV before treatment were 72.46, 23.26, and 106.25 cm3, respectively; the EBV-DNA levels were significantly correlated with the GTVnd and the total GTV (P<0.01. The 2-year overall survival (OS rates in patients with positive and negative pretreatment plasma EBV-DNA were 100% and 98.4% (P=1.000, and the disease-free survival (DFS rates were 94.4% and 80.8% (P=0.044, respectively. These results indicate that high pretreatment plasma EBV-DNA levels in patients with locally advanced NPC are associated with the degree of lymph node metastasis, tumor burden, and poor prognosis.

    Purpose: To evaluate the toxicity and efficacy of carbon ion radiotherapy (CIRT) for locally advanced cervical cancer by two phase I/II clinical trials. Methods and Materials: Between June 1995 and January 2000, 44 patients were treated with CIRT. Thirty patients had Stage IIIB disease, and 14 patients had Stage IVA disease. Median tumor size was 6.5 cm (range, 4.2-11.0 cm). The treatment consisted of 16 fractions of whole pelvic irradiation and 8 fractions of local boost. In the first study, the total dose ranged from 52.8 to 72.0 gray equivalents (GyE) (2.2-3.0 GyE per fraction). In the second study, the whole pelvic dose was fixed at 44.8 GyE, and an additional 24.0 or 28.0 GyE was given to the cervical tumor (total dose, 68.8 or 72.8 GyE). Results: No patient developed severe acute toxicity. In contrast, 8 patients developed major late gastrointestinal complications. The doses resulting in major complications were ≥60 GyE. All patients with major complications were surgically salvaged. The 5-year local control rate for patients in the first and second studies was 45% and 79%, respectively. When treated with ≥62.4 GyE, the local control was favorable even for the patients with stage IVA disease (69%) or for those with tumors ≥6.0 cm (64%). Conclusions: In CIRT for advanced cervical cancer, the dose to the intestines should be limited to <60 GyE to avoid major complications. Although the number of patients in this study was small, the results support continued investigation to confirm therapeutic efficacy

    The successful treatment of a patient with bulky squamous cell carcinoma of the urethra using low dose preoperative radiation therapy and concurrent chemotherapy is described. Dramatic rapid tumor response facilitated surgical resection of the remaining microscopic disease. This clinical behavior is remarkably similar to that seen with squamous cell carcinoma of the anal canal and esophagus when a similar regimen is used. At the latter tumor sites the successful use of combination radiotherapy and chemotherapy has reduced the morbidity of subsequent surgery, and in selected cases has obviated the need for a radical operation. Further investigation of such combination treatment is warranted for urethral carcinoma

    Locally advanced (pT3-4N0M0) hepatocellular carcinoma (HCC) is a heterogeneous group of tumors, which consists of four different categories, including HCC with 'multiple tumors more than 5 cm', 'major vascular invasion', 'invasion of adjacent organs', and 'perforation of visceral peritoneum'. The aim of our study was to verify whether the 2002 version of the Tumor-Node-Metastasis staging system could predict surgical outcomes in patients with locally advanced HCC. We retrospectively reviewed 298 patients with pT3-4N0M0 HCC who underwent hepatic resection from 1993 to 2000 in an academic tertiary hospital. Overall survival (OS) and cumulative recurrence rate (CRR) of the four categories of locally advanced HCC patients were compared. In multivariate analysis, major vascular invasion was identified as the most significant factor (HR = 3.291, 95% CI 2.362-4.584, P < 0.001) followed by cirrhosis status on OS, and was found to be the only independent factor of CRR (HR = 2.242, 95% CI 1.811-3.358, P < 0.001) in patients with locally advanced HCC. Among the four categories of locally advanced HCC, OS was significantly worse, and CRR was significantly higher in patients with HCC with major vascular invasion (pT3) than with multiple tumors more than 5 cm (pT3); or tumor invasion of adjacent organs (pT4); or perforation of visceral peritoneum (pT4). No significant differences were observed in OS or CRR between the latter three groups of patients. HCC with major vascular invasion, which are classified as pT3 under the current TNM staging, have the worst prognosis when compared with the other categories of pT3-4 disease. There is a need to redefine the T classification and to stratify locally advanced HCC

    During the period from January 1983 through September 1986, 13 patients with carcinoma of the breast were treated with local hyperthermia combined with radiotherapy. Six patients were inoperable advanced cases and the other 7 were recurrent cases. Local heat was applied with an 8-MHz RF-capacitive heating equipment, once or twice a week after radiotherapy, for 40 ∼ 60 minutes per session. Of the 6 cases with inoperable advanced lesions, 4 achieved CR and the other 2 achieved PRa (80 ∼ 100 % regression), and of the 7 cases with local recurrent tumors, 3 achieved CR and the other 4 achieved PRa. As complications of the thermoradiotherapy, grade I-II skin burns were observed in 9 cases, pain around the ribs in 8 cases, mild lassitude in 2 cases, persistent tachycardia in 1 case and acute erosive gastritis in 1 case. It is worth noting that CR was achieved in these huge tumors, which can not be controlled by radiotherapy alone. (author)

    Purpose: When associated with radiotherapy the monoclonal antibodies such as cetuximab might be exacerbate skin toxicity. The aim of this study was to retrospectively analyze acute dermatological toxicity in ten consecutive patients with locally advanced head and neck squamous cell carcinoma treated from march 2008 to May 2009 according to Bonner protocol. Patients and methods: We have treated with radiotherapy and cetuximab ten patients with locally advanced head and neck squamous cell carcinoma of the oropharynx, hypopharynx, larynx or oral cavity, stage 3-4B and non metastatic. All our patients were 3D planned and scheduled for conventional fractionation 70 Gy/35 fractions over 47 days, five days weekly. Uninvolved neck received 50 Gy and gross nodal disease received 70 Gy as the primary tumor. Cetuximab was administered one week before radiotherapy at a loading dose of 400 mg per square meter of body surface area over 120 minutes, followed by weekly 60 minutes infusions at 250 mg per square meter for the duration of radiotherapy. Results: In eight patients (80%) grade 3 radiation dermatitis occurred as early as with 28 Gy at a median dose of 42 Gy (range 28-60 Gy). the median radiotherapy dose was 6 Gy with an overall treatment time of 57.7 days (range 41-70 days). were administered 78 cycles of cetuximab, one patient discontinued after five cycles due to infusion reactions. There was no correlation between toxicity and acne-like rash due to cetuximab. Conclusion: Our results albeit in disagreement with the original study are rather similar with the experience of other European centers that encounter grade 3-4 radiation dermatitis in 49% of their patients or Australian centers that reported 79% of same degree of toxicity.

    Background: Rectal carcinoma [RC] is often managed with preoperative radiotherapy or radio chemotherapy followed by total meso rectal excision (TME). Efforts are being made to improve outcome by intensifying the preoperative treatment. However, the optimum therapy remains unclear. There is ongoing controversy regarding the optimum radiation dose, chemotherapy regimen and schedule. In addition there exists growing disagreement regarding the role of adjuvant chemotherapy after neoadjuvant radiation or chemo radiation. Methodology: We reviewed the recent land mark trials to find a road map in the management of locally advanced rectal carcinoma. Results: Preoperative short course radiotherapy has long been proven to improve local disease con- trol. The initial trials with long course chemoradiotherapy, comparing short course radiotherapy have shown to increase local control and pathological complete response rates. Since then treatment intensification of this neoadjuvant schedule has been tried by many researchers. But initial results of these treatment intensification trials, show no significant benefit and are associated with increased toxicity. There is an unmet need to stratify patients depending on risk to assign them to long course chemoradiotherapy or short course radiotherapy. Current evidence does not support the use of adjuvant chemotherapy in patients who were treated with preoperative (chemo)radiotherapy. Conclusion: Preoperative radiotherapy appears to improve disease control with favorable toxicity profile and there is very little to choose between long course chemoradiotherapy and short course radiotherapy. However, long course chemoradiotherapy may be beneficial for patients with high risk features like positive circumferential resection margin [CRM] and extramural spread of >5 mm. There is no role for adjuvant chemotherapy in patients who were treated preoperative (chemo)radiotherapy

    The goal of the present work was to compare outcomes of definitive concurrent cisplatin-based chemoradiotherapy (CRT) with cetuximab-based bioradiotherapy (BRT) in locally advanced head-and-neck squamous cell carcinoma (HNSCC). Between 2006 and 2012, 265 patients with locally advanced HNSCC were treated at our institution with CRT (n = 194; 73 %) with three cycles of cisplatin (100 mg/m 2 , every 3 weeks) or BRT (n = 71; 27 %) with weekly cetuximab. Patients receiving BRT had more pre-existing conditions (Charlson index ≥ 2) than the CRT group (p = 0.005). Median follow-up was 29 months. In all, 56 % of patients treated with CRT received the planned three cycles (92 % at least two cycles) and 79 % patients treated with BRT received six cycles or more. The 2-year actuarial overall survival (OS) and progression-free survival (PFS) were 72 % and 61 %, respectively. In the multivariate analysis (MVA), T4 stage, N2-3 stage, smoking status (current smoker as compared with never smoker), and non-oropharyngeal locations predicted for OS, whereas BRT association with OS was of borderline significance (p = 0.054). The 2-year actuarial locoregional control (LRC) and distant control (DC) rates were 73 and 79 %, respectively. CRT was independently associated with an improved LRC (2-year LRC: 76 % for CRT vs. 61 % for BRT) and DC (2-year LRC: 81 % for CRT vs. 68 % for BRT) in comparison with BRT (p [de

    Prospective, single arm. Phase I/II clinical trial was performed to assess the efficacy and toxicity of the concurrent chemotherapy and definitive radiotherapy (RT) in patients with previously untreated locally advanced carcinoma of the uterine cervix. From May 1992 to January 1997, a total of 73 patients with advanced cervical carcinoma were entered on the protocol but 5 patients were excluded in analysis because of patients' refusal of treatment. Their ages ranged from 31 to 77 years, median 58 years. The international Federation of Gynecology and Obstetrics (FIGO) stage distribution was as follows: IIB 46, IIIA 2, IIIB 15 and IVA 5. RT consisted of external beam irradiation to 4, 140-5, 040 cGy/23-28 fractions plus high dose rate intracavitary treatments to deliver a dose of 30-35 Gy to point A in 6-7 fractions. During the intracavitary treatments parametrial boost was delivered for point B dose of 60 Gy in stage IIB and 65 Gy in stage IIIB. Two cycles of concurrent 5-fluorouracil and cisplatin (FP) chemotherapy (5-fluorouracil 1,000 mg/m 2 /day continuous infusion for 4 days, day 1-4, 29-32 and cisplatin 20 mg/m 2 /dy intravenous bolus for 3 days, day 1-3, 29-31) administered starting on day 1 of 1 of RT. The median follow-up was 24 months (range 4-68+). Sixty-four patients were evaluable for survival rate in this protocol: The 5-year actuarial and disease-free survival rate were 52% and 64%, respectively. The 5-year actuarial survival for stage IIB and II+IVA patients were 58% and 36%, respectively. The 5-year disease-free survival rate for stage IIB and III+IVA patients were 71% and 46%, respectively. Of the 68 patients evaluated for patterns of failure, overall recurrence rate was 27.9% (19/68): local failure in 5.9% (4/68), distant metastasis in 10.3% (7/68) and both in 11.8% (8/68). Of the 64 patients evaluated for response at one month after the completion of treatment, the complete response rate was 78% (50/64). Concurrent chemoradiation appear to be a

    Full Text Available We retrospectively analyzed 14 patients with locally advanced squamous cell carcinoma of ethmoid sinus (LASCC-ES for the feasibility of anterior craniofacial resection (ACFR. Ethmoid cancer treatment comprised alternating chemoradiotherapy (ALCRT; n = 1, concomitant radiotherapy and intra-arterial cisplatin (RADPLAT; n = 4 and ACFR (n = 9. The 3- and 5-year overall survival (OS rates of patients were 47.6 and 39.6%, respectively. The 3-year local control (LC rates of chemoradiotherapy (CRT; ALCRT and RADPLAT (n = 5 and ACFR (n = 9 groups were 0 and 66.7% (p = 0.012, respectively. The 3-year progression-free survival (PFS rate of the CRT and ACFR groups were 0 and 55.6% (p = 0.018, respectively. The 3-year OS rate of the CRT and ACFR groups were 0 and 76.2% (p = 0.005, respectively. Postoperative pathological examinations confirmed positive margins in 3 (33% of 9 cases. The 3-year LC and PFS rates of cases (n = 3 with positive surgical margins were significantly poorer than those of cases (n = 6 with negative surgical margins. Although ACFR for LASCC-ES is a feasible treatment, cases with positive surgical margins were more prone to local relapse. Therefore, surgical safety margins should be thoroughly assessed.

    We investigated the tolerability of cetuximab plus radiotherapy in Japanese patients with untreated locally advanced squamous cell carcinoma of the head and neck. Patients with epidermal growth factor receptor-expressing locally advanced squamous cell carcinoma of the head and neck received cetuximab (400 mg/m 2 initial dose then 250 mg/m 2 weekly) for 7 weeks plus concomitant boost radiotherapy (weeks 2-7: once daily [1.8 Gy] for 3.6 weeks, then twice daily [1.8 Gy morning and 1.5 Gy afternoon] for 2.4 weeks). The primary endpoint was treatment completion rate (the rate of treated patients completing ≥70% of the planned cetuximab dose and the full dose of radiotherapy within 2 weeks over the planned schedule). Twenty-two patients were evaluable. The treatment completion rate was 100% (95% confidence interval 85-100). The response rate 8 weeks post-radiotherapy was 82% (95% confidence interval 60-95). The most common grade 3/4 treatment-emergent adverse events were mucosal inflammation (73%); dermatitis (27%); and infection, radiation skin injury and stomatitis (23% each). Cetuximab plus concomitant boost radiotherapy can be safely administered to Japanese patients with locally advanced squamous cell carcinoma of the head and neck. Tolerability and efficacy were in line with those reported in the Phase III Bonner trial in a Western population of patients with locally advanced squamous cell carcinoma of the head and neck.

    Background. The optimal care for patients with unresectable, non-metastatic pancreatic adenocarcinoma (PAC) is debated. We treated 17 consecutive cases with preoperative radiochemotherapy (RCT) as a means for downstaging their tumours and compared outcome with 35 patients undergoing direct surgery for primarily resectable PAC during the same time period. Methods. The patients had biopsy proven, unresectable, non-metastatic PAC which engaged ≥ 50% of the circumference of a patent mesenteric/portal vein for a distance ≥ 2 cm and/or 2 d1; capecitabine 2 000 mg/m 2 d1-14 q 3 w) followed by 3-D conformal radiotherapy (50.4 Gy; 1.8 Gy fractions) with reduced Xelox (d1-5 q 1 w X 6). Results. No incident of RCT-related CTC Grade 3-4 haematologic and six cases of non-haematologic side-effects were diagnosed. Sixteen patients completed the RCT and were rescanned with CT and reevaluated for surgery 4 weeks post-RCT. Five cases were diagnosed with new metastases to the liver. Eleven patients were accepted for surgery whereof eight underwent a curative R 0 -resection. The median overall survival for the latter group was 29 months, which compared favourably with our control group of patients undergoing direct curative surgery for primarily resectable PAC (median OS: 16 months; RO-rate: 75%). Perioperative morbidity was similar in the two cohorts but the duration of surgery was longer (576 vs. 477 min) and the op blood loss was greater (3288 vs. 1460 ml) in the RCT-cohort (p < 0.05). The 30-day mortality was zero in both groups. Conclusion. Preoperative RCT in patients with locally advanced PAC resulted in a high rate of curative resections and promising median survival in our treatment series. This trimodality approach merits further exploration in new studies, which are currently underway at our Dept

    Saliva from submandibular glands (SMG) is necessary to minimize xerostomia. It is unclear whether SMG can be safely spared in patients undergoing bilateral neck radiotherapy for locally advanced oropharyngeal cancer without increasing the risk of marginal recurrence. We evaluated the outcomes of contralateral submandibular gland (cSMG) sparing intensity-modulated radiation therapy (IMRT). All patients with stage III/IV oropharyngeal squamous cell carcinoma treated with bilateral neck IMRT from 2006–2012 at our institution were included. Appropriately selected patients with favorable primary tumor characteristics and no definite contralateral neck disease were treated with cSMG-sparing IMRT. Patterns of failure and xerostomia outcomes were retrospectively analyzed. 114 patients were treated. 89% had stage IV disease and 89% received definitive radiation therapy. 76 patients (67%) received cSMG sparing IMRT. With a median follow-up of 30 months, there were 10 local, 9 regional, and 10 distant recurrences. 2-year overall survival was 86% and 2-year loco-regional control was 87%. In cSMG spared patients, the mean cSMG dose was 30.7 Gy. Late grade 2+ xerostomia was significantly reduced in the cSMG spared group compared to those without SMG sparing (6 months: 23% vs. 72%, 12 months: 6% vs. 41%, 24 months: 3% vs. 36%, all p < 0.0007). There were no peri-SMG marginal recurrences in the cSMG-spared cohort. cSMG sparing IMRT did not increase marginal failures in this series of locally advanced oropharyngeal SCC patients. Xerostomia was significantly reduced in cSMG spared patients

    To compare surgery and postoperative radiotherapy (PORT) with the non-surgical combination of chemotherapy and radiation therapy (CCRT) for locally advanced squamous cell carcinoma (SCC) of the tonsil by measuring treatment outcomes and treatment-related complications. The records of 114 patients with non-metastatic stage III/IV tonsillar SCC treated between July, 1998 and December, 2010 were reviewed retrospectively. Among the 114 patients, 65 received PORT and 49 received CCRT. In the PORT group, treatment included wide surgical resection of the tumor with neck dissection and administration of PORT to the primary tumor bed with a median dose of 60 Gy. In the CCRT group, a median dose of 70 Gy was delivered to the gross tumor, and 46 patients received concurrent chemotherapy with i.v. cisplatin. The median follow-up time was 58 months in the PORT group and 44 months in the CCRT group. There was no significant difference between PORT and CCRT in terms of 5-year locoregional recurrence-free survival (88.4% vs. 91.4%, p=0.68), distant metastasis-free survival (88.9% vs. 92.3%, p=0.60), disease-free survival (79.5% vs. 84.2%, p=0.63) or overall survival (78.9% vs. 88.9%, p=0.45). More CCRT patients than PORT patients experienced grade 3 (or higher) hematological toxicities and grade 2 pharyngitis during treatment. Chronic toxicity, manifested as swallowing difficulty, dry mouth and trismus, was similar between the two treatment groups. CCRT provides similar levels of local and distant control in patients with locally advanced tonsillar SCC as PORT, yet fails to show any superiority in preserving functions such as swallowing, saliva production, and mastication.

    Objectives: To study the effect of adding chemotherapy to radiotherapy (RT) on overall survival and event-free survival for patients with nasopharyngeal carcinoma. Methods and Materials: This meta-analysis used updated individual patient data from randomized trials comparing chemotherapy plus RT with RT alone in locally advanced nasopharyngeal carcinoma. The log-rank test, stratified by trial, was used for comparisons, and the hazard ratios of death and failure were calculated. Results: Eight trials with 1753 patients were included. One trial with a 2 x 2 design was counted twice in the analysis. The analysis included 11 comparisons using the data from 1975 patients. The median follow-up was 6 years. The pooled hazard ratio of death was 0.82 (95% confidence interval, 0.71-0.94; p = 0.006), corresponding to an absolute survival benefit of 6% at 5 years from the addition of chemotherapy (from 56% to 62%). The pooled hazard ratio of tumor failure or death was 0.76 (95% confidence interval, 0.67-0.86; p < 0.0001), corresponding to an absolute event-free survival benefit of 10% at 5 years from the addition of chemotherapy (from 42% to 52%). A significant interaction was observed between the timing of chemotherapy and overall survival (p = 0.005), explaining the heterogeneity observed in the treatment effect (p = 0.03), with the highest benefit resulting from concomitant chemotherapy. Conclusion: Chemotherapy led to a small, but significant, benefit for overall survival and event-free survival. This benefit was essentially observed when chemotherapy was administered concomitantly with RT

    Full text:Aim: The aim of our study was to correlate 18F-FDG PET response to neoadjuvant chemoradiotherapy with histopathology in patients with locally advanced non-small cell lung carcinoma. Methods: All patients with stage III NSCLC planned for surgery following induction chemotherpay and/or radiotherapy who underwent pre- and post-treatment FDG-PET between 2004 and 2007 were retrospectively reviewed. The PET scans were performed according to standard protocol. The clinical FDG-PET TNM stage was correlated with the histopathology of the surgical specimens. Results: There were 9 patients (6 M :3 F ), median age 59.7 years (range 49 to 73 years). Post-treatment FDG-PET correctly predicted mediastinal pathological N stage in 8/9 patients, with one patient having microsopic disease in two nodes. The post-treatment FDG-PET correctly predicted pathological T stage in 7/9 patients, with 2 patients having small volume T4 disease not detected by PET. Post-treatment FDG-PET correctly downstaged 4 patients. Of the 5 patients, incorrectly staged on the post-treatment FDG-PET, one patient had microscopic pN 2 disease, 2 had pN 1 disease, and 2 had pT 4 disease. Conclusion: Post-treatment FDG-PET is predictive of pathological nodal stage within the mediastinum in patients with locally advanced NSCLC treated with neoadjuvant chemoradiotherapy. FDG-PET does not detect microscopic or small volume disease, nor is it able to define the boundaries of mediastinal tissue invasion.

    Vorinostat is a histone deacetylase inhibitor (HDACi). Based on a confirmed partial response (PR) in an adenoid cystic carcinoma (ACC) patient treated with vorinostat in a prior phase 1 trial, we initiated this phase 2 trial. Vorinostat was administered orally 400 mg daily, 28 day cycles. The primary objective was to evaluate response rate (RR). Exploratory studies included whole exome sequencing (WES) of selected patients. Thirty patients were enrolled. Median age of patients was 53 years (range 21-73). Median number of cycles was 5 (range 1-66). Lymphopenia (n = 5), hypertension (n = 3), oral pain (n = 2), thromboembolic events (n = 2) and fatigue (n = 2) were the only grade 3 adverse events (AEs) that occurred in more than 1 patient. Eleven patients were dose reduced secondary to drug-related AEs. Two patients had a partial response (PR), with response durations of 53 and 7.2 months. One patient had a minor response with a decrease in ascites (for 19 cycles). Stable disease was the best response in 27 patients. Targeted and WES of 8 patients in this trial identified mutations in chromatin remodeling genes highlighting the role of the epigenome in ACC. Vorinostat demonstrated efficacy in patients with ACC supporting the inclusion of HDACi in future studies to treat ACC.

    To evaluate the experience of induction chemotherapy followed by concurrent chemoradiationwith helical tomotherapy (HT) for nasopharyngeal carcinoma (NPC). Between August 2006 and December 2009, 28 patients with pathological proven nonmetastatic NPC were enrolled. All patients were staged as IIB-IVB. Patients were first treated with 2 to 3 cycles of induction chemotherapy with EP-HDFL (Epirubicin, Cisplatin, 5-FU, and Leucovorin). After induction chemotherapy, weekly based PFL was administered concurrent with HT. Radiation consisted of 70 Gy to the planning target volumes of the primary tumor plus any positive nodal disease using 2 Gy per fraction. After completion of induction chemotherapy, the response rates for primary and nodal disease were 96.4% and 80.8%, respectively. With a median follow-up after 33 months (Range, 13-53 months), there have been 2 primary and 1 nodal relapse after completion of radiotherapy. The estimated 3-year progression-free rates for local, regional, locoregional and distant metastasis survival rate were 92.4%, 95.7%, 88.4%, and 78.0%, respectively. The estimated 3-year overall survival was 83.5%. Acute grade 3, 4 toxicities for xerostomia and dermatitis were only 3.6% and 10.7%, respectively. HT for locoregionally advanced NPC is feasible and effective in regard to locoregional control with high compliance, even after neoadjuvant chemotherapy. None of out-field or marginal failure noted in the current study confirms the potential benefits of treating NPC patients by image-guided radiation modality. A long-term follow-up study is needed to confirm these preliminary findings

    The combination of cisplatin and 5-fluorouracil (PF) is currently considered a standard and effective regimen for the treatment of advanced head and neck carcinomas. The aim of this study was to evaluate the efficacy and safety of docetaxel, cisplatin and 5-fluorouracil (TPF) in patients with unresectable head and neck carcinomas. Forty-six patients with previously untreated non-metastatic stage IV head and neck carcinomas were enrolled. All patients received three cycles of induction chemotherapy with docetaxel (75 mg/m(2)), cisplatin (40 mg/m(2)) (days 1-2), and 5-FU (500 mg/m(2), days 1-3), repeated every 21 days. Following induction chemotherapy, all patients underwent concurrent chemoradiotherapy using weekly cisplatin (30 mg/m(2)) and a median total dose of 70 Gy was delivered. Clinical response rate and toxicity were the primary and secondary end-points of the study. There were 31 men and 15 women. All patients had non-metastatic stage IV (T2-3N2-3 or T4N0-3) of disease. Overall and complete response rates were 74% and 24% respectively. Advanced T4 classification was associated with poorer response rate (p value=0.042). The major (grade 3-4) treatment-related toxicities were myelosuppression (78%), anorexia (13%), diarrhea (7%), emesis (11%) and stomatitis/pharyngitis (24%). In comparison with the data of historical published trials of the PF regimen, the TPF regimen was more effective. However, the TPF regimen appears to be associated with a higher incidence of major toxicities. Therefore, our limited findings support the TPF regimen as an alternative chemotherapeutic regimen for advanced head and neck carcinomas.

    Objective: To investigate the prognostic value of overall treatment time (OTT) for locally advanced nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Methods: From May 2001 to April 2007, 376 patients with locally advanced NPC treated with IMRT were retrospectively analyzed. All patients were divided into OTT≤45 days group and OTT >45 days group. The treatment outcomes between the two groups were analyzed. Results: Between the groups with OTT≤45 days and OTT > 45 days, the 2-year local control rate (LCR) was 94.9% and 93.1% (χ 2 = 2.83, P > 0.05) for all patients, 96.3% and 98.7% (χ 2 =2.83, P>0.05) for patients with T 3 disease, 92.2% and 83.1%(χ 2 = 6.30, P 4 , and 93.1% and 97.5% (χ 2 = 4.69, P = 0.030) when chemotherapy was concurrently administered.The 2-year LCR was 98%, 96% and 93% (χ 2 = 2.20, P = 0.531) for patients with treatment interruption before, within and after the 3rd week of IMRT, The Cox regression analysis found that OTT was an independent prognostic factor for LCR in T 4 disease.The Linear regression showed that the 2-year LCR was decreased by 2.7% per day of delay. Between the groups with OTT≤45 days and OTT >45 days, the 2-year estimated disease-specific survival (DSS), distant metastasis-free survival (DMFS) and overall survival (OS) were 84.1% vs.78.7% (χ 2 = 0.02, P = 0.881), 87.0% vs.86.1% (χ 2 = 0.85, P = 0.358), and 91.7% vs. 92.2% (χ 2 = 0.06, P = 0.806), respectively.The further stratified analysis found that the DSS, DMFS and OS were similar between the two groups in T 3 (83.7% vs. 83.2%, χ 2 =0.07, P=0.798; 86.6% vs. 85.7%, χ 2 =0.02, P = 0.898 ; and 93.7% vs. 94.8%, χ 2 =0.03, P=0.862) and T 4 disease (81.4% vs. 72.3%, χ 2 = 0.16, P = 0.687; 82.6% vs. 86.9%, χ 2 = 1.78, P =0.182; and 88.3% vs. 87.5%, χ 2 =0.60, P =0.438).In multivariate analysis, T-stage and N-stage were the independent prognostic factors for both DFS and OS, and N-stage was the independent prognostic

    In a pilot study the role of intraoperative radiotherapy in the treatment of locally advanced or recurrent renal cell cacinomas was analysed. From January 1992 to July 1994 11 patients with a primary (n=3) or recurrent renal cell carcinoma had IORT. One patient had complete resection and in 3 respectively 7 patients microscopically or macroscopically residual disease was left. Using 6 to 10 MeV, a single dose of 15 to 20 Gy was delivered to the fossa renalis and the corresponding paraaortic area. Based on three-dimensional treatment planning, additional external beam radiotherapy was given 3 to 4 weeks later (40 Gy, 2 Gy SD, 23 mV). After a mean follow-up of 24.3 months 5 patients had died of distant metastases (lung, liver, bone, mediastinum) with a mean survival time of 11.5 months. Mean disease-free interval was 6.4 months. One patient suffered from a second malignancy. Two patients are alive with distant metastases. Local tumor control in the entire group was 100%. The calculated 4-year overall and disease-free survival was 47% and 34%. The postoperative course was affected in 3 patients (abscess n=1, short dehiscence of the abdominal wound n=2). The gastrointestinal toxicity during external beam radiotherapy was low. No IORT-specific late adverse effects were observed.

    The goal of the present work was to compare outcomes of definitive concurrent cisplatin-based chemoradiotherapy (CRT) with cetuximab-based bioradiotherapy (BRT) in locally advanced head-and-neck squamous cell carcinoma (HNSCC). Between 2006 and 2012, 265 patients with locally advanced HNSCC were treated at our institution with CRT (n = 194; 73 %) with three cycles of cisplatin (100 mg/m{sup 2}, every 3 weeks) or BRT (n = 71; 27 %) with weekly cetuximab. Patients receiving BRT had more pre-existing conditions (Charlson index ≥ 2) than the CRT group (p = 0.005). Median follow-up was 29 months. In all, 56 % of patients treated with CRT received the planned three cycles (92 % at least two cycles) and 79 % patients treated with BRT received six cycles or more. The 2-year actuarial overall survival (OS) and progression-free survival (PFS) were 72 % and 61 %, respectively. In the multivariate analysis (MVA), T4 stage, N2-3 stage, smoking status (current smoker as compared with never smoker), and non-oropharyngeal locations predicted for OS, whereas BRT association with OS was of borderline significance (p = 0.054). The 2-year actuarial locoregional control (LRC) and distant control (DC) rates were 73 and 79 %, respectively. CRT was independently associated with an improved LRC (2-year LRC: 76 % for CRT vs. 61 % for BRT) and DC (2-year LRC: 81 % for CRT vs. 68 % for BRT) in comparison with BRT (p < 0.001 and p = 0.01 in the MVA). Subgroup analyses showed that T4 patients benefited significantly from CRT (vs. BRT) in LRC, while T1-3 did not. BRT patients had more G3-4 skin complications (p < 0.001) and CRT patients had higher rates of feeding tube placement (p = 0.006) and G3-4 gastrointestinal toxicities (p < 0.001). This retrospective analysis showed a better LRC in locally advanced HNSCC treated by cisplatin-based CRT than cetuximab-based BRT, and a nonsignificant trend towards an improved OS. (orig.)

    To compare the therapeutic effects, toxic side effects and influence on the immune function in patients treated with TPF [docetaxel (DOC) + cisplatin (DDP) + 5-fluorouracil (5-Fu)] induction chronochemotherapy and conventional chemotherapy for locally advanced nasopharyngeal (NPC). Seventy patients with locally advanced nasopharyngeal carcinoma were treated in our department at their first visit from April 2013 to December 2013. They were divided randomly into two groups: the chronochemotherapy group (38 patients) and conventional chemotherapy group (32 patients). All of the patients were treated with TPF regimen with 2 cycles of induction chemotherapy in a 21-28-days/cycle. The chronochemotherapy group: DOC: 75 mg/m2, i. v. gtt, d1 (03: 30-04: 30); DDP: 75 mg/m2, 10 am-10 pm, c.i.v, d1-d5; 5-Fu: 750 mg·m(-2)·d(-1), 10 pm-10 am, c. i.v., d1-d5, both chemotherapies were administered by intravenous infusion using an automatic electric pump. The conventional chemotherapy group: Both DOC and DDP were administered intravenously at a dose of 75 mg/m2 on d1. 5-Fu was given at a dose of 750 mg/m2 for 24 hours from d1-d5 with continuous infusion in a total of 120 hours. In this procedure, prescribing the conventional intravenous infusion, intensity modulated radiation therapy was used after the induction chemotherapy. The prescribed nasopharyngeal lesion dose (GTVnx) was 69.96 Gy/33 fractions for the T1-T2 nasopharygeal cancer, while 73.92 Gy/33 fractions nasopharynx lesion dose (GTVnx) for the T3-T4 nasopharyngeal cancer. The planning target volume (PTV) of positive lymph node (PTVnd) dose was 69.96 Gy/33 fractions. Concurrent chemoradiotherapy: cisplatin 100 mg/m2, i. v. gtt. d1-d2, and there were two cycles in total and 21 days each cycle. Sixty-six patients were evaluable for the response assessment. There were 36 patients in the chronochemotherapy group and 30 patients in the conventional chemotherapy group. After the induction chemotherapy, no CR case was found in

    To explore the role of Major Vault Protein (MVP) in oral cavity squamous cell carcinoma patients. 131 consecutive patients suffering from oral cavity squamous cell carcinoma were included in the study. In the whole series, the mean follow-up for survivors was 123.11 ± 40.36 months. Patients in tumour stages I and II were referred to surgery; patients in stage III-IV to postoperative radiotherapy (mean dose = 62.13 ± 7.74 Gy in 1.8-2 Gy/fraction). MVP expression was studied by immunohistochemistry in paraffin-embedded tumour tissue. MVP expression was positive in 112 patients (85.5%) and no relation was found with clinic pathological variables. MVP overexpression (those tumours with moderate or strong expression of the protein) was related to insulin-like growth factor receptor-1 (IGF-1R) expression (P = 0.014). Tumour stage of the disease was the most important prognostic factor related to survival. Tumours overexpressing MVP and IGF-1R were strongly related to poor disease-free survival (P = 0.008, Exp(B) = 2.730, CI95% (1.302-5.724)) and cause-specific survival (P = 0.014, Exp(B) = 2.570, CI95% (1.215-5.437)) in patients achieving tumour stages III-IV, in multivariate analysis. MVP and IGF-1R expression were related in oral squamous cell carcinoma and conferred reduced long-term survival in patients suffering from advanced stages of the disease.

    To compare the usefulness of mammography and clinical examination in the evaluation of residual cancer of locally-advanced breast carcinoma treated with neoadjuvant chemotherapy. Among 67 patients with locally advanced breast carcinoma who were treated with neoadjuvant chemotherapy, 18, aged 35-67 (mean, 48) years, underwent mammography before and after this therapy. The 18 sets of mammographs were analyzed retrospectively and compared with the results of clinical examination based on histologic diagnosis. On histologic examinations, 16 of 18 patients (89%) were found to have residual cancer, but in one of these 16, mammography did not show this same result. On mammography, residual cancer was found in 16 patients, but in one of this group, histologic examination did not reveal the same finding. Clinically, a complete response was shown by four patients, and a partial response by 11 ; three showed no response. On histolgogic examination, three of the four patients with complete clinical response were found to have residual cancer. Post-treatment mammographic findings showed that 11 patients had measurable mass ; all of these had residual cancer (positive predictive value : 100%). However, five of seven patients in whom no measurable mass was evident also had residual cancer. Seven of 8 patients in whom microcalcifications were seen on mammography were found to have residual cancer (positive predictive value : 88%). The sensitivity of mammography in predicting residual cancer was greater than that of clinical examination (94% vs 81%), even when microscopic residual cancer was considered as a complete response (92% vs 77%). The specificity of mammography was the same as that of clinical examination(50% vs 50%, 20% vs 20%). In evaluating residual cancer of locally-advanced breast carcinoma after neoadjuvant chemotheragy, mammography is more accurate and informative than clincal examination. In predicting residual cancer, however, it is not accurate enough to replace

    This study evaluated the efficacy and toxicity of chemoradiotherapy using docetaxel (DOC), cisplatin (CDDP) and 5-fluorouracil (5-FU) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). Nineteen patients with previously untreated stage III-IV SCCHN were entered onto this trial. Patients received two cycles of chemotherapy with TPF. Radiation was targeted to begin on the first day of chemotherapy, day 1. The total radiation dose was between 63.0 and 74.0 Gy. At least three patients were examined at each dose level before advancing to the next level. The maximum-tolerated dose (MTD) of this regimen was DOC 60, CDDP 60 and 5-FU 600 mg/m 2 /day. The main toxicities were mucositis, leukocytopenia, neutropenia, anemia, liver dysfunction and renal dysfunction. The overall response rate was 100%, including 84% complete responses (CR). The high complete response rate justifies further evaluation of this chemoradiotherapy modality in advanced SCCHN patients. (author)

    Primary treatment of carcinoma of the oro-/hypopharynx or larynx may consist of combined platinum-containing chemoradiotherapy. In order to improve clinical outcome (i.e. local control/overall survival), combined therapy is intensified by the addition of the EGFR inhibitor cetuximab (Erbitux ® ). Radiation therapy (RT) is carried out as intensity-modulated RT (IMRT) to avoid higher grade acute and late toxicity by sparing of surrounding normal tissues. The REACH study is a prospective phase II study combining chemoradiotherapy with carboplatin/5-Fluorouracil (5-FU) and the monoclonal epidermal growth factor-receptor (EGFR) antibody cetuximab (Erbitux ® ) as intensity-modulated radiation therapy in patients with locally advanced squamous-cell carcinomas of oropharynx, hypopharynx or larynx. Patients receive weekly chemotherapy infusions in the 1 st and 5 th week of RT. Additionally, cetuximab is administered weekly throughout the treatment course. IMRT is delivered as in a classical concomitant boost concept (bid from fraction 16) to a total dose of 69,9 Gy. Primary endpoint of the trial is local-regional control (LRC). Disease-free survival, progression-free survival, overall survival, toxicity, proteomic and genomic analyses are secondary endpoints. The aim is to explore the efficacy as well as the safety and feasibility of this combined radioimmunchemotherapy in order to improve the outcome of patients with advanced head and neck cancer.

    Introduction A 5-flurouracil, Adriamycin, Cyclophosphamide (FAC) and Adriamycin, Paclitaxel (AT) are two popular chemotherapeutic regimens for treatment of breast carcinoma. The most time tested and popular regimen is FAC. It is extensively studied for efficacy and toxicity. But data regarding toxicity profile and efficacy of AT regimen is sparse. Aim To study the toxicity profile, severity of toxicities and clinical response rate of FAC and AT regimens in patients with locally advanced breast carcinoma. Materials and Methods A prospective observational study with 50 patients in each treatment arm. Study duration was 12 months from November 2012 to October 2013. Consecutive patients with locally advanced breast carcinoma receiving treatment with either FAC or AT regimen, satisfying inclusion criteria were enrolled into the study after getting informed written consent. Prior to initiation of treatment detailed medical history was taken from all patients. General clinical examination, examination of organ systems and local examination of breast lump were done. After each cycle of chemotherapy and after completion of treatment patients were interviewed and examined for clinical response and toxicities. Toxicities were graded with WHO toxicity grading criteria. All data were entered in a structured proforma. At least 50% reduction in tumour size was taken as adequate clinical response. Statistical Analysis Data was analysed using Chi-square test with help of Excel 2007 and SPSS-16 statistical software. Results Different pattern of toxicities were seen with FAC and AT regimens. Anaemia, thrombocytopenia, stomatitis, hyperpigmentation, photosensitivity and diarrhoea were more common with patients receiving FAC regimen. Leucopenia, peripheral neuropathy, myalgia, arthralgia, vomiting and injection site reactions were more common in AT regimen. Both FAC and AT regimens gave 100% clinical response. Conclusion FAC and AT regimens are equally efficacious but have different

    Purpose: To prove the superiority of concurrent radiochemotherapy (RTCT) over radiotherapy (RT) alone in locally advanced cervical carcinoma. Patients and Methods: In this randomized monocentric phase III study, 566 patients with squamous cell carcinoma of the cervix were included: 284 in arm A (RT) and 282 in arm B (concurrent RTCT with cisplatin 20 mg/m{sup 2} x 5 days). 238 patients (42%) were in stage IIB, 209 (37%) in stage IIIA, and 119 (21%) in stage IIIB. The median follow-up was 62.8 months. RT to the pelvis was delivered to a dose of 46 Gy/23 fractions. A cervical boost was given using the X-ray arch technique or high-dose-rate intracavitary brachytherapy at a dose of 10 Gy. Thereafter, patients were evaluated: those with good response optionally underwent surgery and the others continued RT until 64 Gy/pelvis (with or without CT according to randomization) and 14 Gy/central tumor volume. Results: The 5-year survival rate was statistically significantly superior in the concurrent RTCT group (74%) versus the RT group (64%; p < 0.05). In patients undergoing surgery after RT or RTCT, superior results were obtained, compared to the nonoperated patients: 5-year survival rate 86% versus 53% (p < 0.01). 192 failures were recorded: 109 (38%) after RT alone versus 83 (29%) after concurrent RTCT (p < 0.01). Conclusion: The results of this study prove the obvious superiority of concurrent RTCT with 5-day cisplatin compared to RT alone in patients with locally advanced cervical carcinoma, regarding local control (78% vs. 67%) and 5-year survival rates (74% vs. 64%).

    The evaluation of 5-year results obtained through 2 radiochemotherapy (RCT) regimens: cisplatin (CDDP), 20 mg/m × 5 days every 21 days; and CDDP, 40 mg/m per week in locally advanced cervical carcinoma. In this single-institution prospective randomized phase 3 study, 326 patients with stage IIB to IIIB squamous cell cervical carcinoma treated from March 2003 to March 2005 were included. One hundred sixty patients (49%) had stage IIB cervical carcinoma, 103 patients (31.5%) had stage IIIA cervical carcinoma, and 63 patients (19.5%) had stage IIIB cervical carcinoma. The patients were randomly assigned to 2 therapeutic arms: 164 patients in arm A (5 days) concurrent RCT with CDDP, 20 mg/m per day, days 1 to 5 every 21 days; and 162 patients in arm B (weekly), concurrent RCT with CDDP, 40 mg/m per day weekly. All patients were treated with external beam radiotherapy on the abdominopelvic region using 15-MV x-rays and a cervical boost using the x-rays arch technique or medium-dose-rate intracavitary brachytherapy. The 5-year survival rate obtained through the 2 RCT regimens are not statistically different, even if a tendency of superiority can be observed in the 5-day arm as far as overall survival (78% in arm A vs 72% in arm B; p = 0.14) and disease-free survival (73% in arm A and 69% in arm B; p = 0.09) are concerned. Five-year local relapse-free survival was significantly superior in the 5-day CDDP arm (87%) in comparison with the weekly CDDP arm (77%); p < 0.01. In the 5-day arm, local relapse rate was twice lower, 21/164 (13%), compared with the weekly arm, 40/162 (25%); p < 0.01). Distance failures were identical in the 2 therapeutic groups: 22/164 (13%) and 21/162 (13%), respectively, which shows the superiority of arm A regarding local control. The results of our study demonstrate that RCT with cisplatin, 20 mg/m × 5 days every 21 days, is superior regarding local efficacy and is less toxic compared with the weekly chemotherapy regimen.

    From 1974 to 1984, 442 consecutive patients with carcinoma of the uterine cervix (FIGO IIB: 139, IIIA: 10, IIIB: 221, IVA: 72) were referred for combined intracavitary (IRT) and external radiotherapy (ERT). To improve local control and reduce late rectosigmoid morbidity the treatment strategy was changed from continuous (CRT) to split-course radiotherapy (SCRT) in 1978. Stage by stage the 5-year actuarial estimates of survival, local control, and late morbidity did not differ in relation to strategy. In the patients with tumours larger than 8 cm, the SCRT involved an increased dose in point B, a reduced dose in point A from the IRT, a lower total dose in point A, and a 34 day's prolongation of the total treatment time (TTT). The resulting 5-year actuarial local control rates were significantly lower compared with those after CRT. No difference of late severe morbidity was found except in IVA patients. In the patients with tumours between 4 and 8 cm, the SCRT involved a reduced dose in point A from the IRT, an increased total dose in point A and B, and a 50 day's prolongation of the TTT. In patients with stage IIB, the 5-year actuarial central local control rate was lower (p=0.06), and the 5-year estimate of late severe morbidity significantly higher after SCRT compared with CRT. It is concluded that the increase of the dose in point B in the SCRT was insufficient to prevent the deleterious effect on local tumour control of either the lower dose from IRT in point A, or the prolonged TTT. The increase of the total dose in the SCRT may explain why the late morbidity was not reduced, and may suggest that the TTT is of no significant importance for the risk of late normal tissue damage.

    This is the first study that aimed to determine the efficacy and safety of concurrent chemoradiation with weekly cisplatin ± celecoxib 100 mg twice daily in locally advanced undifferentiated nasopharyngeal carcinoma. Eligible patients had newly diagnosed locally advanced (T3-T4, and/or N2-N3, M0) undifferentiated nasopharyngeal carcinoma, no prior therapy, Karnofsky performance status ≥ 70, and normal organ function. The patients were assigned to receive 7 weeks concurrent chemoradiation (70 Gy) with weekly cisplatin 30 mg/m 2 with either celecoxib 100 mg twice daily, (study group, n = 26) or placebo (control group, n = 27) followed by adjuvant combined chemotherapy with cisplatin 70 mg/m 2 on day 1 plus 5-fluorouracil 750 mg/m 2 /d with 8-h infusion on days 1-3, 3-weekly for 3 cycles. Overall clinical response rate was 100% in both groups. Complete and partial clinical response rates were 64% and 36% in the study group and 44% and 56% in the control group, respectively (P > 0.25). The addition of celecoxib to concurrent chemoradiation was associated with improved 2-year locoregional control rate from 84% to 100% (P = 0.039). The addition of celecoxib 100 mg twice daily to concurrent chemoradiation improved 2-year locoregional control rate.

    This is a retrospective study of patients with advanced biliary tract carcinoma (BTC), who were treated with different regimens of chemotherapy. We studied patients with advanced BTC registered at the Department of Oncology at the Fundeni Clinical Institute between 2004 and 2008. The following data were analyzed: rate of response, progression free survival (PFS) to first and second line of chemotherapy, overall survival (OS) and drug toxicity. Ninety-six patients were eligible having either advanced intra or extrahepatic cholangiocarcinoma, or gallbladder cancer with no prior chemotherapy. Out of 96 patients, 57 (59.4%) received fluoropyrimidines (FP)+cisplatin and 39 (40.6%) gemcitabine (Gem)+/-cisplatin. The median PFS for FP+cisplatin was 5.9 months (95%CI 5-6.9) and for Gem+/-cisplatin 6.3 months (95%CI 5.4-7.1), p=0.661. Median OS for FP+cisplatin was 10.3 months (95%CI 7.5-13.1) and for Gem+/-cisplatin 9.1 months (95%CI 7.0-11.2), p=0.098. On disease progression, 46 patients received second line CT (Gem or FP+/-platinum compounds). Median OS for patients with FP based first line and Gem+/-cisplatin in second line was 19 months (95%CI 8.9-29) higher than for the reverse sequence: 13.2 months (95%CI 12-14.4), but not statistically significant (p=0.830). All patients were evaluated for toxicities. Most patients (75.5%) reported at least one adverse event. Our results through direct comparison of FP+cisplatin with Gem+/-cisplatin as first line treatment did not show any statistical differences in terms of rate of response, PFS and OS. However, our study showed that FP+cisplatin as first line and Gem based second line therapy gave a better OS rate.

    The prognostic significance of pathological response of primary tumor and metastatic axillary lymph nodes after neoadjuvant chemotherapy was assessed in patients with noninflammatory locally advanced breast carcinoma. Between January 1989 and April 1995, 148 consecutive patients with locally advanced breast carcinoma participated in the study. Of these, 140 fully evaluable patients (67, stage IIIA; 73, stage IIIB) were treated with three courses of 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC), followed by modified radical mastectomy when technically feasible or definitive radiation therapy. The median age was 53 years (range, 26 to 75 years); 55% of patients were postmenopausal. Objective response was recorded in 99 of 140 patients (71%; 95% confidence interval, 63% to 79%). Complete response occurred in 11 patients (8%), and partial response occurred in 88 patients (63%). No change was recorded in 37 patients (26%), and progressive disease occurred in 4 patients (3%). One hundred and thirty-six patients underwent the planned surgery. Maximal pathological response of the primary tumor (in situ carcinoma or minimal microscopic residual tumor) was observed in 24 (18%); 112 patients (82%) presented minimal pathological response of the primary tumor (gross residual tumor). The number of metastatic axillary nodes after neoadjuvant chemotherapy was as follows: N0, 39 patients (29%); N1-N3, 35 patients (26%); > N3, 62 patients (45%). Considering the initial TNM status, 75% of the patients had decreases in tumor compartment after neoadjuvant chemotherapy. Also, 31% and 23% of patients with clinical N1 and N2, respectively, showed uninvolved axillary lymph nodes. A significant correlation was noted between pathological response of primary tumor and the number of metastatic axillary lymph nodes. Median disease-free survival was 34 months, whereas median overall survival was 66 months. Pathological responses of both primary tumor and metastatic axillary lymph nodes

    55 patients with advanced cutaneous squamous cell carcinoma (CSCC) of the trunk and extremities were studied. A Tissue Micro array was constructed using immunohistochemistry to quantify expression of the HER family, E-cadherins, and podoplanin. Clinical and histopathological factors related to lymph node metastasis and prognosis were also established. Primary tumor positivity was 25.5% for EGFR, 87.3% for HER-3, and 48.1% for HER-4. Metastases were positive for EGFR in 41.7%, for HER-3 in 83.3%, and HER-4 in 43.5%. HER-2 was negative in all samples. Membrane E-cadherin and cytoplasmic E-cadherin were positive in 47.3% and 30.2% of primary tumors and 45.5% and 27.3% of metastases, respectively. Podoplanin was positive in 41.8% of primary tumors and 41.7% of metastases. Intratumoral lymphocytic infiltrate was associated with lymph node metastasis. Patients with T3 tumors had better cancer-specific survival (CSS) than those with T4 tumors; patients with no lymph node involvement had better CSS than patients with N1 tumors. Undifferentiated tumors and hyper expression of podoplanin were negative prognostic indicators on multivariate analysis

    Sorafenib and transarterial (90) Y-radioembolization (TARE) are possible treatments for Barcelona Clinic Liver Cancer (BCLC) intermediate-advanced stage hepatocellular carcinoma (HCC). No study directly comparing sorafenib and TARE is currently available. This single-centre retrospective study compares the outcomes achieved with sorafenib and TARE in HCC patients potentially amenable to either therapy. Seventy-four sorafenib (71 ± 10 years, male 87%, BCLC B/C 53%/47%) and 63 TARE HCC patients (66 ± 9 years, male 79%, BCLC B/C 41%/59%) were included based on the following criteria: Child-Pugh class A/B, performance status ≤1, HCC unfit for other effective therapies, no metastases and no previous systemic chemotherapy. Median overall survivals of the two groups were comparable, being 14.4 months (95% CI: 4.3-24.5) in sorafenib and 13.2 months (95% CI: 6.1-20.2) in TARE patients, with 1-, 2- and 3-year survival rates of 52.1%, 29.3% and 14.7% vs 51.8%, 27.8% and 21.6% respectively. Two TARE patients underwent liver transplantation after successful down-staging. To minimize the impact of confounding factors on survival analysis, propensity model matched 32 patients of each group for median age, tumour gross pathology and the independent prognostic factors (portal vein thrombosis, performance status, Model for End Liver Disease). Even after matching, the median survival did not differ between sorafenib (13.1 months; 95% CI: 1.2-25.9) and TARE patients (11.2 months; 95% CI: 6.7-15.7), with comparable 1-, 2- and 3-year survival rates. In cirrhotic patients with intermediate-advanced or not-otherwise-treatable HCC, sorafenib and TARE provide similar survivals. Down-staging allowing liver transplantation only occurred after TARE. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Patients with a rising serum carcinoembryonic antigen level and no clinical or roentgenographic evidence of recurrent or metastatic cancer present a treatment dilemma. Eleven such patients, 10 with a previously treated colorectal carcinoma and 1 with a previously treated breast carcinoma, received an injection of the anticarcinoembryonic antigen monoclonal antibody ZCE-025 labeled with the radioisotope indium 111. Nuclear scintigraphy was performed on days 3 and 5 through 7 to detect potential sites of tumor recurrence. The monoclonal antibody scan accurately predicted the presence or absence of occult malignancy in 7 (64%) patients. Second-look laparotomy confirmed the monoclonal antibody scan results in the patients with colorectal cancer, and magnetic resonance imaging confirmed metastatic breast cancer. This study demonstrates that In-ZCE-025 can localize occult carcinoma and may assist the surgeon in facilitating the operative exploration. In-ZCE-025 assisted in the initiation of adjuvant therapy for the patient with breast cancer

    The purpose of this work is to report the long-term outcomes of three-dimensional conformal radio(chemo)therapy in the curative management of esophageal squamous cell carcinoma (ESCC). A retrospective analysis of patients treated with radio(chemo)therapy between 1988 and 2011 at Klinikum rechts der Isar, Technische Universitaet Muenchen was performed. In all, 168 patients received radio(chemo)therapy for ESCC in curative intention. The median follow-up time was 91 months (range 1-212 months). There were 128 men and 40 women with a median age of 63 years. Selection criteria for radio(chemo)therapy were unfit for surgery and/or unresectable primary tumor (n = 146, 87 %) or patients' choice (n = 22, 13 %). The majority of the patients received a combination of cisplatin and 5-fluorouracil chemotherapy with 54 Gy in 30 fractions of radiotherapy. The median overall survival (OS) was 20 months (95 % confidence interval 17-23 months). The OS at 2 and 5 years for the whole cohort was 41 ± 4 % and 22 ± 3 %, respectively. Forty patients (24 %) suffered an in-field recurrence. The most common acute nonhematologic toxicity >grade 2 was dysphagia in 35 % of the patients. Acute hematologic toxicity > grade 2 was recorded in 14 % of the patients. There was no grade 5 toxicity observed during the study. Poor ECOG performance status (0-1 vs. 2-3, HR = 1.70, p = 0.002) and weight loss ≥ 10 % before the start of therapy (HR = 1.99, p = 0.001) were among the factors significantly associated with poor OS in multivariate analysis. Three-dimensional conformal definitive radio(chemo)therapy is well tolerated and leads to long-term survival in more than 20 % of patients with advanced disease and/or contraindication to surgery. However, 24 % in-field recurrence remains a major concern. Prospective trials are warranted to assess if a well-tailored conformal radiochemotherapy can improve the local control and obviate the need for surgical resection in patients with good general

    The aim of this randomised trial was to investigate the effect of induction chemotherapy before radiotherapy on survival in 302 patients with non-resectable squamous cell carcinoma of the lung. Radiotherapy, 56 Gy to the chest, was given to 154 patients and combined treatment, with chemotherapy preceding the radiotherapy, to 148 patients. Chemotherapy consisted of three courses of cisplatin (120 mg/m 2 ) and etoposide (100 mg/m 2 i.v. for 3 days) administered every fourth week. Median survival was 10.5 months in the radiotherapy arm and 11 months in the combined treatment arm. The 2-year survival rate was 17% in the radiotherapy arm and 21% in the combined treatment arm. Addition of chemotherapy seemed to significantly improve survival, according to the Cox multivariate analysis (P = 0.04), but as only a trend according to life-table analysis (P = 0.11). Chemotherapy also accomplished a trend towards improved local control (P 0.08) and towards decreased metastatic disease (P = 0.10). 2 patients in the combined treatment arm, but none in the radiotherapy ar, died from toxicity. The conclusion was that the value of the chemotherapy used in this study was very modest, but the results strongly support further research for more efficient drugs and combinations. (author)

    Background and purpose: The aim of this study was to prospectively assess the quality of life (QOL) of patients treated by concomitant chemo radiation for locally advanced anal canal carcinoma. Materials and methods: We report on a subgroup of 119 patients enrolled in a 306-patient therapeutic intensification prospective trial (ACCORD 03). This trial evaluated the impact on colostomy-free survival of induction chemotherapy and/or high dose radiotherapy (factorial design 2 * 2 treatment arms). QOL was assessed both before and 2 months after treatment using the EORTC QLQ-C30 questionnaire as well as a questionnaire relating to anal sphincter conservative treatment (AS-CT). Results: Compared to pre-treatment scores, patients reported significant improvement in their emotional function (+8.4 points p = 0.002), global health status (+5.9 points p = 0.0007), as well as a decrease in insomnia (-13.8 points p < 0.0001), constipation (-12.0 points p < 0.0001), appetite loss (-10.3 points p < 0.0001) and pain (-9.6 points p = 0.0002). The AS-CT degree of satisfaction with intestinal functions score was increased (+11.2 points p < 0.0001). Conclusion: This is the first prospective study comparing QOL of patients with advanced anal canal carcinoma, before and 2 months after conservative treatment. Two months after treatment, QOL was improved. Induction chemotherapy and/or high dose radiotherapy did not provide a negative impact on QOL

    To evaluate the utility of a standardized qualitative scoring system for treatment response assessment at 18F-FDG PET-CT in patients undergoing chemoradiotherapy for locally advanced cervical carcinoma and correlate this with subsequent patient outcome. Ninety-six consecutive patients with locally advanced cervical carcinoma treated with radical chemoradiotherapy (CRT) in a single centre between 2011 and 2014 underwent 18F-FDG PET-CT approximately 3 months post-treatment. Tumour metabolic response was assessed qualitatively using a 5-point scale ranging from background level activity only through to progressive metabolic disease. Clinical and radiological (MRI pelvis) follow-up was performed in all patients. Progression-free (PFS) and overall survival (OS) was calculated using the Kaplan-Meier method (Mantel-Cox log-rank) and correlated with qualitative score using Chi-squared test. Forty patients (41.7 %) demonstrated complete metabolic response (CMR) on post-treatment PET-CT (Score 1/2) with 38 patients (95.0 %) remaining disease free after a minimum follow-up period of 18 months. Twenty-four patients (25.0 %) had indeterminate residual uptake (ID, Score 3) at primary or nodal sites after treatment, of these eight patients (33.3 %) relapsed on follow-up, including all patients with residual nodal uptake (n = 4). 11 of 17 patients (64.7 %) with significant residual uptake (partial metabolic response, PMR, Score 4) subsequently relapsed. In 15 patients (15.6 %) PET-CT demonstrated progressive disease (PD, Score 5) following treatment. Kaplan-Meier analysis showed a highly statistically significant difference in PFS and OS between patients with CMR, indeterminate uptake, PMR and PD (Log-rank, P < 0.0001). Chi-squared test demonstrated a highly statistically significant association between increasing qualitative score and risk of recurrence or death (P < 0.001).

Methods: This study retrospectively evaluated 202 patients with locally advanced ESCC treated at Shandong Cancer Hospital between January 2009 and December 2013. All the patients initially received dCRT, including platinum and paclitaxel or 5-fluorouracil, with concurrent 1.8 or 2 Gy/fraction radiation (total dose, 54–60 Gy. The patient population was divided into two treatment groups: 105 patients who received the cisplatinum/paclitaxel regimen were allocated to group A, and 97 patients who received the cisplatinum/5-fluorouracil regimen were allocated to group B. We compared the progression-free survival (PFS and overall survival (OS by various clinical variables, including prior treatment characteristics, major toxicities (mainly in grade 3 and 4 hematological, and response to dCRT. We used the receiver operating curve analysis to determine the optimal cutoff value of clinical stage and radiation dose. The Kaplan–Meier method was used for survival comparison and Cox regression for multivariate analysis. Results: Median PFS and OS in group A were significantly better compared with group B (median PFS, 15.9 versus 13.0 months, P=0.016 and median OS, 33.9 versus 23.1 months, P=0.014, respectively. The 1- and 2-year survival rates of the two groups were 82.9% versus 76.3%, and 61.9% versus 47.6%, respectively. The complete response and response rate

    The purpose of this study was to evaluate long-term outcomes after induction chemotherapy followed by "risk-based" local therapy for locally-advanced squamous cell carcinoma of the head and neck (SCCHN). Forty-seven patients (stage IV; ≥N2b) were enrolled in a phase II trial. Baseline and 24-month functional measures included modified barium swallow (MBS) studies, oropharyngeal swallow efficiency (OPSE), and the MD Anderson Dysphagia Inventory (MDADI). Functional status was assessed at 5 years. Five-year overall survival (OS) was 89% (95% confidence interval [CI], 81% to 99%). A nonsignificant 13% average reduction in swallowing efficiency (OPSE) was observed at 24 months relative to baseline (p = .191). MDADI scores approximated baseline at 24 months. Among 42 long-term survivors (median, 5.9 years), 3 patients (7.1%) had chronic dysphagia. The rate of final gastrostomy dependence was 4.8% (2 of 42). Sequential chemoradiotherapy achieved favorable outcomes among patients with locally advanced SCCHN, mainly of oropharyngeal origin. MBS and MDADI scores found modest swallowing deterioration at 2 years, and chronic aspiration was uncommon in long-term survivors. Copyright © 2013 Wiley Periodicals, Inc.

    To review radiation fractionation and chemotherapy trials for patients undergoing organ preservation therapy for locally advanced head and neck squamous cell carcinoma. Radiation therapy fractionation and chemotherapy trial results as well as historical evidence are systematically reviewed. Trial results, which involve nearly 30,000 patients, have been interpreted, compared, and presented in a structured manner to demonstrate the changing approaches in treatment over the years from the 1960s to the present. The review includes data from the split-course radiation therapy era, meta-analyses of chemotherapy and radiation therapy fractionation trials, cetuximab trials, "triple-drug trials," and modern trials of induction chemotherapy followed by concomitant chemotherapy and radiation therapy. This summary will be useful to clinicians making treatment decisions today and to investigators designing trials in the future. Copyright © 2015 American Society for Radiation Oncology.

    Purpose: To compare volumetric modulated arc radiotherapy (VMAT) technique with fixed-gantry intensity-modulated radiotherapy (IMRT) technique for locally advanced laryngeal carcinoma. Methods: CT datasets of eleven patients were included. Dual-arc VMAT and 7-field IMRT plans, which were created based on the Eclipse treatment planning system, were compared in terms of dose-volume parameters, conformity index (CI) and homogeneity index (HI) of planning target volume (PTV), as well as organ-at-risk (OAR) sparing, planning time, monitor units (MUs) and delivery time. Results: Compared with the IMRT plans, the VMAT plans provided lower D2% and better CI/HI for the high-risk PTV (PTV1), and provided better CI and comparable HI for the low-risk PTV (PTV2). Concerning the OAR sparing, the VMAT plans demonstrated significantly lower Dmax of the spinal cord (planning OAR volume, PRV) and brainstem (PRV), as well as lower Dmean and V30Gy of the right parotid. No significant differences were observed between the two plans concerning the doses delivered to the thyroid, carotid, oral cavity and left parotid. Moreover, the VMAT planning (147 ± 18 min) consumed 213% more time than the IMRT planning (48 ± 10 min). The MUs of the VMAT plans (556 ± 52) were 64% less than those of the IMRT plans (1684 ± 409), and the average delivery time (2.1 ± 0.1 min) was 66% less than that of the IMRT plans (6.3 ± 0.7 min). Conclusion: Compared with the IMRT technique, the VMAT technique can achieve superior target dose distribution and better sparing of the spinal cord, brainstem and right parotid, with less MUs and less delivery time. It is recommended for the radiotherapy of locally advanced laryngeal carcinoma.

    Background: Neither surgical advances nor those in therapeutic radiology have been able to significantly reduce the mortality related to esophageal carcinomas. The results of combining: first surgery, then radiation therapy, which have been dissatisfactory for decades, encourage therapeutic concepts involving a variety of modalities. Patients and Methods: For 50 patients with unresectable locally advanced esophageal carcinomas, a palliative concurrent chemotherapy and radiation therapy was carried out according to the ''intent to treat'' principle. The aim was a minimal dose of 40 Gy. The concurrent chemotherapy was carried out using cisplatin/5-FU during the 1st and 4th weeks of radiation therapy. In the case of partial or complete remission, the chemotherapy was to be continued as maintenance therapy with a maximum of four cycles. In the case of no change or minor response, instead of maintenance chemotherapy, the dose of local radiation was to be increased by means of brachytherapy. Results: The median survival rate for the entire population under study was 8.7 months. The survival rates of 1, 2, 3, 4, and 5 years were, respectively, 38%, 20.5%, 13.7%, 6.8%, and 6.8%. The remission rates were as follows: NC: 14 patients (28%), PR: 32 patients (64%), CR: 4 patients (8%). 17 patients (34%) tolerated the full concurrent chemotherapy; only twelve patients (24%) tolerated supportive chemotherapy. The following factors exhibited a significant correlation to survival: the intensity of the chemotherapy, the Karnofsky index, the age of the patients, and the improvement of oral food intake. Conclusions: The concurrent chemotherapy was toxic and the benefit to the patients questionable. At best, meta-analyses of randomized studies along the lines of ''evidence-based medicine'' demonstrate for concurrent chemotherapy and radiation therapy an improvement of 2-year survival rates, but with these also involving a high level of toxicity. Due to the heterogeneous data available

    Currently there are no molecular markers able to predict clinical outcome in locally advanced head and neck squamous cell carcinoma (HNSCC). In a previous microarray study, RAB25 was identified as a potential prognostic marker. The aim of this study was to analyze the association between RAB25 expression and clinical outcome in patients with locally advanced HNSCC treated with standard therapy. In a retrospective immunohistochemical study (n = 97), we observed that RAB25-negative tumors had lower survival (log-rank, P = 0.01) than patients bearing positive tumors. In an independent prospective mRNA study (n = 117), low RAB25 mRNA expression was associated with poor prognosis. Using classification and regression tree analysis (CART) we established two groups of patients according to their RAB25 mRNA level and their risk of death. Low mRNA level was associated with poor local recurrence-free (log-rank, P = 0.005), progression-free (log-rank, P = 0.002) and cancer-specific (log-rank, P < 0.001) survival. Multivariate Cox model analysis showed that low expression of RAB25 was an independent poor prognostic factor for survival (hazard ratio: 3.84, 95% confidence interval: 1.93–7.62, P < 0.001). Patients whose tumors showed high RAB25 expression had a low probability of death after treatment. We also found lower RAB25 expression in tumors than in normal tissue (Mann–Whitney U, P < 0.001). Moreover, overexpression of RAB25 in the UM-SCC-74B HNSCC cell line increased cisplatin sensitivity, and reduced cell migration and invasion. Our findings support a tumor suppressor role for RAB25 in HNSCC and its potential use to identify locally advanced patients with a high probability of survival after genotoxic treatment

    Background and purpose: This multicenter phase II trial investigated cetuximab combined with chemoradiotherapy in patients with esophageal squamous cell carcinoma (ESCC). Material and methods: Eligible patients with non-resectable, locally-advanced ESCC received cetuximab 400 mg/m 2 loading dose on day 1; and on day 1 of the 2nd–7th weeks: cetuximab 250 mg/m 2 , paclitaxel 45 mg/m 2 , and cisplatin 20 mg/m 2 , concurrent with 59.4 Gy/33 fractions of radiation therapy. Primary endpoint was clinical response rate. Secondary endpoints included overall survival (OS), progression-free survival (PFS), safety, and KRAS status. Results: Of 55 patients enrolled, 45 completed therapy. Forty-four patients had a clinical response: 29 complete response and 15 partial response. One-year PFS and OS of 45 evaluable patients were 84.23% and 93.33%, respectively, and 2-year PFS and OS were 74.87% and 80.00%, respectively. Non-hematologic adverse events were generally grade 1 or 2; primarily rash (92.7%), mucositis (45.5%), fatigue (41.8%), and nausea (38.2%). Grade 3 hematologic adverse events included neutropenia (32.7%) and anemia (1.8%). No KRAS mutations were identified in 50 evaluated samples. Conclusions: Cetuximab can be safely administered with chemoradiotherapy to patients with locally-advanced ESCC and may improve clinical response rate

    The aim of this study was to evaluate the efficacy and toxicity of chemoradiotherapy using docetaxel (DOC), cisplatin (CDDP) and 5-fluorouracil (5-FU) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). Nineteen patients with previously untreated stage III-IV SCCHN were entered onto this trial. Patients received 2 cycles of chemotherapy with TPF. Radiation was targeted to begin on the first day of chemotherapy, day 1. The total radiation dose was between 63.0 and 74.0 Gy At least three patients were examined at each dose level before advancing to the next level. The maximum-tolerated dose (MTD) of this regimen was that DOC 60, CDDP 60 and 5-FU 600 mg/m 2 /day. The main toxicities were mucositis, leukocytopenia, neutropenia, anemia, liver dysfunction and renal dysfunction. The overall response rate was 100%, including 84% complete responses (CR). The high complete response rate justifies further evaluation of this chemoradiotherapy modality in advanced SCCHN patients. (author)

    Cisplatin-based chemotherapy has been widely used in a neoadjuvant as well as adjuvant setting. Furthermore, trimodal approaches including complete transurethral resection of the bladder tumor followed by combined chemotherapy and radiation have generally been performed as bladder preservation therapy. However, none of the protocols have achieved a 5-year survival rate of more than 70%. Additionally, the toxicity of chemotherapy and/or a decreased quality of life due to urinary diversion cannot be ignored, as most patients with bladder cancer are elderly. We therefore newly developed the novel trimodal approach of ''combined therapy using balloon-occluded arterial infusion of anticancer agent and hemodialysis with concurrent radiation, which delivers an extremely high concentration of anticancer agent to the site of a tumor without systemic adverse effects (''Osaka Medical College regimen'' referred to as the OMC regimen). We initially applied the OMC regimen as neoadjuvant chemotherapy for locally advanced bladder cancer. However, since more than 85% of patients with histologically-proven urothelial cancer achieved complete response with no evidence of recurrence after a mean follow-up of 170 (range 21-814) weeks, we have been applying the OMC-regimen as a new approach for bladder sparing therapy. We summarize the advantage and/or disadvantage of chemotherapy in neoadjuvant as well as adjuvant settings, and show the details of our newly developed bladder sparing approach OMC regimen in this review.

    Assessment of nodal response after radiotherapy (RT) for head and neck squamous cell carcinoma is difficult, as both CT and positron emission tomography scanning have limited predictive value for residual disease. We sought to measure changes in nodal volume during RT to determine whether such changes are predictive of nodal disease control. Patients with locally advanced head and neck squamous cell carcinoma treated with 70Gy of radical RT (±chemotherapy or anti-epidermal growth factor receptor (EGFR) antibodies) were eligible. Baseline pre-RT scans and cone-beam CT scans done at the outset of treatment and at weeks 3, 5 and 7 (cone-beam CTs 1, 2, 3 and 4, respectively) were deformably coregistered, and 3D nodal volumes were measured. Thirty-eight eligible patients were identified. The main primary tumour site was oropharyngeal; most patients had stage IVa disease. Twenty-seven patients received concurrent platinum-based chemotherapy, 10 received only an EGFR inhibitor with RT and one received RT alone. Twelve patients had a failure in the neck. After week 1 of treatment, a 4% mean decrease in nodal volume was observed, increasing to 40% at week 7. Platinum-based chemotherapy achieved significantly greater decreases in nodal volume than EGFR inhibitors (44 vs. 25%; P=0.026). Advanced tumour stage predicted neck failure (P=0.002), but nodal volumes did not correlate with neck control. Changes in nodal volume are minimal initially during RT but accelerate during the latter weeks of therapy. This study suggests that chemotherapy achieves a greater decrease in nodal volume than EGFR inhibitors and that nodal changes do not predict disease control in the neck.

    Objective: To investigate the impact of HPV status in patients with locally advanced head and neck squamous cell carcinoma (HNSCC), who received surgery and cisplatin-based postoperative radiochemotherapy. Materials and methods: For 221 patients with locally advanced squamous cell carcinoma of the hypopharynx, oropharynx or oral cavity treated at the 8 partner sites of the German Cancer Consortium, the impact of HPV DNA, p16 overexpression and p53 expression on outcome were retrospectively analysed. The primary endpoint was loco-regional tumour control; secondary endpoints were distant metastases and overall survival. Results: In the total patient population, univariate analyses revealed a significant impact of HPV16 DNA positivity, p16 overexpression, p53 positivity and tumour site on loco-regional tumour control. Multivariate analysis stratified for tumour site showed that positive HPV 16 DNA status correlated with loco-regional tumour control in patients with oropharyngeal carcinoma (p = 0.02) but not in the oral cavity carcinoma group. Multivariate evaluation of the secondary endpoints in the total population revealed a significant association of HPV16 DNA positivity with overall survival (p < 0.01) but not with distant metastases. Conclusions: HPV16 DNA status appears to be a strong prognosticator of loco-regional tumour control after postoperative cisplatin-based radiochemotherapy of locally advanced oropharyngeal carcinoma and is now being explored in a prospective validation trial

    Purpose: To determine the maximum tolerated dose (MTD) of three-dimensional conformal radiation therapy (3DCRT)/intensity-modulated radiation therapy (IMRT) combined with transcatheter arterial chemoembolization for locally advanced hepatocellular carcinoma. Methods and Materials: Patients were assigned to two subgroups based on tumor diameter: Group 1 had tumors <10 cm; Group II had tumors ≥10 cm. Escalation was achieved by increments of 4.0 Gy for each cohort in both groups. Dose-limiting toxicity (DLT) was defined as a grade of ≥3 acute liver or gastrointestinal toxicity or any grade 5 acute toxicity in other organs at risk or radiation-induced liver disease. The dose escalation would be terminated when ≥2 of 8 patients in a cohort experienced DLT. Results: From April 2005 to May 2008, 40 patients were enrolled. In Group I, 11 patients had grade ≤2 acute treatment-related toxicities, and no patient experienced DLT; and in Group II, 10 patients had grade ≤2 acute toxicity, and 1 patient in the group receiving 52 Gy developed radiation-induced liver disease. MTD was 62 Gy for Group I and 52 Gy for Group II. In-field progression-free and local progression-free rates were 100% and 69% at 1 year, and 93% and 44% at 2 years, respectively. Distant metastasis rates were 6% at 1 year and 15% at 2 years. Overall survival rates for 1-year and 2-years were 72% and 62%, respectively. Conclusions: The irradiation dose was safely escalated in hepatocellular carcinoma patients by using 3DCRT/IMRT with an active breathing coordinator. MTD was 62 Gy and 52 Gy for patients with tumor diameters of <10 cm and ≥10 cm, respectively.

    The best way to assess the response to chemoradiotherapy of locally advanced oesophageal carcinomas is not known. We used {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT to evaluate the metabolic response during chemoradiotherapy and tried to correlate this response to survival. Patients with biopsy-proven oesophageal carcinoma underwent FDG PET/CT with evaluation of the standardized uptake value (SUV) before any treatment (SUV1) and during chemoradiotherapy after two cycles of 5-fluorouracil (FU)/cisplatin and 20 Gy (SUV2). Metabolic response was defined as 1-(SUV2/SUV1). Surgery was discussed after 40 Gy and three cycles of chemotherapy. Results of interim PET were not considered for the therapeutic decision. Among 72 patients who underwent a first FDG PET/CT before any treatment, 59 (82 %) could receive the second FDG PET/CT examination. Median survival was 22.2 months with 1-year and 2-year survivals of 70 and 46 %, respectively. Nineteen patients (32 %) underwent surgery. Mean SUV1 and SUV2 were 12.3 {+-} 6.2 and 6 {+-} 4.1, respectively (p < 0.001). Using a cut-off for metabolic response of 50 %, sensitivity and specificity for survival were 0.7 and 0.58. The 2-year overall survival of good responders was 62 % as compared to 27 % for poor metabolic responders. A multivariate analysis was performed, including T and N stages, surgery, histology and metabolic response: only metabolic response was significantly (p = 0.009) associated with 2-year survival. Early evaluation of metabolic response had a great prognostic value and could help identify good responders to chemoradiotherapy. (orig.)

    Purpose: To retrospectively assess the efficacy, toxicity, and prognostic factors of weekly low-dose docetaxel-based chemoradiotherapy for Stage III/IV oropharyngeal or hypopharyngeal carcinoma. Methods and Materials: Between 2001 and 2005, 72 consecutive patients with locally advanced oropharyngeal or hypopharyngeal carcinoma were treated with concurrent chemoradiotherapy (CCR; radiation at 60 Gy plus weekly docetaxel [10 mg/m 2 ]). Thirty of these patients also received neoadjuvant chemotherapy (NAC; docetaxel, cisplatin, and 5-fluorouracil) before concurrent chemoradiotherapy. Survival was calculated according to the Kaplan-Meier method. The prognostic factors were evaluated by univariate and multivariate analyses. Results: The median follow-up was 33 months, with overall survival, disease-free survival, and locoregional control rates at 3 years of 59%, 45%, and 52%, respectively. Thirty-six patients (50%) experienced more than one Grade 3 to 4 acute toxicity. Grade 3 mucositis occurred in 32 patients (44%), Grade 4 laryngeal edema in 1 (1%). Grade ≥3 severe hematologic toxicity was observed in only 2 patients (3%). Grade 3 dysphagia occurred as a late complication in 2 patients (3%). Multivariate analyses identified age, T stage, hemoglobin level, and completion of weekly docetaxel, but not NAC, as significant factors determining disease-free survival. Conclusions: Docetaxel is an active agent used in both concurrent and sequential chemoradiotherapy regimens. Mucositis was the major acute toxicity, but this was well tolerated in most subjects. Anemia was the most significant prognostic factor determining survival. Further studies are warranted to investigate the optimal protocol for integrating docetaxel into first-line chemoradiotherapy regimens, as well as the potential additive impact of NAC.

    Possible deep (more than an inner third of the uterine wall) myometrial invasion and cervical extension of endometrial carcinoma were evaluated prospectively using magnetic resonance (MR) and transabdominal real-time sonography (US) in 20 and 10 patients, respectively. The data obtained from these examinations were compared with hysterosalpingography (HSG) and clinical modalities including hysteroscopy, sounding and histopathologic findings after surgery. The concordance of outlining cervical extension was between MR and hysteroscopy 85 per cent, and between US and hysteroscopy 50 per cent. Deep myometrial tumor invasion was suggested in 4/10 patients by US and in 6/20 by MR, and was confirmed in all but one in each group at histologic examination of the resected uterus. There were no false negative US or MR examinations. Transabdominal US did not prove accurate in defining local endometrial carcinoma (distinguishing between stages I and II), but it may be used as an additional tool in revealing myometrial invasion. MR, however, seems to refine the delineation of uterine tumor growth. (orig.)

    Purpose: To compare survival, tumor control, toxicities, and quality of life of patients with locally advanced nasopharyngeal carcinoma (NPC) treated with induction chemotherapy and concurrent chemo-radiation (CCRT), against CCRT alone. Patients and Methods: Patients were stratified by N stage and randomized to induction GCP (3 cycles of gemcitabine 1000 mg/m{sup 2}, carboplatin area under the concentration-time-curve 2.5, and paclitaxel 70 mg/m{sup 2} given days 1 and 8 every 21 days) followed by CCRT (radiation therapy 69.96 Gy with weekly cisplatin 40 mg/m{sup 2}), or CCRT alone. The accrual of 172 was planned to detect a 15% difference in 5-year overall survival (OS) with a 5% significance level and 80% power. Results: Between September 2004 and August 2012, 180 patients were accrued, and 172 (GCP 86, control 86) were analyzed by intention to treat. There was no significant difference in OS (3-year OS 94.3% [GCP] vs 92.3% [control]; hazard ratio 1.05; 1-sided P=.494]), disease-free survival (hazard ratio 0.77, 95% confidence interval 0.44-1.35, P=.362), and distant metastases–free survival (hazard ratio 0.80, 95% confidence interval 0.38-1.67, P=.547) between the 2 arms. Treatment compliance in the induction phase was good, but the relative dose intensity for concurrent cisplatin was significantly lower in the GCP arm. Overall, the GCP arm had higher rates of grades 3 and 4 leukopenia (52% vs 37%) and neutropenia (24% vs 12%), but grade 3 and 4 acute radiation toxicities were not statistically different between the 2 arms. The global quality of life scores were comparable in both arms. Conclusion: Induction chemotherapy with GCP before concurrent chemo-irradiation did not improve survival in locally advanced NPC.

    Purpose: The numbers of circulating tumor cells (CTCs) and their expression/activation of epidermal growth factor receptor (EGFR) during the course of combined chemo- or bioradiotherapy regimens as potential biomarkers of treatment efficacy in squamous cell carcinoma of the head and neck (SCCHN) were determined. Methods and Materials: Peripheral blood samples from SCCHN patients with locally advanced stage IVA/B disease who were treated with concurrent radiochemotherapy or induction chemotherapy followed by bioradiation with cetuximab were included in this study. Using flow cytometry, the absolute number of CTCs per defined blood volume as well as their expression of EGFR and its phosphorylated form (pEGFR) during the course of treatment were assessed. Results: Before treatment, we detected {>=}1 CTC per 3.75 mL blood in 9 of 31 patients (29%). Basal expression of EGFR was detected in 100% and pEGFR in 55% of the CTC+ cases. The frequency of CTC detection was not influenced by induction chemotherapy. However, the number of CTC+ samples significantly increased after radiotherapy. This radiation-induced increase in CTC numbers was less pronounced when radiotherapy was combined with cetuximab compared to its combination with cisplatin/5-fluorouracil. The former treatment regimen was also more effective in reducing pEGFR expression in CTCs. Conclusions: Definitive radiotherapy regimens of locally advanced SCCHN can increase the number of CTCs and might thus contribute to a systemic spread of tumor cells. Further studies are needed to evaluate the predictive value of the radiation-induced increase in CTC numbers and the persistent activation of the EGFR signalling pathway in individual CTC+ cases.

    Patients with metastatic urothelial carcinoma (mUC) who progress after platinum-based chemotherapy have had few treatment options and uniformly poor outcomes. Atezolizumab (anti-programmed death-ligand 1) was approved in the USA for cisplatin-ineligible and platinum-treated mUC based on IMvigor210, a phase 2, single-arm, two-cohort study. To evaluate the efficacy and safety of atezolizumab by the number of prior lines of systemic therapy in patients with pretreated mUC. IMvigor210 enrolled 315 patients with mUC with progression during or following platinum-based therapy at 70 international sites between May 2014 and November 2014. Key inclusion criteria included age ≥18 yr, creatinine clearance ≥30ml/min, and Eastern Cooperative Oncology Group performance status 0-1, with no limit on prior lines of treatment. Patients in this cohort received atezolizumab 1200mg intravenously every 3 wk until loss of clinical benefit. Centrally assessed Response Evaluation Criteria In Solid Tumors v1.1 objective response rate (ORR), median duration of response, overall survival (OS), and adverse events were evaluated by prior treatment. Potential differences between subgroups were evaluated using log-rank (for OS) and chi-square (for ORR and adverse events frequencies) testing. Three hundred and ten patients were efficacy and safety evaluable (median follow-up, 21 mo). Objective responses and prolonged OS occurred across all prespecified subgroups; median duration of response was not reached in most subgroups. In patients without prior systemic mUC therapy (first-line subgroup), ORR was 25% (95% confidence interval: 14-38), and median OS was 9.6 mo (95% confidence interval: 5.9-15.8). No significant differences in efficacy or toxicity by therapy line were observed. Atezolizumab demonstrated comparable efficacy and safety in previously treated patients with mUC across all lines of therapy evaluated. We investigated effects of previous treatment in patients with metastatic

    Proton-beam radiotherapy (PBT) has been shown to be effective to hepatocellular carcinoma (HCC) as a nonsurgical local treatment option. However, HCC still remains as one of the most difficult cancers to be cured because of frequent recurrences. Thus, methods to inhibit the recurrence need to be explored. To prevent the HCC recurrence, we here report on a prospective phase I study of ‘in situ’ tumor vaccination using CalTUMP, a newly developed immunoadjuvant consisting of BCG extract bound to hydroxyapatite and microparticulated tuberculin, following local PBT for HCC. Patients with locally advanced recurrent HCC, which had been heavily pretreated with various treatments, were enrolled. PBT was performed with the conventional method to the target HCC. Subsequently, CalTUMP was injected into the same irradiated-tumor three times at one-week intervals. Three dose-levels of CalTUMP (1/10, 1/3, and 1/1) were administered to 3 patients each. Vital signs, blood samples, ultrasound, and computed tomographic scans were monitored to evaluate the safety. Three intratumoral injections of CalTUMP following PBT (median dose: 72.6 GyE) were accomplished in 9 patients. Transient low-grade fever and minor laboratory changes were observed in 7 patients after CalTUMP injections. No other treatment-related adverse events were observed. Median progression-free survival was 6.0 months (range: 2.1-14.2) and 4 patients were progression-free for more than 1 year. Intratumoral injection of CalTUMP following PBT was feasible and safe in patients with heavily pre-treated HCC. Further clinical studies to evaluate the efficacy of this in situ tumor vaccination are warranted

    Surgery is the mainstay of treatment for oesophageal squamous-cell carcinoma (OSCC) but with poor results. Attempts to improve patient outcome have been made by introducing chemotherapy (CT), radiotherapy (RT), or both (CRT). However, randomized comparisons for all these strategies are not always available. We conducted an extensive literature search for studies comparing surgery with multimodality treatment (i.e. [neo-]adjuvant CT or RT or CRT or definitive CRT). Network meta-analysis was performed in a Bayesian framewor and node-split models were built to assess inconsistency. Twenty-five trials including a total of 3866 OSCC patients were included. Neoadjuvant CRT was associated with the most robust survival advantage across different multimodality treatment options (HR 0.73; 95% credible interval [CrI] 0.63-0.86). Definitive CRT was also significantly more effective than surgery but with greater uncertainties (HR 0.62; 95%CrI 0.41-0.96). Neoadjuvant CT (HR 0.90; 95%CrI 0.76-1.07) and adjuvant CRT (HR 1.00; 95%CrI 0.70-1.40) are associated with a non-significant benefit. To date, neoadjuvant CRT seems to represent the best approach to maximize the benefit of a multimodality approach. Copyright © 2017 Elsevier B.V. All rights reserved.

    Purpose: Newer radiation techniques, and the application of continuous 5-FU exposure during radiation therapy using oral capecitabine may improve the treatment of anal cancer. This phase 1, dose-finding study assessed the feasibility and efficacy of simultaneous integrated boost–intensity modulated radiation therapy (SIB-IMRT) with concomitant capecitabine and mitomycin C in locally advanced anal cancer, including pharmacokinetic and pharmacogenetic analyses. Methods and Materials: Patients with locally advanced anal carcinoma were treated with SIB-IMRT in 33 daily fractions of 1.8 Gy to the primary tumor and macroscopically involved lymph nodes and 33 fractions of 1.5 Gy electively to the bilateral iliac and inguinal lymph node areas. Patients received a sequential radiation boost dose of 3 × 1.8 Gy on macroscopic residual tumor if this was still present in week 5 of treatment. Mitomycin C 10 mg/m{sup 2} (maximum 15 mg) was administered intravenously on day 1, and capecitabine was given orally in a dose-escalated fashion (500-825 mg/m{sup 2} b.i.d.) on irradiation days, until dose-limiting toxicity emerged in ≥2 of maximally 6 patients. An additional 8 patients were treated at the maximum tolerated dose (MTD). Results: A total of 18 patients were included. The MTD of capecitabine was determined to be 825 mg/m{sup 2} b.i.d. The predominant acute grade ≥3 toxicities included radiation dermatitis (50%), fatigue (22%), and pain (6%). Fifteen patients (83% [95%-CI: 66%-101%]) achieved a complete response, and 3 (17%) patients a partial response. With a median follow-up of 28 months, none of the complete responders, and 2 partial responders had relapsed. Conclusions: SIB-IMRT with concomitant single dose mitomycin C and capecitabine 825 mg/m{sup 2} b.i.d. on irradiation days resulted in an acceptable safety profile, and proved to be a tolerable and effective treatment regimen for locally advanced anal cancer.

    Purpose: the study was designed to assess prospectively the efficacy of GM-CSF (granulocyte-macrophage colony-stimulating factor) mouthwash solution in the management of chemoirradiation induced oral mucositis for head and neck cancer patients. Methods and materials: thirty-five patients with advanced carcinoma of the head and neck were evaluated for mucositis during the first cycle of chemoirradiation therapy. GM-CSF 400 μg in 250 cc of water for 1 h of mouth washing was prescribed. Active comparator was a conventional mucositis therapy combination. The procedure started once mucositis grade 1 (using the WHO grading) was detected. Patients, examined twice a week, were evaluated for oral mucositis and oral infections. Assessment of subjective pain was provided using a visual analogue scale. Blood tests were taken weekly. Results: the results of statistical evaluation of mucositis using the WHO-grading showed no significant differences between the two treatment groups. Local application of GM-CSF significantly reduced subjective pain during the second week of chemoirradiation therapy. Statistical analysis of the leucocytes-, platelet count, haemoglobin level and development of oral infections revealed no significant differences between the two treatment groups. Conclusion: in combined chemoirradiation therapy schemes the RTOG/EORTC toxicity scale should be used. In selected cases of mucositis attended with severe pain, GM-CSF should be observed within the therapeutic considerations. Controlled clinical trials with larger patient population are required to evaluate the role of GM-CSF in this indication. (author)

    To investigate the potential prognostic role of tumor cell podoplanin expression in patients treated with resection followed by irradiation or chemoradiotherapy for locally advanced squamous cell carcinoma of the head and neck (SCCHN). Podoplanin expression (≤10 % versus > 10 %) and 12 other factors were evaluated in 160 patients for their association with locoregional control (LRC), metastases-free (MFS) and overall survival (OS). Other factors were age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, preradiotherapy (pre-RT) hemoglobin level, tumor site, histological grading, T category, N category, American Joint Committee on Cancer (AJCC) stage, human papillomavirus (HPV) status, extent of resection and concurrent chemotherapy. In multivariate analysis, ECOG performance status 0-1 (risk ratio, RR: 3.01; 95 % confidence interval, CI: 1.42-7.14; p = 0.003), pre-RT hemoglobin levels ≥ 7.45 mmol/l (12 g/dl; RR: 2.03; 95 % CI: 1.04-3.94; p = 0.038), oropharyngeal cancer (RR: 1.25; 95 % CI: 1.01-1.55; p = 0.038) and T category T1-2 (RR: 1.81; 95 % CI: 1.24-2.79; p = 0.002) were significantly associated with improved LRC. T category T1-2 (RR: 1.90; 95 % CI: 1.25-3.06; p = 0.002) and N category N0-2a (RR: 5.22; 95 % CI: 1.96-18.09; p 10 %. (orig.) [de

However, the publication of new studies and the fact that many older studies that were included in these former meta-analyses used obsolete radiation doses, CHX schedules or study designs prompted us to carry out a new analysis using strict inclusion criteria. Methods Randomised trials testing curatively intended RT (≥60 Gy in >4 weeks/>50 Gy in Results Thirty-two trials with a total of 10 225 patients were included into the meta-analysis. An overall survival benefit of 12.0 months was observed for the addition of simultaneous CHX to either CFRT or HFRT/AFRT (p Conclusion RT combined with simultaneous 5-FU, cisplatin, carboplatin, and mitomycin C as single drug or combinations of 5-FU with one of the other drugs results in a large survival advantage irrespective the employed radiation schedule. If radiation therapy is used as single modality, hyperfractionation leads to a significant improvement of overall survival. Accelerated radiation therapy alone, especially when given as split course radiation schedule or extremely accelerated treatments with decreased total dose, does not increase overall survival.

    The technology of curietherapy for esophagus shows its feasibility and its interest in advanced tumors of esophagus, by association with external radiotherapy and/or association radio-chemotherapy. It allows to deliver a high dose in the heart of the tumor with a tolerable toxicity. Its efficiency and the analysis of toxicity should be reevaluated at long term. Its place should be discussed in randomized protocols proposed to this selection of patients

    Background and purpose: the optimal radiochemotherapy regimen for advanced head-and-neck cancer is still debated. This nonrandomized study compares two cisplatin-based radiochemotherapy regimens in 128 patients with locally advanced unresectable stage IV squamous cell carcinoma of the head and neck (SCCHN). Patients and methods: concurrent chemotherapy consisted of either two courses cisplatin (20 mg/m{sup 2}/d1-5 + 29-33; n = 54) or two courses cisplatin (20 mg/m{sup 2}/d1-5 + 29-33) + 5-fluorouracil (5-FU; 600 mg/m{sup 2}/d1-5 + 29-33; n = 74). Results: at least one grade 3 toxicity occurred in 25 of 54 patients (46%) receiving cisplatin alone and in 52 of 74 patients (70%) receiving cisplatin + 5-FU. The latter regimen was particularly associated with increased rates of mucositis (p = 0.027) and acute skin toxicity (p = 0.001). Seven of 54 (13%) and 20 of 74 patients (27%) received only one chemotherapy course due to treatment-related acute toxicity. Late toxicity in terms of xerostomia, neck fibrosis, skin toxicity, and lymphedema was not significantly different. The 2-year locoregional control rates were 67% after cisplatin alone and 52% after cisplatin + 5-FU (p = 0.35). The metastases-free survival rates were 79% and 69%, respectively (p = 0.65), and the overall survival rates 70% and 51%, respectively (p = 0.10). On multivariate analysis, outcome was significantly associated with performance status, T-category, N-category, hemoglobin level prior to radiotherapy, and radiotherapy break > 1 week. Conclusion: two courses of fractionated cisplatin (20 mg/m{sup 2}/day) alone appear preferable, as this regimen resulted in similar outcome and late toxicity as two courses of cisplatin + 5-FU, but in significantly less acute toxicity.

    Purpose: A Phase II multicenter trial testing an accelerated regimen of radiotherapy in locally advanced and inoperable cancers of the head and neck, in patients selected on the basis of 5-bromo-2-deoxyuridine/DNA flow cytometry-derived tumor potential doubling time (T pot ). Methods and Materials: From September 1992 to September 1993, 23 patients consecutively diagnosed to have locally advanced, inoperable carcinomas of the oral cavity and the oropharynx, with T pot of ≤5 days, received an accelerated radiotherapy regimen (AF) based on a modification of the concomitant boost technique: 2 Gy/fraction once a day, delivered 5 days a week up to 26 Gy, followed by 2 Gy/fraction twice a day, with a 6-h interval, one of the two fractions being delivered as a concomitant boost to reduced fields, up to 66 Gy total dose (off-cord reduction at 46 Gy), shortening the overall treatment time to 4.5 weeks. A contemporary control group of 46 patients with T pot of >5 days or unknown was treated with conventional fractionation (CF): 2 Gy/fraction once a day, 5 days a week, up to 66 Gy in 6.5 weeks, with fields shrinkage after 46 Gy. Results: All patients completed the accelerated regimen according to protocol and in the prescribed overall treatment time. Immediate tolerance was fairly good: 65% of the patients in the AF group experienced Grade 3 mucositis vs. 45% in the CF group (p = n.s.). Symptoms related to mucosal reactions seemed to persist longer in AF than in CF patients. The crude proportion of mild (Grades 1 and 2) late effects on skin (p < 0.01) and salivary glands (p < 0.05) was higher in AF than in CF patients, although these reactions did not exceed the limits of tolerance. Three patients in the AF and 1 in the CF arm experienced a late Grade 4 bone complication. Actuarial estimates of severe (Grades 3 and 4) late complications showed a 2-year hazard of 33.3% in the AF arm and 49.7% in CF (p = NS). The actuarial 2-year local control rate of the AF patients was 49

    The prognostic effect of pretreatment patient- and tumor characteristics, and the influence of radiotherapy schedule on local control, distant metastases, and crude survival were analyzed in 424 consecutive patients with FIGO stage IIB (n = 137), IIIA (n = 10), IIIB (n = 211) and IVA (n = 66) cancer of the uterine cervix. All patients were given radiotherapy alone. From 1974 and through 1977, the external and intracavitary combined radiotherapy was given continuously in 4 to 6 weeks. From 1978 and through 1983, the treatment policy was changed to split-course radiotherapy by introducing planned pauses, resulting in an overall treatment time of 10 to 12 weeks. The results were estimated by univariate actuarial- and Cox multivariate regression analyses. Multivariate analysis showed that significant adverse variables for local control were large lateral tumor diameter, young age, low hemoglobin at time of admission, many prognancies, split-course strategy, and high FIGO stage. Risk of metastases increased with decreasing hemoglobin, increasing malignancy grade and split-course treatment. Poor survival probability were related to large lateral tumor diameter, high malignancy grade and FIGO stage, low hemoglobin, split-course therapy, and adeno/adenosquamous tumor type. (orig.)

    This study aimed to evaluate the prognostic value of plasma Epstein-Barr Virus DNA (EBV DNA) for local and regionally advanced nasopharyngeal carcinoma (NPC) patients treated with concurrent chemoradiotherapy in intensity-modulated radiotherapy (IMRT) era.In this observational study, 404 nonmetastatic local and regionally advanced NPC patients treated with IMRT and cisplatin-based concurrent chemotherapy were recruited. Blood samples were collected before treatment for examination of plasma EBV DNA levels. We evaluated the association of pretreatment plasma EBV DNA levels with progression-free survival rate (PFS), distant metastasis-free survival rate (DMFS), and overall survival rate (OS).Compared to patients with an EBV DNA level advanced NPC patients treated with IMRT and cisplatin-based concurrent chemotherapy. Future ramdomized clinical trials are needed to further evaluate whether plasma EBV DNA levels could be applied to guide concurrent chemotherapy regimen for local and regionally advanced NPC patients.

    Purpose: The objectives of this study were to determine the efficacy and toxicity of Etanidazole (ETA), a hypoxic cell sensitizer, when combined with conventional radiotherapy (RT) in the management of advanced head and neck carcinomas. Methods and Materials: From March 1988 to September 1991, 521 patients who had Stage III or IV head and neck carcinomas were randomized to receive conventional RT alone (66 Gy in 33 fractions to 74 Gy in 37 fractions, 5 fractions per week) or RT + ETA (2.0 g/m{sup 2} thrice weekly for 17 doses), of whom 504 were eligible and analyzable. Treatment assignments were stratified before randomization according to the primary site (oral cavity + hypopharynx vs. supraglottic larynx + oropharynx + nasopharynx), T-stage (T1-3 vs. T4), and N-stage (N0-2 vs. N3). Pretreatment characteristics were balanced. In the RT-alone arm, 39% of patients had T3 and 34% had T4 disease, whereas in the RT + ETA arm, 42% of patients had T3 and 33% had T4 disease. Thirty-eight percent of the RT-alone patients and 37% of the RT + ETA patients had N3 disease. The median follow-up of surviving patients was 3.38 years, with a range between 0.96 and 5.63 years. Results: One hundred and ninety-four of the 252 (77%) RT + ETA patients received at least 14 doses of the drug. Overall RT protocol compliance rate was 82% in the RT-alone arm and 86% in the RT + ETA arm. No Grade 3 or 4 central nervous system or peripheral neuropathy was observed in the RT + ETA arm. Eighteen percent of the patients developed Grade 1 and 5% developed Grade 2 peripheral neuropathy. Other drug related toxicities included nausea/vomiting (27%), low blood counts (15%), and allergy (9%). Most of these toxicities were Grade 1 and 2. The incidence of severe acute and late radiation effects were similar between the two arms. The 2-year actuarial local-regional control rate (LCR) was 40% for the RT-alone arm and 40% for the RT + ETA arm. Two-year actuarial survival was 41% for the RT-alone arm and 43

    The purpose of this study was to evaluate the early and late radiotherapeutic morbidity after combined external and intracavitary radiotherapy to the uterine cervix. Early morbidity was most frequently seen in the rectosigmoideum (61%) and urinary bladder (27%). Medication for early morbidity was required 68% and hospitalization in 10% of the patients. The frequencies of each late morbidity grade did not differ in relation to FIGO State while the actuarial estimates increased significantly with increasing stage. This reflects the poor prognosis in the more advanced stages, where few patients survived to develop late morbidity, and also points to the importance of latency in reporting late radiotherapeutic morbidity. In Stage IVA patients, the ratios between the actuarial estimate and the frequency of late severe rectosigmoid and urinary bladder morbidity were as high as 2.5 and 3, respectively. The highest 5-year risk (± 1 SE of the estimate) of late severe morbidity were found for the rectosignoideum (28% ± 3), small intestine (13% ± 2) and urinary bladder (10% ± 2). Rectosigmoid and urinary bladder complications constituted the most important part of the combined organ morbidity. Almost half of the patients developing late moderate rectosigmoid and one-third of those developing late moderate bladder complications, did so within one year after radiotherapy. Almost all complications were developed within 3 to 4 years after radiotherapy. The probability of surviving without recurrence and/or severe combined rectosigmoid and urinary bladder morbidity was low (23% ± 2). Actuarial estimates rather than frequencies should be reported to avoid underestimation of the risk of late radiotherapeutic morbidity in long-term survivors. 29 refs., 5 figs. 7 tabs

    Conventional criteria for tumor progression may not fully reflect the clinical benefit of immunotherapy or appropriately guide treatment decisions. The phase II IMvigor210 study demonstrated the efficacy and safety of atezolizumab, a programmed death-ligand 1-directed antibody, in patients with platinum-treated locally advanced or metastatic urothelial carcinoma. Patients could continue atezolizumab beyond Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 progression at the investigator's discretion: this analysis assessed post-progression outcomes in these patients. Patients were treated with atezolizumab 1200 mg i.v. every 3 weeks until loss of clinical benefit. Efficacy and safety outcomes in patients who experienced RECIST v1.1 progression and did, or did not, continue atezolizumab were analyzed descriptively. In total, 220 patients who experienced progression from the overall cohort (n = 310) were analyzed: 137 continued atezolizumab for ≥ 1 dose after progression, 19 received other systemic therapy, and 64 received no further systemic therapy. Compared with those who discontinued, patients continuing atezolizumab beyond progression were more likely to have had a baseline Eastern Cooperative Oncology Group performance status of 0 (43.1% versus 31.3%), less likely to have had baseline liver metastases (27.0% versus 41.0%), and more likely to have had an initial response to atezolizumab (responses in 11.7% versus 1.2%). Five patients (3.6%) continuing atezolizumab after progression had subsequent responses compared with baseline measurements. Median post-progression overall survival was 8.6 months in patients continuing atezolizumab, 6.8 months in those receiving another treatment, and 1.2 months in those receiving no further treatment. Atezolizumab exposure-adjusted adverse event frequencies were generally similar before and following progression. In this single-arm study, patients who continued atezolizumab beyond RECIST v1

    Oral squamous cell carcinomas comprise a heterogeneous tumor cell population with varied molecular characteristics, which makes prognostication of these tumors a complex and challenging issue. Thus, molecular profiling of these tumors is advantageous for an accurate prognostication and treatment planning. This is a retrospective study on a cohort of primary locally advanced oral squamous cell carcinomas (n = 178) of an Indian rural population. The expression of EGFR, p53, cyclin D1, Bcl-2 and p16 in a cohort of primary locally advanced oral squamous cell carcinomas was evaluated. A potential biomarker that can predict the tumor response to treatment was identified. Formalin-fixed paraffin-embedded tumor blocks of (n = 178) of histopathologically diagnosed cases of locally advanced oral squamous cell carcinomas were selected. Tissue microarray blocks were constructed with 2 cores of 2 mm diameter from each tumor block. Four-micron-thick sections were cut from these tissue microarray blocks. These tissue microarray sections were immunohistochemically stained for EGFR, p53, Bcl-2, cyclin D1 and p16. In this cohort, EGFR was the most frequently expressed 150/178 (84%) biomarker of the cases. Kaplan-Meier analysis showed a significant association (p = 0.038) between expression of p53 and a poor prognosis. A Poisson regression analysis showed that tumors that expressed p53 had a two times greater chance of recurrence (unadjusted IRR-95% CI 2.08 (1.03, 4.5), adjusted IRR-2.29 (1.08, 4.8) compared with the tumors that did not express this biomarker. Molecular profiling of oral squamous cell carcinomas will enable us to categorize our patients into more realistic risk groups. With biologically guided tumor characterization, personalized treatment protocols can be designed for individual patients, which will improve the quality of life of these patients.

    Definitive radiotherapy and vismodegib, an oral inhibitor of the hedgehog pathway, are both established treatment options for locally advanced basal cell carcinomas (BCC). Both have shown good results in local tumor control; however, the effects concerning advanced tumors are often not of a lasting nature and to date no systematic data about the combination of the two modalities are available. We retrospectively analyzed four patients who received vismodegib and radiotherapy in combination. Radiation doses varied between 50.4 Gy and 66.0 Gy. Three patients had recurrent BCC. One patient had locoregional lymph node involvement. Vismodegib was taken once a day (150 mg) during the entire time of irradiation and beyond upon instructions of the attending dermatologist. In three cases a persistent complete response was observed, in one case the tumor remained stable for approximately 6 months until further tumor progression was documented. The combined therapy was well tolerated in all cases. No exceptional side effects pointing at a drug-radiation interaction were observed. The combination of vismodegib and radiation seems feasible and the initial results are promising. In our cohort, there was no increase in unexpected side effects. Further research is needed to evaluate the significance of this combined therapy. (orig.)

    Human papillomavirus type 16 (HPV-16) positivity is associated with favourable survival in oropharyngeal squamous cell carcinoma (OPSCC). We report here a study of the prognostic significance of 18 F-FDG PET/CT functional parameters and HPV-16 infection in OPSCC patients. We retrospectively analysed 60 patients with stage III or IV OPSCC who had had a pretherapy 18 F-FDG PET/CT scan and had completed concurrent chemoradiotherapy (n = 58) or curative radiotherapy (n = 2). All patients were followed up for ≥24 months or until death. We determined total lesion glycolysis (TLG) and the maximal standardized uptake values (SUV max ) of the primary tumour and neck lymph nodes from the pretherapy 18 F-FDG PET/CT scan. Optimal cut-offs of the 18 F-FDG PET/CT parameters were obtained by receiver operating characteristic (ROC) curve analyses. Pretherapy tumour biopsies were studied by polymerase chain reaction to determine HPV infection status. The pretherapy tumour biopsies were positive for HPV-16 in 12 patients (20.0 %). Cox regression analyses revealed HPV-16 positivity and tumour TLG >135.3 g to be independently associated with overall survival (p = 0.027 and 0.011, respectively). However, only tumour TLG >135.3 g was independently associated with progression-free survival, disease-free survival and locoregional control (p = 0.011, 0.001 and 0.034, respectively). A scoring system was formulated to define distinct overall survival groups using tumour TLG and HPV-16 status. Patients positive for HPV-16 and with tumour TLG ≤135.3 g experienced better survival than those with tumour TLG >135.3 g and no HPV infection (p = 0.001). Tumour TLG was an independent predictor of survival in patients with locally advanced OPSCC. A scoring system was developed and may serve as a risk stratification strategy for guiding therapy.

    Purpose: To analyze the relationship between overall survival (OS) and radiation treatment time (RTT) and overall treatment time (OTT) in a well-described sequential therapy paradigm for locally advanced head-and-neck carcinoma (LAHNC). Methods and Materials: TAX 324 is a Phase III study comparing TPF (docetaxel, cisplatin, and fluorouracil) with PF (cisplatin and fluorouracil) induction chemotherapy (IC) in LAHNC patients; both arms were followed by carboplatin-based chemoradiotherapy (CRT). Prospective radiotherapy quality assurance was performed. This analysis includes all patients who received three cycles of IC and a radiation dose of ≥ 70 Gy. Radiotherapy treatment time was analyzed as binary (≤ 8 weeks vs. longer) and continuous (number of days beyond 8 weeks) functions. The primary analysis assessed the relationship between RTT, OTT, and OS, and the secondary analysis explored the association between treatment times and locoregional recurrence (LRR). Results: A total of 333 (of 501) TAX 324 patients met the criteria for inclusion in this analysis. There were no significant differences between the treatment arms in baseline or treatment characteristics. On multivariable analysis, PF IC, World Health Organization performance status of 1, non-oropharynx site, T3/4 stage, N3 status, and prolonged RTT (hazard ratio 1.63, p = 0.006) were associated with significantly inferior survival. Performance status, T3/4 disease, and prolonged RTT (odds ratio 1.68, p = 0.047) were independently and negatively related to LRR on multivariable analysis, whereas PF was not. Overall treatment time was not independently associated with either OS or LRR. Conclusions: In this secondary analysis of the TAX 324 trial, TPF IC remains superior to PF IC after controlling for radiotherapy delivery time. Even with optimal IC and concurrent chemotherapy, a non-prolonged RTT is a crucial determinant of treatment success. Appropriate delivery of radiotherapy after IC remains essential

    Concurrent chemoradiotherapy followed by adjuvant chemotherapy (CCRT-AC) has been established as the standard of care in locally advanced nasopharyngeal carcinoma (LA-NPC). The survival benefit of induction chemotherapy (ICT) for LA-NPC remains controversial. We analyzed the efficacy and feasibility of docetaxel, cisplatin and 5-fluorouracil (TPF) ICT followed by CCRT for LA-NPC with nodal Stage N2-3. We performed a retrospective analysis of 28 LA-NPC patients with nodal Stage N2-3 receiving induction TPF followed by CCRT (TPF group; n = 12) or CCRT-AC (CCRT group; n = 16) between October 2006 and May 2016. The median follow-up periods were 36.4 (range 6.7-55.2) and 40.1 months (range 4.3-99.0) for the TPF and CCRT groups, respectively. One- and three-year overall survival for the TPF group vs. the CCRT group were 100% and 100% vs. 94% and 75%, respectively (P = 0.21). The cumulative one- and three-year incidences of locoregional recurrence or progression for the TPF group vs. the CCRT group were 10% and 21% vs. 16% and 32% (P = 0.49), and those of distant metastasis were 0% and 0% vs. 26% and 26%, respectively (P = 0.08). The common Grade 3-4 acute toxicities were neutropenia, anorexia, febrile neutropenia, and stomatitis in the TPF group. The Grade 3-4 late toxicities did not differ significantly between the two groups. This study suggests that induction TPF followed by CCRT might reduce distant metastasis, so this combination may be feasible for the treatment of LA-NPC with nodal Stage N2-3. © The Author 2017.

    Human papillomavirus type 16 (HPV-16) positivity is associated with favourable survival in oropharyngeal squamous cell carcinoma (OPSCC). We report here a study of the prognostic significance of {sup 18}F-FDG PET/CT functional parameters and HPV-16 infection in OPSCC patients. We retrospectively analysed 60 patients with stage III or IV OPSCC who had had a pretherapy {sup 18}F-FDG PET/CT scan and had completed concurrent chemoradiotherapy (n = 58) or curative radiotherapy (n = 2). All patients were followed up for {>=}24 months or until death. We determined total lesion glycolysis (TLG) and the maximal standardized uptake values (SUV{sub max}) of the primary tumour and neck lymph nodes from the pretherapy {sup 18}F-FDG PET/CT scan. Optimal cut-offs of the {sup 18}F-FDG PET/CT parameters were obtained by receiver operating characteristic (ROC) curve analyses. Pretherapy tumour biopsies were studied by polymerase chain reaction to determine HPV infection status. The pretherapy tumour biopsies were positive for HPV-16 in 12 patients (20.0 %). Cox regression analyses revealed HPV-16 positivity and tumour TLG >135.3 g to be independently associated with overall survival (p = 0.027 and 0.011, respectively). However, only tumour TLG >135.3 g was independently associated with progression-free survival, disease-free survival and locoregional control (p = 0.011, 0.001 and 0.034, respectively). A scoring system was formulated to define distinct overall survival groups using tumour TLG and HPV-16 status. Patients positive for HPV-16 and with tumour TLG {<=}135.3 g experienced better survival than those with tumour TLG >135.3 g and no HPV infection (p = 0.001). Tumour TLG was an independent predictor of survival in patients with locally advanced OPSCC. A scoring system was developed and may serve as a risk stratification strategy for guiding therapy.

Materials and Methods: Four hundred and sixty patients suffering from locally advanced HNSCC and an equal number of healthy controls were genotyped for CYP2C9FNx012 and CYP2C9FNx013, leading to poor metabolizers (PMs by polymerase chain reaction (PCR-based restriction fragment length polymorphism (RFLP. Each case was assessed thoroughly for treatment response as per the World Health Organization (WHO criteria. Results and Analysis: The frequency of heterozygous genotypes of both CYP2C9FNx012 (27.8% and CYP2C9FNx013 (25% were found to be significantly higher in the HNSCC cases as compared to the healthy controls. Tobacco intake in the form of chewing or smoking and alcohol intake resulted in several folds increase in the risk to HNSCC in the cases carrying variant genotypes of CYP2C9FNx012 or CYP2C9FNx013. Further, majority of the cases assessed for response (n = 436 carrying variant alleles of CYP2C9FNx012 (69.6% or CYP2C9FNx013 (65.2% were found to respond poorly to cisplatin-based radical CT-RT. Conclusion: The data suggests a significant association of the CYP2C9 polymorphism with HNSCC and treatment outcome underlining the importance of pretherapeutic genotyping in determining the treatment protocol.

    Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified. The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient at-risk for developing HCC. The diagnosis of HCC can be based on non-invasive criteria (only in cirrhotic patient) or pathology. Accurately staging patients is essential to oncology practice. The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function. Treatment allocation is based on several factors: Liver function, size and number of tumours, macrovascular invasion or extrahepatic spread. The recommendations in terms of selection for different treatment strategies must be based on evidence-based data. Resection, liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates. Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment. Finally, in patients with advanced HCC with preserved liver function, sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

    We evaluated the usefulness of chemotherapy with gemcitabine for unresectable advanced pancreatic carcinoma. We examined 121 cases with unresectable advanced pancreatic carcinoma. They consisted of 65 locally advanced cases with no distant metastasis (Stage IVa) and 56 cases with distant metastasis (Stage IVb). Seventy-three cases were treated by chemotherapy with only gemcitabine (GEM) alone. Forty cases were not treated. Eight cases received chemoradiotherapy (CRT) combined with GEM. Their survival curves were compared. The survival curve of the GEM group was significantly longer than that of the no therapy group. In the locally advanced and distant metastasis groups, the survival curve of the GEM group was significantly longer than that of the no therapy group. And in the GEM group, the survival curve of the locally advanced group was significantly longer than that of the distant metastasis group. The survival curve of the CRT group was significantly longer than that of GEM group. Chemotherapy with gemcitabine for unresectable advanced pancreatic carcinoma was useful but the prognosis remained poor. (author)

    Impact of non-pharmacological innovations on cancer cure rates is difficult to assess. It remains unclear, whether outcome improves with 2- [18-F]-fluoro-2-deoxyglucose-positron emission tomography and integrated computer tomography (PET/CT) and intensity-modulated radiotherapy (IMRT) for curative treatment of advanced pharyngeal carcinoma. Forty five patients with stage IVA oro- or hypopharyngeal carcinoma were staged with an integrated PET/CT and treated with definitive chemoradiation with IMRT from 2002 until 2005. To estimate the impact of PET/CT with IMRT on outcome, a case-control analysis on all patients with PET/CT and IMRT was done after matching with eighty six patients treated between 1991 and 2001 without PET/CT and 3D-conformal radiotherapy with respect to gender, age, stage, grade, and tumor location with a ratio of 1:2. Median follow-up was eighteen months (range, 6–49 months) for the PET/CT-IMRT group and twenty eight months (range, 1–168 months) for the controls. PET/CT and treatment with IMRT improved cure rates compared to patients without PET/CT and IMRT. Overall survival of patients with PET/CT and IMRT was 97% and 91% at 1 and 2 years respectively, compared to 74% and 54% for patients without PET/CT or IMRT (p = 0.002). The event-free survival rate of PET/CT-IMRT group was 90% and 80% at 1 and 2 years respectively, compared to 72% and 56% in the control group (p = 0.005). PET/CT in combination with IMRT and chemotherapy for pharyngeal carcinoma improve oncological therapy of pharyngeal carcinomas. Long-term follow-up is needed to confirm these findings

    Purpose: To study the efficacy of reirradiation as salvage treatment in patients with locally recurrent nasopharyngeal carcinoma. Patients and Methods: Between 1993 and 2000, 20 consecutive patients (twelve males and eight females) with nasopharyngeal cancer, previously irradiated in different Hungarian institutions, were reirradiated for biopsy-proven locally recurrent tumor. Histologically, 85% of the patients had WHO type III, 5% type II, and 10% type I disease. Stages I-IV (AJCC 1997 staging system) were assigned to five (25%), seven (35%), five (25%), and three (15%) patients, respectively; none of them had distant metastases, and only eight (40%) displayed regional dissemination. The median time period between termination of primary treatment and local recurrence was 30 (range, 10-204) months. Brachytherapy was the method most frequently used: in ten cases alone (especially for rT1 tumors), and in eight cases in combination with external beam therapy. Two patients with locally advanced disease underwent external beam therapy only. The median dose in the event of brachytherapy alone was 20 Gy (4 x 5 Gy or 5 x 4 Gy, range, 16-36 Gy), and the dose range for exclusive external irradiation was 30-40 Gy. In cases of combined irradiation, a median 20-Gy brachytherapy (range 16-40 Gy) was associated with 30-40 Gy of external irradiation. Radiotherapy was supplemented by neck dissection (six patients), nasopharyngectomy (one patient), or chemotherapy (eleven patients). Results: 16 patients were reirradiated once, three twice, and one patient three times, with a median equivalent dose for tumor effect of 36 Gy (mean, 44 Gy; range, 19-117 Gy; the estimated {alpha}/{beta}-ratio was 10 Gy). The median equivalent dose of reirradiation for late effect on normal tissue (with an estimated 70% delivery of the tumor dose) amounted to 30 Gy (mean, 37 Gy; range, 13-101 Gy, estimated {alpha}/{beta}-ratio 3 Gy). After a median follow-up of 37 (range, 12-72) months, the overall

    Purpose: To evaluate the toxicity and clinical outcome in patients with locally advanced cervical cancer (LACC) treated with whole pelvic conventional radiation therapy (WP-CRT) versus intensity modulated radiation therapy (WP-IMRT). Methods and Materials: Between January 2010 and January 2012, 44 patients with International Federation of Gynecology and Obstetrics (FIGO 2009) stage IIB-IIIB squamous cell carcinoma of the cervix were randomized to receive 50.4 Gy in 28 fractions delivered via either WP-CRT or WP-IMRT with concurrent weekly cisplatin 40 mg/m{sup 2}. Acute toxicity was graded according to the Common Terminology Criteria for Adverse Events, version 3.0, and late toxicity was graded according to the Radiation Therapy Oncology Group system. The primary and secondary endpoints were acute gastrointestinal toxicity and disease-free survival, respectively. Results: Of 44 patients, 22 patients received WP-CRT and 22 received WP-IMRT. In the WP-CRT arm, 13 patients had stage IIB disease and 9 had stage IIIB disease; in the IMRT arm, 12 patients had stage IIB disease and 10 had stage IIIB disease. The median follow-up time in the WP-CRT arm was 21.7 months (range, 10.7-37.4 months), and in the WP-IMRT arm it was 21.6 months (range, 7.7-34.4 months). At 27 months, disease-free survival was 79.4% in the WP-CRT group versus 60% in the WP-IMRT group (P=.651), and overall survival was 76% in the WP-CRT group versus 85.7% in the WP-IMRT group (P=.645). Patients in the WP-IMRT arm experienced significantly fewer grade ≥2 acute gastrointestinal toxicities (31.8% vs 63.6%, P=.034) and grade ≥3 gastrointestinal toxicities (4.5% vs 27.3%, P=.047) than did patients receiving WP-CRT and had less chronic gastrointestinal toxicity (13.6% vs 50%, P=.011). Conclusion: WP-IMRT is associated with significantly less toxicity compared with WP-CRT and has a comparable clinical outcome. Further studies with larger sample sizes and longer follow-up times are warranted to justify

    Former meta-analyses have shown a survival benefit for the addition of chemotherapy (CHX) to radiotherapy (RT) and to some extent also for the use of hyperfractionated radiation therapy (HFRT) and accelerated radiation therapy (AFRT) in locally advanced squamous cell carcinoma (SCC) of the head and neck. However, the publication of new studies and the fact that many older studies that were included in these former meta-analyses used obsolete radiation doses, CHX schedules or study designs prompted us to carry out a new analysis using strict inclusion criteria. Randomised trials testing curatively intended RT (≥60 Gy in >4 weeks/>50 Gy in <4 weeks) on SCC of the oral cavity, oropharynx, hypopharynx, and larynx published as full paper or in abstract form between 1975 and 2003 were eligible. Trials comparing RT alone with concurrent or alternating chemoradiation (5-fluorouracil (5-FU), cisplatin, carboplatin, mitomycin C) were analyzed according to the employed radiation schedule and the used CHX regimen. Studies comparing conventionally fractionated radiotherapy (CFRT) with either HFRT or AFRT without CHX were separately examined. End point of the meta-analysis was overall survival. Thirty-two trials with a total of 10 225 patients were included into the meta-analysis. An overall survival benefit of 12.0 months was observed for the addition of simultaneous CHX to either CFRT or HFRT/AFRT (p < 0.001). Separate analyses by cytostatic drug indicate a prolongation of survival of 24.0 months, 16.8 months, 6.7 months, and 4.0 months, respectively, for the simultaneous administration of 5-FU, cisplatin-based, carboplatin-based, and mitomycin C-based CHX to RT (each p < 0.01). Whereas no significant gain in overall survival was observed for AFRT in comparison to CFRT, a substantial prolongation of median survival (14.2 months, p < 0.001) was seen for HFRT compared to CFRT (both without CHX). RT combined with simultaneous 5-FU, cisplatin, carboplatin, and mitomycin C as

    To evaluate the prognostic value of {sup 18}F-FDG PET-CT performed in the third week (iPET) of definitive radiation therapy (RT) in patients with newly diagnosed locally advanced mucosal primary head and neck squamous-cell-carcinoma (MPHNSCC). Seventy-two patients with MPHNSCC treated with radical RT underwent staging PET-CT and iPET. The maximum standardised uptake value (SUV{sub max}), metabolic tumour volume (MTV) and total lesional glycolysis (TLG) of primary tumour (PT) and index node (IN) [defined as lymph node(s) with highest TLG] were analysed, and results were correlated with loco-regional recurrence-free survival (LRFS), disease-free survival (DFS), metastatic failure-free survival(MFFS) and overall survival (OS), using Kaplan-Meier analysis. Optimal cutoffs (OC) were derived from receiver operating characteristic curves: SUV{sub max-PT} = 4.25 g/mL, MTV{sub PT} = 3.3 cm{sup 3}, TLG{sub PT} = 9.4 g, for PT, and SUV{sub max-IN} = 4.05 g/mL, MTV{sub IN} = 1.85 cm{sup 3} and TLG{sub IN} = 7.95 g for IN. Low metabolic values in iPET for PT below OC were associated with statistically significant better LRFS and DFS. TLG was the best predictor of outcome with 2-year LRFS of 92.7 % vs. 71.1 % [p = 0.005, compared with SUV{sub max} (p = 0.03) and MTV (p = 0.022)], DFS of 85.9 % vs. 60.8 % [p = 0.005, compared with SUV{sub max} (p = 0.025) and MTV (p = 0.018)], MFFS of 85.9 % vs. 83.7 % [p = 0.488, compared with SUV{sub max} (p = 0.52) and MTV (p = 0.436)], and OS of 81.1 % vs. 75.0 % [p = 0.279, compared with SUV{sub max} (p = 0.345) and MTV (p = 0.512)]. There were no significant associations between the percentage reduction of primary tumour metabolic parameters and outcomes. In patients with nodal disease, metabolic parameters below OC (for both PT and IN) were significantly associated with all oncological outcomes, while TLG was again the best predictor: LRFS of 84.0 % vs. 55.3 % (p = 0.017), DFS of 79.4 % vs. 38.6 % (p = 0.001), MFFS 86.4 % vs. 68.2 % (p = 0

    There is a clinical need to improve outcomes for patients with locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN), especially in Human Papilloma Virus (HPV) negative and HPV positive subtypes with a significant history of tobacco use. In animal models bearing SCCHN, Cabazitaxel showed an excellent response rate compared to docetaxel and might prove useful in treatment of patients. The primary objective of this study was to determine the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of cabazitaxel when combined with cisplatin and 5-fluorouracil (PF) in induction chemotherapy (IC) for patients with SCCHN. Cabazitaxel-PF IC administered in 3 cycles (each 21 days) followed by concurrent chemoradiation (CRT) or surgery has been evaluated to assess overall response rate (ORR) and progression-free survival (PFS) in this population. This phase I study employed a standard 3+3 design. DLT was defined as grade 4 or 5 toxicity or grade 3 toxicity lasting >7days. Out of 40 consented patients with stage IV, curable, previously untreated, LA-SCHHN and poor prognosis, 35 (32M, 3F) were enrolled and evaluated for toxicity: 19 oropharynx, 10 larynx, 2 oral cancer, 1 nasopharynx and 3 hypopharynx. Five dose levels of cabazitaxel (10, 12.5, 15, 17.5 and 20mg/m 2 ) were tested in combination with cisplatin 100mg/m 2 and 5-fluorouracil (5-FU) 800mg/m 2 /d×4days. Dose escalation for cabazitaxel was terminated upon the occurrences of 2 DLTs and the establishment of MTD. Cabazitaxel was then further escalated with cisplatin 75mg/m 2 and 5-FU 800mg/m 2 /d×4days in the subsequent 3 dose levels (17.5, 20 and 22.5mg/m 2 ). In the expansion cohort, 9 patients were enrolled at the 22.5mg/m 2 dose level. Following 3 cycles of IC, patients were evaluated for clinical, radiographic, and pathologic response to cabazitaxel-PF before beginning CRT or surgery. There were two DLTs (grade 4 hyperuricemia; neutropenic fever, sepsis, and grade 4 thrombocytopenia

    The prognosis of locally advanced cervix cancers is poor with metastatic and local recurrence risks. Recent publications reported that concurrent chemotherapy and pelvic radiation increased local control compared to radiotherapy alone. Chemotherapy could also decrease metastatic recurrences. We report 92 cases of patients with locally advanced cervix cancer treated between 1986 and 1998 at the Institut Curie. Patients and methods. - Concurrent chemo-radiation was exclusive in 51 cases and added to surgery in 41 cases. Chemotherapy with 5FU -Cisplatin-Mitomycin C-Vindesin (protocol A) was performed for 43% of patients and 57% of them received 5FU-Cisplatin alone (protocol B). Results. -Median follow-up was 64 months (6-149 months). Five-year disease-free survival rate was 47% and local control rate was 70%. Disease-free survival was correlated with therapeutic response. After exclusive chemo-radiation, the good responsive patients had a better DFS (54% vs 26%, p=0.018). In the surgery group, those patients with sterilized lymph nodes and tumours had also a higher DFS (76% vs 47%, p=0.036). Toxicity was higher with protocol A. Conclusion. - From our study, it appears that local control of advanced cervix cancers is better with combined chemoradiotherapy but disease-free survival stays low according to the metastatic evolution. Metastasis without local recurrence remained frequent in our study. 5FU-CDDP chemotherapy has a lower toxicity and is as effective as 5FU-CDDP-Mitomycin C-Vindesin protocol, in association with radiotherapy.

    Purpose: Local recurrence is a significant problem following primary surgery for advanced vulva carcinoma. The objectives of this study were to evaluate the impact of adjuvant vulvar radiation on local control in high risk patients and the impact of local recurrence on overall survival. Methods and Materials: From 1980-1994, 62 patients with invasive vulva carcinoma and either positive or close (less 8 mm) margins of excision were retrospectively studied. Thirty-one patients were treated with adjuvant radiation therapy to the vulva and 31 patients were observed after surgery. Kaplan-Meier estimates and the Cox proportional hazard regression model were used to evaluate the effect of adjuvant radiation therapy on local recurrence and overall survival. Independent prognostic factors for local recurrence and survival were also assessed. Results: Local recurrence occurred in 58% of observed patients and 16% in patients treated with adjuvant radiation therapy. Adjuvant radiation therapy significantly reduced local recurrence rates in both the close margin and positive margin groups (p = 0.036, p = 0.0048). On both univariate and multivariate analysis adjuvant radiation and margins of excision were significant prognostic predictors for local control. Significant determinants of actuarial survival included International Federation of Gynecologists and Obstetricians (FIGO) stage, percentage of pathologically positive inguinal nodes and margins of excision. The positive margin observed group had a significantly poorer actuarial 5 year survival than the other groups (p = 0.0016) and adjuvant radiation significantly improved survival for this group. The 2 year actuarial survival after developing local recurrence was 25%. Local recurrence was a significant predictor for death from vulva carcinoma (risk ratio 3.54). Conclusion: Local recurrence is a common occurrence in high risk patients. In this study adjuvant radiation therapy significantly reduced local recurrence rates and

    To investigate the potential prognostic role of tumor cell podoplanin expression in patients treated with resection followed by irradiation or chemoradiotherapy for locally advanced squamous cell carcinoma of the head and neck (SCCHN). Podoplanin expression (≤10 % versus > 10 %) and 12 other factors were evaluated in 160 patients for their association with locoregional control (LRC), metastases-free (MFS) and overall survival (OS). Other factors were age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, preradiotherapy (pre-RT) hemoglobin level, tumor site, histological grading, T category, N category, American Joint Committee on Cancer (AJCC) stage, human papillomavirus (HPV) status, extent of resection and concurrent chemotherapy. In multivariate analysis, ECOG performance status 0-1 (risk ratio, RR: 3.01; 95 % confidence interval, CI: 1.42-7.14; p = 0.003), pre-RT hemoglobin levels ≥ 7.45 mmol/l (12 g/dl; RR: 2.03; 95 % CI: 1.04-3.94; p = 0.038), oropharyngeal cancer (RR: 1.25; 95 % CI: 1.01-1.55; p = 0.038) and T category T1-2 (RR: 1.81; 95 % CI: 1.24-2.79; p = 0.002) were significantly associated with improved LRC. T category T1-2 (RR: 1.90; 95 % CI: 1.25-3.06; p = 0.002) and N category N0-2a (RR: 5.22; 95 % CI: 1.96-18.09; p < 0.001) were significantly associated with better MFS. Pre-RT hemoglobin levels ≥ 7.45 mmol/l (RR: 2.44; 95 % CI: 1.27-4.74; p = 0.007), T category T1-2 (RR: 1.97; 95 % CI: 1.36-3.04; p < 0.001) and N category N0-2a (RR: 2.87; 95 % CI: 1.37-6.61; p = 0.005) were significantly associated with improved OS. Podoplanin expression ≤ 10 % showed a trend towards improved OS on both univariate (p = 0.050) and multivariate analysis (RR: 1.86; 95 % CI: 0.96-3.59; p = 0.07). Treatment outcomes were significantly associated with performance status, pre-RT hemoglobin level, tumor site and tumor stage. Tumor cell expression of podoplanin ≤ 10 % showed a trend towards improved OS when compared to podoplanin expression of

Multidisciplinary treatment, consisting of surgery, radioiodine, external irradiation and TSH suppression was studied. We emphasized that radioiodine treatment after thyroid-ectomy was unique and an ideal therapeutic model for locally advanced, distant metastatic and recurrent cases as far as radioiodine was accumulated on thyroid cancer tissue. External irradiation was sometimes effective for the remnant thyroid carcinoma and metastases. Occassionally, well-differentiated thyroid carcinoma showed good response to TSH suppression therapy using thyroid hormone. The significance of conversion of well-differentiated carcinoma of thyroid to anaplastic carcinoma was noticed. We recognized that radiation therapy was effective for advanced well-differentiated thyroid carcinoma in multidisciplinary treatment. (author)

    One hundred twenty-nine patients with far advanced or recurrent gastric carcinoma underwent computed tomography (CT) of the abdomen. There were three histologic types: differentiated (n=41), undifferentiated (n=68), and unclassified (n=20). Eighteen patients who had developed obstructive jaundice were retrospectively studied to elucidate the nature of obstruction with histologic correlation. In differentiated carcinomas tumor tended to grow in an expansive fashion. A fairly large, well-defined lymph adenopathy was observed on CT. The extrahepatic bile duct surrounded by lymph nodes appeared as ''doughnot sign'' in six of eight patients. Undifferentiated gastric carcinoma had tendency to extend infiltratively. Bile duct obstruction was only a part of diffuse spreading. In spite of the presence of obstructive jaundice, no discrete mass was demonstrated around the extrahepatic bile duct on CT. In none of nine patients was present ''doughnot sign''. The significance of lymph node dissection along the extrahepatic bile duct in patients with differentiated gastric carcinoma was emphasized. The region of hepatoduodenal and pancreatico-duodenal lymph nodes should be carefully evaluated in interpretation of abdominal CT. (author)

    Purpose: To test the hypothesis that daily intravenous pre-hydration decreases renal toxicity and improves chemotherapy adherence in patients receiving daily cisplatin to concurrent radiotherapy for locally advanced non-small cell lung cancer (NSCLC). Patients and methods: Patients with locally advanced NSCLC were treated between 2008 and August 2012 with daily 6 mg/m 2 cisplatin as a bolus injection in 10 ml; of saline and 66 Gy/24 fr radiotherapy in 32 days. Since January 2011, the administration of cisplatin was routinely preceded by intravenous pre-hydration with 1 L of natriumchloride 0.9%. Patients were divided in a pre-hydrated (PH) and non-pre-hydrated (NPH) cohort. Serum-creatinine and glomerular filtration rate (GFR) were assessed twice weekly during treatment. Retrospectively, baseline data, toxicity, treatment adherence and efficacy data were compared. Results: Of the 356 patients 232 NPH patients and 100 PH patients were eligible. Patient-and treatment characteristics compared equally. The median of the maximum decrease in GFR was 24% and 8% for NPH and PH (p < 0.01), respectively. Sixty-nine percent of the patients in the NPH group completed the 24 administrations of cisplatin, as compared to 83% of the PH group (p < 0.01). Nineteen percent vs. 2% of the patients in the NPH and PH group discontinued cisplatin treatment because of renal toxicity. Surprisingly, the incidence of acute esophageal toxicity grade ⩾2 decreased following prehydration: 62% vs. 34% (p < 0.001) for the NPH and PH groups, respectively. The one-year survival was comparable between groups (75% for NPH and 71% for PH). Conclusion: Daily pre-hydration was associated with a reduced rate of both renal and acute esophageal toxicity and an increased chemotherapy adherence in patients receiving daily dose of cisplatin and concurrent radiotherapy for locally advanced NSCLC

    Full Text Available Hepatocellular carcinoma (HCC is an intrinsically chemotherapy refractory malignancy. Development of effective therapeutic regimens would be facilitated by improved preclinical HCC models. Currently, most models consist of subcutaneous human tumor transplants in immunodeficient mice; however, these do not reproduce the extensive liver disease associated with HCC or metastasize. To address this deficiency, we developed an orthotopic model. Human HCC cells were transfected with the gene encoding secretable β-subunit human choriogonadotropin (β-hCG, which was used as a surrogate marker of tumor burden. The HCC cells were implanted into the left liver lobe of severe combined immunodeficient (SCID mice, after which the efficacy of different therapies was evaluated on established, but liver-confined human Hep3B cell line HCC. Treatments included sorafenib or metronomic chemotherapy using cyclophosphamide (CTX, UFT, an oral 5-fluorouracil prodrug, or doxorubicin either alone or in various combinations, with or without an antiangiogenic agent, DC101, an anti-vascular endothelial growth factor receptor-2 antibody. Sorafenib inhibited tumor growth in a dose-dependent manner but caused severe weight loss in SCID mice, thus necessitating use of DC101 in subsequent experiments. Although less toxicity was observed using either single or doublet metronomic chemotherapy without any added antiangiogenic agent, none, provided survival benefit. In contrast, significantly improved overall survival was observed using various combinations of metronomic chemotherapy regimens such as UFT + CTX with DC101. In conclusion, using this model of liver-confined but advanced HCC suggests that the efficacy of a targeted antiangiogenic drug or metronomic chemotherapy can be mutually enhanced by concurrent combination treatment.

    Smoking and betel nut chewing are well-known risk factors for head and neck squamous cell carcinoma (HNSCC). Smoking is also a strong prognosticator for patients with locally advanced HNSCC receiving induction chemotherapy. Smoking with or without betel nut chewing is a common practice in Asia. However, little is known regarding whether betel nut chewing can serve as a prognostic factor for smoking patients with locally advanced HNSCC receiving induction chemotherapy. The aim of this study was to evaluate the prognostic impact of betel nut chewing in such patients receiving induction chemotherapy with docetaxel, cisplatin, and fluorouracil (TPF). From January 2010 to December 2012, we retrospectively analyzed 162 smoking patients with locally advanced HNSCC who received induction chemotherapy with TPF at our institution. Background characteristics, including a history of betel nut chewing, were analyzed as potential prognostic factors. Among the 162 smoking patients, 131 patients (81%) were betel nut chewers, while 31 (19%) were non-betel nut chewers. One hundred fifty-six (96%) were men, and 6 (4%) were women. The median age was 53 years. The overall response rates to induction chemotherapy were 57 and 77% in patients with and without betel nut chewing history, respectively (P = 0.038). The 2-year progression survival rates were 37 and 67% in patients with and without betel nut chewing history, respectively (P = 0.004). The 2-year overall survival rates were 47 and 71% in patients with and without betel nut chewing history, respectively (P = 0.017). Betel nut chewing history was independently associated with a poor response to induction chemotherapy, an inferior progression-free survival rate, and a poor overall survival rate. Our results indicate that betel nut chewing history is independently associated with poor prognosis in smoking patients with locally advanced HNSCC receiving induction chemotherapy with TPF. Further investigation is warranted to

    The purpose of this study was to create a prognostic model for distant metastasis in patients with locally advanced NPC who accept concurrent chemotherapy combined with intensity-modulated radiotherapy (CCRT) to identify high-risk patients who may benefit from neoadjuvant chemotherapy (NACT). A total of 881 patients with newly-diagnosed, non-disseminated, biopsy-proven locoregionally advanced NPC were retrospectively reviewed; 411 (46.7%) accepted CCRT and 470 (53.3%) accepted NACT followed by CCRT. Multivariate analysis demonstrated N2-3 disease, plasma Epstein-Barr virus (EBV) DNA > 4000 copies/mL, serum albumin ≤ 46 g/L and platelet count >300 k/cc were independent prognostic factors for distant metastasis in the CCRT group. Using these four factors, a prognostic model was developed, as follows: 1) low-risk group: 0-1 risk factors; and 2) high-risk group: 2-4 risk factors. In the high-risk group, patients who accepted NACT + CCRT had significantly higher distant metastasis-free survival and progression-free survival rates than the CCRT group (P = 0.001; P = 0.011). This simple prognostic model for distant metastasis in locoregionally advanced NPC may facilitate with the selection of high-risk patients who may benefit from NACT prior to CCRT.

    This phase I study investigates the feasibility of carboplatin plus dose-dense (q2-week) pemetrexed given concurrently with radiotherapy (XRT) for locally advanced and oligometastatic non-small cell lung cancer (NSCLC). Eligible patients had Stage III or IV (oligometastatic) NSCLC. Patients received XRT to 63 Gy in standard fractionation. Patients received concurrent carboplatin (AUC = 6) during weeks 1 and 5 of XRT, and pemetrexed during weeks 1, 3, 5, and 7 of XRT. The starting dose level (level 1) of pemetrexed was 300 mg/m 2 . Following the finding of dose limiting toxicity (DLT) in dose level 1, an amended dose level (level 1A) continued pemetrexed at 300 mg/m 2 , but with involved field radiation instead of extended nodal irradiation. Consolidation consisted of carboplatin (AUC = 6) and pemetrexed (500 mg/m 2 ) q3 weeks × 2 -3 cycles. Eighteen patients were enrolled. Fourteen patients are evaluable for toxicity analysis. Of the initial 6 patients treated on dose level 1, two experienced DLTs (one grade 4 sepsis, one prolonged grade 3 esophagitis). There was one DLT (grade 5 pneumonitis) in the 8 patients treated on dose level 1A. In 16 patients evaluable for response (4 with oligometastatic stage IV disease and 12 with stage III disease), the median follow-up time is 17.8 months. Thirteen of 16 patients had in field local regional response. The actuarial median survival time was 28.6 months in all patients and 34.7 months (estimated) in stage III patients. Concurrent carboplatin with dose-dense (q2week) pemetrexed at 300 mg/m 2 with involved field XRT is feasible and encouraging in patients with locally advanced and oligometastatic NSCLC.

    Purpose/Objective: To determine the efficacy of Mitomycin C (MC) in combination with radiotherapy (RT) for the treatment of carcinoma of the cervix Materials and Methods: A Phase III randomized study of MC + RT (CMT) vs. RT was initiated in 1990 to test whether or not a bioreductive alkylating agent would improve the cure of squamous cell carcinoma of the cervix (CCa), a tumor for which hypoxia is known to be a strong prognostic factor. As of March 1996, 157 patients have been enrolled. After excluding 8 patients (pts) for protocol violations (3 in CMT group and 5 in RT group), the 110 analyzable pts having at least two years of partial follow-up were used for the preliminary analysis reported here. Intravenous MC, 15 mg/M 2 , was given on the 1st and 6th week of treatment. Before randomization between CMT and RT, patients were stratified by standardized radiotherapy prescriptions of both brachytherapy and external beam RT dose, as dictated by tumor stage. Results: The 58 pts in the CMT group and 52 pts in the RT group have a mean follow-up of 27.1 months, and a comparable distribution by age and stage (mean age 48.3 years; stage IB 2%, IIA 14%, IIB 47%, IIIA 1%, IIIB 34%, IVA 3%). The three year actuarial survival rates for CMT and RT were 77% and 58%, respectively (p=0.15). Three months following completion of therapy, complete response (CR) was achieved in 51 pts (88%) of the CMT group and in 47 pts (90%) of the RT group (p=NS). Of those with CR, the three year actuarial local recurrence free survivals for CMT and RT were 84% and 68%, respectively (p=0.12). There were no treatment-related deaths. Mild hematologic toxicity was seen only in the CMT group, with 4 pts having a nadir WBC <1.5 (but none below 1.0) and with 1 pt having a nadir platelet count below 25K. Grade 3 skin toxicity was seen in 3 pts receiving CMT and 1 pt receiving RT alone. Grade 3 cystitis was seen in one RT pt. Grade 3 and 4 GI toxicities were seen in two RT pts. No excess in non

    Purpose: Patients with advanced stage IIIB or stage IV non-small cell lung carcinoma are typically treated with initial platinum-based chemotherapy. A variety of factors (eg, performance status, gender, age, histology, weight loss, and smoking history) are generally accepted as predictors of overall survival. Because uncontrolled pulmonary disease constitutes a major cause of death in these patients, we hypothesized that clinical and radiographic factors related to intrathoracic disease at diagnosis may be prognostically significant in addition to conventional factors. The results have implications regarding the selection of patients for whom palliative thoracic radiation therapy may be of most benefit. Methods and Materials: We conducted a pooled analysis of 189 patients enrolled at a single institution into 9 prospective phase II and III clinical trials involving first-line, platinum-based chemotherapy. Baseline clinical and radiographic characteristics before trial enrollment were analyzed as possible predictors for subsequent overall survival. To assess the relationship between anatomic location and volume of disease within the thorax and its effect on survival, the pre-enrollment computed tomography images were also analyzed by contouring central and peripheral intrapulmonary disease. Results: On univariate survival analysis, multiple pulmonary-related factors were significantly associated with worse overall survival, including pulmonary symptoms at presentation (P=.0046), total volume of intrathoracic disease (P=.0006), and evidence of obstruction of major bronchi or vessels on prechemotherapy computed tomography (P<.0001). When partitioned into central and peripheral volumes, central (P<.0001) but not peripheral (P=.74) disease was associated with worse survival. On multivariate analysis with known factors, pulmonary symptoms (hazard ratio, 1.46; P=.042), central disease volume (hazard ratio, 1.47; P=.042), and bronchial/vascular compression (hazard ratio, 1

    Sorafenib is the recommended treatment for patients with advanced hepatocellular carcinoma. We aimed to compare the efficacy and safety of sorafenib to that of selective internal radiotherapy (SIRT) with yttrium-90 ( 90 Y) resin microspheres in patients with hepatocellular carcinoma. SARAH was a multicentre, open-label, randomised, controlled, investigator-initiated, phase 3 trial done at 25 centres specialising in liver diseases in France. Patients were eligible if they were aged at least 18 years with a life expectancy greater than 3 months, had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, Child-Pugh liver function class A or B score of 7 or lower, and locally advanced hepatocellular carcinoma (Barcelona Clinic Liver Cancer [BCLC] stage C), or new hepatocellular carcinoma not eligible for surgical resection, liver transplantation, or thermal ablation after a previously cured hepatocellular carcinoma (cured by surgery or thermoablative therapy), or hepatocellular carcinoma with two unsuccessful rounds of transarterial chemoembolisation. Patients were randomly assigned (1:1) by a permutated block method with block sizes two and four to receive continuous oral sorafenib (400 mg twice daily) or SIRT with 90 Y-loaded resin microspheres 2-5 weeks after randomisation. Patients were stratified according to randomising centre, ECOG performance status, previous transarterial chemoembolisation, and presence of macroscopic vascular invasion. The primary endpoint was overall survival. Analyses were done on the intention-to-treat population; safety was assessed in all patients who received at least one dose of sorafenib or underwent at least one of the SIRT work-up exams. This study has been completed and the final results are reported here. The trial is registered with ClinicalTrials.gov, number NCT01482442. Between Dec 5, 2011, and March 12, 2015, 467 patients were randomly assigned; after eight patients withdrew consent, 237 were assigned to

    The aim of the study was to compare clinical outcomes and toxicity between 3D conformal radiotherapy (3DCRT) and image-guided intensity-modulated radiotherapy (IG-IMRT) administered through helical tomotherapy in locally advanced rectal cancer (LARC) patients receiving preoperative chemoradiotherapy. We reviewed 144 patients with Stage II–III rectal cancer receiving preoperative fluoropyrimidine-based chemoradiotherapy followed by radical resection. Tumor responses following chemoradiotherapy were evaluated using the Dworak tumor regression grade (TRG). Of the 144 patients, 45 received IG-IMRT and 99 received 3DCRT. A significant reduction in Grade 3 or 4 acute gastrointestinal toxicity (IG-IMRT, 6.7%; 3DCRT, 15.1%; P = 0.039) was observed by IG-IMRT. The pathologic complete response (pCR) rate did not differ between the IG-IMRT and the 3DCRT group (17.8% vs 15.1%, P = 0.52). Patients in the IG-IMRT group had the trend of favorable tumor regressions (TRG 3 or 4) compared with those in the 3DCRT group (66.7% vs 43.5%, P = 0.071). The median follow-up was 53 months (range, 18–95 months) in the 3DCRT group and 43 months (range, 17–69 months) in the IG-IMRT group. Four-year overall, disease-free, and local failure–free survival rates of the IG-IMRT and 3DCRT groups were 81.6% and 67.9% (P = 0.12), 53.8% and 51.8% (P = 0.51), and 88% and 75.1% (P = 0.031), respectively. LARC patients treated with preoperative IG-IMRT achieved lower acute gastrointestinal adverse effects and a higher local control rate than those treated with 3DCRT, but there was no prominent difference in distant metastasis rate and overall survival between two treatment modalities.

    Purpose: Concurrent cisplatin-based chemoradiotherapy (CRT) is the standard treatment for locally advanced cervical cancer. RTOG 0417 was a Phase II study exploring the safety and efficacy of the addition of bevacizumab to standard CRT. Methods and Materials: Eligible patients with bulky tumors (Stage IB-IIIB) were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiotherapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for three cycles. Treatment-related serious adverse event (SAE) and other adverse event (AE) rates within the first 90 days from treatment start were determined. Treatment-related SAEs were defined as any Grade {>=}4 vaginal bleeding or thrombotic event or Grade {>=}3 arterial event, gastrointestinal (GI) bleeding, or bowel/bladder perforation, or any Grade 5 treatment-related death. Treatment-related AEs included all SAEs and Grade 3 or 4 GI toxicity persisting for >2 weeks despite medical intervention, Grade 4 neutropenia or leukopenia persisting for >7 days, febrile neutropenia, Grade 3 or 4 other hematologic toxicity, and Grade 3 or 4 GI, renal, cardiac, pulmonary, hepatic, or neurologic AEs. All AEs were scored using the National Cancer Institute Common Terminology Criteria (CTCAE) v 3.0 (MedDRA version 6.0). Results: A total of 60 patients from 28 institutions were enrolled between 2006 and 2009, and of these, 49 patients were evaluable. The median follow-up was 12.4 months (range, 4.6-31.4 months).The median age was 45 years (range, 22-80 years). Most patients had FIGO Stage IIB (63%) and were of Zubrod performance status of 0 (67%). 80% of cases were squamous. There were no treatment-related SAEs.

    Full Text Available Abstract Background Thymostimulin is a thymic peptide fraction with immune-mediated cytotoxicity against hepatocellular carcinoma in vitro. In a phase II trial, we investigated safety and efficacy including selection criteria for best response in advanced or metastasised hepatocellular carcinoma. Methods 44 patients (84 % male, median age 69 years not suitable or refractory to conventional therapy received thymostimulin 75 mg subcutaneously five times per week for a median of 8.2 months until progression or complete response. 3/44 patients were secondarily accessible to local ablation or chemoembolisation. Primary endpoint was overall survival, secondary endpoint tumor response or progression-free survival. A multivariate Cox's regression model was used to identify variables affecting survival. Results Median survival was 11.5 months (95% CI 7.9–15.0 with a 1-, 2- and 3-year survival of 50%, 23% and 9%. In the univariate analysis, a low Child-Pugh-score (p = 0.01, a low score in the Okuda- and CLIP-classification (p Conclusion Outcome in our study rather depended on liver function and intrahepatic tumor growth (presence of liver cirrhosis and Okuda stage in addition to response to thymostimulin, while an invasive HCC phenotype had no influence in the multivariate analysis.

    Purpose: To compare, in a retrospective study, the toxicity and efficacy of simultaneous integrated boost using intensity-modulated radiotherapy (IMRT) vs. conventional radiotherapy (CRT) in patients treated with concomitant carboplatin and 5-fluorouracil for locally advanced oropharyngeal cancer. Methods and Materials: Between January 2000 and December 2007, 249 patients were treated with definitive chemoradiation. One hundred patients had 70 Gy in 33 fractions using IMRT, and 149 received CRT at 70 Gy in 35 fractions. Overall survival, disease-free survival, and locoregional control were estimated using the Kaplan-Meier method. Results: Median follow-up was 42 months. Three-year actuarial rates for locoregional control, disease-free survival, and overall survival were 95.1% vs. 84.4% (p = 0.005), 85.3% vs. 69.3% (p = 0.001), and 92.1% vs. 75.2% (p < 0.001) for IMRT and CRT, respectively. The benefit of the radiotherapy regimen on outcomes was also observed with a Cox multivariate analysis. Intensity-modulated radiotherapy was associated with less acute dermatitis and less xerostomia at 6, 12, 24, and 36 months. Conclusions: This study suggests that simultaneous integrated boost using IMRT is associated with favorable locoregional control and survival rates with less xerostomia and acute dermatitis than CRT when both are given concurrently with chemotherapy.

    Concomitant radiotherapy (5FU -MMC) was proved to be useful in locally advanced anal canal carcinoma. Nevertheless. it remains 30 % of failures after this conservative treatment. The tolerance and efficiency of a neo-adjuvant chemotherapy (5-FU-CDDP) were validated by a phase II trial including 80 patients, which obtained 73 % of colostomy free survival and 70 % of relapse free survival at 3-year follow-up. its usefulness is studied in an ongoing phase III trial, as well as the dose escalation of the boost, from 15 Gy to 25-25 Gy. The results of the 101 first included patients are studied by an intermediate analyze. In July 2003, 222 patients were enrolled by 33 investigating centres out of the 350 planned patients until the end of the trial in December 2004. (author)

    Objective: To compare the long-term efficacy between two radiochemotherapy regimens for locally advanced nasopharyngeal carcinoma (NPC): intensity-modulated radiotherapy with concurrent chemotherapy (CCRT) versus neoadjuvant chemotherapy (NACT) followed by CCRT. Methods: A retrospective analysis was performed on the clinical data of 278 patients with locally advanced NPC who were admitted to our hospital from 2001 to 2008. Of the 278 patients, 133 received CCRT, and 145 received NACT followed by CCRT (NACT + CCRT). Results: The follow-up rate was 96.6%. The 5-year overall survival (OS),distant metastasis-free survival (DMFS), recurrence-free survival (RFS), and progression-free survival (PFS) were 78.1%, 78.0%, 90.6%, and 72.0%, respectively. There were no significant differences between the CCRT group and NACT + CCRT group in 5-year OS (79.9% vs. 76.4%, P=0.443), DMFS (77.1% vs. 78.9%, P=0.972), RFS (91.6% vs. 89.8%, P=0.475), and PFS (71.6% vs. 72.2%, P=0.731). Subgroup analysis showed that compared with CCRT, NACT + CCRT did not significantly improve 5-year RFS in T 3-4 N 0-1 patients (90.7% vs. 86.9%, P=0.376) and did not significantly improve 5-year DMFS in patients with advanced N-stage disease (57.6% vs. 69.7%, P=0.275). There were significantly higher numbers of individuals with neutropenia,decrease in hemoglobin, and upper gastrointestinal reactions in patients treated with NACT + CCRT than in those treated with CCRT (100 vs. 52, P=0.000; 64 vs. 35, P=0.010; 90 vs. 63, P=0.044). Conclusions: Compared with CCRT,NACT + CCRT does not significantly improve the prognosis in patients with locally advanced NPC and leads to significant increases in grade ≥ 3 toxicities (neutropenia, decrease in hemoglobin, and upper gastrointestinal reactions). The role of NACT in the treatment of locally advanced NPC needs further study. (authors)

    Purpose: To study the treatment outcome in patients with locally recurrent nasopharyngeal carcinoma (NPC) who were treated with stereotactic radiotherapy (SRT). Methods and Materials: Thirty patients with non-metastatic, locally recurrent NPC who were treated with curative intent between 1998 and 2002 were retrospectively analyzed. The International Union Against Cancer T-stage distribution at recurrence (rT) was as follows: rT1-14, rT2-7, rT3-3, and rT4-6. All patients were treated with SRT with a daily fractional dose of 2.5-4.5 Gy (median, 3 Gy) in 8-22 fractions (median, 18 fractions). Total equivalent dose (TED) was calculated by the linear-quadratic formula without a time factor correction. Results: The 5-year actuarial overall survival rate, disease-specific survival rate, and local failure-free survival (LFFS) rate for the whole group were 40%, 41.4%, and 56.8%, respectively. The 3-year LFFS rates of rT1-2 and rT3-4 diseases were 65% and 66.7%, respectively. Seven of nine patients who received a TED <55 Gy recurred locally compared with 4 of 21 patients who received ≥55 Gy. Their corresponding 5-year LFFS rates were 22.2% and 75.8% (p = 0.005). The TED was the only factor significant in affecting the local control on univariate analyses. Conclusion: SRT is an effective treatment for locally recurrent NPC. TED ≥55 Gy should be given to secure a higher local control rate. The late complication rates were acceptable for patients with rT1-2 disease. For patients with rT3-4 disease, more works need to be done to further decrease the late complications.

    Introduction: Nasopharyngeal carcinoma (NPC) tops the list of malignancy in Malaysia and ranks first in male malignancy in the state of Sarawak. The majority of the NPC patients presented in the advanced stages and often with distal metastasis usually to the bones. In our local hospital is the new practice of bone scan using Tc99 started last year. Over a period of 9 months from July 2003 to March 2004, 41 NPC patients had the bone scans and our experience in these are reviewed and presented. Method: The NPC patients are selected consecutively including both new and treated patients. The scanner used is Siemen E.cam plus and Technecium (Tc99) the radio-active isotope used. The scan images are read and reported by qualified and trained Radiologists. The bone scans are requested from the ENT Specialist of the ENT department of the Hospital. The bone scan reports are checked by the ENT Specialists and the decisions made as to clinical correlation and further definitive imaging studies. Results: 41 NPC patients were included in the studies, 29 newly diagnosed and bone-canned before treatment started and 12 treated of which 3 being diagnosed having recurrent NPC. Of the 29 newly diagnosed patients, one was found true positive bone scan having increased radio-tracer uptake and confirmed Xray imagings. 3 of the treated patients had true positive bone scan with increased radio-tracer uptake and confirmed Xray imagings. Hence a total of 4 out of the 41 patients (9.8%) had bone metastasis on positive bone scans. Of the 29 newly diagnosed patients, 14 were found false positive bone scan having increased radio-tracer uptake but no confirmed X ray imagings. 4 of the treated patients had false positive bone scan with increased radio-tracer uptake but no confirmed X ray imagings. Hence a total of 18 out of the 41 patients (44%) had no bone metastasis on positive bone scans. There were 6 patients with symptoms referable to the bones' distal to the head and 2 had true positive bone

    The combination of radiotherapy and surgery in the treatment of advanced oral carcinoma (T3 and T4 lesions) yields good possibilities of recovery; whether radiotherapy should be given before or after surgery is still debated. Fifty patients with advanced oral carcinomas were analyzed: 24 of them were irradiated before and 26 after surgery; doses ranged from 40 to 56 Gy for the first group of patients, and from 50 to 68 Gy for the second one. The disease-free survival 48 months after the diagnosis was 36% in patients who received preoperative irradiation, and 53.6% in patients who received postoperative radiotherapy. the latter allowed local control of the disease to be significantly improved (χ 2 3.99, 0.01< p<0.05). The quality of survival was worse in the group receiving preoperative irradiation, because of radiation-induced surgical complications, which were especially observed in patients with diffuse disease. The findings suggest that postoperative radiotherapy may be advisable if the tumor is resectable, since tolerance and local control rate were acceptable. On the contrary, nearly inoperable masses and massive neck diseases often require preoperative irradiation

    From 1974 to 1984, 442 consecutive patients with carcinoma of the uterine cervix were referred for combined intracavitary (IRT) and external radiotherapy (ERT). Dose prescriptions were performed based on the points A and B of the Manchester system. From 1978 the treatment strategy was changed from continuous (CRT) to split course radiotherapy (SCRT) with a higher total dose to point B, a lower dose to point A from the IRT, and a longer total treatment time (TTT). The purpose of the present thesis is: To evaluate local tumour control, distant metastases, survival and complications in the rectosigmoid and bladder in relation to treatment strategy (continuous and split course radiotherapy). To evaluate prognostic factors and importance of treatment strategy for local control, distant metastases, and survival by uni- and multivariate analyses. To develop a classification system (AADK, Aarhus, Denmark) for the recording of early and late radiation complications allowing and estimation of the importance of latency when reporting late radiotherapeutic morbidity and a rescoring of complication grade, and to compare results from AADK with those from the French-Italian glossary recording the maximal damage. To evaluate early and late radiotherapeutic morbidity and the importance of latency by comparing frequencies and actuarial estimates of late complications, to estimate the combined late organ morbidity and the probability of being alive, cured and without serious complications.

    Full text: Introduction: The majority of thyroid cancers have a slow evolution, a more often loco-regional extension, and a good forecast. Remote metastases, when they exist, generally touch the osseous skeleton and/or pulmonary tissue. However, unusual metastatic localizations much more exceptional are possible. The authors report through these work five cases of atypical metastasis of differentiated thyroid carcinoma followed in Nuclear Medicine department of Ibn Sina hospital in Rabat under the directives of Professor N Ben Rais. Materials and methods: Our five patients had initially undergone a total thyroidectomy for differentiated thyroid carcinoma histologically confirmed. They had profited 4 weeks after the surgical gesture from a reference isotopic exploration (131 Iodine whole body scan and thyroglobulin dosage). The paraclinic assessment was supplemented by a computed tomography (CT). Results: Revealing symptomatology in the first 69 year old patient was dominated by blindness associated with an elective up-take of radioactive 131-Iodine on the level of hypophyseal gland extending to the sphenoid bone. The second 55 year old patient reported right basithoracic pains resisting to the usual antalgic treatment with a bulky mass driving back the kidney right to the bottom at CT with and important up-take 131-Iodine at whole body scan; a surrenalectomy was thus carried out with conservation of the kidney. The three other patients presented at the clinical examination dermohypodermic nodular lesions of various localizations whose anatomopathologic study had confirmed their thyroid metastatic origin. In the 5 patients the rate of thyroglobulin was considerably high. An activity of 3,7 GBq 131-Iodine was managed with the 5 patients. The evolution was marked, in the short run, at the first patient by a recovery partial of the sight, the disappearance of pain in the second patient and a remarkable reduction of thyroglobulin level for all our patients.

    Patients with locally advanced SCCHN have a poor prognosis. This study investigated the prognostic value of the tumor cell expression of the fibroblast growth factor 2 (FGF-2) in patients treated with surgery followed by radiotherapy. The impact of FGF-2-expression and 11 additional potential prognostic factors on loco-regional control (LRC), metastases-free survival (MFS), and overall survival (OS) was retrospectively evaluated in 146 patients. Additional factors included age, gender, performance status, pre-radiotherapy hemoglobin levels, tumor site, histologic grade, T-category, N-category, human papilloma virus (HPV) status, extent of resection, and chemotherapy. Univariate analyses were performed with the Kaplan-Meier method and the log-rank test, multivariate analyses with the Cox proportional hazard model. On multivariate analysis, improved LRC was significantly associated with FGF-2-negativity [risk ratio (RR): 7.33; 95 %-confidence interval (CI): 2.88-19.05; p < 0.001], lower T-category (RR: 2.42; 95 %-CI: 1.47-4.33; p < 0.001), lower N-category (RR: 12.36; 95 %-CI: 3.48-78.91; p < 0.001), and pre-radiotherapy hemoglobin levels ≥12 g/dl (RR: 4.18; 95 %-CI: 1.73-10.53; p = 0.002). No factor was significantly associated with improved MFS. Lower T-category showed a trend (RR: 1.59; 95 %-CI: 0.97-2.82; p = 0.069). Better OS was significantly associated with FGF-2-negativity (RR: 5.10; 2.22-11.80; p < 0.001), lower T-category (RR: 2.17; 95 %-CI: 1.38-3.68; p < 0.001), lower N-category (RR: 3.86; 95 %-CI: 1.60-10.85; p = 0.002), and pre-radiotherapy hemoglobin levels ≥12 g/dl (RR: 3.20; 95 %-CI: 1.46-7.30; p = 0.004). HPV-positivity showed a trend (RR: 2.36; 95 %-CI: n.a.; p = 0.054). Tumor cell expression of FGF-2 proved to be an independent prognostic factor for LRC and OS. This factor can help personalize treatment and stratify patients in future trials. (orig.)

    Purpose: Radiation Therapy Oncology Group 0417 was a phase II study that explored the safety and efficacy of the addition of bevacizumab to chemoradiation therapy. The safety results have been previously reported. Herein we report the secondary efficacy endpoints of overall survival (OS), locoregional failure (LRF), para-aortic nodal failure (PAF), distant failure (DF), and disease-free survival (DFS). Methods and Materials: Eligible patients with bulky Stage IB-IIIB disease were treated with once-weekly cisplatin (40 mg/m 2 ) chemotherapy and standard pelvic radiation therapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for 3 cycles during chemoradiation. For OS, failure was defined as death of any cause and was measured from study entry to date of death. LRF was defined as any failure in the pelvis. PAF was defined as any para-aortic nodal failure. DF was analyzed both including and excluding PAF. DFS was measured from study entry to date of first LRF. DF was measured with or without PAF or death. OS and DFS were estimated by the Kaplan-Meier method, and LRF and DF rates were estimated by the cumulative incidence method. Results: 49 eligible patients from 28 institutions were enrolled between 2006 and 2009. The median follow-up time was 3.8 years (range, 0.8-6.0 years). The surviving patients had a median follow-up time of 3.9 years (range, 2.1-6.0 years). Most patients had tumors of International Federation of Gynecology and Obstetrics Stage IIB (63%), and 80% were squamous. The 3-year OS, DFS, and LRF were 81.3% (95% confidence interval [CI], 67.2%-89.8%), 68.7% (95% CI, 53.5%-79.8%), and 23.2% (95% CI, 11%-35.4%), respectively. The PAF, DF without PAF, and DF with PAF at 3 years were 8.4% (95% CI, 0.4%-16.3%), 14.7% (95% CI, 4.5%-24.9%), and 23.1% (95% CI 11.0%-35.2%), respectively. Conclusion: In this study, bevacizumab in combination with standard pelvic chemoradiation therapy for locally advanced cervical cancer

    Merkel cell carcinoma (MCC) is a rarely made but potentially devastating diagnosis. While local disease might be cured by surgery and radiotherapy, advanced disease is usually rapidly progressive and fatal. Until very recently, the only approach to metastatic MCC was cytotoxic chemotherapy with results so disappointing that current treatment guidelines discourage its use and recommend clinical trial as a more viable treatment option. Fortunately, recent advances in the understanding of the molecular pathogenesis of this tumour have produced a wide variety of experimental treatments for MCC, some of which are quite promising. The most current information regarding the diagnosis, staging, management of this tumour is briefly presented as well as new insights into the molecular basis of MCC and therapeutic approaches to MCC.

    Purpose: The purpose of this study was to evaluate local transarterial chemoperfusion (TACP) in locally recurrent pancreatic carcinoma and advanced tumor stages which did not respond to prior systemic chemotherapy. The tumor response, survival, and pain response were retrospectively analyzed. Materials and method: Forty outpatients (median age 62 years, range 36 - 79) were treated with a minimum of 3 (mean 6, range 3 - 12) applications per patient in four-week intervals. Twenty-eight patients were in advanced tumor stages, and 12 patients had locally recurrent tumors. Gemcitabine (1,000 mg/m{sup 2}) and mitomycin C (8.5 mg/m{sup 2}) were administered within 1 hour through a celiac trunk catheter. The tumor response (diameter, volume) was measured using MRI or CT and classified according to RECIST. The pain response was defined as a reduction of pain intensity of more than 50% on a visual analog scale, or a reduction of more than 50% in analgesics consumption, or a switch to a less potent analgesic agent. Results: The treatment was tolerated well by all patients. No clinically relevant problems or grade III or IV toxicity according to CTC (Common Toxicity Criteria) were observed. Tumor-related pain was relieved in 20/32 (62.5%) cases. Radiologically, 'complete response' was found in 3/40 (7.5%), 'partial response' in 9/40 (22.5%), 'stable disease' in 16/40 (40%), and 'progressive disease' in 12/40 (30%) of the patients. The median survival period since initial diagnosis and first TACP was 16.4 months and 8.1 months, respectively. Locally recurrent tumors showed better, but still not significant results regarding tumor response (41.7% vs. 25%) as well as survival (14.4 vs. 7 months) compared to advanced tumor stages. Responders (CR + PR) showed a significant survival advantage compared to patients with tumor progression (13.0 vs. 6.0 months; p = 0.013). (orig.)

    Twenty-one patients with stage III M 0 non-oat cell bronchogenic carcinoma confined to the thorax were randomized to receive either intrapleural BCG (10 7 cfu, Tice strain) or intrapleural saline 3 weeks prior to beginning combined irradiation and chemotherapy. Radiation to the primary tumor and regional nodes was given at a dose of 3,000 rad in ten sessions and was followed in 7-14 days by CAMP chemotherapy (cyclophosphamide, adriamycin, methotrexate, and procarbazine) for a planned duration of 6 months. Isoniazid, 300 mg/day, was given to all patients for 3 months starting 1 week after intrapleural therapy. There were no significant differences in pretreatment prognostic factors or in response to radiation therapy. The patients receiving intrapleural BCG in addition to radiation and chemotherapy had a median survival of 18 weeks, significantly shorter than that for the patients receiving intrapleural saline (54 weeks, P=0.017).

    The results of radiotherapy in 37 patients who were treated for carcinoma of the gallbladder from April 1975 to April 1992 are presented. To analyze the treatment results, patients were divided into four groups depending on treatment modality: intraoperative radiotherapy (IORT) with surgical resection in 9 (resection group), IORT with palliative surgery in 5 (palliative surgery group), hyperthermo-chemo-radiotherapy for inoperable cases in 11 (HCR group), external irradiation for inoperable cases in 12 (ExRT alone group). Most of the patients in the resection group received ExRT. The HCR group showed better local response than the groups treated with palliative surgery and ExRT alone. The mean length of survival in the resection, palliative surgery, HCR and ExRT alone groups was 315 days, 144 days, 246 days and 74 days, respectively. Although no statistically significant difference in survival was observed between the resection and HCR groups, the relapse-free interval of the resection group was significantly longer than that of the other groups. The application of IORT for surgically resectable tumors contributed to improved prognosis and better quality of life. Although IORT for patients with unresectable tumors had little effect on survival, it was considered to play a palliative role in improving the quality of life. The HCR group had a significantly longer survival time and relapse-free interval than the palliative surgery and ExRT alone groups. In conclusion, the application of HCR for inoperable carcinoma of the gallbladder contributed to the improvement of prognosis and quality of life. (author)

    Vandetanib, added to cisplatin and radiation therapy (RT) overcomes chemoradiation therapy (CRT) and epidermal growth factor receptor (EGFR) inhibitor resistance in head and neck squamous cell carcinoma (HNSCC) lines and models. Patients with previously untreated HNSCC received vandetanib daily for 14 days (starting dose 100 mg) and then vandetanib + RT (2.2 Gy/day, 5 days/week) for 6 weeks (regimen 1) or vandetanib + RT (2 Gy/day, 5 days/week) + cisplatin (30 mg/m(2) weekly) for 7 weeks (regimen 2). The primary objective was the maximum tolerated dose (MTD) of vandetanib with RT +/- cisplatin. Of 33 treated patients, 30 completed therapy (regimen 1, n = 12; regimen 2, n = 18). MTD in regimen 2 was 100 mg (3 dose limiting toxicities [DLTs] at 200 mg), whereas regimen 1 was stopped because of poor recruitment (1 DLT at 200 mg). Most common grade ≥3 adverse events (AEs) were dysphagia (30%), stomatitis (33%), and mucosal inflammation (27%). Five patients discontinued vandetanib because of AEs. Vandetanib with CRT was feasible. © 2015 Wiley Periodicals, Inc.

    Head and neck squamous cell carcinoma (HNSCC) has been increasingly recognized as an immune suppressive malignancy. The efficacy of immune checkpoint inhibitors (ICI's) in the context of recurrent/metastatic (R/M) setting anticipates the possible integration of immunotherapy into the therapeutic armamentarium of locally advanced disease. Durvalumab (DUR) is a humanized monoclonal IgG1, anti-PD-L1 antibody with promising data in R/M HNSCC. The aim of our study is to test the antitumor activity of a combined regimen incorporating an immune checkpoint inhibitor into a conventional bio-radiation strategy for the cure of unfavorable locally advanced HNSCC. In this open label, multi-center, single-arm, phase I/II study, enrolled patients will receive Radiotherapy (RT) (69.9 Gy/2.12 Gy in 33 fractions) with concurrent Cetuximab (CTX) (400 mg/m 2 1 week before RT start followed by 250 mg/m 2 weekly) and DUR (fixed dose of 1500 mg every 4 weeks starting from RT-CTX week 1) followed by adjuvant DUR (to a maximum of 6 months after completion of RT-CTX). Primary endpoint of the study is 2-year progression-free survival (PFS). A safety run-in is planned after the enrollment of first 12, 24 and 36 patients. Patients affected by high-risk (≥N2a or ≥T3, any N) larynx, hypopharynx and HPV negative oropharynx or HPV-positive oropharynx (≥T2, ≥N2b, ≥10 pack/years) will be eligible. Conventional intensification strategies failed to provide any benefit for the cure of locally advanced HNSCC. For the still prevalent HPV-negative population and the high risk-HPV positive disease, there is an unmet need for alternative treatment paradigms. Potentially, the inhibition of the PD-1/PD-L1 checkpoint may synergize with both CTX and RT through immunologic interplay, ultimately aiming to reverse the HNSCC-induced immune suppression. The DUCRO study will seek to demonstrate if such a strategy may be safe and active. NCT number: NCT03051906Eudract number: 2016-004668-20.

    Background: In this phase I/II study, the addition of lapatinib (LAP) was investigated in combination with the sequential use of both approaches TPF induction chemotherapy (ICT) followed by chemoradiation (CRT) in locally advanced larynx or hypopharynx squamous cell carcinoma. Patients and methods: Objectives were to assess maximum tolerated dose, dose-limiting toxicity (DLT) and to recommend a safe dose of LAP when administered with 4 cycles of TPF followed by CRT. Results: Seven male patients were included. Three patients were included in the first cohort, at dose level 1 (LAP 500 mg daily plus TPF). Renal toxicity was observed among these three patients (grade 3 [n = 1], grade 2 [n = 1] and grade 1 [n = 1]), with 1 DLT, leading to treatment interruption in this group. Nephrotoxicity was reversible after stopping LAP and hydration of the patients. In a second cohort of four patients administering docetaxel from the second cycle, 3 more DLTs were observed (grade 2 renal toxicity and grade 3 diarrhea, grade 3 anorexia and grade 3 stomatitis, and grade 4 neutropenia). Based on the occurrence of 4 DLTs at the first dose level of LAP, patient recruitment was closed. Conclusion: These data indicate that LAP cannot be combined safely with full dose TPF.

    An unusual case of advanced synchronous colon and gastric carcinoma is described. A 36 year old female was admitted to our Department with a stenosing right colon cancer diagnosed at endoscopy which was performed for lower crampy abdominal pain and gross blood in the stool. Multiple colon polyps, distal to the tumor, were also detected. On preoperative abdominal computed tomography, a stenosing right colon cancer, without evidence of abdominal diffusion, was confirmed. At laparotomy, in addition to colon cancer, an antral gastric cancer was incidentally found. En bloc hemi gastrectomy and subtotal colectomy were performed. Digestive continuity was restored by gastrojejunal and ileosigmoid anastomoses. At histology, a poorly differentiated gastric adenocarcinoma with signet ring-cell component (pT2, pN0; stage IB) and a moderately differentiated colon adenocarcinoma with a tubulovillous component (pT3, pN1; stage III, Stage Dukes C) were revealed. Both tumors showed a low expression of p53 and c-erb2 oncoproteins. No genetic defect was identified in the APC and MMR genes. The patient is alive, without recurrence, two years after the operation

    The objective of this study was to determine the incremental staging information provided by positron emission tomography/computed tomography (PET/CT) and its impact on management plans in patients with untreated stage III-IV head and neck squamous cell carcinoma (HNSCC). We prospectively studied, between September 2011 and February 2013, 84 consecutive patients [median age 63.5 years (39-84); 73 men] with histologically confirmed HNSCC. First, based on a conventional work-up (physical examination, CT imaging of the head, neck and chest), the multidisciplinary Head and Neck Tumour Board documented the TNM stage and a management plan for each patient, outlining the modalities to be used, including surgery, radiation therapy (RT), chemotherapy or a combination. After release of the PET/CT results, new TNM staging and management plans were agreed on by the multidisciplinary Tumour Board. Any changes in stage or intended management due to the PET/CT findings were then analysed. The impact on patient management was classified as: low (treatment modality, delivery and intent unchanged), moderate (change within the same treatment modality: type of surgery, radiation technique/dose) or high (change in treatment intent and/or treatment modality → curative to palliative, or surgery to chemoradiation or detection of unknown primary tumour or a synchronous second primary tumour). TNM stage was validated by histopathological analysis, additional imaging or follow-up. Accuracy of the conventional and PET/CT-based staging was compared using McNemar's test. Conventional and PET/CT stages were discordant in 32/84 (38 %) cases: the T stage in 2/32 (6.2 %), the N stage in 21/32 (65.7 %) and the M stage 9/32 (28.1 %). Patient management was altered in 22/84 (26 %) patients, with a moderate impact in 8 (9.5 %) patients and high impact in 14 (16.6 %) patients. PET/CT TNM classification was significantly more accurate (92.5 vs 73.7 %) than conventional staging with a p value < 0

    The aim of this study was to retrospectively observe and analyze the long-term treatment outcomes of a total of 140 esophageal cancer patients who were treated with californium-252 ( 252 Cf) neutron brachytherapy (NBT) in combination with external beam radiotherapy (EBRT) and concurrent chemotherapy (CCT). From January 2002 to November 2012, 140 patients with esophageal cancer underwent NBT in combination with EBRT and CCT. The distribution of the patient numbers over the various cancer stages of IIA, IIB, and III were 43, 7, and 90, respectively. The total radiation dose to the reference point via NBT was 8–25 Gy-eq in two to five fractions with one fraction per week. The total dose via EBRT was 50–60 Gy, which was delivered over a period of five to six weeks with normal fractionation. Fifty-four and 86 patients received tegafur suppositories (TS) and continuous infusion of fluorouracil (5-Fu) with cisplatin (CDDP), respectively. The median follow-up time was 42 months. The minimum follow-up was three months, and the maximum was 106 months. The overall median survival including death from all causes was 29.5 months. The five-year overall survival rate (OS) and local control (LC) were 33.4% and 55.9%, respectively. The chemotherapy regimen was a factor that was significantly associated with OS (p = 0.025) according to univariate analysis. The five-year OSs were 27.4% and 44.3% for the PF and TS chemotherapy regimens, respectively. Regarding acute toxicity, no incidences of fistula or massive bleeding were observed during this treatment period. The incidence of severe, late complications was related to the PF chemotherapy regimen (p = 0.080). The clinical data indicated that NBT in combination with EBRT and CRT produced favorable local control and long-term survival rates for patients with esophageal cancer and that the side effects were tolerable. A reasonable CRT regimen can decrease the rate of severe, late complications

    Twenty-seven patients with cervical metastases from squamous cell head and neck tumours were treated with hyperfractionated XRT (total dose 69.60-76.80 Gy, 1.2 Gy b.i.d. five times a week) combined with a total of two to six sessions of superficial external HT. Acute local toxicity was mild; as major acute side effects, only one ulceration was recorded. No severe late side effects were observed. Late toxicity was similar to that observed in our previous studies with the combination of heat and radiation. Nodal complete response was observed in 77% of patients, partial response was observed in 15% of patients and no change was observed in 8% of patients. Five-year actuarial nodal control was 64.5 ± 19% and 5-year actuarial survival was 24 ± 10%. The treatment of nodal metastases from head and neck tumours with the combination of HT and hyperfractionated XRT is feasible with an acceptable acute and late toxicity profile

    Purpose: Patients treated with chemoradiotherapy for locally advanced non–small-cell lung carcinoma (LA-NSCLC) were analyzed for local-regional failure (LRF) and overall survival (OS) with respect to radiotherapy dose intensity. Methods and Materials: This study combined data from seven Radiation Therapy Oncology Group (RTOG) trials in which chemoradiotherapy was used for LA-NSCLC: RTOG 88-08 (chemoradiation arm only), 90-15, 91-06, 92-04, 93-09 (nonoperative arm only), 94-10, and 98-01. The radiotherapeutic biologically effective dose (BED) received by each individual patient was calculated, as was the overall treatment time-adjusted BED (tBED) using standard formulae. Heterogeneity testing was done with chi-squared statistics, and weighted pooled hazard ratio estimates were used. Cox and Fine and Gray’s proportional hazard models were used for OS and LRF, respectively, to test the associations between BED and tBED adjusted for other covariates. Results: A total of 1,356 patients were analyzed for BED (1,348 for tBED). The 2-year and 5-year OS rates were 38% and 15%, respectively. The 2-year and 5-year LRF rates were 46% and 52%, respectively. The BED (and tBED) were highly significantly associated with both OS and LRF, with or without adjustment for other covariates on multivariate analysis (p < 0.0001). A 1-Gy BED increase in radiotherapy dose intensity was statistically significantly associated with approximately 4% relative improvement in survival; this is another way of expressing the finding that the pool-adjusted hazard ratio for survival as a function of BED was 0.96. Similarly, a 1-Gy tBED increase in radiotherapy dose intensity was statistically significantly associated with approximately 3% relative improvement in local-regional control; this is another way of expressing the finding that the pool-adjusted hazard ratio as a function of tBED was 0.97. Conclusions: Higher radiotherapy dose intensity is associated with improved local-regional control

    To assess late effects and quality of life in patients treated by three times daily (t.i.d.) radiotherapy with or without alternating chemotherapy for locally advanced squamous cell carcinoma of the head and neck. Between 1986 and 1991, 153 patients with locally advanced tumors have been included in a phase I/II study consisting of t.i.d. radiotherapy (4 h. between fractions) of 2 Gy/fraction to a total dose of 60 Gy, alternated or not with combination chemotherapy. The first group of patients received radiotherapy alone, the other group received combined modality. Ninety-two patients were eligible for late effect assessment: 61 in the combined modality group and 31 in the radiation therapy only group. The median follow-up was 45 months. All patients have been assessed according to the follow-up clinical records using the RTOG/EORTC classification. Twenty-nine patients, who were alive at the time of our study, received a questionnaire on their quality of life, and were invited for a clinical evaluation using the SOMA-LENT scale. Ninety percent of the patients treated by radiation therapy alone developed one or more late complications. Overall, 47% of the patients have developed severe complications (grade III and IV): 42% in the group treated by radiation therapy alone and 49% in the group treated with combined modality. In the group treated by radiation therapy alone, the most commonly damaged organs were the mucosa (83%), skin (51%) and salivary glands (42%). We observed one case of osteonecrosis and one case of radiation myelitis. In the combined modality group, 95% of patients developed one or more late sequelae, of which 79% had skin, 51% mucosa and 42% salivary gland late effects, respectively. We observed four cases of osteonecrosis. Quality of life and overall physical condition of the patients have been judged to be average by self-questionnaire. Assessment according to the SOMA-LENT scale showed serious late effects mainly at the level of the salivary

    The current standard therapy for locally advanced squamous cell carcinoma of the head and neck (LASCCHN) is platinum-based chemotherapy plus concurrent radiotherapy (CRT), but several systemic therapies have been evaluated. We performed a Bayesian network meta-analysis (NMA) with random effects to enable direct and indirect comparisons of all existing treatment modalities for LASCCHN simultaneously. A systematic review was conducted using MEDLINE, EMBASE, ASCO abstracts, ASTRO abstracts and the Cochrane Central of Registered Trials using Cochrane methodology to identify randomized controlled trials (RCTs) up to June 2016. Only abstracts that involved the same definitive radiotherapy in the arms for the RCT were included. Sixty-five RCTs involving 13,574 patients and 16 different treatment strategies were identified. Chemotherapy plus concurrent radiation (CRT) was superior to RT with a HR of 0.74 (95%CR 0.69-0.79) for OS in the NMA. Only 3 trials compared RT alone to concurrent therapy with an EGFR antibody (ERT), demonstrating a superior OS (HR 0.75, 95% CR 0.60-0.94), but this difference was not statistically significant when interpreted in a NMA (HR 0.84, 95%CR 0.65-1.08). ERT was not superior to CRT (HR 1.19, 95%CR 0.93-1.54), and the addition of neo-adjuvant taxane-based chemotherapy to CRT was not beneficial (HR 0.86, 95% CR 0.70-1.07). The addition of either adjuvant or neoadjuvant chemotherapy to the CRT backbone does not confer an OS benefit in the treatment of LASCCHN. Similarly, ERT does not confer an OS benefit for patients who are eligible for CRT. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available To evaluate the rationality and limitations of the seventh edition of the American Joint Committee on Cancer (the 7th AJCC edition T-staging system for locally advanced nasopharyngeal carcinoma (NPC. The prognosis of 358 patients with stage T3/T4 NPC treated with intensity-modulated radiotherapy (IMRT was analyzed with the Kaplan–Meier method or the log-rank test. The 7th AJCC staging system of NPC has some limitations in that the T category is neither the significant factor in OS/LRFS nor the independent prognostic factor in OS/LRFS/DMFS/DFS (P>0.05. After adjustment by anatomic structures, univariate analysis has shown that the adjusted-T category has statistical significance between T3 and T4 for OS (86.4% and 71.3%, P=0.002, LRFS (97% and 90.9%, P=0.048, DMFS (90.9% and 77.2%, P=0.001, and DFS (86.2% and 67.5%, P=0.000, and multivariate analysis has shown that the adjusted-T category is an independent prognostic factor for OS/DMFS/DFS (with the exception of LRFS. Then, GTV-P was taken into consideration. Multivariate analysis showed that these nT categories serve as suitable independent prognostic factors for OS/DMFS/DFS (P<0.001 and LRFS (HR = 3.131; 95% CI, 1.090–8.990; P=0.043. The 7th AJCC staging system has limitations and should be improved by including the modifications suggested, such as anatomic structures and tumor volume adjustment.

    Locally advanced invasive cervical cancer [International Federation of Gynecology and Obstetrics (FIGO) IIB/III] is treated by chemoradiation. The response to treatment is variable within a given FIGO stage. Therefore, the aim of the present study was to evaluate the gene promoter methylation profile and corresponding transcript expression of a panel of six genes to identify genes which could predict the response of patients treated by chemoradiation. In total, 100 patients with invasive cervical cancer in FIGO stage IIB/III who underwent chemoradiation treatment were evaluated. Ten patients developed systemic metastases during therapy and were excluded. On the basis of patient follow-up, 69 patients were chemoradiation-sensitive, whereas 21 were chemoradiation-resistant. Gene promoter methylation and gene expression was determined by TaqMan assay and quantitative real-time PCR, respectively, in tissue samples. The methylation frequency of ESR1, BRCA1, RASSF1A, MLH1, MYOD1 and hTERT genes ranged from 40 to 70%. Univariate and hierarchical cluster analysis revealed that gene promoter methylation of MYOD1, ESR1 and hTERT could predict for chemoradiation response. A pattern of unmethylated MYOD1, unmethylated ESR1 and methylated hTERT promoter as well as lower ESR1 transcript levels predicted for chemoradiation resistance. Methylation profiling of a panel of three genes that includes MYOD1, ESR1 and hTERT may be useful to predict the response of invasive cervical carcinoma patients treated with standard chemoradiation therapy.

    Objective: To evaluate the efficacy of interventional therapy for advanced pancreatic carcinoma. Methods: 33 cases of advanced pancreatic carcinoma accepted interventional therapy from April 2005 were retrospectively analyzed. All patients were unoperable and accepted one or more times of celiac and superior mesenteric arterial chemotheraputics perfusion with dosage of 2:1. The embolization was further introduced with the addition of liver invasion. The repetition interval was kept at 6 weeks with no severe complications. Results: The one with follow-up CT imagings showed obvious decrease of the lesion size, together with release or disappearance of the sensation of abdominal pain and abdominal distention. The life span prolonged with average survival of 13 months, including the longest of 22 months and the life quality improved. Conclusions: The interventional therapy could be the first method of choice in the management of advanced pancreatic carcinoma. (authors)

    Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an autosomal dominant tumor susceptibility syndrome, and the disease-related gene has been identified as fumarate hydratase (fumarase, FH). HLRCC-associated kidney cancer is an aggressive tumor characterized by early metastasis to regional lymph nodes and distant organs. Since early diagnosis and provision of definitive therapy is thought to be the best way to reduce the tumor burden, it is widely accepted that germline testing and active surveillance for an at-risk individual from a family with HLRCC is very important. However, it still remains controversial how we should treat HLRCC-associated kidney cancer. We successfully treated the patient with locally advanced HLRCC-associated kidney cancer, who has received active surveillance because of at-risk individual, by radical nephrectomy and extended retroperitoneal lymph node dissection, and examined surgically resected samples from a molecular point of view. We recommended that 13 at-risk individuals from a family with HLRCC should receive active surveillance for early detection of renal cancer. A 48-year-old woman with a left renal tumor and involvement of multiple regional lymph nodes with high accumulation of fluorine-18-deoxyglucose on positron emission tomography was treated with axitinib as a neoadjuvant therapy. Preoperative axitinib induced the shrinkage of the tumor with decreased fluorine-18-deoxyglucose accumulation. Resected samples showed two thirds tumor tissue necrosis as well as high expression of serine/threonine kinase Akt and low expression of nuclear factor E2-related factor 2 (Nrf2) which activates anti-oxidant response and protects against oxidative stress in viable cancer cells. Targeted next-generation sequencing revealed that FH mutation and loss of the second allele were completely identical between blood and tumor samples, suggesting that FH mutation plays a direct role in FH-deficient RCC. She has remained well after radical

    Purpose: Induction chemotherapy (ICT) has been used to select patients for organ preservation and determine subsequent treatments in patients with locally advanced squamous cell carcinoma of the head and neck (LASCCHN). Still, the clinical outcomes of LASCCHN patients who showed response to ICT are heterogeneous. We evaluated the efficacy of interim 18-fluoro-2-deoxy-glucose positron emission tomography (FDG-PET) after ICT in this specific subgroup of LASCCHN patients who achieved partial response (PR) after ICT to predict clinical outcomes after concurrent chemoradiotherapy (CCRT). Methods and Materials: Twenty-one patients with LASCCHN who showed PR to ICT by Response Evaluation Criteria In Solid Tumors before definitive CCRT were chosen in this retrospective analysis. FDG-PET was performed before and 2-4 weeks after ICT to assess the extent of disease at baseline and the metabolic response to ICT, respectively. We examined the correlation of the metabolic response by the percentage decrease of maximum standardized uptake value (SUVmax) on the primary tumor or lymph node after ICT or a specific threshold of SUVmax on interim FDG-PET with clinical outcomes including complete response (CR) rate to CCRT, progression-free survival (PFS), and overall survival (OS). Results: A SUVmax of 4.8 on interim FDG-PET could predict clinical CR after CCRT (100% vs. 20%, p = 0.001), PFS (median, not reached vs. 8.5 mo, p < 0.001), and OS (median, not reached vs. 12.0 months, p = 0.001) with a median follow-up of 20.3 months in surviving patients. A 65% decrease in SUVmax after ICT from baseline also could predict clinical CR after CCRT (100% vs. 33.3%, p = 0.003), PFS (median, not reached vs. 8.9 months, p < 0.001) and OS (median, not reached vs. 24.4 months, p = 0.001) of the patients. Conclusion: These data suggest that interim FDG-PET after ICT might be a useful determinant to predict clinical outcomes in patients with LASCCHN receiving sequential ICT followed by CCRT.

    To evaluate the prognostic utility of nodal metabolic parameters derived from FDG PET/CT performed before radiotherapy (prePET) and during the third week of radiotherapy (iPET) in patients with mucosal primary head and neck squamous cell carcinoma (MPHNSCC). This analysis included 75 patients with newly diagnosed locally advanced node-positive MPHNSCC treated with radical radiotherapy and concurrent systemic therapy who underwent prePET and iPET: N1 11 patients, N2a 38, N2b 12, N2c 9, N3 5. The median follow-up was 28 months (9 - 70 months). The maximum and mean standardized uptake values (SUVmax and SUVmean), metabolic tumour volume (MTV) and total lesional glycolysis (TLG) of the index lymph node (node with the highest TLG) and the combined total lymph nodes, and their percentage reductions on iPET were determined, and the results were correlated with 3-year Kaplan-Meier locoregional, regional and distant metastatic failure-free survival (FFS), disease-free survival (DFS) and overall survival (OS). Optimal cut-off values were derived from receiver operating characteristic curves. Cox regression univariate and multivariate analyses with clinical covariates were performed. Based on assessment of residual nodal metabolic burden during treatment, the iPET index node SUVmean (optimal cut-off value 2.95 g/ml) and the total node SUVmean (optimal cut-off value 3.25) were the best independent predictors of outcome in the multivariate analysis: index node SUVmean for DFS and OS p = 0.033 and 0.003, respectively, and the total node SUVmean for locoregional FFS, DFS and OS p = 0.028, 0.025 and 0.014, respectively. Based on the assessment of response rates during treatment, a reduction of more than 50 % in the total node TLG was the best biomarker for locoregional and regional FFS, DFS and OS in the multivariate analysis (p = 0.001, 0.016, 0.001 and 0.004, respectively), and reduction in the total node MTV for locoregional FFS, DFS and OS (p = 0.026, 0.003 and 0

    In a 10-year interval 179 patients with prostatic carcinoma were treated by cobalt-60 teletherapy (7600 R). A selected group of 47 patients with localized disease and irradiated with curative intent had serial prostatic biopsies and were analized after a minimum follow-up of 1 year. Biopsies of half of the patients rendered definitively negative, on an average 14 months after radiotherapy. 8 patients with initial negative biopsy changed to positive secondarily. In one third of the patients histological conversion was missed, considered as radiation persister. Persistent carcinoma were of predominant low grade. 5 patients developed distant metastases 30 months after irradiation on an average. These patients had persistent positive tissue studies. Over all cumulative 5-years survival was 89%. In patients with prostatic carcinoma and local high voltage radiotherapy with curative intent (stage A through C) serial prostatic biopsies to document therapy effect seen mandatory.

    The incidence of hepatocellular carcinoma (HCC) is increasing, and it is currently the second leading cause of cancer-related death worldwide. Potentially curative treatment options for HCC include resection, transplantation, and percutaneous ablation, whereas palliative treatments include trans-arterial chemoembolization (TACE), radioembolization, and systemic treatments. Due to the diversity of available treatment options and patients’ presentations, a multidisciplinary team should decide clinical management of HCC, according to tumor characteristics and stage of liver disease. Potentially curative treatments are suitable for very-early- and early-stage HCC. However, the vast majority of HCC patients are diagnosed in later stages, where the tumor characteristics or progress of liver disease prevent curative interventions. For patients with intermediate-stage HCC, TACE and radioembolization improve survival and are being evaluated in addition to potentially curative therapies or with systemic targeted therapy. There is currently no effective systemic chemotherapy, immunologic, or hormonal therapy for HCC, and sorafenib is the only approved molecular-targeted treatment for advanced HCC. Other targeted agents are under investigation; trials comparing new agents in combination with sorafenib are ongoing. Combinations of systemic targeted therapies with local treatments are being evaluated for further improvements in HCC patient outcomes. This article provides an updated and comprehensive overview of the current standards and trends in the treatment of HCC. PMID:25866604

    Full Text Available Hepatocellular carcinoma (HCC, one of the most common malignancies with high prevalence and mortality rate, usually results in poor prognosis and limited survival. A comprehensive analysis on the number and location of tumors, Child-Pugh grade, and Barcelona Clinic Liver Cancer stage will help the development of suitable treatment programs and improve prediction of prognosis. A majority of patients are complicated by cirrhosis, enlarged tumor, multiple lesions, vascular invasion, and even cancer embolus in the portal vein. With the growth of knowledge about the radiation tolerance of normal tissue and the advances in radiotherapy techniques, radiotherapy has become an important tool for step-down therapy and adjuvant therapy for liver cancer. Proton beam therapy (PBT is emerging as a novel radiotherapy for the management of HCC, which, benefiting from the effect of Bragg Peak from PBT, effectively decreases the toxicity of traditional radiotherapies to the liver and does little harm to the uninvolved liver tissue or the surrounding structures while intensifying the destruction in targeted malignant lesions. Furthermore, several previous studies on the treatment of HCC with PBT revealed excellent local control. The distinctive biophysical attributes of PBT in the treatment of HCC, as well as the available literature regarding clinical outcomes and toxicity of using PBT for HCC, are reviewed. Current evidence provides limited indications for PBT, which suggests that further study on the relationship between liver function and PBT is required to gain further insight into its indication and standardization.

    2016-01-01

    Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality and has an increasing incidence worldwide. HCC can be induced by multiple etiologies, is influenced by many risk factors, and has a complex pathogenesis. Furthermore, HCCs exhibit substantial heterogeneity, which compounds the difficulties in developing effective therapies against this highly lethal cancer. With advances in cancer biology and molecular and genetic profiling, a number of different mechanisms involved in the development and progression of HCC have been identified. Despite the advances in this area, the molecular pathogenesis of hepatocellular carcinoma is still not completely understood. This review aims to elaborate our current understanding of the most relevant genetic alterations and molecular pathways involved in the development and progression of HCC, and anticipate the potential impact of future advances on therapeutic drug development.

    Full Text Available Abstract Background Our objective was to test a brief, symptom index for advanced renal cell carcinoma, a disease affecting over 38,000 Americans each year and often diagnosed in late stages. Methods We conducted secondary data analyses on patient-reported outcomes of 209 metastatic renal cell carcinoma patients participating in a Phase III clinical trial. Patient-reported outcomes, obtained from the FACT-Biological Response Modifier (FACT-BRM scale, were available at baseline, 2, and 8 weeks. We analyzed data from eight FACT-BRM items previously identified by clinical experts to represent the most important symptoms of advanced renal cell carcinoma. Items comprising this index assess nausea, pain, appetite, perceived sickness, fatigue and weakness, with higher scores indicating fewer symptoms. We determined reliability and validity of the index and estimated a minimally important difference. Results The index had excellent internal reliability at all three time points (alphas ≥ 0.83. Baseline scores were able to discriminate patients across Karnofsky performance status, number of metastatic sites, and risk group categories (ps Conclusion The 8-item index of patient-reported symptoms of renal cell carcinoma appears to be a psychometrically sound measure. It is a brief, reliable, and valid measure that can easily be adapted for use in clinical trials and observational studies.

    Tumor angiogenesis has been found to have prognostic significance in many tumor types for predicting an increased risk of metastasis. We assessed tumor vascularity in 43 cases of advanced stage (International Federation of Gynecologists and Obstetricians stages III and IV) ovarian cancer by using the highly specific endothelial cell marker CD34. Microvessel counts and stage were associated with disease-free survival and with overall survival by Kaplan-Meier analysis. The plots show that higher stage, higher average vessel count at 200x (200x avg) and 400x (400x avg) magnification and highest vessel count at 400x (400x high) magnification confer a worse prognosis for disease-free survival. Average vessel count of less than 16 (400x avg, P2 = 0.01) and less than 45 (200x avg, P2 = 0.026) suggested a better survival. Similarly, a high vessel count of less than 20 (400x high, P2 = 0.019) conferred a better survival as well. The plots suggest that higher stage, higher average vessel count at 200x and 400x, and highest vessel count at 200x and 400x show a trend to worse overall survival as well. With the Cox proportional hazards model, stage was the best predictor of overall survival, however, the average microvessel count at 400x was found to be the best predictor of disease-free survival. These results suggest that analysis of neovascularization in advanced stage ovarian cancer may be a useful prognostic factor.

    The purpose of this study is to present the treatment results and to identify possible prognostic indicators in patients with locally advanced hypopharyngeal carcinoma. Materials and Methods: Between October 1985 to December 2000, 90 patients who had locally advanced stage IV hypopharyngeal carcinoma were studied retrospectively. Twelve patients were treated with radiotherapy alone, 65 patients were treated with a combination of chemotherapy and radiotherapy, and 13 patients were treated with surgery and postoperative radiotherapy with or without neoadjuvant chemotherapy. Total radiation dose ranged from 59.0 to 88.2 Gy (median 70 Gy) for radiotherapy alone. Most patients had ciplatin and 5-fluorouracil, and others had cisplatin and peplomycin or vincristin. Median follow-up period was 15 months. Kaplan-Meier method was used for survival rate and Cox proportional hazard model for multivariate analysis of prognostic factors. Results: Overall 3- and 5-year survival rates were 27% and 17%, respectively. The 2-year locoregional control rates were 33% for radiotherapy alone, 32% for combined chemotherapy and radiotherapy, and 81% for combined surgery and radiotherapy (p=0.006). The prognostic factors affecting overall survival were T stage, concurrent chemo radiation and treatment response. Overall 3- and 5-year laryngeal preservation rates in combined chemotherapy and radiotherapy were 26% and 22%, respectively. Of these, the 5-year laryngeal preservation rates were 52% for concurrent chemo radiation group (n=11), and 16% for neoadjuvant chemotherapy and radiotherapy (n=54, p=0.012). Conclusion: Surgery and postoperative radiotherapy showed better results than radiotherapy alone or with chemotherapy. Radiotherapy combined with concurrent chemotherapy is an effective modality to achieve organ preservation in locally advanced hypopharyngeal cancer. Further prospective randomized studies will be required

    The results of two studies looking at the place of neo-adjuvant chemotherapy in the treatment of locally advanced cervical cancer being treated with radiotherapy are presented. Between August 1990 and January 1992, 184 patients with squamous cell carcinoma of the cervix, FIGO stage II B IVA were randomised (study 1) to receive either two cycles of bleomycin, ifosfamide-mesna and cisplatin (BIP) chemotherapy (CT) followed by radiotherapy (RT). Three patients died of CT toxicity - two in study 1 and one in study 2. Cystitis, proctitis and local skin reaction after RT occurred equally in the two groups in both the studies. The neo-adjuvant chemotherapy prior to radiotherapy demonstrated a high response rate, but this did not translate into improved overall survival compared to those patients receiving radiotherapy alone

    Full Text Available In this article we consider the application of local data as a means of advancing quantitative literacy. We illustrate the use of three different sources of local data: institutional data, Census data, and the National College Health Assessment survey. Our learning modules are applied in courses in sociology and communication, but the strategy of using local data can be integrated beyond these disciplinary boundaries. We demonstrate how these data can be used to stimulate student interests in class discussion, advance analytic skills, as well as develop capacities in written and verbal communication. We conclude by considering concerns that may influence the types of local data used and the challenges of integrating these data in a course in which quantitative analysis is not typically part of the curriculum.

    In this study, it was investigated whether dose response relation existed or not in local radiotherapy for primary hepatocellular carcinoma. From January 1992 to March 2000, 158 patients were included in present study. Exclusion criteria included the presence of extrahepatic metastasis, liver cirrhosis of Child's class C, tumors occupying more than two thirds of the entire liver, and performance status on the ECOG scale of more than 3. Radiotherapy was given to the field including tumor with generous margin using 6, 10-MV X-ray. Mean tumor dose was 48.2±7.9 Gy in daily 1.8 Gy fractions. Tumor response was based on diagnostic radiologic examinations such as CT scan, MR imaging, hepatic artery angiography at 4-8 weeks following completion of treatment. Statistical analysis was done to investigate the existence of dose response relationship of local radiotherapy when it was applied to the treatment of primary hepatocellular carcinoma. An objective response was observed in 106 of 158 patients, giving a response rate of 67. 1%. Statistical analysis revealed that total dose was the most significant factor in relation to tumor response when local radiotherapy was applied to the treatment of primary hepatocellular carcinoma. Only 29.2% showed objective response in patients treated with dose less than 40 Gy, while 68.6% and 77.1 % showed major response in patients with 40-50 Gy and more than 50 Gy, respectively. Child-Pugh classification was significant factor in the development of ascites, overt radiation induced liver disease and gastroenteritis. Radiation dose was an important factor for development of radiation induced gastroduodenal ulcer. Present study showed the existence of dose response relationship in local radiotherapy for primary hepatocellular carcinoma. Only radiotherapy dose was a significant factor to predict the objective response. Further study is required to predict the maximal tolerance dose in consideration of liver function and non-irradiated liver

    Objective: to assess the treatment of breast cancer T2 and T3(T > = 4 cm), through neoadjuvant chemotherapy, quadrantectomy and high-dose-rate (HDR) brachytherapy as a boost, complementary radiotherapy and adjuvant chemotherapy, considering its method problems, its esthetics results, the aspect of local control, overall survival, and disease-free survival. Patients and method: this clinical prospective descriptive study was based on the evaluation of 26 patients ranging from 30 to 70 years old, with infiltrating ductal carcinoma, clinical stage IIB and IIIA, responsive to the neoadjuvant chemotherapy. Early and late radiotherapy complications were evaluated according to the criteria established by the RTOG/EORTC (Radiotherapy and Oncology Group /European Organization for Research and Treatment of Cancer) groups. Esthetics evaluation was done in accordance with the criteria set by a plastic surgeon. Local control was evaluated by clinical method, mammography and ultrasonography. Overall survival (OS) and the disease-free survival (DFS) were assessed according to Kaplan-Meier methodology. All the patients were treated at the Dr. Arnaldo Vieira de Carvalho Cancer Institute, from June/1995 to November/2001, and evaluated in March, 2002, with median follow-up of 28.7 months. Results: early complications were observed in 8 patients (30.6%). Two patients were classified as G3 and G4 (RTOG/EORTC). Six patients had late complications and three of them (11.5%) were classified as G3 and G4. One patient (3.8%) had local recurrence, 64 months after having local treatment. Esthetics results were considered good or regular in 16 patients (60.5%) out of 24 patients who were examined. Overall survival and disease-free survival in 24, 36 and 60 months were 100%, 92.3% and 83.1% respectively. Conclusion: early and late radiotherapy complications were considerate high when compared to literature, but esthetic results were considered acceptable. RL, OS and DFS were comparable to other

    Full Text Available BACKGROUD: There is substantial evidence that infection with Helicobacter pylori plays a role in the development of gastric cancer and that it is rarely found in gastric biopsy of atrophic gastritis and gastric cancer. On advanced gastric tumors, the bacteria can be lost from the stomach. AIMS: To analyze the hypothesis that the prevalence of H.pylori in operated advanced gastric carcinomas and adjacent non-tumor tissues is high, comparing intestinal and diffuse tumors according to Lauren's classification METHODS: A prospective controlled study enrolled 56 patients from "Hospital Universitário", Federal University of Rio Grande do Norte, Natal, RN, Brazil, with advanced gastric cancer, treated from February 2000 to March 2003. Immediately after partial gastrectomy, the resected stomach was opened and several mucosal biopsy samples were taken from the gastric tumor and from the adjacent mucosa within 4 cm distance from the tumor margin. Tissue sections were stained with hematoxylin and eosin. Lauren's classification for gastric cancer was used, to analyse the prevalence of H. pylori in intestinal or diffuse carcinomas assessed by the urease rapid test, IgG by ELISA and Giemsa staining. H. pylori infected patients were treated with omeprazole, clarithromycin and amoxicillin for 7 days. Follow-up endoscopy and serology were performed 6 months after treatment to determine successful eradication of H. pylori in non-tumor tissue. Thereafter, follow-up endoscopies were scheduled annually. Chi-square and MacNemar tests with 0.05 significance were used. RESULTS: Thirty-four tumors (60.7% were intestinal-type and 22 (39.3% diffuse type carcinomas. In adjacent non-tumor gastric mucosa, chronic gastritis were found in 53 cases (94.6% and atrophic mucosa in 36 patients (64.3%. All the patients with atrophic mucosa were H. pylori positive. When examined by Giemsa and urease test, H. pylori positive rate in tumor tissue of intestinal type carcinomas was

    The purpose of this study was to analyse the usefulness of high resolution CT (HRCT) for the diagnosis and localization of roentgenographically occult lung cancer. HRCT was performed prospectively on chest X-ray negative patients with bloody sputum or suspicious or positive cells on sputum cytology between 1998 and 2000. After the HRCT scan, white light bronchoscopy and autofluorescence bronchoscopy were performed. HRCT depicted 19 hilar bronchial lesions in 13 cases out of 19 patients, of which 9 lesions were confirmed by white light broncoscope. Of 8 hilar squamous cell carcinomas diagnosed in this study, 7 lesions (87.5%) were depicted by HRCT. One CT-negative case (12.5%) was an in situ carcinoma in left B 1+2 . Four out of 20 lesions which showed bronchoscopic abnormality, could not be depicted by HRCT. HRCT could prospectively detect 80% of the bronchoscopic abnormalities and 87.5% of the hilar squamous cell carcinomas of the tracheobronchial lesions of the lung. Therefore, HRCT can be an effective supplemental means for screening for hilar squamous cell carcinoma. (author)

    Full Text Available CONTEXT: Synchronous associations of esophageal and gastric cancers are not a common finding, especially with differing histological types and both tumors in advanced forms. A case with such an association is presented, in which an unusual therapy was proposed: palliative gastrectomy and esophageal intubation. CASE REPORT: A 75-year-old white man was referred to our service complaining of malaise and weight loss for one year and dysphagia and vomiting for 2 months. The patient had sought out medical consultation as a result of the latter two complaints.

    Clinical results of intraoperative radiotherapy (IOR) in carcinoma of the stomach and prostate, and malignant soft tissue tumors are reported. The 5-year survival rate was found to be increased by IOR in stages II-IV gastric cancer. From the analysis of the clinical results of prostatic cancer, a single dose of 3,500 rad was considered to be a potential curative dose for the tumor less than 3 cm in diameter. The local recurrence rate of patients with malignant soft tissue tumors who received a single dose ranging from 3,000 to 4,500 rad was 5.9 and the 5-year survival rate was 64.6 %.

    From 1991 to 1995; 31 patients (mid-age: 70 years) underwent prostatic brachytherapy for localized prostate cancers using Iridium 192 transperineal percutaneous interstitial implantation guided by transrectal ultrasonography. Initial staging included among other evaluations a bilateral staging, iliac and obturator lymph nodes dissection. Classification according to stage was : T1b=16%, T1c=36%, T2a=19%, T2b=13%, T2c=13%, T3a=3%. All patients were N (-). Gleason score was 5 for 55%. 77% of the initial PSA was < 25μg/l. Follow-up included one clinical control and psa determination at 1-3-6-12 and 18 months, bone scanning at 12 months and prostate biopsy guided by transrectal ultrasonography at 18, 24, 30 months. Up to now, mean follow-up is 32 months. At one month, psa was normal (< 2,5μg/l) in 21% of the patients, at 12 months 60% and 67% two years after brachytherapy. Biopsies at 18 months were negative for 60% of the patients and 63% at 24 months. 3 patients were metastased after 3 years. 4 patients had severe complications with colostomy and/or urinary derivation. This technic seems to be interesting for localized prostate cancers T1 and T2 with initial psa < 25μg/l. Two third of the patients had normal psa and negative biopsies after 2 years. The rate of ano-rectal and urinary morbidity is high but is explained by the technic used at the beginning of this study

    Patients with advanced hypopharyngeal carcinoma still have a poor outcome in spite of radical surgery with chemoradiotherapy. We started superselective intra-arterial infusion chemotherapy with concomitant radiotherapy (IA chemoradiation) for advanced hypopharyngeal carcinoma in 2003. The complete response (CR) rate for local and neck lesions was 94.1% and 60%, respectively. After neck dissection the total CR rate was 82.4%. There was no significant difference in survival rates between groups with IA chemoradiation (n=22) and with surgery with preoperative chemoradiotherapy (n=57). However, Kaplan-Meier analysis showed that the cause-specific survival rate in N3 patients and larynx preservation rate was significantly higher in patients treated with IA chemoradiation than in those with surgery with preoperative chemoradiotherapy (p<0.05 and p<0.001). Subjective symptoms are not so severe in patients without the disease after IA chemoradiation. IA chemoradiation is effective for patients with advanced hypopharyngeal carcinoma to maintain quality of life such as voice and swallowing. (author)

  12. Advanced design of local ventilation systems

    Local ventilation is widely used in industry for controlling airborne contaminants. However, the present design practices of local ventilation systems are mainly based on empirical equations and do not take quantitatively into account the various factors affecting the performance of these systems. The aim of this study was to determine the applicability and limitations of more advanced fluid mechanical methods to the design and development of local ventilation systems. The most important factors affecting the performance of local ventilation systems were determined and their effect was studied in a systematic manner. The numerical calculations were made with the FLUENT computer code and they were verified by laboratory experiments, previous measurements or analytical solutions. The results proved that the numerical calculations can provide a realistic simulation of exhaust openings, effects of ambient air flows and wake regions. The experiences with the low-velocity local supply air showed that these systems can also be modelled fairly well. The results were used to improve the efficiency and thermal comfort of a local ventilation unit and to increase the effective control range of exhaust hoods. In the simulation of the interaction of a hot buoyant source and local exhaust, the predicted capture efficiencies were clearly higher than those observed experimentally. The deviations between measurements and non-isothermal flow calculations may have partly been caused by the inability to achieve grid independent solutions. CFD simulations is an advanced and flexible tool for designing and developing local ventilation. The simulations can provide insight into the time-averaged flow field which may assist us in understanding the observed phenomena and to explain experimental results. However, for successful calculations the applicability and limitations of the models must be known. (orig.) 78 refs.

    Full Text Available More and more clinical trials have proved the efficacy of targeted drugs in the treatment of hepatocellular carcinoma (HCC. With the development of science and technology, more and more targeted drugs have appeared. In recent years, targeted drugs such as regorafenib and ramucirumab have shown great potential in related clinical trials. In addition, there are ongoing clinical trials for second-line candidate drugs, such as c-Met inhibitors tivantinib and cabozantinib and a VEGFR-2 inhibitor ramucirumab. This article summarizes the advances in targeted drug therapy for HCC and related trial data, which provides a reference for further clinical trials and treatment.

    Radiation theraoy should be fully used in the management of advanced breast cancer. Locally advanced primary or recurrent carcinoma, with limited extent, should be treated aggressively, aimed at permanent control. Palliative treatment of incurable or metastatic lesions relieves symptoms and improves patient's quality of survival. Some metastatic lesions involving vital structures may create emergencies. Prompt institution of radiation therapy may reverse the serious complication and save the patient's life

    Two cases of biopsy-proven conjunctival squamous cell carcinoma (SCC) that developed local and regional spread are described. The cases involved a 65-year-old woman and a 79-year-old man who were initially treated at outside institutions for SCC of the conjunctiva. The patients did not have a history of immune compromise. The female patient presented with direct extension into the lacrimal gland but deferred recommended exenteration. Despite eventual exenteration, she developed metastasis to a neck node 6 months later, which was treated with radiotherapy. The male patient presented with local recurrence and a parotid node metastasis treated with exenteration, parotidectomy, selective neck dissection, and postoperative radiotherapy. Review of the outside pathology of both cases revealed positive tumor margins at the time of original resection. Local control of conjunctival SCC is of critical importance to reduce the risk of orbital extension and regional spread.

    Local failure rates following treatment for squamous cell carcinoma of the oral cavity have been reported to be in the range of 25%-48%. This study investigated the pattern of failure for squamous cell carcinoma (SCC) of the oral cavity and evaluated salvage surgery for local recurrent disease. The tumor files of 549 patients undergoing treatment for SCC of the oral cavity between 1980 and 2000 at Chiba Cancer Center Hospital were reviewed. Of 549 patients, 289 were initially treated with radiation therapy for their primary tumor, and 260 with surgery, either with or without radiation therapy. One hundred and sixty-one patients developed failures, yielding a failure rate of 29.3%. The site of recurrent tumor was local in 72 (13.1%) patients, regional in 89 (16.2%) patients, and distant in 5 (0.9%) patients. Local failure developed in 49 (17.0%) patients with radiation therapy and in 23 (8.8%) patients with surgery. Out of these 72 patients with local failure, 41 (56.9%) patients had salvage surgery for their disease. Twenty-five (73.5%) of the 34 patients initially treated with radiation therapy were salvaged with surgery, and 4 (57.1%) of the 7 patients initially treated with surgery were cured with further surgery. For the treatment of patients with local failure, the disease should be diagnosed more carefully than untreated disease. The disease that has recurred after radiation therapy may be more likely to be salvaged by surgery, however, the disease that has developed after surgery may have a limited indication for re-surgery.

    Objective: To evaluate the transarterial chemoembotherapy in the treatment of advanced or late staged digestive tract carcinoma. Methods: One hundred fifty-one patients with advanced or late staged digestive tract carcinoma (including 20 cases of esophageal carcinoma, 29 cases of cardia carcinoma, 71 cases of gastric carcinoma and 31 cases of large intestinal carcinoma) underwent super selective transarterial chemoembotherapy. Results: Interventions were successful. Symptoms were apparently improved in all cases. Decreased diameter of tumor was seen in all cases. Half-year survival rate was 95% (144/151); one year survival was 86% (130/150); two year survival rate was 66% (99/151); and three year survival rate was 29% (44/151). Conclusion: The transarterial chemoembotherapy is an effective treatment of advanced or late staged digestive tract carcinoma. In patients with metastases, the intervention is especially valuable for both primary and metastatic lesions

    A total of 58 cases with inoperable advanced gastric carcinomas were treated by radiotherapy combined with tegafur, and the result was analyzed mainly from the aspects of life expectancies and some prognostic factors. Median survival time of all cases was 8.9 months. Actuarial survival rates at one, two, three, four and five years were 45%, 22%, 14%, 14% and 11% respectively. Cancer type, histologic type, tumor size and radiation effect on the primary lesion were chosen as the prognostic factors, and examined using median survival time as a parameter. Borrmann IV type cancer showed an unequivocally poor prognosis, whereas no significant prognostic differences were seen among other types. Poorly differentiated adenocarcinoma gave a poor prognosis. Radiation effect on the primary lesion seemed to have a positive correlation with prognosis, while life expectancies became shorter with the increase of tumor size. It seems, from the present study, that this combination therapy contributes a great deal to life prolongation of patients with inoperable advanced gastric carcinomas.

    Full Text Available Purpose: To assess the efficacy of radiation in the treatment of juvenile nasopharyngeal angiofibroma (JNA. Materials and Methods: Data were retrieved for JNA treated with radiotherapy from 1987-2012. The demographics, treatment and outcome data were recorded in predesigned proforma. Results: Data of 32 patients were retrieved. Median age was 17 years (range: 12-33 years. All patients received radiation because of refractory, residual or unresectable locally advanced disease. All patients were planned with a three-dimensional conformal technique (3DCRT. The median radiation dose was 30 Gray (range: 30-45 Gray. Median follow-up was 129 months (range: 1-276 months. At the last follow-up, 13 patients were found to have a radiological complete response. Two patients progressed 38 and 43 months after completion of treatment and opted for alternative treatment. One patient developed squamous cell carcinoma of the nasal ale 15 years after radiation. Conclusion: Conformal radiotherapy shows promise as an alternative treatment approach for locally advanced JNA and confers long-term disease control with minimal toxicity.

    Purpose: To identify prognostic factors for local and distant relapse and perform risk stratification for patients with advanced cervical cancer treated with radiotherapy (RT) alone. Methods and Materials: A total of 1031 patients with Stage IB-IVA squamous cell carcinoma of the cervix treated with full-course RT but without any chemotherapy were included for analysis. Of these, 311 patients with nonbulky Stage IB-IIA disease were designated the reference group and the other 720 patients were the study group. The associations of stage, squamous cell carcinoma antigen (SCC-ag) level, hemoglobin level, age, cell differentiation, and pelvic lymph node status with treatment failure were evaluated. The independent prognostic factors were identified by multivariate analysis. The study group was further stratified into subgroups using combinations of these risk factors. Results: In the study group, independent risk factors for local relapse were advanced stage and age 2, and positive pelvic lymph nodes. The 5-year distant relapse-free survival rate was 83% for patients with bulky Stage IB-IIA and IIB disease, SCC-ag level 2, and positive lymph nodes. Conclusion: The risk of treatment failure in advanced-stage cervical cancer patients treated by RT alone can be more precisely predicted by risk stratification. A certain subgroup of patients had better control than the others. The benefit of treating these relatively low-risk patients with additional treatment such as concurrent chemotherapy should be further evaluated in prospective studies or meta-analyses

    The objective of this study was to determine the efficacy of quad-shot radiation therapy for palliation in locally advanced and metastatic inoperable squamous cell carcinomas of head and neck. Study Design: A quasi-experimental study. Place and Duration of Study: Oncology department, Combined Military Hospital Rawalpindi, from Sep 2012 to Sep 2013. Material and Methods: Thirty five patients were included with histologically confirmed advanced inoperable squamous cell carcinoma in head and neck region, performance status 2 or 3 and survival =3 months. Patients were treated with radiation therapy 14 Gy in four fractions, megavoltage beam, twice daily fractions (at least 6 hours apart), for 2 consecutive days. Symptoms due to cancer (pain and dysphagia) were assessed as per common toxicity criteria adverse event version 4.0 on day 0 before treatment and day 21 after start of treatment. Results: Grades of pain and dysphagia showed significant improvement after treatment with a p-value <0.001. A total of 91.4% patients showed an improvement in grade of pain (32 out of 35 patients) and 45.7% of patients showed improvement in grade of dysphagia (16 out of 35 patients). There was a statistically significant decrease in grades of pain and dysphagia after treatment. Conclusion: The short duration of hypofractionated radiotherapy with Quad Shot was effective with respect to symptom palliation in locally advanced and metastatic inoperable head and neck cancers.

    Current staging systems have limited ability to adjust optimal therapy in advanced nasopharyngeal carcinoma (NPC). This study aimed to delineate the correlation between tumor volume, treatment outcome and chemotherapy cycles in advanced NPC. A retrospective review of 110 patients with stage III-IV NPC was performed. All patients were treated first with neoadjuvant chemotherapy, then concurrent chemoradiation, and followed by adjuvant chemotherapy as being the definitive therapy. Gross tumor volume of primary tumor plus retropharyngeal nodes (GTVprn) was calculated to be an index of treatment outcome. GTVprn had a close relationship with survival and recurrence in advanced NPC. Large GTVprn (≧13 ml) was associated with a significantly poorer local control, lower distant metastasis-free rate, and poorer survival. In patients with GTVprn ≧ 13 ml, overall survival was better after ≧4 cycles of chemotherapy than after less than 4 cycles. The incorporation of GTVprn can provide more information to adjust treatment strategy

    The report assesses Local Area Network Communications with a view to their application in advanced nuclear reactor control and protection systems. Attention is focussed on commercially available techniques and systems for achieving the high reliability and availability required. A basis for evaluating network characteristics in terms of broadband or baseband type, medium, topology, node structure and access method is established. The reliability and availability of networks is then discussed. Several commercial networks are briefly assessed and a distinction made between general purpose networks and those suitable for process control.

    Of 227 esophageal carcinomas treated with a radiation dose of 60 Gy or more, 100 patients had no tumor or ulceration (with or without stenosis) of the esophagus after irradiation. We analyzed local control factors of these 100 patients to determine the need for further treatment. The cumulative local control rate at five years was 40% in all cases, 37% in 21 cases without any stenosis of the esophagus and 40% in 79 cases with stenosis. The presence of stenosis of the esophagus after irradiation was not a critical factor in predicting final local control. Local recurrence of tumors with findings of Borrmann III or Borrmann IV by the pretreatment esophageal barium study, tumors controlled after a total dose of more than 80 Gy, tumors without low dose rate telecobalt therapy (LDRT: 1 Gy/hour, 5 to 7 Gy/day, a total dose of 12 to 15 Gy) as boost therapy, and apparently controlled tumors with a stenotic ratio of 60% or more or with 5 cm or more length of stenosis of the esophagus after irradiation was significantly higher than that of the others (p<0.05). Multivariate analysis revealed that findings of pretreatment barium study, total dose, with or without LDRT, and length of stenosis of the esophagus after irradiation were significantly important factors in local control. Members of the high risk group of apparently controlled tumors should undertake surgical treatment or further intensive chemotherapy. (author)

    Dramatic improvements in the outcomes of patients with rectal cancer have occurred over the past 30 years. Advances in surgical pathology, refinements in surgical techniques and instrumentation, new imaging modalities, and the widespread use of neoadjuvant therapy have all contributed to these improvements. Several questions emerge as we learn of the benefits or lack thereof for components of the current multimodality treatment in subgroups of patients with nonmetastatic locally advanced rectal cancer (LARC). What is the optimal surgical technique for distal rectal cancers? Do all patients need postoperative chemotherapy? Do all patients need radiation? Do all patients need surgery, or is a nonoperative, organ-preserving approach warranted in selected patients? Answering these questions will lead to more precise treatment regimens, based on patient and tumor characteristics, that will improve outcomes while preserving quality of life. However, the idea of shifting the treatment paradigm (chemoradiotherapy, total mesorectal excision, and adjuvant therapy) currently applied to all patients with LARC to a more individually tailored approach is controversial. The paradigm shift toward organ preservation in highly selected patients whose tumors demonstrate clinical complete response to neoadjuvant treatment is also controversial. Herein, we highlight many of the advances and resultant controversies that are likely to dominate the research agenda for LARC in the modern era. PMID:25918296

    BACKGROUND: Nivolumab, a programmed death 1 (PD-1) checkpoint inhibitor, was associated with encouraging overall survival in uncontrolled studies involving previously treated patients with advanced renal-cell carcinoma. This randomized, open-label, phase 3 study compared nivolumab with everolimus...... of nivolumab per kilogram of body weight intravenously every 2 weeks or a 10-mg everolimus tablet orally once daily. The primary end point was overall survival. The secondary end points included the objective response rate and safety. RESULTS: The median overall survival was 25.0 months (95% confidence...... interval [CI], 21.8 to not estimable) with nivolumab and 19.6 months (95% CI, 17.6 to 23.1) with everolimus. The hazard ratio for death with nivolumab versus everolimus was 0.73 (98.5% CI, 0.57 to 0.93; P=0.002), which met the prespecified criterion for superiority (P≤0.0148).

    Full Text Available RF Kokelaar, MD Evans, M Davies, DA Harris, J Beynon Department of Colorectal Surgery, Singleton Hospital, Swansea, UK Abstract: Between 5% and 10% of patients with rectal cancer present with locally advanced rectal cancer (LARC, and 10% of rectal cancers recur after surgery, of which half are limited to locoregional disease only (locally recurrent rectal cancer. Exenterative surgery offers the best long-term outcomes for patients with LARC and locally recurrent rectal cancer so long as a complete (R0 resection is achieved. Accurate preoperative multimodal staging is crucial in assessing the potential operability of advanced rectal tumors, and resectability may be enhanced with neoadjuvant therapies. Unfortunately, surgical options are limited when the tumor involves the lateral pelvic sidewall or high sacrum due to the technical challenges of achieving histological clearance, and must be balanced against the high morbidity associated with resection of the bony pelvis and significant lymphovascular structures. This group of patients is usually treated palliatively and subsequently survival is poor, which has led surgeons to seek innovative new solutions, as well as revisit previously discarded radical approaches. A small number of centers are pioneering new techniques for resection of beyond-total mesorectal excision tumors, including en bloc resections of the sciatic notch and composite resections of the first two sacral vertebrae. Despite limited experience, these new techniques offer the potential for radical treatment of previously inoperable tumors. This narrative review sets out the challenges facing the management of LARCs and discusses evolving management options. Keywords: rectal cancer, exenteration, pelvic sidewall, sacrectomy

    The diagnosis of unresectable locally advanced pancreatic adenocarcinoma (LAPC) requires confirmation, through imaging tests, of the unfeasibility of achieving a complete surgical resection, in the absence of metastatic spread. The increase in overall survival (OS), together with an appropriate symptom management is the therapeutic target in LAPC, maintaining an acceptable quality of life and, if possible, increasing the time until the appearance of metastasis. Chemoradiation (CRT) improves OS compared to best support treatment or radiotherapy (RT) but with greater toxicity. No significant increase in OS has been achieved with CRT when compared to chemotherapy (QT) alone in patients without disease progression after four months of treatment with QT. However, a significantly better local control, that is, a significant increase in the time to disease progression was associated with this approach. The greater effectiveness of the schemes FOLFIRINOX and gemcitabine (Gem) + Nab-paclitaxel compared to gemcitabine alone, has been extrapolated from metastatic disease to LAPC, representing a possible alternative for patients with good performance status (ECOG 0-1). In the absence of randomized clinical trials, Gem is the standard treatment in LAPC. If disease control is achieved after 4-6 cycles of QT, the use of CRT for consolidation can be considered an option vs QT treatment maintenance. Capecitabine has a better toxicity profile and effectiveness compared to gemcitabine as a radiosensitizer. After local progression, and without evidence of metastases, treatment with RT or CRT, in selected patients, can support to maintain the regional disease control.

    Objective: Small cell carcinoma of the uterine cervix is a rare and aggressive tumor. This tumor is similar to small cell carcinoma of the lung with a tendency to metastasize early. While there has been an increasing interest in the use of chemotherapy regimens similar to those used for small cell carcinoma of the lung, the optimum local therapy for small cell carcinoma of the cervix remains unknown. We reviewed the treatment outcome of patients with small cell carcinoma of the cervix diagnosed in our cancer center with an emphasis on the local/regional disease control. Material and Methods: Between 1983 and 1993, medical records of patients diagnosed with carcinoma of the uterine cervix were reviewed. There were 281 patients with carcinoma of the uterine cervix referred to our department for radiation treatment. Seven patients had pathologic diagnosis of either small cell or neuroendocrine histology. Details of the treatments and follow-up information of these patients were reviewed with a medium follow-up period of three years (range - 1 to 4 years). Results: Five patients had pure small cell histology. Two patients had mixed histology: one with mixed small cell anaplastic neuroendocrine cells and a small foci of adenocarcinoma, the other had mixed small cell and squamous cell histology. Four patients had clinical stage IB disease. The others had IIA, IIB, and IIIB disease, respectively. All patients received either irradiation (XRT) alone or as part of the local therapy. Three patients received XRT alone, one received surgery followed by XRT, one received XRT followed by surgery, and the remaining two had triple modality treatment (chemotherapy, surgery, and XRT). Three patients were alive without evidence of disease recurrence at the last follow-up. Two of these received adjuvant chemotherapy in addition to local therapy. The third patient, whose tumor was smaller than one cm at the time of diagnosis, received XRT alone. Four patients died with disease

    Full Text Available The past decade has seen a rapid proliferation in the number and types of systemic therapies available for renal cell carcinoma. However, surgery remains an integral component of the therapeutic armamentarium for advanced and metastatic kidney cancer. Cytoreductive surgery followed by adjuvant cytokine-based immunotherapy (predominantly high-dose interleukin 2 has largely given way to systemic-targeted therapies. Metastasectomy also has a role in carefully selected patients. Additionally, neoadjuvant systemic therapy may increase the feasibility of resecting the primary tumor, which may be beneficial for patients with locally advanced or metastatic disease. Several prospective trials examining the role of adjuvant therapy are underway. Lastly, the first immune checkpoint inhibitor was approved for metastatic renal cell carcinoma (mRCC in 2015, providing a new treatment mechanism and new opportunities for combining systemic therapy with surgery. This review discusses current and historical literature regarding the surgical management of patients with advanced and mRCC and explores approaches for optimizing patient selection.

    While the deregulation of iron homeostasis in breast epithelial cells is acknowledged, iron-related alterations in stromal inflammatory cells from the tumor microenvironment have not been explored. Immunohistochemistry for hepcidin, ferroportin 1 (FPN1), transferrin receptor 1 (TFR1) and ferritin (FT) was performed in primary breast tissues and axillary lymph nodes in order to dissect the iron-profiles of epithelial cells, lymphocytes and macrophages. Furthermore, breast carcinoma core biopsies frozen in optimum cutting temperature (OCT) compound were subjected to imaging flow cytometry to confirm FPN1 expression in the cell types previously evaluated and determine its cellular localization. We confirm previous results by showing that breast cancer epithelial cells present an ‘iron-utilization phenotype’ with an increased expression of hepcidin and TFR1, and decreased expression of FT. On the other hand, lymphocytes and macrophages infiltrating primary tumors and from metastized lymph nodes display an ‘iron-donor’ phenotype, with increased expression of FPN1 and FT, concomitant with an activation profile reflected by a higher expression of TFR1 and hepcidin. A higher percentage of breast carcinomas, compared to control mastectomy samples, present iron accumulation in stromal inflammatory cells, suggesting that these cells may constitute an effective tissue iron reservoir. Additionally, not only the deregulated expression of iron-related proteins in epithelial cells, but also on lymphocytes and macrophages, are associated with clinicopathological markers of breast cancer poor prognosis, such as negative hormone receptor status and tumor size. The present results reinforce the importance of analyzing the tumor microenvironment in breast cancer, extending the contribution of immune cells to local iron homeostasis in the tumor microenvironment context

    Full Text Available The present therapy for primary hepatocellular carcinoma (HCC consists of surgery as well as local radiotherapy and chemotherapy. However, the majority of patients are susceptible to recurrence after comprehensive treatment, and the overall treatment outcome is not ideal due to the lack of effective drugs and strategies. Increasing evidence has demonstrated that the immune system is closely related to the development, progression, metastasis, and recurrence of HCC. Thus, immune therapy, especially cellular immunotherapy, could regulate immune function and induce specific antitumor immunity to achieve the goal of controlling HCC and reducing its recurrence and metastasis, which has become an essential part in the comprehensive treatment of HCC. The findings in preclinical and clinical studies on cellular immunotherapy for HCC data are reviewed, and the current problems are discussed.

    The survival of patients with unresectable advanced hepatocellular carcinoma (HCC) with portal vein thrombosis is dismal. Current therapeutic options have limited efficacy. Vitamin K has been shown to have antitumor effect on HCC cells both in cell lines and patients with advanced HCC. The aim of this study was to assess the clinical efficacy of high dose vitamin K3 in the treatment of advanced HCC with portal vein thrombosis. Forty-two consecutive patients with advanced HCC (Stage C according to BCLC staging system) with portal vein thrombosis were randomized into two groups: (i) high dose vitamin K3 (n = 23); and (ii) placebo (n = 19). The vitamin K3 was administered by i.v. infusion of 50 mg/day with daily increase of dose by 50 mg for 6 days, followed by 20 mg i.m. twice daily for 2 weeks. Of the 23 patients treated with vitamin K, one (4.3%) achieved complete response and three (13%) partial response, for a total of four (17.4%) objective responders overall. The overall mean survival was 8.9 +/- 8.8 months (median: 6; range 1-37 months) in the vitamin K group and 6.8 +/- 5.3 months (median: 5; range 1.5-21 months) in the placebo group (P = 0.552). The mean duration of survival was longer in patients in the vitamin K group who achieved objective response (22.5 +/- 12.2; median: 21; range 11-37 months) as compared to patients not achieving objective response (6.1 +/- 4.6; median: 5; range 1-16 months) (P = 0.0.002). Portal vein thrombosis resolved with complete patency in one (4.35%) patient. Treatment with high dose vitamin K produces objective response in 17% patients with improved survival in patients achieving objective response; however, it does not affect the overall survival.

    Renal cell carcinoma (RCC) continues to increase in incidence with the largest increase manifesting in small, organ-confined tumors. This review outlines the epidemiology and current data pertaining to the management of clinically-localized RCC. In this manuscript, the current data outlining the benefit of nephron sparing to the overall survival of the patient is described. The data pertaining to minimally invasive nephron sparing is also explained in detail. From laparoscopic and robotic partial nephrectomy to watchful waiting and percutaneous ablation, the urologist is continually assaulted with new data for the management of clinically-localized RCC. The data can be confusing, and much of it is conflicting. The addition of new scoring systems or nomograms may aid in predicting which therapy would be most beneficial in certain patient groups. New scoring systems may also predict the difficulty of surgical resection and predict surgical complications. The limitations of the data pertaining to the management of clinically-localized RCC are also outlined.

    Merkel Cell Carcinoma (MCC) is a rare and aggressive tumour, arising from a cutaneous mechanoceptor cell located in the basal layer of epidermis, with poor prognosis. The treatment of choice for the initial stage of the disease is surgery and/or radiotherapy. The treatment of recurrent or advanced disease is still controversial. We report a case of 84 years old woman with a recurrent MCC of the chin treated with electrochemotherapy (ECT). During the period of 20 months, four sessions of ECT were employed, which resulted in an objective response of the tumour and good quality of residual life. Our case shows the effectiveness of ECT in the treatment of locally advanced MCC of the head and neck region in a patient not suitable for standard therapeutic options

    The outcome of 42 patients who developed locally recurrent rectal carcinoma after initial local excision or electrocoagulation was presented. Five patients received combined surgery and radiotherapy (XRT). The remaining 37 patients were managed by XRT alone. The overall 5 years actuarial survival and local control rates were 21 and 22 percent, respectively. For patients who received XRT alone, the 5 year actuarial survival and local control rates were 20 and 15 percent, resp. The corresponding figures were 35 and 40 percent for patients who received a total XRT dose of 50 Gy or more. One patient who underwent combined treatment developed rectal and bladder incontinence requiring surgery. For patients with rectal recurrence after initial conservative surgery, XRT is an alternative to abdominoperipheral resection if major resection is contraindicated. (author). 13 refs.; 2 tabs

We evaluated the efficacy and safety of a partially completed chemoradiation regimen prescribed for locally advanced carcinoma of the cervix. Methods: Medical records of 156 patients with locally advanced cervical cancer stage IIB–IVA who received chemoradiation with cisplatin (40 mg/m2 and 5-fluorouracil (500 mg/m2 from October 2006 to October 2008 were collected. The treatment protocol called for two cycles of chemotherapy. External beam radiation therapy was administered using a 10-MeV electron beam. Local control, disease free survival, overall survival, and toxicities were evaluated. Results: With a median follow-up of 37.5 months, 89 patients (57% completed the planned protocol. Sixty seven patients (43% completed fewer than two cycles. The 3-year local control rate was significantly better in the patient group that completed the prescribed plan (92.1% compared to 80.6%; P = 0.033. No statistical significance was observed between the groups that completed or did not complete the two cycle protocol with regard to disease free survival (80.9% and 73.2%, respectively; P = 0.250, overall survival (84.3% and 79.1%; P = 0.405, and progression survival (3.4% and 3.0%; P = 0.892. Differences in acute hematologic toxicity and subcutaneous toxicity were observed between the two groups. Conclusions: Completion of two cycles of 5-fluorouracil and cisplatin with radiotherapy was effective, safe, and responsible for better local control

    Most patients with hepatocellular carcinoma present with intermediate to advanced disease, where curative therapies are no longer an option. These patients with intermediate to advanced disease represent a heterogeneous population with regard to tumor burden, liver function, and performance status. While the Barcelona Clinic Liver Cancer (BCLC) staging system offers guidelines for the management of these patients, strict adherence to these guidelines may limit treatment options for these patients. Several locoregional therapies exist for these patients, including conventional transarterial chemoembolization (cTACE), transarterial embolization (TAE), drug-eluting embolization (DEE), and radioembolization. Evidence is also emerging for the role of radiation therapy including most notably stereotactic body radiation therapy and proton therapy, although at the current time, clinical trial participation is encouraged. While cTACE is traditionally recommended for BCLC B disease, both cTACE and radioembolization are increasingly used for patients with intermediate disease, as well as in select patients with BCLC A and C disease. TAE and DEE are limited in their use currently, due to lack of clear survival benefits or clinical advantages over cTACE. While several studies have demonstrated similar OS between cTACE and radioembolization, radioembolization provides a longer time to progression and fewer toxicities compared to cTACE. This is particularly relevant in the setting of advanced BCLC B and early BCLC C disease, where patients may have limited reserve. Radioembolization also has additional roles as an alternative to ablation, inducing liver hypertrophy, treating patients with PVT, and downstaging lesions to transplant. Ongoing studies will further define the role of locoregional treatment potentially in combination with and in light of developments in systemic therapy.

    Purpose: To study the effects of midcourse treatment break or gaps related to the local control of T3 carcinoma of the oropharynx and larynx following accelerated hyperfractionated radiation therapy. Methods and Materials: All patients were treated at the Massachusetts General Hospital from 1979 through 1994 with treatment consisting of 1.6 Gy per fraction, two fractions a day for the treatment of T3 carcinoma of the oropharynx and larynx. They were entered in the head and neck data base. Their treatment dates, treatment breaks, and doses vs. local control were analyzed and compared. A p-value of 0.05 was considered statistically significant. Results: A total of 162 patients were available for review. Due to the acute severe mucosal effects, most of the patients required a midcourse pause or 'break' after a dose of 38.4-48 Gy before treatment could be resumed and completed. The data indicate that (a) prolongation of the treatment gap for more than 14 days, (b) total treatment course longer than 45 days, (c) total dose less than 67 Gy, and (d) male gender adversely affected local control. In spite of the gaps, the female patients with advanced carcinomas enjoyed the benefits of improved local control after the accelerated hyperfractionated radiation therapy. Conclusions: Accelerated hyperfractionation radiation therapy using 1.6 Gy per fraction/twice-a-day (b.i.d.) for a total dose of 70.4 Gy in 6 weeks is effective in achieving high local control of T3 squamous cell carcinoma of the oropharynx and larynx. The midcourse treatment gap should be as short as possible with the projected total dose and time. Should the gaps be unduly prolonged due to various circumstances, further increase in the total dose, for example, 72-75 Gy, and/or increase of the fraction sizes, for example, 1.8-2.0 Gy/f b.i.d. after the gap may be necessary to compensate for the adverse effects of the tumor regeneration from the prolonged gap

    Full Text Available Advanced hepatocellular carcinoma (HCC remains a fatal disease even in the era of targeted therapies. Intra-arterial chemotherapy (IACT can provide therapeutic benefits for patients with locally advanced HCC who are not eligible for local therapies or are refractory to targeted therapies. The aim of this retrospective study was to analyze the effect of IACT with cisplatin and doxorubicin on advanced HCC. Methods. Patients with advanced HCC who were not eligible for local therapies or were refractory to sorafenib received doxorubicin (50 mg/m2 and cisplatin (50 mg/m2 infusions into the liver via the transhepatic artery. Between January 2005 and December 2011, a total of 50 patients with advanced HCC received this treatment regimen. The overall response rate (ORR was 22% in all treated patients. In patients who received at least 2 cycles of IACT, the ORR was 36.7%, and the disease control rate was 70%. Survival rate differed significantly between patients who received only one cycle of IACT (group I and those who received several cycles (group II. The median progression-free survival was 1.3 months and 5.8 months in groups I and II, respectively (P<0.0001. The median overall survival was 8.3 months for all patients and was 3.1 months and 12.0 months in groups I and II, respectively (P<0.0001. The most common toxicity was alopecia. Four patients developed grade 3 or 4 leukopenia. Worsening of liver function, nausea, and vomiting were uncommon side effects. This study demonstrated clinical efficacy and tolerable side effects of repeated IACT with doxorubicin and cisplatin in advanced HCC. Our regimen can be an alternative choice for patients with adequate liver function who do not want to receive continuous infusion of IACT.

    The glycoprotein CD147 has a role in tumor progression, is readily detectable in the circulation, and is abundantly expressed in hepatocellular carcinoma (HCC). Advanced HCC patients are a heterogeneous group with some individuals having dismal survival. The aim of this study was to examine circulating soluble CD147 levels as a prognostic marker in HCC patients. CD147 was measured in 277 patients (110 HCC, 115 chronic liver disease, and 52 non-liver disease). Clinical data included etiology, tumor progression, Barcelona Clinic Liver Cancer (BCLC) stage, and treatment response. Patients with HCC were stratified into two groups based upon the 75th percentile of CD147 levels (24 ng/mL). CD147 in HCC correlated inversely with poor survival (P = 0.031). Increased CD147 predicted poor survival in BCLC stages C and D (P = 0.045), and CD147 levels >24 ng/mL predicted a significantly diminished 90-day and 180-day survival time (hazard ratio [HR] = 6.1; 95% confidence interval [CI]: 2.1-63.2; P = 0.0045 and HR = 2.8; 95% CI: 1.2-12.6; P = 0.028, respectively). In BCLC stage C, CD147 predicted prognosis; levels >24 ng/mL were associated with a median survival of 1.5 months compared with 6.5 months with CD147 levels ≤24 ng/mL (P = 0.03). CD147 also identified patients with a poor prognosis independent from treatment frequency, modality, and tumor size. Circulating CD147 is an independent marker of survival in advanced HCC. CD147 requires further evaluation as a potential new prognostic measure in HCC to identify patients with advanced disease who have a poor prognosis. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Our primary objective was to determine if [{sup 18}F]FPRGD{sub 2} PET/CT performed at baseline and/or after chemoradiotherapy (CRT) could predict tumour regression grade (TRG) in locally advanced rectal cancer (LARC). Secondary objectives were to compare baseline [{sup 18}F]FPRGD{sub 2} and [{sup 18}F]FDG uptake, to evaluate the correlation between posttreatment [{sup 18}F]FPRGD{sub 2} uptake and tumour microvessel density (MVD) and to determine if [{sup 18}F]FPRGD{sub 2} and FDG PET/CT could predict disease-free survival. Baseline [{sup 18}F]FPRGD{sub 2} and FDG PET/CT were performed in 32 consecutive patients (23 men, 9 women; mean age 63 ± 8 years) with LARC before starting any therapy. A posttreatment [{sup 18}F]FPRGD{sub 2} PET/CT scan was performed in 24 patients after the end of CRT (median interval 7 weeks, range 3 - 15 weeks) and before surgery (median interval 4 days, range 1 - 15 days). All LARC showed uptake of both [{sup 18}F]FPRGD{sub 2} (SUV{sub max} 5.4 ± 1.5, range 2.7 - 9) and FDG (SUV{sub max} 16.5 ± 8, range 7.1 - 36.5). There was a moderate positive correlation between [{sup 18}F]FPRGD{sub 2} and FDG SUV{sub max} (Pearson's r = 0.49, p = 0.0026). There was a moderate negative correlation between baseline [{sup 18}F]FPRGD{sub 2} SUV{sub max} and the TRG (Spearman's r = -0.37, p = 0.037), and a [{sup 18}F]FPRGD{sub 2} SUV{sub max} of >5.6 identified all patients with a complete response (TRG 0; AUC 0.84, 95 % CI 0.68 - 1, p = 0.029). In the 24 patients who underwent a posttreatment [{sup 18}F]FPRGD{sub 2} PET/CT scan the response index, calculated as [(SUV{sub max}1 - SUV{sub max}2)/SUV{sub max}1] x 100 %, was not associated with TRG. Post-treatment [{sup 18}F]FPRGD{sub 2} uptake was not correlated with tumour MVD. Neither [{sup 18}F]FPRGD{sub 2} nor FDG uptake predicted disease-free survival. Baseline [{sup 18}F]FPRGD{sub 2} uptake was correlated with the pathological response in patients with LARC treated with CRT. However, the

    Full Text Available A 37-year-old male athlete was diagnosed with primary tracheal adenoid cystic carcinoma following investigation for dyspnea, wheeze, and eventual stridor. Preoperative bronchoscopy revealed a highly vascular tumor 4 cm distal to the cricoid with no gross disease extending to the carina. Imaging revealed circumferential tracheal irregularity immediately inferior to the cricoid, with no definite cricoid invasion. Locoregional extension of disease was noted invading the thyroid and abutment of the carotid approximately 180°. Intraoperative findings identified tracheal mucosal disease extending distal to the carina and proximally at the cricothyroid joints where bilateral functional recurrent nerves were preserved. A decision made to preserve the larynx given the inability to fully resect distal tracheal disease. A 5 cm sleeve resection of the trachea was made with a cricotracheal anastomosis following suprahyoidal muscle release and laryngeal drop-down. The patient was treated with adjuvant radiotherapy including platinum based chemotherapy in an effort to maximise local control. PET scanning three months after therapy revealed no FDG uptake locally or distally.

    The purpose of this study was to evaluate the efficacy and toxicity of docetaxel as single-agent neoadjuvant chemotherapy in locoregionally advanced cervical carcinoma. Between April 1998 and August 2000, 38 untreated patients with International Federation of Gynecology and Obstetrics stages IIB to IVA were entered onto this study. The median age was 44 years (range: 25-66 years). Stages: IIB 22 patients, IIIB 15 patients, and IVA 1 pt. Treatment consisted of docetaxel 100 mg/m2 IV infusion during 1 hour. Standard premedication with dexamethasone, diphenhydramine, and ranitidine was used. Cycles were repeated every 3 weeks for three courses, followed by radical surgery when it was judged appropriate, or definitive radiotherapy. Both staging and response assessment were performed by a multidisciplinary team. 106 cycles of therapy were administered; all patients were evaluable for TX, whereas 35 were evaluable for response (3 patients refused further treatment after the first cycle of therapy). Complete response (CR): 1 patient (3%); partial response: 11 patients (31%), for an overall objective response rate of 34% (95% CI: 15-53%); no change (NC): 16 patients (46%); and progressive disease: 7 patients (20%). Six patients (17%) underwent surgery and a pathologic CR was confirmed in 1 of them. The median time to treatment failure and the median survival have not been reached yet. The limiting toxicity was leukopenia in 25 patients (69%) (G1-G2: 14 patients, G3: 10 patients, and G4: 1 patient). Neutropenia: 28 patients (78%) (G1-G2: 10 patients, G3: 8 and G4: 10). Myalgias: 17 patients (47%) (G1-G2: 15 patients and G3: 2 patients). Emesis: 21 patients (55%) (G1-G2: 19 patients and G3: 2 patients). Alopecia G3: 13 patients (36%); rash cutaneous 26 patients (68%) (G1-G2: 22 patients and G3: 4 patients). There were no hypersensitivity reactions or fluid-retention syndrome. The received dose intensity was 91% of that projected. Docetaxel is an active drug against advanced

    To examine toxicity and outcomes for patients treated with preoperative chemoradiotherapy (CRT) for gastric cancer. Patients with gastroesophageal (GE) junction (Siewert type II and III) or gastric adenocarcinoma who underwent neoadjuvant CRT followed by planned surgical resection at Duke University between 1987 and 2009 were reviewed. Overall survival (OS), local control (LC) and disease-free survival (DFS) were estimated using the Kaplan-Meier method. Toxicity was graded according to the Common Toxicity Criteria for Adverse Events version 4.0. Forty-eight patients were included. Most (73%) had proximal (GE junction, cardia and fundus) tumors. Median radiation therapy dose was 45 Gy. All patients received concurrent chemotherapy. Thirty-six patients (75%) underwent surgery. Pathologic complete response and R0 resection rates were 19% and 86%, respectively. Thirty-day surgical mortality was 6%. At 42 months median follow-up, 3-year actuarial OS was 40%. For patients undergoing surgery, 3-year OS, LC and DFS were 50%, 73% and 41%, respectively. Preoperative CRT for gastric cancer is well tolerated with acceptable rates of perioperative morbidity and mortality. In this patient cohort with primarily advanced disease, OS, LC and DFS rates in resected patients are comparable to similarly staged, adjuvantly treated patients in randomized trials. Further study comparing neoadjuvant CRT to standard treatment approaches for gastric cancer is indicated

    AIM: To investigate the efficacy of hepatic arterial infusion chemotherapy (HAIC) using floxuridine (FUDR) in patients with advanced hepatocellular carcinoma (HCC) confined to the liver. METHODS: Thirty-four patients who had advanced HCC with unresectability or unsuccessful previous therapy in the absence of extrahepatic metastasis were treated with intra-arterial FUDR chemotherapy at our hospital between March 2005 and May 2008. Among the 34 patients, 9 patients were classified as Child class C, and 18 patients had portal vein tumor thrombus (PVTT). One course of chemotherapy consisted of continuous infusion of FUDR (0.3 mg/kg during day 1-14) and dexamethasone (10 mg on day 1, 4, 7 and 11), and this treatment was repeated every 28 d. RESULTS: Two patients (5.9%) displayed a complete response, and 12 patients (35.3%) had a partial response. The tumor control rate was 61.8%. The median overall survival times were 15.3 mo, 12.4 mo and 4.3 mo for the patients who were classified as Child class A, Child class B and Child class C, respectively (P = 0.0392). The progression-free survival was 12.9 mo, 7.7 mo and 2.6 mo for the patients who were classified as Child class A, Child class B and Child class C, respectively (P = 0.0443). The cumulative survival differed significantly according to the Child-Pugh classification and the presence of PVTT. In addition to hepatic reserve capacity and PVTT, the extent of HCC was an independent factor in determining a poor prognosis. The most common adverse reactions to HAIC were mucositis, diarrhea and peptic ulcer disease, but most of these complications were improved by medical treatment and/or a delay of HAIC. CONCLUSION: The present study demonstrates that intra-arterial FUDR chemotherapy is a safe and effective treatment for advanced HCC that is recalcitrant to other therapeutic modalities, even in patients with advanced cirrhosis.

    Medullary thyroid carcinoma (MTC) comprises approximately 4% of all malignant thyroid neoplasms. Although the majority of patients have a good prognosis, a subgroup of patients develops progressive disease and requires systemic therapy. Here, we focused on the current MTC therapeutic approaches and discussed the advantages and disadvantages of molecular targeted therapies. Targeted molecular therapies that inhibit RET and other tyrosine kinase receptors involved in angiogenesis have been shown to improve progression-free survival in patients with advanced MTC. Two drugs, vandetanib and cabozantinib, have been approved for the treatment of progressive or symptomatic MTC, and several others have exhibited variable efficacy. No tyrosine kinase inhibitor has been shown to improve survival. Although no definitive recommendation can currently be made, cumulative data indicate that knowledge of the tumor mutational profile may facilitate improvements in targeted therapy for MTC. Tyrosine kinase inhibitors are effective therapeutic agents for the treatment of progressive MTC. Nevertheless, it is not clear who will benefit the most from therapy, and the decision regarding when and how to initiate the treatment should be made based on the patient's medical history and tumor behavior. Hopefully, in the near future, molecular profiling of MTC can be used to determine the most effective molecular therapeutic target.

    Advanced urothelial carcinoma (aUC) has long been treated preferably with cisplatin-based chemotherapy, but many patients are cisplatin-ineligible whereas for those who progress on a platinum-based regimen treatment options are limited. We review key recent data regarding immune checkpoint inhibitors that are changing this treatment landscape. Since May 2016, five different agents targeting the PD-1/PD-L1 pathway (atezolizumab, pembrolizumab, nivolumab, avelumab, durvalumab) have received FDA approval for the treatment of aUC in the platinum-refractory setting, while pembrolizumab and atezolizumab are FDA-approved for cisplatin-ineligible patients in the first-line setting. Clinical outcomes and safety profiles of these agents appear relatively comparable across separate trials; however, only pembrolizumab is supported by level I evidence from a large randomized phase III trial showing overall survival benefit over conventional cytotoxic salvage chemotherapy in the platinum-refractory setting. Pembrolizumab has the highest level of evidence in platinum-refractory aUC, whereas pembrolizumab and atezolizumab have comparable level of evidence in the frontline setting in cisplatin-ineligible patients. Ongoing research is evaluating novel agents, various rational combinations, and sequences, as well as predictive and prognostic biomarkers.

    The Hedgehog pathway has been identified as a key element in the development of many forms of cancer. Smoothened (Smo) inhibitors are known to beneficially interfere with the Hedgehog pathway and are currently under investigation as anticancer drugs for many tumor entities. Reviewed here are the most recent developments in clinical research on Smo inhibitors for the treatment of advanced basal cell carcinoma (BCC). When reviewing the literature of the past 12 months, it is striking to see the rapid evolution of the field. Compounds that have been presented as powerful new drug candidates 12 months ago have now been discontinued, whereas new ones have emerged. Reports on 13 drug candidates have been identified: one marketed, vismodegib, eight currently under development (phase I-II) and four for which clinical investigation for BCC is currently not being pursued. Smo inhibitors are a promising drug class for the treatment of BCC. To date, most candidates are in early stage development and are expected to enter the market in approximately 5-8 years, if successful.

    A phase II trial was performed to evaluate the efficacy and toxicity of a combination of cisplatin (CDDP) and ifosfamide (IFX) as neoadjuvant chemotherapy in advanced cervical carcinoma (ACC). Between August 1991 and September 1993, 57 untreated patients with stages IIB to IVA were entered into this study. Median age was 44 years (range, 25 to 74 years). The distribution by stages (International Federation of Gynecology and Obstetrics) was as follows: IIB, 31 patients; IIIB, 21 patients; and IVA, 5 patients. Therapy consisted of IFX 2000 mg/m(2) 1-h i.v. infusion days 1 to 3; mesna 400 mg/m(2) i.v. bolus at hours 0 and 4, and 800 mg p.o. at hour 8; and CDDP 100 mg/m(2) on day 3. Cycles were repeated every 28 days for a total of three courses. Both staging and response assessment were performed by a multidisciplinary team. An objective response was observed in 30 of 56 patients (54%; 95% confidence interval, 41 to 67%). Four patients (7%) had a complete response (CR) and 26(46%) had a partial response (PR). Patients with CR or operable PR underwent surgery, otherwise received definitive radiotherapy. Toxicity was mild to moderate. There were no toxicity related deaths. These results indicate that IFX/CDDP is an active combination for ACC with mild toxicity. The results of phase III studies that evaluate the real impact of neoadjuvant chemotherapy are awaited.

    We report our institutional observations of ten patients with advanced hepatocellular carcinoma (HCC) (seven and three were Child-Pugh class A and B, respectively) who received compassionate regorafenib therapy between June 2016 and January 2017. These patients did not fit the rigid criteria of a clinical trial and represented the use of regorafenib in an everyday clinic situation. Regorafenib (160 mg P.O. daily) was administered to patients on a 4-week cycle (3 weeks on, 1 week off) until disease progression (assessed using mRECIST criteria) or discontinuation secondary to toxicity (assessed using CTCAE criteria). Relevant clinical data were abstracted from patient medical records and reviewed retrospectively. The median duration of patient treatment was 6.6 weeks, and the median time to disease progression was 12.5 weeks. Most common treatment emergent adverse events were fatigue, diarrhea, and hand-foot skin reaction. Elevated AST and ALT were the most commonly observed laboratory-assessed adverse events, which reached grade 3 status in the Child-Pugh class B patients only. We observed intolerance to regorafenib treatment in one patient who had previously received a liver transplant. We also saw lithium toxicity in one patient receiving long-term lithium treatment, suggesting a potential and unexpected drug-drug interaction with regorafenib. Taken together, our observations indicate that regorafenib is beneficial in the treatment of patients with advanced HCC who progressed on or demonstrated intolerance to sorafenib therapy; however, careful selection and close monitoring of patients is necessary to maximize the benefit while minimizing the toxicities of regorafenib treatment.

    1997-01-01

    Purpose: The Dutch Head and Neck Oncology Cooperative Group, in which head and neck groups of all University hospitals and the two cancer institutes are represented, initiated a retrospective study concerning salivary gland carcinomas. A majority of Dutch patients with head and neck carcinomas are treated in the participating centres, and the follow-up is precise. Prognostic factors for local control and survival were studied, with special interest in the role of treatment and the role of histologic type. Methods and materials: Results were obtained of 568 patients with a mean follow-up time of 5 years. The parotid gland was involved in 59%, the submandibular gland in 14%, oral cavity in 24% and 3% was located elsewhere. Mean age was 59 years (range 8-100 yr), 48% was female. T-stage was T 1 in 27%, T 2 in 44%, T 3 in 19% and T 4 in 11%. Positive necknodes were seen in 15%, 3% was initially M 1 . Histologic type was acinic cell carcinoma in 12%, mucoepidermoid ca. in 16%, adenoid cystic ca. in 26%, adenoca. in 24%, carcinoma in pleomorphic adenoma in 8%, squamous cell ca. in 6% and undifferentiated ca. in 7%. Resection margins were radical in 37%, close in 20% and irradical in 40% (3% unknown). Surgery was the primary treatment in 501 patients, combined with postoperative radiotherapy (50-70 Gy, mean dose 62 Gy) in 389 patients. Radiotherapy was the primary treatment in 40 patients (18 M 1 , 30% N+), 20 patients were not treated and 7 patients were treated otherwise. For statistical analysis the Cox PH regression analysis was used (SPSS-PC+). Results: Actuarial local control after 8 years was 80% for surgery alone and 92% for the combined modality (in which more advanced cases prevaled). Independent factors for local control in the surgery±radiotherapy group were: I:T-stage (T 3 vs T 1-2 : RR 3.7; T 4 vs T 1-2 : RR 11.7), II: anatomic site (oral cavity vs parotid and submandibular gland: RR 0.2) and III: treatment modality (surgery alone vs surgery

    Purpose: To evaluate the response to local radiotherapy (RT) for unresectable hepatocellular carcinoma (HCC) and to analyze the dose-response relationship and the treatment-related morbidities. Methods and materials: Between 1998 and 2002, 59 patients who were treated with localized RT were evaluated. RT was delivered with a curative intent, and the radiation dose was 30-55 Gy (biologic effective dose of 39.0-70.2 Gy 10 using the α/β ratio of 10 Gy) with 2-3 Gy as a daily dose. The tumor response was evaluated by the change in maximum tumor size on serial CT scans, and the morbidity was evaluated by the Common Terminology Criteria for Adverse Events v3.0. Results: An objective tumor response was achieved in 39 of 59 patients (66.1%) with complete response (CR) in 5 patients and partial response (PR) in 34 patients. More than 50 Gy 10 had a significant response; CR or PR was 72.8% with >50 Gy 10 and 46.7% with ≤50 Gy 10 (p = 0.0299). The 2-year overall survival rate after RT was 27.4% (median survival time: 10 months), and this was affected by the tumor response (p = 0.0640); the 2-year overall survival rate after RT was 50.0% for CR and 21.8% for PR. There was no Grade 3 or 4 acute toxicity, and 3 patients (5.1%) developed gastric or duodenal ulcer. Conclusions: Radiotherapy for unresectable HCC resulted in 66.1% of tumor response with acceptable toxicity, and the radiation dose seems to be a significant prognostic factor in RT response for HCC

    Purpose: To study the treatment outcome in patients with locally recurrent nasopharyngeal carcinoma (NPC) and to explore whether a combination of high-dose-rate (HDR) intracavitary brachytherapy and external beam radiation therapy (ERT) could improve the therapeutic ratio. Methods and Materials: Ninety-one patients with nonmetastatic locally recurrent NPC who were treated with curative intent during the years 1990-1999 were retrospectively analyzed. Eighty-two patients had histologically proven carcinoma. The remaining 9 had clinical and imaging features suggestive of local recurrence. The Ho's T-stage distribution at recurrence (rT) was as follows: rT1-37, rT2-14, rT3-40. Total equivalent dose (TED) was calculated by the linear-quadratic formula without a time factor correction. For those treated by combined-modality treatment (CMT), the TED was taken as the summation of the equivalent dose by ERT and the absolute dose delivered to floor of the sphenoid by brachytherapy. Eight patients were treated solely with brachytherapy, all receiving 24-45 Gy in 3-10 sessions. Forty-one patients were treated with ERT alone receiving a median TED of 57.3 Gy (range, 49.8-62.5 Gy). Forty-two patients were treated by CMT with a median equivalent dose of 50 Gy (range, 40-60 Gy) given by ERT and 14.8 Gy by brachytherapy (range, 3-29.6 Gy). Multivariate analyses were performed using the Cox regression proportional hazards model. Results: The 5-year actuarial overall survival rate, disease specific survival rate and local failure-free survival (LFFS) rate for the whole group were 30%, 33.3% and 37.8%, respectively. The 3-year LFFS rates of rT1, rT2, and rT3 diseases were 64%, 61.5%, and 18.4%, respectively (p = 0.001). Of the 8 patients treated with brachytherapy alone, 4 failed locally. Further analyses were concentrated on the ERT (41 patients) and CMT (42 patients) groups. The 3-year LFFS rates of rT1, rT2, and rT3 diseases were 66.7%, 66.7%, and 18.4%, respectively (p 0

    To evaluate how many patients could have undergone partial nephrectomy (PN) rather than radical nephrectomy (RN) before and after neoadjuvant axitinib therapy, as assessed by five independent urological oncologists, and to study the variability of inter-observer agreement. Pre- and post-systemic treatment computed tomography scans from 22 patients with clear cell renal cell carcinoma in a phase II neoadjuvant axitinib trial were reviewed by five independent urological oncologists. R.E.N.A.L. nephrometry score and κ statistics were calculated. The median R.E.N.A.L. nephrometry score changed from 11 before treatment to 10 after treatment (P = 0.002). Five tumours with moderate complexity before axitinib treatment remained moderate complexity after treatment. Of 17 tumours with high complexity before axitinib treatment, three became moderate complexity after treatment. The overall κ statistic was 0.611. Moderate-complexity κ was 0.611 vs a high-complexity κ of 0.428. Before axitinib treatment the κ was 0.550 vs 0.609 after treatment. After treatment with axitinib, all five reviewers agreed that only five patients required RN (instead of eight before treatment) and that 10 patients could now undergo PN (instead of three before treatment). The odds of PN feasibility were 22.8-times higher after treatment with axitinib. There is considerable variability in inter-observer agreement on the feasibility of PN in patients treated with neoadjuvant targeted therapy. Although more patients were candidates for PN after neoadjuvant axitinib therapy, it remains difficult to identify these patients a priori. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    To clarify whether mutations in the large T gene encoded by Merkel cell polyomavirus affect the expression and function of large T antigen in Merkel cell carcinoma cases, we investigated the expression of large T antigen in vitro and in vivo. Immunohistochemistry using a rabbit polyclonal antibody revealed that large T antigen was expressed in the nuclei of Merkel cell carcinoma cells with Merkel cell polyomavirus infection. Deletion mutant analyses identified an Arg-Lys-Arg-Lys sequence (amino acids 277-280) as a nuclear localization signal in large T antigen. Sequence analyses revealed that there were no mutations in the nuclear localization signal in any of the eleven Merkel cell polyomavirus strains examined. Furthermore, stop codons were not observed in the upstream of the nuclear localization signal in any of the Merkel cell carcinoma cases examined. These data suggest that the nuclear localization signal is highly conserved and functional in Merkel cell carcinoma cases.

    Leucopenia or neutropenia during chemotherapy predicts better survival in several cancers. We aimed to assess whether leucopenia could be a biological measure of treatment and a marker of efficacy in advanced nasopharyngeal carcinoma (ANPC). We retrospectively analyzed 3826 patients with ANPC who received chemoradiotherapy. Leucopenia was categorised on the basis of worst grade during treatment according to the National Cancer Institute Common Toxicity Criteria version 4.0: no leucopenia (grade 0), mild leucopenia (grade 1–2), and severe leucopenia (grade 3–4). Associations between leucopenia and survival were estimated by Cox proportional hazards model. Of the 3826 patients, 2511 (65.6 %) developed mild leucopenia (grade 1–2) and 807 (21.1 %) developed severe leucopenia (grade 3–4) during treatment; 508 (13.3 %) did not. A multivariate Cox model that included leucopenia determined that the hazard ratios (HR) of death for patients with mild and severe leucopenia were 0.69 [95 % confidence interval (95 %CI) 0.56-0.85, p < 0.001] and 0.75 (95 %CI 0.59-0.95, p = 0.019), respectively; the HR of distant metastasis for patients with mild and severe leucopenia were 0.77 (95 %CI 0.61-0.96, p = 0.023) and 0.99 (95 %CI 0.77-1.29, p = 0.995), respectively. Leucopenia had no effect on locoregional relapse. Our results indicate that mild leucopenia during chemoradiotherapy is associated with improved overall survival and distant metastasis–free survival in ANPC. Mild leucopenia may indicate appropriate dosage of chemotherapy. We can identify the patients who may benefit from chemotherapy if they experienced leucopenia during the treatment. Prospective trials are required to assess whether dosing adjustments based on leucopenia may improve chemotherapy efficacy

    One hundred and sixteen patients with advanced ovarian carcinoma, who underwent primary cytoreductive surgery, received 6-11 courses of chemotherapy by cis-platin (50 mg/m2) and adriamycin (50 mg/m2) every 21 days. This was followed by second look laparotomy in 66 patients with no clinical evidence of disease. Consolidation abdominal irradiation was administered to 43 patients. Two techniques of irradiation were employed: between 1980-1983 whole abdominal irradiation was used and patients were to receive 3000 cGy in 4 weeks (Schedule I). Due to myelosuppression only 13 of 26 patients (50%) completed the planned dose of radiation. Between 1983-1985 the target volume was divided into upper and lower parts. First, the lower abdomen received 3000 cGy in 3 weeks, and then the upper abdomen received the same dose (Schedule II). Sixteen of seventeen patients (94%) thus treated, completed the planned dose of radiation. The actuarial survival for all 116 patients was 28% of 5 years. Irradiated patients with negative second look laparotomy had a survival probability of 100% at 24 months. Irradiated patients with microscopic disease at second look operation had an actuarial 5-year survival of 66%. Patients with minimal residual disease at second look laparotomy, receiving consolidation abdominal irradiation, had an actuarial survival of 5% only at 36 months. It is concluded that consolidation radiotherapy is effective in patients with negative or microscopic residual disease at second-look laparotomy. In regard to bone marrow tolerance, split field technique of irradiation is preferred

    A phase II trial was conducted to evaluate the efficacy and toxicity of a modulation of 5-fluorouracil (5-FU) by methotrexate (MTX) (with leucovorin (LV) rescue) as first-line chemotherapy in patients with locally advanced (inoperable) or metastatic gastric carcinoma. From July 1993 through August 1996, 36 patients with advanced gastric carcinoma received a regimen that consisted of: MTX 200 mg/m2 diluted in 250 ml normal saline by intravenous infusion over 20 minutes at hour 0; 5-FU 1,200 mg/m2 intravenous push injection at hour 20. Beginning 24 hours after MTX administration all patients received LV 15 mg/m2 intramuscularly every 6 hours for six doses. Cycles were repeated every 15 days. One patient was not assessable for response. Objective regression was observed in 15 of 37 patients (43%; 95% confidence interval, 26%-60%). One patient (3%) achieved complete response and 14 (40%) achieved partial response. No change was recorded in 14 patients (40%) and progressive disease was noted in six patients (17%). The median time to treatment failure was 7 months and the median survival was 12 months. Toxicity was within acceptable limits but one therapy-related death resulting from severe leukopenia occurred. The dose-limiting toxicity was mucositis. Five episodes of grade 3 or 4 stomatitis were observed and caused dosage modifications of MTX and 5-FU. Biochemical modulation of 5-FU by MTX appears as an attractive modality in patients with advanced gastric cancer. Further investigation both in experimental and clinical fields is needed to clearly define its role and to design the best modulatory strategy.

    Since March, 1981, 13 patients with locally advanced transitional cell carcinoma were treated by combined cisdiamminedichloroplatinum (cisplatin) and full dose radiotherapy. They were 10 men and 3 women. The patient ages ranged from 42 to 79 years, with a median of 59.5 years. The primary sites of transitional cell carcinoma were bladder in 5, ureter in 6, renal pelvis in 1 and prostate in 1. Radiotherapy consisted of a mean tumor dose of 48.7 gray, with a range of 40 to 66.4 gray, was administered with cobalt 60. Cisplatin was infused 5 days a week with a daily dose of 20 to 30 mg. 4 patients recieved 2 courses of cisplatin infusion and others 1 or less. Of the 4 evaluable patients 3 (75 %) achieved a complete response. Toxicity was evaluated for the 13 patients. Mainly gastrointestinal toxicity was noted: appetite loss in 9 (69.2 %), nausea and/or vomiting in 5 (38.5 %) and diarrhea in 5 (38.5 %). Leukocytopenia was noted in 7 patients (53.9 %), but in no one leukocyte count was less than 2000/mm 3 . Mild thrombocytopenia was noted only in 3 patients (23.1 %). All of these toxicities were mild, and the patients recovered soon after the therapy. Herein it is discussed about future problems such as solution of interaction mechanism, detection of practical dose and administering method of cisplatin and radiation. (author)

    Primary analysis from the pivotal ERIVANCE BCC study resulted in approval of vismodegib, a Hedgehog pathway inhibitor indicated for treatment of adults with metastatic or locally advanced basal cell carcinoma (BCC) that has recurred after surgery or for patients who are not candidates for surgery or radiation. An efficacy and safety analysis was conducted 12 months after primary analysis. This was a multinational, multicenter, nonrandomized, 2-cohort study in patients with measurable and histologically confirmed locally advanced or metastatic BCC taking oral vismodegib (150 mg/d). Primary outcome measure was objective response rate (complete and partial responses) assessed by independent review facility. After 12 months of additional follow-up, median duration of exposure to vismodegib was 12.9 months. Objective response rate increased from 30.3% to 33.3% in patients with metastatic disease, and from 42.9% to 47.6% in patients with the locally advanced form. Median duration of response in patients with locally advanced BCC increased from 7.6 to 9.5 months. No new safety signals emerged with extended treatment duration. Limitations include low prevalence of advanced BCC and challenges of designing a study with heterogenous manifestations. The 12-month update of the study confirms the efficacy and safety of vismodegib in management of advanced BCC. Copyright © 2015 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    We derive an expression for the accuracy with which sources can be localized using a network of gravitational wave detectors. The result is obtained via triangulation, using timing accuracies at each detector and is applicable to a network with any number of detectors. We use this result to investigate the ability of advanced gravitational wave detector networks to accurately localize signals from compact binary coalescences. We demonstrate that additional detectors can significantly improve localization results and illustrate our findings with networks comprised of the advanced LIGO, advanced Virgo and LCGT. In addition, we evaluate the benefits of relocating one of the advanced LIGO detectors to Australia.

    Purpose: Dose escalation using three-dimensional conformal radiotherapy (3D-CRT) is based on the hypothesis that increasing the dose can enhance tumor control. This study aimed to determine whether a dose-response relationship exists in local radiotherapy for primary hepatocellular carcinoma (HCC). Methods and Materials: One hundred fifty-eight patients were enrolled in the present study between January 1992 and March 2000. The exclusion criteria included the presence of an extrahepatic metastasis, liver cirrhosis of Child class C, tumors occupying more than two-thirds of the entire liver, and a performance status on the Eastern Cooperative Oncology Group scale of more than 3. Radiotherapy was given to the field, including the tumor, with generous margin using 6- or 10-MV X-rays. The mean radiation dose was 48.2 ± 7.9 Gy in daily 1.8-Gy fractions. The tumor response was assessed based on diagnostic radiologic examinations, including a computed tomography scan, magnetic resonance imaging, and hepatic artery angiography 4-8 weeks after the completion of treatment. Liver toxicity and gastrointestinal complications were evaluated. Results: An objective response was observed in 106 of 158 (67.1%) patients. Statistical analysis revealed that the total dose was the most significant factor associated with the tumor response. The response rates in patients treated with doses 50 Gy were 29.2%, 68.6%, and 77.1%, respectively. Survivals at 1 and 2 years after radiotherapy were 41.8% and 19.9%, respectively, with a median survival time of 10 months. The rate of liver toxicity according to the doses 50 Gy was 4.2%, 5.9%, and 8.4%, respectively, and the rate of gastrointestinal complications was 4.2%, 9.9%, and 13.2%, respectively. Conclusions: The present study showed the existence of a dose-response relationship in local radiotherapy for primary HCC. Only the radiation dose was a significant factor for predicting an objective response. The results of this study showed that 3D

    Purpose: To report the mature data of a prospective Phase II trial designed to evaluate the efficacy of an epidermal growth factor receptor inhibitor cetuximab (CTX) added to the concurrent therapy of weekly paclitaxel/carboplatin (PC) and daily radiation therapy (RT). Methods and Materials: From 2005 to 2009, a total of 43 patients were enrolled in the study. The median follow-up was 31 months (range, 9-59 months). All patients had Stage III/IV disease at presentation, and 67% had oropharyngeal primaries. The weekly IV dose schedules were CTX 250 mg/m{sup 2} (400 mg/m{sup 2} IV loading dose 1 week before RT), paclitaxel 40 mg/m{sup 2}, and carboplatin AUC 2. RT was given at 1.8 Gy per day to 70.2 Gy. Intensity-modulated RTwas used in 70% of cases. Results: All patients completed the planned RT dose, 74% without any treatment breaks. The planned CTX and PC cycles were completed in 70% (91% with at least seven of planned nine cycles) and 56% (93% with at least seven of planned eight cycles) of patients, respectively. Toxicity included Grade 3 mucositis (79%), rash (9%), leucopenia (19%), neutropenia (19%), and RT dermatitis (16%). The complete response (CR) rate at the completion of therapy was 84%. The estimated 3-year local regional control rate was 72%. Six patients with an initial CR subsequently experienced a local recurrence, 10 patients experienced distant progression. The median overall survival and disease-free survivals have not been reached. The 3-year actuarial overall survival and disease-free survival were 59% and 58%, respectively. Conclusions: The addition of CTX to weekly PC and daily RT was well tolerated and resulted in encouraging local control and survival rates.

    Cetuximab (CET) is a potent inhibitor of the epidermal growth factor receptor and has been shown to have activity in squamous cell carcinoma of the head and neck (SCCHN). We conducted a single-arm phase II trial of a combination therapy comprising cisplatin (CIS), CET and hyperfractionated accelerated radiotherapy (HART). Patients with UICC stage III or IVA/B, M0 SCCHN were enrolled and treated with an initial dose of CET (400 mg/m{sup 2}) and then with a weekly dosage of 250 mg/m{sup 2} during HART. HART was started with a prescribed dosage of 2.0 Gy per day for 3 weeks, followed by 1.4 Gy twice daily to a total dose of 70.6 Gy to the gross tumour volume. CIS (40 mg/m{sup 2}) was administered weekly (days 1, 8, 15, 22, 29 and 36). The primary objective of the phase II study was to determine the 2-year progression-free survival (PFS). Between November 2007 and November 2010, a total of 74 patients were enrolled in the study, of whom 65 were evaluable (83% were men). Median age was 56 years (range 37-69 years). An Oropharyngeal primary tumour was diagnosed in 49%, T4a,b in 65% and N2/3 in 96% of the patients. Of these patients, 85% were smokers or ex-smokers. Complete remission (CR) was observed in 23 patients (35%). The most common toxicity grade was ≥3, including mucositis (58%) and dysphagia (52%). The 2- and 5-year overall survival rates were 64 and 41%, the 2- and 5-year PFS rates were 45 and 32%, and the 2- and 5-year locoregional control rates were 47 and 33%, respectively. The combination of weekly CIS with HART plus CET is a feasible regimen for these unfavourable smoking-induced cancers. However, the parallel US study (RTOG 0522) showed no advantage of the enhanced triple therapy compared to chemoradiotherapy alone. (orig.)

If left untreated, BCCs can become locally aggressive or even metastasize. Currently available treatments include local destruction, surgery, and radiation. Systemic options for advanced disease are limited. The Hedgehog (Hh pathway is aberrantly activated in a majority of BCCs and in other cancers. Hh pathway inhibitors are targeted agents that inhibit the aberrant activation of the Hh pathway, with smoothened being a targeted component. Sonidegib is a novel smoothened inhibitor that was recently approved by the US Food and Drug Administration. This review focuses on BCC pathogenesis and the clinical efficacy of sonidegib for the treatment of advanced BCC. Keywords: nonmelanoma skin cancer, Hedgehog pathway, clinical trials

    Background: Urothelial carcinoma is the most common malignant tumor arising from the pelvocalyceal system. Helical computed tomography (CT) is probably the best preoperative-stage modality for the determination of treatment plan and prognosis. Purpose: To obtain helical CT imaging features suggesting advanced pelvocalyceal urothelial carcinoma. Material and Methods: Preoperative CT images in 44 patients with pelvocalyceal urothelial carcinoma were retrospectively reviewed and correlated with the pathological examination to determine imaging features suggesting stage III or IV of the disease. Results: Pathological stages revealed stage I in 16, stage II in three, stage III in 17, and stage IV in eight patients. Seven patients had metastatic lymph nodes. CT imaging showed that renal parenchymal invasion, sinus fat invasion, and lymph node metastasis were highly suggestive of advanced urothelial cell carcinoma (P<0.05). Helical CT sensitivity, specificity, and accuracy for advanced pelvocalyceal urothelial carcinoma were 76% (19/25), 84% (16/19), and 80% (35/44), respectively. Conclusion: Preoperative helical CT may suggest imaging features of advanced urothelial carcinoma, influencing treatment plan and patient prognosis, even though its accuracy is not so high

    Purpose: to evaluate the potential benefit of proton therapy and photon based intensity-modulated radiotherapy in comparison to 3-D conformal photon radiotherapy (3D-CRT) in locally advanced cervix cancer. Patients and methods: in five patients with advanced cervix cancer 3D-CRT (four-field box) was compared with intensity modulated photon (IMXT) and proton therapy (IMPT) as well as proton beam therapy (PT) based on passive scattering. Planning target volumes (PTVs) included primary tumor and pelvic and para-aortic lymph nodes. Dose-volume histograms (DVHs) were analyzed for the PTV and various organs at risk (OARs) (rectal wall, bladder, small bowel, colon, femoral heads, and kidneys). In addition dose conformity, dose inhomogeneity and overall volumes of 50% isodoses were assessed. Results: all plans were comparable concerning PTV parameters. Large differences between photon and proton techniques were seen in volumes of the 50% isodoses and conformity indices. DVH for colon and small bowel were significantly improved with PT and IMPT compared to IMXT, with D{sub mean} reductions of 50-80%. Doses to kidneys and femoral heads could also be substantially reduced with PT and IMPT. Sparing of rectum and bladder was superior with protons as well but less pronounced. Conclusion: proton beam RT has significant potential to improve treatment related side effects in the bowel compared to photon beam RT in patients with advanced cervix carcinoma. (orig.)

    Background and purpose: To evaluate long-term outcome in locoregionally advanced nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy. Material and methods: Between January 2006 and August 2008, 249 patients with stage III–IVb NPC were treated by IMRT plus concurrent chemotherapy in this multicenter prospective study. Results: With a mean follow-up of 54.1 months, the 5-year actuarial rates of overall survival (OS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant metastasis-free survival (DMFS) were 78.4%, 86.8%, 88.4%, 78.0%, respectively. There were 29 local recurrences, 25 regional recurrences and 52 distant metastases, respectively. Distant metastasis is the main cause of treatment failure. N-stage was an independent prognostic factor for LRFS, RRFS, DMFS and OS. Acute toxicity ⩾grade III mainly consisted of mucositis (34.9%), neutropenia (11.2%), xerostomia (5.6%), and dermatitis (5.2%). The main documented late toxicity was xerostomia, and the severity of xerostomia decreased over time. At 24 months after treatment, 13.2% of patients had grade 2 xerostomia, and none had grade 3 or 4 xerostomia. Conclusions: IMRT with concurrent cisplatin chemotherapy resulted in encouraging rates of local and distant control and overall survival with acceptable rates of acute and limited rates of late toxicity in patients with locoregionally advanced NPC. Distant metastasis remained the main cause of failure. More effective systemic therapy should be explored for patients with advanced N-stage

    To evaluate the efficacy and toxicity of vinorelbine (VNB) as single-agent neoadjuvant chemotherapy in advanced cervical carcinoma (ACC). Between December 1993 and October 1995, 43 untreated patients with stages IIB to IVA squamous cell cervical cancer were entered onto this study. Forty-two patients are assessable for response and 43 for toxicity. The median age was 46 years (range, 28 to 65). Distribution by stages (International Federation of Gynecology and Obstetrics [FIGO]) was as follows: IIB, 18 patients; IIIA, one; IIIB, 19; and IVA, five. Therapy consisted of VNB 30 mg/m2 by 20-minute intravenous (IV) infusion repeated weekly for 12 injections and followed by radical surgery if feasible or definitive radiotherapy. Both staging and response assessment were performed by a multidisciplinary team. One patient was considered not assessable for response. A total of 493 cycles of therapy were administered and objective remissions were observed in 19 of 42 patients (45%; 95% confidence interval, 30% to 60%). Two patients (5%) had a complete response (CR) and 17 (40%) a partial response (PR); no change (NC) was observed in 16 (38%) and progressive disease (PD) in seven (17%). Six of 19 patients (32%) who achieved objective responses (ORs) underwent surgery. The median time to failure and median survival time have not been reached yet. There were no therapy-related deaths. The dose-limiting toxicity was myelosuppression. Leukopenia occurred in 35 patients (81%) and was grade 3 or 4 in seven (17%). Twelve patients (28%) developed peripheral neuropathy, while myalgias occurred in 10 (23%). Constipation was observed in nine patients (21%), one with a prolonged ileum. Phlebitis was recorded in 18 patients (41%). In contrast, emesis and mucositis were rarely observed. No patient developed alopecia grade 3. By the end of the twelfth course of treatment, the average received dose-intensity was 85.4% of that projected. VNB is an active drug against ACC with moderate

    Objective: To explore the clinical staging of moderately advanced and advanced thoracic esophageal carcinoma by evaluating the prognosis and provide criteria for individual treatment. Methods: The authors retrospectively analyzed 500 patients with moderately advanced and advanced thoracic esophageal carcinoma treated by radiotherapy alone. According to the primary lesion length by barium meal X-ray film, the invasion range and the relation between location and the surrounding organs by CT scans the disease category was classified by a 6 stage method and a 4 stage method. With the primary lesion divide into T1, T2a, T2b, T3a, T3b and T4 incorporating the locregional lymph node metastasis, a 6 stage system was obtained, I, IIa , IIb, IIIa, IIIb and IV. The results of this as compared with those of 4 stage system, the following data were finally arrived at. Results: Among the 500 cases, there were T1 23, T2a 111, T2b 157, T3a 84, T3b 82 and T4 43. The survival rates of these six categories showed significant differences (χ 2 =63.32, P 2 =56.29, P 2 =94.29, P 2 =83.48, P<0.05). Conclusions: Both the 6 stage and 4 stage systems are adaptable to predict prognosis of moderately advanced and advanced esophageal carcinoma treated by radiotherapy alone. For simplicity and convenience, the 4 stage classification is recommended. (authors)

    Colorectal cancer is the second most frequent malignant tumor in the United States and fourth most frequent tumor in Korea. Surgery has been used as a primary treatment modality but reported overall survivals after curative resection were from 20% to 50%. Local recurrence is the most common failure in the treatment of locally advanced colorectal cancer. Once recurrence has developed, surgery has rarely the role and the five year survival of locally advanced rectal cancer is less than 5%, this indicated that significant improvement of local control could be achieved. We performed 6 cases of IORT for locally advanced colorectal cancer which is he first experience in Korea. Patient's eligibility, treatment applicator, electron energy, dose distribution on the surface and depth within the treatment field and detailed skills are discussed. We hope that our IORT protocol can reduce local failure and increase the long term survival significantly

    Objective: To retrospectively analyze the effectiveness of transarterial infusion chemotherapy of gemcitabine and 5-fluorouracil in advanced pancreatic carcinoma. Methods: Twenty-two patients with advanced pancreatic carcinoma were treated with transarterial infusion chemotherapy. Gemcitabine and 5-fluorouracil was administered to the patients via an interarterial catheter. Then the tumor response rate and clinical benefit were observed. Results: A clinical benefit was obtained in 8 patients (36.4%). The tumor response rate was 13.6%. Median survival for all the patients was 6.1 months. Median time to tumor progression was 2.9 months. Conclusion: Transarterial infusion chemotherapy with a combination of gemcitabine and 5-fluorouracil appears to have good clinical benefit and may prolong the survival time of patients with advanced pancreatic carcinoma

    Purpose: To assess the dosimetric and clinical results of three-dimensional conformal radiotherapy (3D CRT) for locally recurrent nasopharyngeal carcinoma (NPC). Methods: A total of 86 patients with locally recurrent NPC were retreated with 3D CRT. The median prescribed dose was 68 Gy with 2 Gy per fractionation. Dosimetric quality was evaluated with dose distribution in planning target volume (PTV) and specified organs at risk (OAR), dose conformity index (CI) and dose homogeneity index (HI). The actuarial rate of local failure-free (LFF), overall survival (OS) and major late toxicities (MLT) were estimated with Kaplan-Meier method. Multivariate analysis for prognosis was performed using the Cox regression proportional hazards model. Results: The mean dose to PTV averaged 66.8 Gy, and the dose to specified OAR was acceptable. The average value of CI and HI was 0.59 and 9.1%. The 5-year actuarial rate of LFF and OS was 71 and 40%, respectively. The 5-year actuarial incidence of MLT≥Grade 3 and ≥Grade 4 were 100 and 49%, respectively. The major prognostic factors were T stage and the size of gross tumor volume (GTV). Advanced T stage and large GTV volume were associated with poor LFF and OS and high risk of MLT. Conclusion: The dosimetric quality of 3D CRT for locally recurrent NPC is generally excellent. A relatively high local control was achieved with this technique. However, the incidence of late toxicities were not found to decrease as originally expected. Early diagnosis of the recurrence and reasonable definition of the target volume are crucial to achieve a better outcome

    Encouraging data for targeted therapy in head-and-neck squamous cell carcinoma are opening new options for treatment. Phase III trials of cetuximab, an antibody directed against the epidermal growth factor receptor (egfr) have demonstrated benefit in the locally advanced and metastatic settings. Recognizing the importance of emerging therapies, Cancer Care Ontario published guideline recommendations for egfr-targeted therapy in stage iii and iv head-and-neck cancer. The present paper takes a further look at the population for whom an offer of cetuximab therapy may be appropriate. PMID:20697514

    Background: in advanced vaginal recurrences of cervical and endometrial carcinomas therapeutic options are rare because of preceding therapy. Patients and methods: 23 patients developing advanced vaginal recurrences of cervical and endometrial carcinomas were included. 15 patients started with external-beam therapy to the pelvis and eight patients after preceding radiotherapy underwent brachytherapy alone. All patients had ultrasound-guided implantation of transvaginal or transperineal interstitial needles for brachytherapy. Median prescribed total dose was 64 Gy. Results: 18 patients (78%) achieved complete remission. Six patients are alive without tumor and one with tumor after a median follow-up of 64 months. 14 patients died of tumor and two of intercurrent disease. 5-year disease-specific survival and local control rate were 43% and 47%, respectively, in patients with complete remission. Univariate analysis found time to relapse > 2 years, initial diameter {<=} 4 cm, initial volume < 15 cm{sup 3}, no extension to the pelvic side wall, volume before brachytherapy < 7.5 cm{sup 3}, brachytherapy coverage index > 0.8, and prescribed total dose > 64 Gy being positive predictors for local control and survival. Conclusion: the use of ultrasound guidance for placement of interstitial needles in template-based brachytherapy of advanced recurrent gynecologic malignancies is a feasible, safe, and cheap method with encouraging results. Today, ultrasound imaging can be also used to some extent for treatment planning which requires further development. Patient- and treatment-related prognostic factors can be defined. (orig.)

    2002-01-01

    Purpose: To evaluate the role of adjuvant chemotherapy in locally advanced nasopharyngeal carcinoma (NPC) patients, we conducted a randomized Phase III trial comparing radiotherapy (RT) followed by adjuvant chemotherapy to RT alone in patients with advanced NPC. Methods and Materials: Between November 1994 and March 1999, 157 patients with Stage IV, M 0 (UICC/AJCC, 1992) advanced NPC disease were randomized to receive standard radiotherapy, as follows: 35-40 fractions, 1.8-2.0 Gy/fraction/day, 5 days/week, to a total dose 70-72 Gy with or without 9 weekly cycles of 24-h infusional chemotherapy (20 mg/m 2 cisplatin, 2,200 mg/m 2 5-fluorouracil, and 120 mg/m 2 leucovorin) after RT. Of 157 patients enrolled, 154 (77 radiotherapy, 77 combined therapy) were evaluable for survival and toxicity analysis. Results: With a median follow-up of 49.5 months, the 5-year overall survival and relapse-free survival rates were 60.5% vs. 54.5% (p = 0.5) and 49.5% vs. 54.4% (p = 0.38) for the radiotherapy-alone group and the combined radiotherapy and adjuvant chemotherapy group, respectively. The Cox regression showed that the hazard rates ratio of combined treatment to RT alone was 0.673 (p value = 0.232); the 95% confidence interval was 0.352 and 1.288, respectively. Patients who received combined treatment had a lower systemic relapse rate than radiotherapy-alone patients, according to relapse pattern analysis. The incidence of leukopenia (≥ Grade 3) occurred in 17 out of 819 (2.1%) cycles of weekly chemotherapy. No patient developed moderate to severe mucositis (≥ Grade 3). Conclusions: We conclude that adjuvant chemotherapy after RT for patients with advanced NPC has no benefit for overall survival or relapse-free survival

    The Hedgehog pathway inhibitor vismodegib has shown clinical benefit in patients with advanced basal cell carcinoma and is approved for treatment of patients with advanced basal cell carcinoma for whom surgery is inappropriate. STEVIE was designed to assess the safety of vismodegib in a situation similar to routine practice, with a long follow-up. In this multicentre, open-label trial, adult patients with histologically confirmed locally advanced basal cell carcinoma or metastatic basal cell carcinoma were recruited from regional referral centres or specialist clinics. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and adequate organ function. Patients with locally advanced basal cell carcinoma had to have been deemed ineligible for surgery. All patients received 150 mg oral vismodegib capsules once a day on a continuous basis in 28-day cycles. The primary objective was safety (incidence of adverse events until disease progression or unacceptable toxic effects), with assessments on day 1 of each treatment cycle (28 days) by principal investigator and coinvestigators at the site. Efficacy variables were assessed as secondary endpoints. The safety evaluable population included all patients who received at least one dose of study drug. Patients with histologically confirmed basal cell carcinoma who received at least one dose of study drug were included in the efficacy analysis. An interim analysis was pre-planned after 500 patients achieved 1 year of follow-up. This trial is registered with ClinicalTrials.gov, number NCT01367665. The study is still ongoing. Between June 30, 2011, and Nov 6, 2014, we enrolled 1227 patients. At clinical cutoff (Nov 6, 2013), 499 patients (468 with locally advanced basal cell carcinoma and 31 with metastatic basal cell carcinoma) had received study drug and had the potential to be followed up for 12 months or longer. Treatment was discontinued in 400 (80

    Purpose: Local recurrences of nasopharyngeal carcinoma (NPC) may be salvaged by reirradiation with conventional techniques, but with significant morbidity. Intensity-modulated radiation therapy (IMRT) may improve the therapeutic ratio by reducing doses to normal tissue. The aim of this study was to address the efficacy and toxicity profile of IMRT for a cohort of patients with locally recurrent NPC. Methods and Materials: Between August 2003 and June 2009, 70 patients with radiologic or pathologically proven locally recurrent NPC were treated with IMRT. The median time to recurrence was 30 months after the completion of conventional radiation to definitive dose. Fifty-seven percent of the tumors were classified asrT3–4. The minimum planned doses were 59.4 to 60 Gy in 1.8- to 2-Gy fractions per day to the gross disease with margins, with or without chemotherapy. Results: The median dose to the recurrent tumor was 70 Gy (range, 50–77.4 Gy). Sixty-five patients received the planned radiation therapy; 5 patients received between 50 and 60 Gy because of acute side effects. With a median follow-up time of 25 months, the rates of 2-year locoregional recurrence-free survival, disease-free survival, and overall survival were 65.8%, 65.8%, and 67.4%, respectively. Moderate to severe late toxicities were noted in 25 patients (35.7%). Eleven patients (15.7%) had posterior nasal space ulceration, 17 (24.3%) experienced cranial nerve palsies, 12 (17.1%) had trismus, and 12 (17.1%) experienced deafness. Extended disease-free interval (relative risk 2.049) and advanced T classification (relative risk 3.895) at presentation were adverse prognostic factors. Conclusion: Reirradiation with IMRT provides reasonable long-term control in patients with locally recurrent NPC.

    Knowing esophageal tumors behavior in relationship to lymph node involvement, distant metastases and local tumor invasion is of paramount importance for the best esophageal tumors management. To describe lymph node involvement, distant metastases, and local tumor invasion in esophageal carcinoma, according to tumor topography and histology. A total of 444 patients with esophageal squamous cell carcinoma and 105 adenocarcinoma were retrospectively analyzed. They were divided into four groups: adenocarcinoma and squamous cell carcinoma in the three esophageal segments: cervical, middle, and distal. They were compared based on their CT scans at the time of the diagnosis. Nodal metastasis showed great relationship with of primary tumor site. Lymph nodes of hepatogastric, perigastric and peripancreatic ligaments were mainly affected in distal tumors. Periaortic, interaortocaval and portocaval nodes were more commonly found in distal squamous carcinoma; subcarinal, paratracheal and subaortic nodes in middle; neck chains were more affected in cervical squamous carcinoma. Adenocarcinoma had a higher frequency of peritoneal involvement (11.8%) and liver (24.5%) than squamous cell carcinoma. Considering the local tumor invasion, the more cranial neoplasia, more common squamous invasion of airways, reaching 64.7% in the incidence of cervical tumors. Middle esophageal tumors invade more often aorta (27.6%) and distal esophageal tumors, the pericardium and the right atrium (10.4%). Esophageal adenocarcinoma and squamous cell carcinoma in different topographies present peculiarities in lymph node involvement, distant metastasis and local tumor invasion. These differences must be taken into account in esophageal cancer patients' care.

    Purpose: To report preliminary results of a very accelerated radiation therapy Phase I/II trial in locally advanced head and squamous cell carcinomas (HNSCC). Methods and Materials: Between 01/92 and 06/93, 35 patients with an unresectable HNSCC were entered in this study. Thirty-two (91%) had Stage IV, and 3 had Stage III disease. The mean nodal diameter, in patients with clinically involved nodes (83%), was 6.3 cm. The median Karnovsky performance status was 70. The treatment consisted of a twice daily schedule (BID) giving 62 Gy in 20 days. Results: In all cases, confluent mucositis was observed, which started about day 15 and resolved within 6 to 10 weeks. Eighty percent of patients had enteral nutritional support. The nasogastric tube or gastrostomy was maintained in these patients for a mean duration of 51.8 days. Eighteen patients (53%) were hospitalized during the course of treatment due to a poor medical status or because they lived far from the center (mean 25 days). Nineteen patients (56%) (some of whom were initially in-patients) were hospitalized posttreatment for toxicity (mean 13 days). Five patients (15%) were never hospitalized. During the follow-up period, 12 local and/or regional failures were observed. The actuarial 18-month loco-regional control rate was 59% (95% confidence interval, 45-73%). Conclusions: The dramatic shortening of radiation therapy compared to conventional schedules in our series of very advanced HNSCC resulted in: (a) severe acute mucosal toxicity, which was manageable but required intensive nutritional support in all cases; and (b) high loco-regional response rates, strongly suggesting that the time factor is likely to be critical for tumor control in this type of cancer.

    The accumulation of immunosuppressive cells and exhausted effector T cells highlight an important immune dysfunction in advanced stage hepatocellular carcinoma (HCC) patients. These cells significantly hamper the efficacy immunotherapies and facilitate HCC progression. We have recently demonstrated that the multipronged depletion of immunosuppressive cells potentially restores effector T-cell function in HCC.

    Full Text Available Hedgehog (Hh signaling pathway is present in many animals and plays an important role in regulating embryonic development and differentiation. Aberrant activation of Hh signaling contributes to the pathogenesis of many malignancies. Recent studies have shown that dysregulated Hh signaling pathway participates in the tumorigenesis, tumor invasion, and metastasis of hepatocellular carcinoma (HCC. Investigation of the relationship between Hh signaling pathway and HCC will help elucidate the molecular mechanism of pathogenesis of HCC and provide a new insight into the development of novel anticancer therapy and therapeutic target.

    The outcomes of locoregionally advanced nasopharyngeal carcinoma patients treated with concurrent chemoradiation (CCRT) using intensity-modulated radiotherapy (IMRT) with/without neoadjuvant chemotherapy (NCT) were evaluated. Eighty-three patients who underwent NCT followed by CCRT (49%) or CCRT with/without adjuvant chemotherapy (51%) were reviewed. To the gross tumor, 67.5 Gy was prescribed. Weekly cisplatin was used as concurrent chemotherapy. With a median follow-up of 49.4 months, the 5-year local control, regional control, distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival rates were 94.7%, 89.3%, 77.8%, 68.0%, and 81.8%, respectively. In multivariate analysis, the American Joint Committee on Cancer stage (p = 0.016) and N stage (p = 0.001) were negative factors for DMFS and DFS, respectively. Overall, NCT demonstrated no benefit and an increased risk of severe hematologic toxicity. However, compared to patients treated with CCRT alone, NCT showed potential of improving DMFS in stage IV patients. CCRT using IMRT resulted in excellent local control and survival outcome. Without evidence of survival benefit from phase III randomized trials, NCT should be carefully administered in locoregionally advanced nasopharyngeal carcinoma patients who are at high-risk of developing distant metastasis and radiotherapy-related mucositis. The results of ongoing trials are awaited.

    Full Text Available The advances in localization based technologies and the increasing importance of ubiquitous computing and context-dependent information have led to a growing business interest in location-based applications and services. Today, most application requirements are locating or real-time tracking of physical belongings inside buildings accurately; thus, the demand for indoor localization services has become a key prerequisite in some markets. Moreover, indoor localization technologies address the inadequacy of global positioning system inside a closed environment, like buildings. Based on this, though, this paper aims to provide the reader with a review of the recent advances in wireless indoor localization techniques and system to deliver a better understanding of state-of-the-art technologies and motivate new research efforts in this promising field. For this purpose, existing wireless localization position system and location estimation schemes are reviewed, as we also compare the related techniques and systems along with a conclusion and future trends.

    Nearly half of breast cancer patients in developing countries present with a locally advanced cancer. Treatment is centered on a multimodal approach based on chemotherapy, surgery and radiotherapy. The growing use of neoadjuvant chemotherapy has led to a more conservative surgical approach; nonetheless, it is not yet considered as a standard. There are no clear recommendations on the use of a radiotherapy boost in such situation. A Medline search was developed. Most articles are retrospective series. Survival free of locoregional relapse in patients treated with neoadjuvant chemotherapy, breast conserving surgery and radiotherapy is good. All articles described a boost administered to nearly all patients without regard to their prognostic factors, given that a locally advanced tumor is already considered as a poor prognostic factor. Even tough the poor level of evidence, a recommendation can be made: radiotherapy boost should be administered to all patients with locally advanced breast cancer treated with neoadjuvant chemotherapy and breast conserving surgery.

    The molecular pathogenesis and classification of colorectal carcinoma are based on the traditional adenomaecarcinoma sequence, serrated polyp pathway, and microsatellite instability (MSI). The genetic basis for hereditary nonpolyposis colorectal cancer is the detection of mutations in the MLH1, MSH2, MSH6, PMS2, and EPCAM genes. Genetic testing for Lynch syndrome includes MSI testing, methylator phenotype testing, BRAF mutation testing, and molecular testing for germline mutations in MMR genes. Molecular makers with predictive and prognostic implications include quantitative multigene reverse transcriptase polymerase chain reaction assay and KRAS and BRAF mutation analysis. Mismatch repair-deficient tumors have higher rates of programmed death-ligand 1 expression. Cell-free DNA analysis in fluids are proving beneficial for diagnosis and prognosis in these disease states towards effective patient management. Copyright © 2018 Elsevier Inc. All rights reserved.

    Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist to delay further pubertal progression. In patients with functioning ACC and surgical removal, clinical follow-up and hormonal marker examination for the secondary effects of excessive hormone secretion may be a useful option at least every 2 or 3 months after surgery.

    Merkel cell carcinoma (MCC) is a rare but aggressive form of skin cancer that occurs in the elderly, is associated with UV radiation and immunosuppression. Initial treatment consists of wide excision with adjuvant radiation. Although the tumor is sensitive to chemotherapy, long-term survival is unusual and there had been no US FDA-approved drugs prior to 2017. The recognition that MCC is associated with the Merkel cell polyomavirus occurs more commonly in immune-compromised patients and tumors express PD-L1 suggested testing immunotherapy. A study of an anti-PD-L1 antibody, avelumab, in chemotherapy-refractory MCC demonstrated a response rate of 31.8% resulting in FDA approval in March 2017 and EMA in September 2017. This review will discuss the disease, role of avelumab and other emerging treatment strategies for MCC.

    Full Text Available Abstract Background Chemo-radiotherapy offers an alternative to primary surgery and adjuvant therapy for the management of locally advanced stage IV squamous cell carcinomas of the tonsil. Methods A retrospective analysis was performed of the outcomes of 41 patients with locoregionally advanced squamous cell carcinoma of the tonsil treated non-surgically at the Yorkshire Cancer Centre between January 2004 and December 2005. Due to long radiotherapy waiting times, patients received induction chemotherapy with cisplatin and 5-fluorouracil followed by either cisplatin concurrent chemoradiotherapy or radiotherapy alone. Results Median age was 55 years (range 34-76 years and 28 (68% patients were male. 35/41 patients (85% received 2 or more cycles of induction chemotherapy. Following induction chemotherapy, 32/41 patients (78% had a clinical response. Concomitant chemotherapy was given to 30/41 (73%. All patients received the planned radiotherapy dose with no delays. There were no treatment related deaths. Six (15% patients had gastrostomy tubes placed before treatment, and 22 (54% required nasogastric tube placement during or after treatment for nutritional support. 17 patients required unplanned admissions during treatment for supportive care. At 4 months post treatment assessment 35 out of 41 (85% patients achieved complete clinical and radiographic response. Median follow-up is 38 months (8-61 months. Local and regional control rate in complete responders at 3 years was 91%. Distant metastases have been found in 4 (9.8% patients. Three year progression-free survival rate in all patients is 75%. The 3-year cause specific survival and overall survival are 75% and 66% respectively. Conclusion Cisplatin-based induction and concurrent chemoradiotherapy provides excellent tumour control with acceptable toxicity for patients with locally advanced tonsillar cancer.

    Discussions are made on local control of 31 cases of esophageal carcinoma which were treated by external and intracavitary irradiation between May 1980 and March 1983. X-ray and endoscopic findings have been used for the image diagnosis. Before the begining of radiotherapy, types of esophageal carcinoma were determined from X-ray findings according to Borrmann's classification. There were 10 cases of types 1 and 2, and 21 cases of types 3 and 4. After completion of external and intracvitary irradiation, all 10 cases of types 1 and 2 were locally controlled. Of the 21 cases of types 3 and 4, 8 cases which developed stenosis or deep ulcer after external irradiation all failed in local control. The remaining 13 cases of types 3 and 4 were locally controlled except 2 by radiotherapy. (author)

    Intraoperative radiotherapy (IORT) was performed on 20 patients with colorectal cancer. IORT with a single dose of 20 to 40 Gy was delivered to the residual tumor, tumor bed, and/or lymphnode regions. Although most of the patients had advanced lesions, local control was achieved in 67 % of the patients when IORT was combined with tumor resection, and 4 patients survived more than 5 years. There were no serious complications, except for contracture or atrophy of the psoas muscle seen in 2 patients. IORT combined with external beam radiotherapy should be a useful adjuvant therapy to surgery for locally advanced colorectal cancer. (author)

    A case of Fournier's gangrene in a 69-year-old man was reported. He had diabetes mellitus and had received 30 Gy radiation for local recurrence of rectal carcinoma. Immediately after the irradiation the disease of scrotum began as redness and swelling, and developed ulcer and necrosis. Antibiotics and local drainage were not of benefit, so we performed debridement and obtained good result. We described our experience of the gangrene from the early phase to recovery. (author)

    Cisplatin-based combinations are considered to be the standard treatment for advanced transitional cell carcinoma (TCC) of the urothelium. Many of the patients are elderly with concomitant diseases or impaired renal function. We studied the tolerance and activity of the gemcitabine/carboplatin combination as a therapeutic alternative. Patients with locally advanced or metastatic TCC of the urothelium were treated with gemcitabine 1000 mg/m(2) on Days 1 and 8 and carboplatin area under the concentration-time curve 5 on Day 1 every 21 days. Patients with creatinine clearance of 30 mL/min or above and Karnofsky performance status (KPS) scores 60 or above were enrolled. A total of 227 cycles were administered to 41 patients, with an average of 5.5 cycles per patient (range, 1-8 cycles). Creatinine clearance was below 60 mL/min in 54% of patients, KPS was 70 or below in 37% of patients, and 37% of patients were 70 years old or older. Hematologic toxicity was mainly Grade 3/4 neutropenia in 63%, Grade 3/4 thrombocytopenia in 32%, and Grade 3/4 anemia in 54% of patients. There were only three episodes of febrile neutropenia and one death from neutropenic sepsis. Nonhematologic toxicity was mild, with asthenia as the most frequently reported event. We obtained 6 complete and 17 partial responses, for an overall response rate of 56.1% (95% confidence interval [CI], 40.6-71.6%). Progression-free survival was 7.2 months (95% CI, 5.7-8.5) and median survival was 10.1 months (95% CI, 8.8-12.2). The combination of gemcitabine plus carboplatin achieves a similar result to doublets using cisplatin. It has an acceptable toxicity profile and enables patients with impaired renal function and/or poor performance status and elderly patients to be treated.

    Background and purpose: The aim of this retrospective study was to analyze the outcome of patients with locally advanced cervical carcinoma treated by adjuvant radiochemotherapy and to determine risk factors for local and distant relapse. Furthermore, acute and late effects of treatment were recorded. Patients and methods: A total of 72 patients with FIGO stages I-III cervical carcinoma were treated by radical hysterectomy, pelvic lymphadenectomy, and postoperative radiochemotherapy. Only patients with positive pelvic lymph nodes, parametrial involvement, positive margins, or tumor bulk were eligible. Patients were irradiated with a standard pelvic field (50.4 Gy in 28 fractions). The majority of patients received platinum-based chemotherapy. Results: After a median follow-up of 37 months, estimated 1-, 2-, and 4-year disease-free survival (DFS) and overall survival (OS) rates were 89%, 80%, 68% and 95%, 88%, 76%, respectively. Nine of the 72 patients had pelvic recurrences including only 1 isolated local failure; 23 of the 72 patients presented with distant relapse. The majority of relapses occurred within the first 3 years after adjuvant treatment. The number of positive pelvic lymph nodes (> 1) was the strongest prognostic factor for DFS. Treatment was well tolerated with transient acute hematologic ({proportional_to}30%) and gastrointestinal ({proportional_to}30%) grade 3 toxicity. Small bowel obstruction ({proportional_to}6%) was the only important late sequelae. Conclusion: Adjuvant radiochemotherapy in patients with advanced cervical cancer and several risk factors is highly effective to prevent local relapse. Future efforts to improve outcome should be placed on improvement of systemic control especially in subgroups with high-risk features for distant relapse. Combined treatment was well tolerated with moderate acute and late toxicity. (orig.)

    During the period 1982-1988, 34 patients with advanced oral or oropharyngeal carcinoma were treated with radical radiation therapy combined with intraarterial chemotherapy. Five patients were clinically staged as Stage II,15 as Stage III, and 14 as Stage IV. For intraarterial chemotherapy, ACNU (25mg/body) or CDDP (20 mg/m 2 ) plus MMC (6 mg/m 2 ) was used. Overall, the complete response rate was 56%: it was independent of the site of carcinoma, clinical stage, and the kind of drugs. The two-year cumulative survival rate was 80% for Stage II, 56% for Stage III, and 61% for Stage IV. Side effects were not so severe as to continue with the withdrawal of chemotherapy. In view of the efficacy and safety, combined radiation therapy and intraarterial chemotherapy should be performed in the treatment of oral or oropharyngeal carcinoma. (N.K.)

    Purpose : Despite a development for therapeutic machines and advance in modern radiation therapy techniques, locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate. Combination of chemotherapy and radiotherapy demonstrated benefit in improving local control and possibly the overall survival. Our study was performed to evaluate effect of concurrent chemoradiation on locally advanced uterine cervical cancer. Methods and Materials : Twenty six patients with locally advanced stage(FIGO stage IIB with ≥ 5 cm in diameter, III, IVA) were treated with combination of radiation therapy and concurrent cisplatinum between May of 1988 and September of 1993 at our hospital. Radiation therapy consisted of external irradiation and 1-2 sessions of intracavitary irradiation, Cisplatinum was administered in bolus injection of 25mg/m 2 at weekly intervals during the course of external radiation therapy. Results : Of the 26 patients, twenty-five patients were evaluable for estimation of response. Median follow-up period was 25 months with ranges from 3 to 73 months. Stage IIB, III, and IVA were 16, 5,4 patients, respectively. Twenty patients were squamous cell carcinoma. Response was noted in all 25 patients: complete response(CR) in 17/25(68%), partial response(PR) in 8/25(32%). Of the 24 patients except one who died of sepsis at 3 months follow-up, seventeen patients(70.8%) maintained local control in the pelvis: 16/17(94.1%) in CR, 1/17(14.3%) in PR. Fourteen of the 17 patients with CR are alive disease free on the completion of follow-up. Median survival is 28 months for CR and 15 months for PR. Analysis of 5-year survival by stage shows 11/16(59.8) in IIB, 3/5(60.6%) in III, and 1/4(25.0%) in IVA. Overall 5-year survival rate was 55.2%. Ten Patients recurred: 4 at locoregional, 3 in distant metastasis and 3 with locoregional and distant site. Toxicity by addition of cisplatinum was not excessive. Conclusion : Although the result of this

    The main stay of treatment for head and neck cancer patients with advanced disease has been chemotherapy with Cisplatin/5-FU and simultaneous applied radiotherapy. With this multimodality treatment including radical surgery after two cycles of neoadjuvant chemotherapy and 40 Gy radiotherapy we reported 60% complete remission after 5 years for patients with stage III/IV of head and neck cancer. Paclitaxel, a new plant product, has demonstrated significant antineoplastic activity in head and neck tumors (ECOG-Study: 40% RR). Therefore we performed a trial with Taxol/5-FU and simultaneous radiation in a neoadjuvant and postoperative adjuvant setting of stage III/IV squamous cell carcinoma of the head and neck with pre-existent contraindication against Cisplatin. Patients and Methods: 30 patients with a primarily inoperable stage III/IV of SCC of the head and neck were enrolled to receive day 1 and 29 Taxol 175 mg/m 2 as a 3-hour-infusion, followed by 120-hour-cvi of 1000 mg/m 2 /d 5-FU. Locally irradiation was given ad 40 Gy (2 Gy/d/day 1-26). Radical surgery followed about day 56. Postoperatively patients received again 2 cycles of Taxol/5-FU and simultaneous irradiation with 30 Gy. Results: So far 30 patients were treated and all patients reached a CR after complete treatment, ongoing for 23/30 patients for 6 till 34 months: 4 patients developed a second neoplasia, and 3 patients gloved a local relapse. The principal toxicity was moderate (neutropenia, peripheral neuropathy, arthralgia/myalgia) and sensible with supportive care (e.g. PEG). Conclusions: The results suggest that the treatment of SCC of the head and neck with Taxol/5-FU and simultaneous radiation and radical surgery is a highly effective schedule and comparable with the treatment with Cisplatin/5-FU.

    Uroplakins are differentiation-related membrane proteins of urothelium. We compared uroplakin expression and ultrastructural localization in human normal urothelium, papilloma and papillary carcinoma. Because of high recurrence rate of these tumours, treated by transurethral resection, we investigated urothelial tumour, resection border and uninvolved urothelium. Urinary bladder samples were obtained from tumour free control subjects and patients with papilloma and papillary carcinoma. Immunohistochemical and immunoelectron labelling of uroplakins were performed. In normal human urothelium with continuous uroplakin-positive superficial cell layer uroplakins were localized to flattened mature fusiform vesicles and apical plasma membrane of umbrella cells. Diverse uroplakin expression was found in papilloma and papillary carcinoma. Three aberrant differentiation stages of urothelial cells, not found in normal urothelium, were recognized in tumours. Diverse uroplakin expression and aberrant differentiation were occasionally found in resection border and in uninvolved urothelium. We demonstrated here that uroplakin expression and localization in urothelial tumours is altered when compared to normal urothelium. In patients with papilloma and papillary carcinoma immunolabelling of uroplakins at ultrastructural level shows aberrant urothelial differentiation. It is possible that aberrant differentiation stages of urothelial cells in resection border and in uninvolved urothelium contribute to high recurrence rate

    Full Text Available N-stage is related to distant metastasis in nasopharyngeal carcinoma (NPC patients. The purpose of this study was to evaluate the efficacy and toxicity of different nedaplatin-based chemotherapy regimens in advanced N2-3 stage NPC patients treated with intensity modulated radiation therapy (IMRT.Between April 2005 and December 2009, a total of 128 patients with N2-3 advanced NPC were retrospectively analyzed. Patients were treated with IMRT concurrent with 2 cycles of chemotherapy consisting of either nedaplatin plus paclitaxel (NP group, n = 67 or nedaplatin plus fluorouracil and paclitaxel (NFP group, n = 61. Two to four cycles of adjuvant chemotherapy were then administered every 21 days following concurrent chemoradiotherapy.With a median follow-up of 60 months, the 5-year overall survival (OS, progression-free survival (PFS, local-regional recurrence-free survival (LRRFS, and distant metastasis-free survival (DMFS for all patients were 81.4%, 71.5%, 87.8% and 82.0%, respectively. No significant difference in PFS (66.6% vs. 76.7%, P = 0.212 and LRRFS rates (89.0% vs. 86.3%, P = 0.664 was observed between the NP and NFP groups. The 5-year OS (75.4% vs. 88.5%, P = 0.046 and DMFS (75.1% vs. 89.0%, P = 0.042 rate were superior in the NFP group compared with the NP group. The NFP group had a higher incidence of grade 3-4 acute toxicities including bone marrow suppression (leukopenia: χ2 = 3.935, P = 0.047; anemia: χ2 = 9.760, P = 0.002; thrombocytopenia: χ2 = 8.821, P = 0.003, and both liver and renal dysfunction (χ2 = 5.206, P = 0.023 compared with the NP group. Late toxicities were moderate and no difference was observed between the two groups.IMRT concurrent with nedaplatin-based chemotherapy is an advocated regimen for patients with advanced N2-3 stage NPC. Patients with advanced N2-3 stage may be better candidates for the NFP regimen although this regimen was associated with a high acute toxicity rate.

    Although a randomized controlled trial for locally advanced pancreatic cancer (PC) has demonstrated a survival advantage for treatment with gemcitabine alone, chemoradiotherapy remains the treatment of choice for locally advanced disease in Japan. The aim of this study was to compare the survival benefits associated with gemcitabine and concurrent chemoradiotherapy in locally advanced unresectable PC. Seventy-seven patients with locally advanced unresectable PC were retrospectively enrolled from April 2001 to December 2006. All cases were histologically proven, and patients received gemcitabine chemotherapy (n=30) or concurrent chemoradiotherapy (based on 5-fluorouracil, n=28, or gemcitabine, n=19, as a radiosensitizer) at Aichi Cancer Center Hospital. Patients who received chemoradiotherapy had significantly better performance status than those who had chemotherapy. Tumor response was 0% for chemotherapy and 13% chemoradiotherapy, but survival benefit was similar among patients in the chemotherapy group (overall response (OS) 12 months; progression-free survival (PFS), 3 months) and those in the chemoradiotherapy group (OS, 13 months; PFS, 5 months). Two-year survival was 21% for chemotherapy patients and 19% for chemoradiotherapy patients. Severe toxicities (Grade 3-4 National Cancer Institute-Common Toxicity Criteria, version 3.0) were significantly more frequent for chemoradiotherapy than for chemotherapy. Gemcitabine chemotherapy showed similar survival benefit compared to 5-fluorouracil- and gemcitabine-based chemoradiotherapy. (author)

  13. Renal cell carcinoma: evolving approaches to advanced non-clear cell carcinoma

    Directory of Open Access Journals (Sweden)

    Daniel Y.C. Heng

    2011-12-01

    Full Text Available The treatment of metastatic renal cell carcinoma (RCC has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Many retrospective studies on the use of all three of these targeted therapies in patients with non-clear cell histology have demonstrated response rates ranging from 3.7%–16%. Although response rates may not be as high compared to patients with clear cell histologies, targeted therapy does provide a clinically meaningful response.

    We hypothesized that radiotherapy (RT) would improve both local and regional control with Merkel cell carcinoma of the head and neck. A single-institution institutional review board-approved study was performed including 113 patients with nonmetastatic Merkel cell carcinoma of the head and neck. Postoperative RT was delivered to the primary tumor bed (71.7% cases) ± draining lymphatics (33.3% RT cases). Postoperative local RT was associated with improved local control (3-year actuarial local control 89.4% vs 68.1%; p = .005; Cox hazard ratio [HR] 0.18; 95% confidence interval [CI] = 0.06-0.55; p = .002). Similarly, regional RT was associated with improved regional control (3-year actuarial regional control 95.0% vs 66.7%; p = .008; Cox HR = 0.09; 95% CI = 0.01-0.69; p = .02). Regional RT played an important role for both clinical node-negative patients (3-year regional control 100% vs 44.7%; p = .03) and clinical/pathological node-positive patients (3-year regional control 90.9% vs 55.6%; p = .047). Local RT was beneficial for all patients with Merkel cell carcinoma of the head and neck, whereas regional RT was beneficial for clinical node-negative and clinical/pathological node-positive patients. © 2016 Wiley Periodicals, Inc.

    2001-01-01

    Purpose: Whereas there are many reports regarding treatment of early vocal cord cancer with cobalt 60 or 2-4-MV X-rays, there are still few reports on the results of treatment with 6-MV X-rays. Theoretically, 6-MV X-rays result in greater underdosage of tumor at the air-tissue interface and at the anterior commissure. This paper analyzes the results of irradiation of early and moderately advanced squamous cell carcinoma of the true vocal cord treated exclusively with 6-MV X-rays in a community hospital. The literature pertinent to the issue is reviewed. Methods and Materials: Eighty-three patients with Tis, T1, T2, or T3 squamous cell carcinoma of the true vocal cord were treated with curative intent at Bethesda Memorial Hospital in Boynton Beach, Florida between April 1986 and April 1998. The dose schedules most commonly used were 63 Gy in 28 fractions (2.25 Gy per fraction once a day) for T1 tumors or 74.40 Gy in 62 fractions (1.2 Gy per fraction twice a day) for T2 and T3 tumors. All patients have minimum 2-year follow-up; 63 (76%) have 5-year minimum follow-up. Results: Local control was achieved in 6 of 6 Tis, 53 of 54 (98%) T1, 8 of 8 T2, and 6 of 6 T3 lesions. No complications were encountered. Conclusions: A recent literature review indicates that the treatment of early vocal cord cancer with 6-MV X-rays remains controversial. The dose schedules used in the present paper produced a high rate of local control, a finding that is consistent with reports of other investigators who used dose schedules similar to those used in the present series. However, several other investigators have reported significantly lower rates of local control for T1 or T2 glottic cancer treated with 6-MV X-rays when compared to results obtained with cobalt 60 or 4 MV at their own institution. The latter institutions used lower total doses and/or lower dose per fraction than those institutions reporting high rates of local control with 6 MV. Data from the literature, as well as our

    Coincident observations with gravitational wave (GW) detectors and other astronomical instruments are among the main objectives of the experiments with the network of LIGO, Virgo, and GEO detectors. They will become a necessary part of the future GW astronomy as the next generation of advanced detectors comes online. The success of such joint observations directly depends on the source localization capabilities of the GW detectors. In this paper we present studies of the sky localization of transient GW sources with the future advanced detector networks and describe their fundamental properties. By reconstructing sky coordinates of ad hoc signals injected into simulated detector noise, we study the accuracy of the source localization and its dependence on the strength of injected signals, waveforms, and network configurations.

    Objective: To summarize the author's experience which was obtained in observing and nursing the adverse reactions of advanced hepatocellular carcinoma patients who were treated with Sorafenib. Methods: The adverse reactions and their severity observed in 34 patients with advanced hepatocellular carcinoma who were treated with Sorafenib were retrospectively analyzed. Results: Side effects or toxic reaction were observed in all the patients, which included neutropenia, foot-hand syndrome (FHS), fatigue, diarrhea, hypertention, rash, etc. Five patients had to cut down the dose of Sorafenib in order to relieve the symptom, among them one patient had grade 4 FHS, 3 patients had grade 3 FHS and one patient had grade 3 neutropenia. Conclusion: Being familiar with sorafenib's adverse reaction, closely observing the patients condition and affording appropriate nursing measures, all the above items can definitely improve the therapeutic results and patient's living quality.

    Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma

    Non-metastatic metabolic related skeletal changes are predicted in patients with locally advanced bladder cancer. Renal impairment may be a contributing factor in such abnormalities. The aim of this study was to verify the presence of metabolic bone disease in patients with different pathological subgroups of locally advanced bladder cancer and determine its clinical impact, and to correlate these metabolic super scan features with variable laboratory tests of bone bio markers and renal functions. In this study, a total of 350 patients (mean age = 58±8.4 y) with histopathologically proven locally advanced bladder cancer; 238 transitional cell carcinoma (TCC), 100 squamous cell carcinoma (SCC), 7 adenocarcinoma, 2 mucinous adenocarcinoma, 2 undifferentiated carcinoma and 1 leiomyosarcoma. The patients were referred to the Nuclear Medicine Unit, National Cancer Institute, Cairo, Egypt, between July 2006 and December 2009. Whole body bone scan was obtained 3 hours following IV administration of 555-925 MBq Tc-99m MDP. Serum alkaline phosphatase (ALP), calcium and parathormone (PTH) levels were monitored as markers for bone metabolism while serum creatinine was used to monitor kidney function. The exclusion criteria included patients who had liver disease or those taking calcium or vitamin D supplement or any medication that affects bone metabolism. All bone scan results in the study were verified by correlation with other radiological imaging, laboratory data and follow-up for at least 12 months. According to bone scan results, patients were classified into four groups: group A: normal scan (n=223), group B: metabolic super scan features (MSS) (n=70), group C: metastatic bone disease (n=45) and group D: bone scan with indeterminate lesions (n=12). Osteomalacic MSS features were detected in 20 % of the studied patients (locally advanced bladder cancer) compared to 14.5% who had bone metastases. Contrary to metastases which showed high prevalence in TCC (P<0.001), MSS

    We report clinico-pathological studies on the effect of preoperative hyperthermia and chemotherapy combined with radiotherapy (HCR) for progress of the local curability of advanced esophageal carcinoma. The subjects of these studies were 17 patients who underwent subtotal esophagectomy after preoperative irradiation of 40 Gy from 1980 to 1989, of which 8 patients had HCR, 6 patients irradiation only (R), 3 patients both irradiation and chemotherapy (CR). The clinical response rate of the patients with R or CR was 33% (PR 3, MR 3, NC 3), and the histological effective (Ef{sub 3} or Ef{sub 2}) rate was 56% (Ef{sub 3} 1, Ef{sub 2} 4, Ef{sub 1} 4). The clinical response rate of the patients with HCR was 88% (PR 7, MR 1), and the histological effective rate was 100% (Ef{sub 3} 1, Ef{sub 2} 7). HCR was more effective than R or CR for the local lesion of esophageal carcinoma histopathologically (p<0.05). However, the survival rate of patients with HCR was similar to R and CR, respectively. These results suggest that further improvement of the heating methods and the methods of combining hyperthermia with irradiation and chemotherapy is needed. (author).

    The outcome of 42 patients who developed locally recurrent rectal carcinoma after initial local excision or electrocoagulation was presented. Five patients received combined surgery and radiotherapy (XRT). The remaining 37 patients were managed by XRT alone. The overall 5 years actuarial survival and local control rates were 21 and 22 percent, respectively. For patients who received XRT alone, the 5 year actuarial survival and local control rates were 20 and 15 percent, resp. The corresponding figures were 35 and 40 percent for patients who received a total XRT dose of 50 Gy or more. One patient who underwent combined treatment developed rectal and bladder incontinence requiring surgery. For patients with rectal recurrence after initial conservative surgery, XRT is an alternative to abdominoperipheral resection if major resection is contraindicated. (author). 13 refs.; 2 tabs.

    Stereotactic body radiotherapy (SBRT) has been shown to improve overall survival in patients with advanced hepatocellular carcinoma. This study aimed to assess the cost-effectiveness of SBRT compared to sorafenib which is the only drug for advanced hepatocellular carcinoma. A Markov decision-analytic model was performed to compare the cost-effectiveness of SBRT and sorafenib for unresectable advanced hepatocellular carcinoma. Patients transitioned between three health states: stable disease, progression disease and death. We calculated the data on cost from the perspective of our National Health Insurance Bureau. Sensitivity analyses were conducted to determine the impact of several variables. The incremental cost effectiveness ratio (ICER) for sorafenib compared to SBRT was NT$3,788,238 per quality-adjusted life year gained (cost/QALY), which was higher than the willingness to pay threshold of Taiwan according to WHO’s guideline. One-way sensitivity analysis revealed that the utility of progression disease for the sorafenib treatment, utility of progression free survival for SBRT, utility of progression free survival for sorafenib, utility of PFS to progression disease for SBRT and transition probability of progression disease to dead for SBRT were the most sensitive parameters in all cost scenarios. The Monte-Carlo simulation demonstrated that the probability of cost-effectiveness at a willingness to pay threshold of NT$ 2,213,145 per QALY was 100 % and 0 % chance for SBRT and sorafenib. This study indicated that SBRT for advanced hepatocellular carcinoma is cost-effective at a willingness to pay threshold as defined by WHO guideline in Taiwan

    Purpose: To evaluate the influence of fraction size and overall time on local control of T1 and T2 glottic carcinoma Methods and Materials: Between 1956 and 1995, 318 consecutive patients with early glottic carcinoma (250 T1, 68 T2) were treated with definitive megavoltage radiotherapy at UCSF. Treatment was delivered using conventional fractionation at one fraction/day, 5 days/week. Minimum tumor dose ranged from 50 to 81Gy (median: 61Gy). The fraction size was 200cGy. Conclusions: Risk of tumor recurrence increased with higher T-stage, smaller fraction size, and longer overall time. Our results suggest that for optimal local control, radiotherapy for early glottic carcinoma should be completed as soon as possible, preferably within 6 weeks, using a fraction size ≥ 225cGy. Our current policy is to treat T1 and T2 vocal cord carcinomas with 225cGy/fraction/day, 5 days/week to a total dose of 63-65Gy

    Cervical cancer has a major impact on the lives of Indian women with an estimated 122, 844 new cases of cervical cancer in the year 2012. About 80% of these cases present in a locally advanced stage leading to high morbidity and mortality. Because of lack of public awareness and infrastructure for screening and early detection in developing countries, this late presentation is likely to continue in the coming years. Radiation therapy has been the treatment of choice for patients with locally advanced cancer cervix. Many clinical trials and meta-analyses have shown a significant improvement in overall and progression-free survival with decreased local and distant recurrences with the use of concurrent chemotherapy with radiation. Most of these trials have been done in women from developed countries where the patient and disease profile are entirely different from ours. Recently, few trials from India have also shown promising results in locally advanced cancer cervix with concurrent chemoradiotherapy but toxicities remain a major concern. Further exploration is required for the use of concurrent chemo radiation prior to incorporating it into routine clinical practice.

    Full Text Available BACKGROUND: This study was performed to evaluate the safety and efficacy of paclitaxel with cisplatin as salvage therapy in patients previously treated with gemcitabine and cisplatin (G/C for advanced transitional cell carcinoma (TCC of the urothelial tract. METHODS: Twenty-eight patients with metastatic or locally advanced TCC who had received prior G/C chemotherapy were enrolled. All patients received paclitaxel (175 mg/m2 and cisplatin (60 mg/m2 every 3 weeks for eight cycles or until disease progression. RESULTS: The median age was 61 years (range, 43–83 years, and the median Eastern Cooperative Oncology Group performance status was 1 (range, 0–2. The overall response rate was 36% [95% confidence interval (95% CI = 18–54], with three complete responses and seven partial responses. The median time to progression was 6.2 months (95% CI = 3.9–8.5, and the median overall survival was 10.3 months (95% CI = 6.1–14.1. The most common Grade 3/4 nonhematologic and hematologic toxicities were emesis (10 of 28 patients; 36% and neutropenia (5 of 110 cycles; 5%. CONCLUSIONS: Salvage chemotherapy with paclitaxel and cisplatin displayed promising results with tolerable toxicity profiles in patients with metastatic or locally advanced TCC who had been pretreated with G/C.

    Renal cell carcinoma (RCC) is rare in children and comprises only 1-3% of all pediatric primary renal tumors. Recently, several case reports have described RCC developing in patients previously treated for advanced stage neuroblastoma (NB). Our experience with four patients treated for advanced stage NB during early childhood who developed RCC later in life are added to 14 others in the literature. These patients and our review of the literature suggest an association between RCC and NB that warrants further study. (orig.)

    We analyzed the trends in presentation of squamous cell carcinoma (SCC) of the penis and determined the socioeconomic predictors for locally advanced (cT3-cT4) disease in the United States. The National Cancer Database was queried for patients with clinically nonmetastatic penile SCC and staging available from 1998 to 2012. Temporal trends per tumor stage were evaluated, and a multivariable logistic regression model was used to identify predictors for advanced presentation during the study period. A total of 5767 patients with stage ≤ T1-T2 (n = 5423) and T3-T4 (n = 344) disease were identified. Increasing trends were noted in all stages of penile SCC with a greater proportion of advanced cases over time (P = .001). Significant predictors of advanced presentation were age > 55 years, the presence of comorbidities, and Medicaid or no insurance (P guide targeted interventions in vulnerable populations.

    Purpose: To summarize biochemical failure rates and morbidity of external beam irradiation (EBRT) combined with palladium ( 103 Pd) boost for clinically localized high-risk prostate carcinoma. Methods and Materials: Seventy-three consecutive patients with stage T2a-T3 prostatic carcinoma were treated from 1991 through 1994. Each patient had at least one of the following risk factors for extracapsular disease extension: Stage T2b or greater (71 patients), Gleason score 7-10 (40 patients), prostate specific antigen (PSA) >15 (32 patients), or elevated prostatic acid phosphatase (PAP) (17 patients). Patients received 41 Gy EBRT to a limited pelvic field, followed 4 weeks later by a 103 Pd boost (prescription dose: 80 Gy). Biochemical failure was defined as a PSA greater than 1.0 ng/ml (normal 103 Pd brachytherapy for clinically localized, high-risk prostate cancer compare favorably with that reported after conventional dose EBRT alone. Morbidity has been acceptable

    Local therapies such as radiofrequency ablation (RFA) represent a valuable choice in limited hepatocellular carcinoma (HCC) and are increasingly used also in advanced tumors. Medical treatments generally gave frustrating results in advanced HCC especially if comorbidities exist. Several biologic non-chemotherapeutic drugs are currently tested in HCC and, among them, octreotide was evaluated in single series of HCC patients reporting conflicting results. We have treated a series of 35 patients affected by advanced HCC (26 M and 9 F; age range: 55-85 years, median: 73 years) with RFA followed by octreotide to primarily evaluate the safety of combined treatment and to give preliminary evaluation on its activity. We have also evaluated serum VEGF changes during the study. Child A and Child B represented 60% and about 34% of the cases, respectively. Only two patients with Child C compensated cirrhosis were included in this study. All patients have multiple liver HCC nodules and one had bone metastases. Two complete responses, 3 partial responses and 23 disease stabilization for at least three months were obtained (overall response rate, 14,2%; clinical benefit, 80%). Mean overall survival was 31.4 months. The combined treatment was well tolerated. Statistically significant correlation was found between serum VEGF and tumor progression. In conclusion, the combination of RFA and octreotide was active in advanced HCC, however, confirmation in a larger series is required.

    To determine the prognostic factors for local recurrence of nodular hepatocellular carcinoma after segmental transarterial chemoembolization. Seventy-four nodular hepatocellular carcinoma tumors ≤5 cm were retrospectively analyzed for local recurrence after segmental transarterial chemoembolization using follow-up CT images (median follow-up of 17 months, 4 77 months in range). The tumors were divided into four groups (IA, IB, IIA, and IIB) according to whether the one-month follow-up CT imaging, after segmental transarterial chemoembolization, showed homogeneous (Group I) or inhomogeneous (Group II) iodized oil accumulation, or whether the tumors were located within the liver segment (Group A) or in a segmental border zone (Group B). Comparison of tumor characteristics between Group IA and the other three groups was performed using the chi-square test. Local recurrence rates were compared among the groups using the Kaplan-Meier estimation and log rank test. Local tumor recurrence occurred in 19 hepatocellular carcinoma tumors (25.7%). There were: 28, 18, 17, and 11 tumors in Group IA, IB, IIA, and IIB, respectively. One of 28 (3.6%) tumors in Group IA, and 18 of 46 (39.1%) tumors in the other three groups showed local recurrence. Comparisons between Group IA and the other three groups showed that the tumor characteristics were similar. One-, two-, and three-year estimated local recurrence rates in Group IA were 0%, 11.1%, and 11.1%, respectively. The difference between Group IA and the other three groups was statistically significant (p 0.000). An acceptably low rate of local recurrence was observed for small or intermediate nodular tumors located within the liver segment with homogeneous iodized oil accumulation

    While numerous surveys of pattern of practices of palliative radiotherapy (RT) in advanced esophageal cancers have been published in developed countries, there is no such survey in African countries. During and after a regional training course by the International Atomic Energy Agency (IAEA) in palliative cancer care, a questionnaire was distributed to African RT centers to gather information about infrastructure and human resources available, and the pattern of practice of palliative RT for esophageal cancers. Twenty-four of the 35 centers (60%) completed the questionnaire. Twenty out of 23 (87%) centers treat patients with esophageal cancer presenting with dysphagia using external beam RT (16 centers external beam RT alone and 4 centers also use brachytherapy as a boost). Twelve (60%) centers prescribe RT doses of 30 Gy in 10 fractions and 2 centers 20 Gy in 5 fractions. Eighteen centers (78%) have low dose rate (LDR) brachytherapy, and 9 (39%) centers have high dose rate (HDR) brachytherapy. One center only used HDR brachytherapy alone to a dose of 16 Gy in 2 fractions over 8 days. RT remains a major component of treatment of patients with esophageal cancers in African countries. Still, there is a great variety among centers in both indications for RT and its characteristics for a treatment indication.

    Full Text Available Hepatocellular carcinomas are highly vascular tumors, showing progressive hypervascularity by the process of neoangiogenesis. Tumor angiogenesis is critical for tumor growth as well as metastatic spread therefore, imaging and quantification of tumor neo-angiogenesis is essential for monitoring response to targeted therapies and predicting disease progression. Sorafenib is a molecular targeting agent used for treating hypervascular tumors. This drug is now the standard of care in treatment of patients with advanced hepatocellular carcinoma. Due to its anti-angiogenic and anti-proliferative actions, imaging findings following treatment with Sorafenib are quite distinct when compared to conventional chemotherapeutic agents. Liver MRI is a widely adopted imaging modality for assessing treatment response in hepatocellular carcinoma and imaging features may reflect pathophysiological changes within the tumor. In this mini-review, we will discuss MRI findings after Sorafenib treatment in hepatocellular carcinoma and review the feasibility of MRI as an early biomarker in differentiating responders from non-responders after treatment with molecular targeting agents.

  16. Which features of advanced head and neck basal cell carcinoma are associated with perineural invasion?

    André Bandiera de Oliveira Santos

    Full Text Available Abstract Introduction Perineural invasion is a unique route for tumor dissemination. In basal cell carcinomas, the incidence is low, but increases in advanced cases. Its importance is recognized but not fully understood. Objective To compare head and neck basal cell carcinomas with and without perineural invasion. Methods A retrospective medical chart review of multidisciplinary surgeries for basal cell carcinomas that required a head and neck surgery specialist in a tertiary referral center was performed. Clinical-demographics and histopathological features were analyzed. Results Of 354 cases, perineural invasion was present in 23.1%. Larger tumors and morpheaform subtype were statistically related to perineural invasion. Nodular and superficial subtypes were less frequent in positive cases. No significant difference was found in gender, age, ulceration, location, and mixed histology. Conclusion In this series of selected patients with basal cell carcinomas submitted to major resections, perineural invasion was clearly related to morpheaform subtype and to larger tumors. Other classically associated features, such as location in high-risk mask zone of the face, male gender and mixed histology, were not so strongly linked to perineural invasion.

    Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

    Induction chemoradiotherapy (CRT) may down-stage locally advanced pancreatic tumors but secondary resections are unfrequent. However some responders' patients may benefit of a RO resection. Patients and methods. We report 18 resections among 29 locally advanced pancreatic cancers; 15 patients were treated with neo-adjuvant 5-FU-cisplatin based (13) or taxotere based (2 patients) chemoradiotherapy (45 Gy), and 3 patients without histologically proven adenocarcinoma were resected without any preoperative treatment. Results. The morbidity rate was 28% and the mortality rate was 7%; one patient died after resection (5.5%) and one died after exploration (9%). The RO resection rate was 50%. The median survival for the resected patients was not reached and the actuarial survival at 3 years was 59%. Two specimens showed no residual tumor and the two patients were alive at 15 and 46 months without recurrence; one specimen showed less than 10% viable tumoral cells and the patient was alive at 36 months without recurrence. A mesenteric infarction was the cause of a late death at 3 years in a disease free patient (radiation induced injury of the superior mesenteric artery). The median survival of the 11 non-resected patients was 21 months and the actuarial survival at 2 years was 0%. When the number of the resected patients (18) was reported to the entire cohort of the patients with locally advanced pancreatic cancer treated during the same period in our institution, the secondary resectability rate was 9%. Conclusion. Preoperative chemoradiotherapy identifies poor surgical candidates through observation and may enhance the margin status of patients undergoing secondary resection for locally advanced tumors. However it remains difficult to evaluate the results in the literature because of the variations in the definitions of resectability. The best therapeutic strategy remains to be defined, because the majority of patients ultimately succumb with distant metastatic disease

    Objective: to assess the treatment of breast cancer T2 and T3(T > = 4 cm), through neoadjuvant chemotherapy, quadrantectomy and high-dose-rate (HDR) brachytherapy as a boost, complementary radiotherapy and adjuvant chemotherapy, considering its method problems, its esthetics results, the aspect of local control, overall survival, and disease-free survival. Patients and method: this clinical prospective descriptive study was based on the evaluation of 26 patients ranging from 30 to 70 years old, with infiltrating ductal carcinoma, clinical stage IIB and IIIA, responsive to the neoadjuvant chemotherapy. Early and late radiotherapy complications were evaluated according to the criteria established by the RTOG/EORTC (Radiotherapy and Oncology Group /European Organization for Research and Treatment of Cancer) groups. Esthetics evaluation was done in accordance with the criteria set by a plastic surgeon. Local control was evaluated by clinical method, mammography and ultrasonography. Overall survival (OS) and the disease-free survival (DFS) were assessed according to Kaplan-Meier methodology. All the patients were treated at the Dr. Arnaldo Vieira de Carvalho Cancer Institute, from June/1995 to November/2001, and evaluated in March, 2002, with median follow-up of 28.7 months. Results: early complications were observed in 8 patients (30.6%). Two patients were classified as G3 and G4 (RTOG/EORTC). Six patients had late complications and three of them (11.5%) were classified as G3 and G4. One patient (3.8%) had local recurrence, 64 months after having local treatment. Esthetics results were considered good or regular in 16 patients (60.5%) out of 24 patients who were examined. Overall survival and disease-free survival in 24, 36 and 60 months were 100%, 92.3% and 83.1% respectively. Conclusion: early and late radiotherapy complications were considerate high when compared to literature, but esthetic results were considered acceptable. RL, OS and DFS were comparable to other

    The aim of investigation is to improve surgical treatment of patients with locally advanced pelvic cancer. The basis of investigation is 186 patients with locally advanced pelvic cancer. The average age of patients is 65.2 ± 5.2 years (from 43.7 to 88.4 years). Among them are 112 women and 74 men. In the period from 2007 to 2015 they were carried out combined (101 patients) and expanded (85 patients) surgical intervention in the department of naval surgery of the Military medical academy after S.M.Kirov. Pelvic evisceration was performed in 63 cases. Both patients were performed isolated vascular hyperthermic chemical pelvic perfusion. Indications for plastic surgery of peritoneum pelvic were: total infralitoral pelvic evisceration (9 patients), dorsal infralitoral pelvic evisceration (11 cases) and expanded abdominoperineal rectum extirpation (34 patients). Plastic surgery with autogenouse tissues was performed to 43 patients, with reticulate explants--to 11 patients. The rate of postoperative complications was 40.2%. The rate of postoperative lethality was 8%. Expanded and combined operations of pelvic at patients with locally advanced cancer without absolute contra-indications can be performed irrespective of age. Plastic surgery of peritoneum pelvic after total and dorsal infralitoral pelvic evisceration and expanded abdominoperineal rectum extirpation indicated in all cases. The easiest method is plastic surgery with greater omentum or peritoneum pelvic. Plastic surgery with reticulate explants is performed when autoplastic is impossible.

    The SafeTy Events in VIsmodEgib study (STEVIE, ClinicalTrials.gov, NCT01367665), assessed safety and efficacy of vismodegib-a first-in-class Hedgehog pathway inhibitor demonstrating clinical benefit in advanced basal cell carcinoma (BCC)-in a patient population representative of clinical practice. Primary analysis data are presented. Patients with locally advanced or metastatic BCC received oral vismodegib 150 mg/d until progressive disease, unacceptable toxicity, or withdrawal. Primary objective was safety. Efficacy variables were assessed as secondary end-points. Evaluable adult patients (N = 1215, 1119 locally advanced; 96 metastatic BCC) from 36 countries were treated; 147 patients (12%) remained on study at time of reporting. Median (range) treatment duration was 8.6 (0-44) months. Most patients (98%) had ≥1 treatment-emergent adverse event (TEAE). The incidence of the most common TEAEs was consistent with reports in previous analyses. No association between creatine phosphokinase (CPK) abnormalities and muscle spasm was observed. Serious TEAEs occurred in 289 patients (23.8%). Exposure ≥12 months did not lead to increased incidence or severity of new TEAEs. The majority of the most common TEAEs ongoing at time of treatment discontinuation resolved by 12 months afterwards, regardless of Gorlin syndrome status. Response rates (investigator-assessed) in patients with histologically confirmed measurable baseline disease were 68.5% (95% confidence interval (CI) 65.7-71.3) in patients with locally advanced BCC and 36.9% (95% CI 26.6-48.1) in patients with metastatic BCC. The primary analysis of STEVIE demonstrates that vismodegib is tolerable in typical patients in clinical practice; safety profile is consistent with that in previous reports. Long-term exposure was not associated with worsening severity/frequency of TEAEs. Investigator-assessed response rates showed high rate of tumour control. CLINICALTRIALS.GOV: NCT01367665.

    Objective: To evaluate the effect of transcatheter arterial chemoembolization (TACE) together with portal vein chemoembolization (PVCE) for the treatment of advanced liver carcinomas. Methods: Forty-eight patients with liver carcinoma were randomly divided into two groups. Patients in study group (n = 22) were treated with TACE together with PVCE, and patients in control group (n = 26) were treated with TACE alone. Results: Based on the postoperative CT findings and AFP levels, the effective rate of the study group was markedly higher than that of control group and the difference between two groups was statistically significant (P < 0.05). The volume of un-embolized liver tissue in the patients of study group was obviously increased after treatment. Conclusion: TACE together with PVCE is superior to TACE alone in treating advanced hepatic carcinomas. The combination of TACE and PVCE can effectively increase the successful rate of surgical resection for the advanced hepatic carcinomas. (authors)

    Chemotherapy combined with radiotherapy can improve outcome in locally advanced esophageal cancer. This study aimed to compare efficacy and toxicity between concurrent chemoradiotherapy (CCRT) and sequential chemoradiotherapy (SCRT) in unresectable, locally advanced, esophageal squamous cell carcinoma (ESSC). Forty-one patients with unresectable, locally advanced ESCC were randomized into two arms. In the CCRT arm (Arm A), 17 patients received 50.4 Gy at 1.8 Gy per fraction over 5.6 weeks along with concurrent cisplatin (75 mg m(-2) intravenously on day 1 and 5-fluorouracil (1000 mg m(-2) continuous intravenous infusion on days 1-4 starting on the first day of irradiation and given after 28 days. In the SCRT arm (Arm B), 20 patients received two cycles of chemotherapy, using the same schedule, followed by radiotherapy fractionated in a similar manner. The endpoints were tumor response, acute and late toxicities, and disease-free survival. With a median follow up of 12.5 months, the complete response rate was 82.4% in Arm A and 35% in Arm B (P = 0.003). Statistically significant differences in frequencies of acute skin toxicity (P = 0.016), gastrointestinal toxicity (P = 0.005) and late radiation pneumonitis (P = 0.002) were found, with greater in the CCRT arm. A modest but non-significant difference was observed in median time to recurrence among complete responders in the two arms (Arm A 13 months and Arm B 15.5 months, P = 0.167) and there was also no significant difference between the Kaplan Meier survival plots (P = 0.641) of disease-free survival. Compared to sequential chemoradiotherapy, concurrent chemoradiotherapy can significantly improve local control rate but with greater risk of adverse reactions.

    IL-1beta has been implicated in inflammatory episode. In view of the inflammatory nature of cancer cachexia, we determined the predictive value of IL-1B-31 T/C, -511 C/T, +3954 C/T and IL-1RN VNTR gene polymorphisms on the occurrence of cachexia associated with locally advanced gastric cancer. The study included 214 patients and 230 healthy volunteers. Genomic DNA was prepared from peripheral blood leukocytes. Genotypes and allele frequencies were determined in patients and healthy controls using restriction fragment length polymorphism analysis of polymerase chain reaction products. The overall frequencies of IL-1B-31 T, -511 T, +3954 T and IL-1RN VNTR alleles in patients with locally advanced gastric cancer were all comparable with those in controls. No significant differences were found in the distribution of IL-1B-31 T, -511 T and IL-1RN VNTR between patients with cachexia and without. Patients with cachexia showed a significantly higher prevalence of IL-1B+3954 T allele than those without (P = 0.018). In a logistic regression analysis adjusted for actual weight, carcinoma location and stage, the IL-1B+3954 CT genotype was associated with an odds ratio of 2.512 (95% CI, 1.180 – 5.347) for cachexia. The IL-1B+3954 T allele is a major risk for cachexia from locally gastric cancer. Genetic factors studied are not likely to play an important role in the determination of susceptibility to locally advanced gastric cancer.

    Esophageal carcinoma has a special place in gastrointestinal carcinomas because it contains two main types, namely, squamous cell carcinoma and adenocarcinoma. Carcinoma esophagus patients require some form of palliation because of locally advanced stage or distant metastasis, where it cannot be subjected to curable treatment with surgery and chemoradiation. Many modalities of palliation of dysphagia are available, but the procedure with least morbidity, mortality, and long-term palliation of...

    Renal Cell Carcinoma (RCC) accounts for approximately 4 % of all malignancies. Much is known about the pathogenesis of RCC because of studies examining its close relationship with dysfunction of the Von Hippel-Lindau gene (VHL) and hypoxia inducible factor (HIF). Mammalian target of rapamycin (mTOR) regulates nutritional needs, cell growth, and angiogenesisi in cells by down regulating or up regulating a variety of proteins including HIF. Until 2005, only a single agent high dose interleukin 2 was approved by Food and Drug Administration (FDA) for treatment of advanced renal cell carcinoma. More recently thanks to better knowledge in the field of molecular biology new treatment options appeared. Sunitinib and bevacizumab are currently considered to be treatment of first choice for patients in good and intermediate prognostic group and sorafenib is preferred second line treatment in the same patient population pretreated with cytokines after disease progression. Temsirolimus and everolimus, rapamycin analouges, have recently been tested in III trials in first and second line treatment in patients with advanced metastatic clear cell renal cell carcinoma.

    Objective: To evaluate the efficacy and toxicity of gemcitabine plus cisplatin (GP) chemotherapy combined with intensity-modulated radiation therapy (IMRT) in locoregionally advanced nasopharyngeal carcinoma (NPC). Methods: 71 patients (Stage III: 41, Stage IV A : 30) with locoregionally advanced NPC were entered this study. Neoadjuvant chemotherapy was consisted of cisplatin 25 mg/m 2 intravenously on d1-3 and gemcitabine 1000 mg/m 2 in 30 minutes intravenous infusion on days 1 and 8, every 3 weeks for 2 cycles. Adjuvant chemotherapy consisted of 2 cycles of the same GP regimen was given at 28 days after the end of radiotherapy. The prescription doses was 66.0-70.4 Gy to the gross tumor volume, 66 Gy to positive neck nodes, 60 Gy to the high-risk clinical target volume, 54 Gy to the low-risk clinical target volume. Results: The overall response rate to neoadjuvant chemotherapy was 91.2%, acute toxicity was mainly grade 1-2 myleosuppression. All patients completed IMRT. The median follow-up duration was 38 months. The 3-year nasopharyngeal local control, regional control, distant metastasis-free survival rate and overall survival rate were 93%, 99%, 91%, 90%, respectively. Severe late toxicities included grade 3 trismus in 1 patient, grade 3 hearing impairment in 2 patients and cranial nerve palsy in 2 patients, respectively. No grade 4 late toxicities were observed. Conclusions: The combination of GP chemotherapy and IMRT for locoregionally advanced nasopharyngeal carcinoma is well-tolerated, convenient, effective, and warrants further studies of more proper cycles of GP regimen.

    Full text: In advanced prostatic cancer, hyperthermia may be useful in order to enhance irradiation efficacy so to avoid delivering of too high dose of radiotherapy which increases acute and late sequelae. A multi-centric phase II study is warranted to give hyperthermia a level 3 evidence in prostate cancer treatment. A randomized phase III study to demonstrate efficacy of hyperthermia is not available because of the optimal results obtained by using radiotherapy combined with androgen suppression. To evaluate hyperthermia gain, LHT should be combined with radiotherapy alone in patients refusing androgen suppression or affected by hormone refractory prostate carcinoma (HRPC). Patients with HRPC have multiple possibilities of treatment improving performance status and median survival, as chemotherapy regimens, and new agents. All these treatments modalities need to be confirmed by phase III trials. Also hyperthermia may be considered among these promising approaches. (author)

    The objectives of this study were to assess the long-term outcome and the risk for local recurrence of patients with small cell carcinoma of the bladder (SCCB) treated with neoadjuvant chemotherapy followed by external beam radiotherapy (sequential chemoradiation). All consecutive patients with primary small cell carcinoma of the bladder (n=66), treated in our institution between 1993 and 2011 were retrospectively evaluated from an institutional database. Only patients with limited disease (Tx-4N0-1M0) small cell carcinoma of the bladder treated with sequential chemoradiation (n=27) were included in this study. Recurrence rates, overall survival and cancer-specific survival were analyzed using the Kaplan-Meier method. Median time to recurrence was 20 months, median overall survival 26 months, 5-year overall survival 22.2%, median cancer-specific survival 47 months and 5-year cancer-specific survival 39.6%. For complete responders after neoadjuvant chemotherapy (n=19), median cancer-specific survival was 52 months with a 5-year cancer-specific survival 45.9% versus a median cancer-specific survival of 22 months and 5-year cancer-specific survival 0.0% for incomplete responders (n=8; P=0.034). Eight patients (29.6%) underwent transurethral resections (TUR-BT) for local recurrences in the bladder. At the end of follow up, four patients had undergone cystectomy for recurrence of disease resulting in a bladder-preservation rate of 85.2%. Median time to local recurrence was 29 months and median time to distant recurrence was 10 months. Sequential chemoradiation for limited disease small cell carcinoma of the bladder results in a reasonable outcome with a high bladder preservation rate. Response to neoadjuvant chemotherapy represents a significant prognostic factor in this patient population. (author)

    The aim of the study was to characterize CT images and stages of carcinomas localized in the antral part of the stomach obtained with spiral CT. Seven men aged from 54 years old to 81 years old inclusive, with subjective complaints and clinical suspicion of a neoplasm in the upper gastrointestinal tract were examine Examinations were performed following stomach wall re relaxation with Buscolysin.The stomach is distended by drinking 600 ml of water. Upper abdomen scans were performed with spiral CT/e General Electric with the following parameters: slice thickness 3-5 mm, spacing 3 mm, pitch 1,5, reconstruction index 3 mm. After the pre-contrast scans, 100 ml of non-ionic contrast media is administered intravenously with an injection rate of 30 ml/sec. Scan delay time - 30 seconds after start of injection. Exposition data-120 kV, 180 mAs. Carcinoma localized in the antral part of the stomach was demonstrated in 7 patients. The staging showed: I stage - one patient, II stage - 2, III stage - 1 and IV stage - three patients. According to the macro morphological characteristic: exophytic type - 4, endophytic tumor - 1, ulcerous tumor - 1 and early carcinoma - 1 patient. In our material only male patients were present. Early carcinoma was demonstrated in a male patient at an age of 80 years old. An enhancing nodular local thickness was visualized. Differential diagnosis between malignant and benign ulcer is necessary in certain cases. It is performed on the contrast scans, the malignant process enhances twice its density, When performing a purposive CT examination it is possible to diagnose neoplasms in the antral part of the stomach, from stage i to IV with different macro morphologic characteristic

    Pretreatment tables for the prediction of pathologic stage have been published and validated for localized prostate cancer (PCa). No such tables are available for locally advanced (cT3a) PCa. To construct tables predicting pathologic outcome after radical prostatectomy (RP) for patients with cT3a PCa with the aim to help guide treatment decisions in clinical practice. This was a multicenter retrospective cohort study including 759 consecutive patients with cT3a PCa treated with RP between 1987 and 2010. Retropubic RP and pelvic lymphadenectomy. Patients were divided into pretreatment prostate-specific antigen (PSA) and biopsy Gleason score (GS) subgroups. These parameters were used to construct tables predicting pathologic outcome and the presence of positive lymph nodes (LNs) after RP for cT3a PCa using ordinal logistic regression. In the model predicting pathologic outcome, the main effects of biopsy GS and pretreatment PSA were significant. A higher GS and/or higher PSA level was associated with a more unfavorable pathologic outcome. The validation procedure, using a repeated split-sample method, showed good predictive ability. Regression analysis also showed an increasing probability of positive LNs with increasing PSA levels and/or higher GS. Limitations of the study are the retrospective design and the long study period. These novel tables predict pathologic stage after RP for patients with cT3a PCa based on pretreatment PSA level and biopsy GS. They can be used to guide decision making in men with locally advanced PCa. Our study might provide physicians with a useful tool to predict pathologic stage in locally advanced prostate cancer that might help select patients who may need multimodal treatment.

    To review the experience and to evaluate the treatment plan of using helical tomotherapy (HT) for the treatment of cervical cancer. Between November 1st, 2006 and May 31, 2009, 10 cervical cancer patients histologically confirmed were enrolled. All of the patients received definitive concurrent chemoradiation (CCRT) with whole pelvic HT (WPHT) followed by brachytherapy. During WPHT, all patients were treated with cisplatin, 40 mg/m 2 intravenously weekly. Toxicity of treatment was scored according to the Common Terminology Criteria for Adverse Events v3.0 (CTCAE v3.0). The mean survival was 25 months (range, 3 to 27 months). The actuarial overall survival, disease-free survival, locoregional control and distant metastasis-free rates at 2 years were 67%, 77%, 90% and 88%, respectively. The average of uniformity index and conformal index was 1.06 and 1.19, respectively. One grade 3 of acute toxicity for diarrhea, thrombocytopenia and three grade 3 leucopenia were noted during CCRT. Only one grade 3 of subacute toxicity for thrombocytopenia was noted. There were no grade 3 or 4 subacute toxicities of anemia, leucopenia, genitourinary or gastrointestinal effects. Compared with conventional whole pelvic radiation therapy (WPRT), WPHT decreases the mean dose to rectum, bladder and intestines successfully. HT provides feasible clinical outcomes in locally advanced cervical cancer patients. Long-term follow-up and enroll more locally advanced cervical carcinoma patients by limiting bone marrow radiation dose with WPHT technique is warranted

    The aim of this study is to examine the therapeutic effects and adverse events of preoperative chemoradiation therapy (CRT) for locally advanced rectal cancer in different radiation doses and fractions. A total of 142 consecutive patients with locally advanced (cT3-4 and/or cN1-2) adenocarcinoma of the rectum were treated with preoperative CRT and were operated radically. 121 patients with resectable cT3 or N1-2 rectal adenocarcinoma were assigned to receive pelvic radiation with single fractions of 2.5 Gy twice daily to a total dose of 25 Gy (Short CRT). Surgery was undergone within two weeks. 21 patients with clinical unresectable or marginally resectable cT4 rectal cancer were assigned to receive preoperative pelvic radiation therapy 45 to 50.4 Gy at 1.8 Gy per day. Surgery was performed 6 to 8 weeks after completion of neoadjuvant therapy (Long CRT). We examined retrospectively the preoperative therapeutic effect and adverse event of Short CRT and Long CRT. Short CRT; Overall R0 resection rate was 98%. Anus preserving rate was 95%. pCR rate was 5%. Median follow-up was 62 months. The actuarial 5-year-local-control rate was 94%. Overall survival for 5 years was 92%. Long neoadjuvant chemoradiation therapy (NCRT); Overall R0 resection rate was 90%. Anus preserving rate was 86%. pCR rate was 24%. Median follow-up was 60 months. The actuarial 5-year-local-control rate was 88%. Overall survival rate for 5 years was 88%. Radiation related adverse event such as pelvic infection and skin trouble was significantly higher in the long CRT group. Local control in primarily resectable rectal cancer after short chemoradiation was excellent. Long chemoradiation for unresectable or marginal cT4 rectum cancer was higher response ratio, but induced more radiation related adverse event than short course CRT. (author)

    Locally advanced colon cancer with direct abdominal wall and skin invasion is an extremely rare finding with most data being derived from case reports, historical autopsy-based or single-center retrospective studies. We present a unique case of a colon cancer with direct cutaneous invasion and colocutaneous fistulization. Eighty-six year old Caucasian female with multiple comorbidities, referred to Surgical Consultation due to ulcerated skin lesion in the abdomen. She had a long-standing large umbilical hernia but with no previous episodes of incarceration or occlusive symptoms. She denied any digestive or constitutional symptoms. Physical examination showed a large non-reducible umbilical hernia, with an associated painless firm mass within the hernia sac and cutaneous ulcerated growth. Colonoscopy revealed transverse colon cancer (endoscopic biopsy of the tumor and skin punch biopsy confirmed adenocarcinoma of the colon). Computed tomography showed a tumoral mass within the umbilical hernia, with cutaneous infiltration and enlarged regional lymph nodes. Rapid local progression led to colocutaneous fistula with total fecal diversion. We performed an extended right hemicolectomy with en bloc excision of the hernia sac and infiltrating cutaneous mass. In the current era of widespread use of screening colonoscopies, initial diagnosis of locally advanced colon cancer is decreasing. However, this unique case presented an opportunity to recall the advantages of multivisceral resections.

    Full Text Available A malignant transformation is known to occur in many nevi such as a sebaceous nevus or a basal cell nevus, but a verrucous epidermal nevus has only rarely been associated with neoplastic changes. Keratoacanthoma, multifocal papillary apocrine adenoma, multiple malignant eccrine poroma, basal cell carcinoma and cutaneous squamous cell carcinoma (CSCC have all been reported to develop from a verrucous epidermal nevus. CSCC has also been reported to arise from other nevoid lesions like a nevus comedonicus, porokeratosis, a sebaceous nevus, an oral sponge nevus and an ichthyosiform nevus with CHILD syndrome. Here we report a case of progressive poorly differentiated CSCC arising from a localized verrucous epidermal nevus, which caused both spinal cord and brain metastasis.

    Full Text Available The paper describes a clinical case of a local recurrence of tubulocystic carcinoma (TCC in a 46-year-old man, a relatively good course (the relapse occurred after 4 years, who has been successfully operated on and is being followed up. This disease is a rare renal malignancy and, until recently, it has been referred to as collecting tubular carcinoma. However, this disease has come to be regarded as an independent nosological entity, by taking into account its certain morphological, immunohistohemical, and cytogenetic characteristics, as well as the nature of its course. About 80 TCC cases have been described to date. Further study of this disease and other rare renal malignancies will allow the more accurate elaboration of management tactics for such patients in terms of certain prognostic factors, which calls for a larger number of cases of this disease.
