    Metastases to the brain occur in 25 to 35% of patients with systemic cancer. Cerebral metastatic is the most common intracranial tumor in adults and occur up to 10 times more frequently than primary tumors in the central nervous system. Significant advances have occurred in the diagnosis and treatment of metastases to the brain, and the therapeutic nihilism of the past is now no longer warranted for most patients. With the currently available treatments, most patients do not die of their brain metastases and usually experience effective palliation of neurologic symptoms and meaning full extension of life. As a trial to limit the cerebral metastatic disease, many and diverse therapy options have been developed such as: chemotherapy, surgery plus whole-brain radiotherapy, only radiation therapy, therapy with neutron, intersticial brachytherapy and stereotactic radiosurgery. In selected cases, surgery plus whole-brain radiotherapy is the conventional treatment for single metastases. However, recurrence usually limits the quality of life and greatly decrease the patients time life, and the therapy options are scarce. This piece of writing also includes a review of the available therapy forms to manage this kind of lesions. (The author)

    We compared concurrent combination chemoradiotherapy and adjuvant radiotherapy after laser surgery in patients with stage 3/4 non metastatic squamous cell head and neck cancer. Combination chemotherapy and concurrent irradiation after laser surgery was not superior to surgery and postoperative radiotherapy for resectable advanced squamous cell head and neck cancer. However, the collective is small, and the follow-up to short to conclude. (authors)

    In locally advanced oral cancer, the main modalities of treatment, e.g. surgery and radiotherapy, most often fail to control the disease when used singly. A combination policy of surgery and radiotherapy achieves adequate control of the disease. In order to improve the results in advanced oral cancer, chemotherapy given prior to and during radiation treatment and judicious combination of surgery offer the best possible approach in the management. The experience in the combination policy in the treatment of oral cancer in Northern India is dealt with. (auth.)

    Primary or neoadjuvant chemotherapy prior to definitive local therapy has potential advantages for locally advanced cervix cancer. It can down stage a cancer and allow definitive local therapy to be technically possible (surgery), or potentially more effective (radiotherapy). It can also eradicate subclinical systemic metastases. This report reviews a single institution's experience of neoadjuvant chemotherapy prior to definitive local therapy for cervix cancer over a 13-year period. One hundred and six patients were treated with this intent. The patients were analysed for their response to chemotherapy, treatment received, survival, relapse and toxicity. The chemotherapy was feasible and the majority of patients had a complete or partial response (58.5%). Eight patients did not proceed to local treatment. Forty-six patients had definitive surgery and 52 had definitive radiotherapy. The 5-year overall survival was 27% and the majority of patients died with disease. The first site of relapse was usually in the pelvis (46.2%). Late complications that required ongoing medical therapy (n = 6) or surgical intervention (n = 2) were recorded in eight patients (7.5%). On univariate analysis stage (P= 0.04), tumour size (P = 0.01), lymph node status (P=0.003), response to chemotherapy (P = 0.045) and treatment (P = 0.003) were all significant predictors of survival. On multivariate analysis, tumour size (P < 0.0001) and nodal status (P = 0.02) were significant predictors of survival. Despite the impressive responses to chemotherapy of advanced cervix cancer, there is evidence from randomized trials that it does not improve or compromise survival prior to radiotherapy. As its role prior to surgery remains unclear, it should not be used in this setting outside a prospective randomized trial. Copyright (2001) Blackwell Science Pty Ltd

    Full Text Available Abstract Introduction Pulmonary artery intimal sarcoma is a rare disease with no characteristic symptoms. It is difficult to diagnose early and is frequently misdiagnosed as a pulmonary embolism. Case presentation Here we report a case of pulmonary artery intimal sarcoma in a 54-year-old woman presenting with complaints of shortness of breath on exertion. Echocardiography and a computed tomography scan showed that the right pulmonary artery trunk was blocked by a low-density mass. The patient was diagnosed with pulmonary artery intimal sarcoma by pathology and a complete mass resection was performed. After experiencing 10 months of disease-free survival, she was re-admitted because of the recurrence and metastasis of the tumor. Radiotherapy and chemotherapy were performed; however, only limited success was achieved. The patient died 15 months after the initial onset of symptoms. Conclusion Some patients with intimal sarcoma of the pulmonary artery can benefit from radiotherapy and chemotherapy as well as surgery.

    To evaluate the treatment outcomes of patients with locally advanced rectal cancer treated with preoperative concurrent chemoradiotherapy (CCRT) or combined chemotherapy together with radiotherapy (CMTRT) without surgery. A total of 84 patients with locally advanced rectal adenocarcinoma (stage II or III) between January 1st, 2003 and December 31st, 2013 were enrolled, 48 treated with preoperative CCRT (Gr.I) and 36 with combined chemotherapy and radiotherapy (CMTRT) without surgery (Gr.II). The chemotherapeutic agents used concurrent with radiotherapy were either 5fluorouracil short infusion plus leucovorin and/or capecitabine or 5fluorouracil infusion alone. All patients received pelvic irradiation. There were 5 patients (10.4%) with a complete pathological response. The 3 yearoverall survival rates were 83.2% in Gr.I and 24.8 % in Gr.II (prectal cancer demonstrated that in preoperative CCRT a sphincter sparing procedure can be performed. The results of treatment with preoperative CCRT for locally advanced rectal cancer showed comparable rates of overall survival and sphincter sparing procedures as compared to previous studies.

    The use of targeted intraoperative radiotherapy (TARGIT-IORT) as a tumour bed boost during breast-conserving surgery (BCS) for breast cancer has been reported since 1998. We present its use in patients undergoing breast conservation following neoadjuvant therapy (NACT). In this retrospective study involving 116 patients after NACT we compared outcomes of 61 patients who received a tumour bed boost with IORT during lumpectomy versus 55 patients treated in the previous 13 months with external (EBRT) boost. All patients received whole breast radiotherapy. Local recurrence-free survival (LRFS), disease-free survival (DFS), distant disease-free survival (DDFS), breast cancer mortality (BCM), non-breast cancer mortality (NBCM) and overall mortality (OS) were compared. Median follow up was 49 months. The differences in LRFS, DFS and BCM were not statistically significant. The 5-year Kaplan-Meier estimate of OS was significantly better by 15% with IORT: IORT 2 events (96.7%, 95%CI 87.5-99.2), EBRT 9 events (81.7%, 95%CI 67.6-90.1), hazard ratio (HR) 0.19 (0.04-0.87), log rank p = 0.016, mainly due to a reduction of 10.1% in NBCM: IORT 100%, EBRT 89.9% (77.3-95.7), HR (not calculable), log rank p = 0.015. The DDFS was as follows: IORT 3 events (95.1%, 85.5-98.4), EBRT 12 events (69.0%, 49.1-82.4), HR 0.23 (0.06-0.80), log rank p = 0.012. IORT during lumpectomy after neoadjuvant chemotherapy as a tumour bed boost appears to give results that are not worse than external beam radiotherapy boost. These data give further support to the inclusion of such patients in the TARGIT-B (boost) randomised trial that is testing whether IORT boost is superior to EBRT boost. (orig.)

    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

    Purpose: To assess the feasibility and toxicity of consolidative intensity-modulated whole abdominal radiotherapy (WAR) after surgery and chemotherapy in high-risk patients with advanced ovarian cancer. Methods and Materials: Ten patients with optimally debulked ovarian cancer International Federation of Gynecology and Obstetrics Stage IIIc were treated in a Phase I study with intensity-modulated WAR up to a total dose of 30 Gy in 1.5-Gy fractions as consolidation therapy after adjuvant carboplatin/taxane chemotherapy. Treatment was delivered using intensity-modulated radiotherapy in a step-and-shoot technique (n = 3) or a helical tomotherapy technique (n = 7). The planning target volume included the entire peritoneal cavity and the pelvic and para-aortal node regions. Organs at risk were kidneys, liver, heart, vertebral bodies, and pelvic bones. Results: Intensity-modulated WAR resulted in an excellent coverage of the planning target volume and an effective sparing of the organs at risk. The treatment was well tolerated, and no severe Grade 4 acute side effects occurred. Common Toxicity Criteria Grade III toxicities were as follows: diarrhea (n = 1), thrombocytopenia (n = 1), and leukopenia (n = 3). Radiotherapy could be completed by all the patients without any toxicity-related interruption. Median follow-up was 23 months, and 4 patients had tumor recurrence (intraperitoneal progression, n = 3; hepatic metastasis, n = 1). Small bowel obstruction caused by adhesions occurred in 3 patients. Conclusions: The results of this Phase I study showed for the first time, to our knowledge, the clinical feasibility of intensity-modulated whole abdominal radiotherapy, which could offer a new therapeutic option for consolidation treatment of advanced ovarian carcinoma after adjuvant chemotherapy in selected subgroups of patients. We initiated a Phase II study to further evaluate the toxicity of this intensive multimodal treatment.

    This paper presents the clinically confirmed benefits of combined chemotherapy-radiotherapy. They have been found in a small group of diseases that respond to chemotherapy alone. According to the author, only when a drug or drug combination has the ability to eradicate occult disease or substantially to reduce the size of objectively measurable disease is there likely to be an demonstrable benefit from its use in conjunction with radiotherapy. It is the author's belief that the immediate future lies in selecting drugs and patients in which a good chemotherapeutic response can be expected, avoiding drugs that seriously enhance radiation damage to normal tissues and keeping drug and radiation treatments far enough apart in time to minimize interactions

    The principal objective of combining chemotherapy with radiotherapy (XRT) for the treatment of advanced head and neck cancer is to improve the therapeutic ratio through the enhancement of local control and reduction of distant metastases without excessively enhancing normal tissue effects. Improved tumour control can result from sole additivity of either therapy or direct interactions between drug and radiation leading to increased tumour cell kill. Chemotherapy may sensitize the cells to radiation, interfere with repair of sublethal or potentially lethal radiation damage, induce cell synchrony, and reduce tumour mass leading to reoxygenation and decreased fraction of resistant hypoxic cells. Radiation may improve drug accessibility to tumour cells and reduce tumour volume leading to increased cell proliferation and chemosensitivity. If the enhanced effects of combined therapy are purely additive, then the two modalities can be administered either sequentially or concurrently with the same results. However, if the enhanced effects result from the direct interaction between drug and radiation, it is necessary that the two modalities be administered concurrently and in close temporal proximity. This review summarizes the results of clinical studies in which chemotherapy was administered concurrently during the course of radiotherapy for patients with previously untreated advanced squamous cell carcinoma in the head and neck

    The optimal treatment of advanced maxillary sinus cancer has been challenging for several decades. Intra-arterial chemotherapy (IAC) for head and neck cancer has been controversial. We have analyzed the long-term outcome of neoadjuvant IAC followed by radiation therapy (RT) and surgery. Twenty-seven patients with advanced maxillary sinus cancer were treated between 1989 and 2002. Five-fluorouracil (5-FU, 500 mg/m2) was infused intra-arterially, and followed by RT (total 50.4 Gy/28 fractions). A planned surgery was performed 3 to 4 weeks after completion of IAC and RT. At a median follow-up of 77 months (range, 12 to 169 months), the 5-year rates of overall survival in all patients were 63%. The 5-year rates of overall survival of stage T3/T4 patients were 70.0% and 58.8%, respectively. Seven of fourteen patients with disease recurrence had a local recurrence alone. The 5-year actuarial local control rates in patients with stage T3/T4, and in all patients were 20.0%, 32.3%, and 27.4%, respectively. Overall response rate after the completion of IAC and RT was 70.3%. During the follow-up, seven patients (25.9%) showed mild to moderate late complications. The tumor extent (i.e., the involvement of either orbit and/or base of skull) appeared to be related with local recurrence. Neoadjuvant IAC with 5-FU followed by RT and surgery may be effective to improve local tumor control in the patients with advanced maxillary sinus cancer. However, local failure was still the major cause of death. Further investigations are required to determine the optimal treatment schedule, radiotherapy techniques and chemotherapy regimens.

    Purpose: Breast conservation surgery (BCS) and radiotherapy (RT) following neoadjuvant chemotherapy (NCT) have been linked with high locoregional recurrence (LRR) rates and ipsilateral breast tumor recurrence (IBTR) rates. The purpose of this study was to analyze clinical outcomes in patients who exhibited LRR and IBTR after being treated by BCS and RT following NCT. Methods and Materials: In total, 251 breast cancer patients treated with BCS and RT following NCT between 2001 and 2006 were included. All patients had been shown to be clinically node-positive. Clinical stage at diagnosis (2003 AJCC) was II in 68% of patients and III in 32% of patients. Of those, 50%, 35%, and 15% of patients received anthracycline-based, taxane-based, and combined anthracycline-taxane NCT, respectively. All patients received RT. Results: During follow-up (median, 55 months), 26 (10%) patients had LRR, 19 of these patients had IBTR. Five-year actuarial rates of IBTR-free and LRR-free survival were 91% and 89%, respectively. In multivariate analyses, lack of hormone suppression therapy was found to increase both LRR and IBTR rates. Hazard ratios were 7.99 (p < 0.0001) and 4.22 (p = 0.004), respectively. Additionally, pathology stage N2 to N3 increased LRR rate (hazard ratio, 4.22; p = 0.004), and clinical AJCC stage III IBTR rate (hazard ratio, 9.05; p = 0.034). Achievement of pathological complete response and presence of multifocal tumors did not affect LRR or IBTR. Conclusions: In patients with locally advanced disease, who were clinically node-positive at presentation, BCS after NCT resulted in acceptably low rates of IBTR and LRR. Mastectomy should be considered as an option in patients who present with clinical stage III tumors or who are not treated with adjuvant hormone suppression therapy, because they exhibit high IBTR rates after NCT and BCS.

    Full text:Background: Tumour hypoxia is associated with disease progression and resistance to therapy. High grade cerebral gliomas have a poor outcome despite advancements in chemotherapy and radiotherapy. 18F-fluoromisonidazole (18F-FMISO) concentrates in hypoxic cells and is associated with tumour grade in gliomas. The aim of this study was to compare the patterns of uptake of 18F-FDG PET and 18F-FMISO PET post-surgery with MRI and areas of recurrence post-radiotherapy. Methods: Patients with high grade cerebral glioma were recruited into this prospective study. All patients had post-surgical, pre-radiotherapy 18F-FDG, 18F-FMISO and MRI scans, which were all repeated 4-6 weeks post-completion to radiotherapy. The patients were followed-up clinically three monthly and re-imaged if indicated. Results: Ten patients were enrolled in this study, mean age 62 years (range 55-69 years), who all had pre-radiotherapy scans performed. Seven patients had scans done pre- and post-radiotherapy, with 3 patients with only pre-therapy scans. Nine patients had significant FMISO uptake and 8 patients demonstrated abnormal FDG uptake. The areas of FMISO uptake on pre-radiotherapy scans correlated with the most abnormal areas of contrast-enhancement on pre-treatment MRI and areas of locally recurrent disease on post-treatment MRI in eight patients. Nine patients had locally recurrent disease on follow-up MRI. FMISO was more predictive of tumour recurrence compared to FDG. Conclusion: Post-surgical 18F-FMISO PET in patients with cerebral glioma is more predictive of areas of recurrent disease compared to 18F-FDG PET.

    Full Text Available Background: The role of breast cancer treatments in reducing recurrence and death has been established. However, the treatments side effects greatly impact on quality of life and little is known about the non-adherence rates. The purpose of this study was to determine the non-adherence rates to surgery, chemotherapy, radiotherapy and hormonal therapy, and factors that affect it in public hospitals in Malaysia. Methods: A multicentre cross-sectional study was conducted in six public hospitals involving all newly diagnosed breast cancer patients in 2012. Data were collected through medical record reviews and interview by using structured questionnaire. Non-adherence was categorized as any breast cancer patients refusing or discontinuing any treatment due to non-medical reasons. Univariable logistic regression and multiple logistic regressions were used for analysis. Results: A total of 340 breast cancer patients were included in the study. The proportion for non-adherence to surgery, chemotherapy, radiotherapy and hormonal therapy were 14%, 30.1%, 33.3% and 36.3% respectively. Factors associated with non-adherence to surgery were localities involving Kuala Lumpur (2 (OR: 3.41, Johor (OR: 8.38 and Kelantan (OR: 6.32, and those required mastectomy (OR: 5.66. No factors were found to be associated with non-adherence to chemotherapy, radiotherapy and hormonal therapy. These three treatment modalities were then combined as oncology therapy and the only independent factor associated with non-adherence to oncology therapy was Perak locality (OR: 1.42. Conclusion: Non-adherence to breast cancer treatments was high among breast cancer patients at public hospitals in Malaysia. Factors influencing non-adherence were locations and mastectomy implicating of socio-culture, body image issues, psychological disturbance and treatment navigation.

    Objective: to identify prognostic factors and evaluate the clinical outcome of patients with glioblastoma treated with surgery and radiotherapy combined or not with chemotherapy. Material and method: in this retrospective study, 48 patients with glioblastoma were treated between 1997 and 2007. All patients were classified according the recursive partitioning analysis (RPA) criteria. Results: the majority of patients were female, with 50 years of age or above. Performance status of 70 or greater were found in 70.8% of cases, and RPA classes V and VI prevailed. Seventy-two percent of patients were submitted to partial resection and 27.1% to total or subtotal resection. Chemotherapy was administered in 47.9% of patients and doses between 50 and 60 Gy were delivered in 72.9%. The median overall survival was 52 weeks. Conclusion: our data show an overall survival that approaches the related in others reports and were dependent of factors such as chemotherapy, dose of radiation and Karnofsky performance status.

    There are 4 modalities of combined radiotherapy and chemotherapy which include (1) concurrent radiotherapy and chemotherapy, (2) sequential use of radiotherapy and chemotherapy (pre-radiation chemotherapy), (3) pre-radiation chemotherapy followed by concurrent radiation and chemotherapy, and (4) alternating use of radiotherapy and chemotherapy based upon Looney's hypothesis. We studied concurrent use of radiotherapy and UFT by means of animal experimentation and clinical trials. The results obtained revealed that UFT was a most suitable agent together with 5-fluorouracil for concurrent application of radiotherapy and chemotherapy. Neo-adjuvant chemotherapy including pre-radiation chemotherapy was also studied in cases of maxillary sinus carcinoma and nasopharyngeal carcinoma. From the results, it seemed desirable to use cisplatin and bleomycin analogs sequentially in combined chemotherapy and radiotherapy. Neo-adjuvant chemotherapy should be studied successively to improve local tumor control rates and prevent distant metastases. For future perspectives, new trials of alternating radiotherapy and chemotherapy based upon Looney's hypothesis seem necessary. (author)

  4. Cancer occurring after radiotherapy and chemotherapy

    Radiotherapy and chemotherapy can effectively control cancer but can also cause new cancers to develop as long-term complications. Almost all types of cancer have been associated with radiotherapy. The breast, thyroid, and bone marrow are the organs most susceptible to radiation carcinogenesis. The bone marrow is also most frequently involved by chemotherapy and the leukemia risk is much higher than after radiotherapy. The combination of intensive radiotherapy and chemotherapy is particularly leukemogenic. The latent period between radiotherapy/chemotherapy and the appearance of a second primary cancer ranges from a few years to several decades. The risk for a second primary cancer following radiotherapy or chemotherapy emphasizes the need for life long follow-up of patients receiving such treatments. This is particularly the case in individuals with long life expectancy, for example, patients treated for childhood neoplasms. The benefits of radiotherapy and chemotherapy in oncology exceed the risks for second primary cancers. Efforts should be directed towards identifying those patients who will benefit from the treatments so that only they are exposed to the risk. 33 references

    Purpose: To examine the sites of pelvic recurrence in patients with rectal cancer previously untreated with radiotherapy to determine the relative frequency and location of recurrence within the pelvis. Methods and Materials: The records of patients with locally recurrent rectal cancer referred to three radiation oncology departments between 1984 and 1997 were reviewed. The data collected included the date and type of the initial resection and the pathologic findings. The site of recurrence within the pelvis, presence of metastasis, and date of recurrence were documented. Results: A total of 269 patients were included. Tumor had invaded through the muscularis in 74% and involved other organs in 9%. Fifty-two percent of patients were node positive at initial surgery. The median time to local recurrence from surgery was 18 months (range 15-20) and from local recurrence to death was 14 months (range 12-17). Both the initial tumor stage and the resection type influenced the recurrence location within the pelvis (p<0.01). T4 tumors comprised only 9% of initial T stage tumors but accounted for 38% of anterior central pelvic recurrences (p<0.01). All perineal recurrences occurred after abdominoperineal resection. The sites of recurrence within the pelvis were the posterior central pelvis (47%) and anastomotic (21%). Conclusion: If those patients with T4 tumors at presentation were excluded, 89% had local recurrence at, or posterior to, the anastomosis. Furthermore, if we exclude both patients who underwent abdominoperineal resection and those with T4 tumors at presentation, the rate increases to 93%. The rate of recurrence anteriorly (7%) does not justify routine radiation of the anterior pelvis beyond that required to adequately cover the anastomotic site

    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.

    Among head and neck cancers, cases affecting elderly people are increasing. Radical treatment is sometimes difficult in advanced cases of elderly patients. With progressive cancer, because radical surgery is often difficult, radiotherapy is chosen and may be used together with chemotherapy when overall status is good. However, according to the meta-analysis of Pignon et al., the chemoradiotherapy for elderly patients 71 years old or older, the hazard ratio becomes approximately 0.95, and there is little chemotherapy combined effect. In terms of 5-year survival rate, chemotherapy combined effect is -0.7%. Chemotherapy effect in elderly patients is not clear in past clinical trials. We examined 50 cases 75 years or older treated mainly by radiotherapy at Tokyo Medical Center between February, 2003 and August, 2011. In all, 21 of the 50 patients died, including four who died due to other cancers, while pneumonia accounted for five other deaths. These results suggested that various complications are often present and multiple primary cancers often occur in elderly people. With chemotherapy for elderly people, the effect of radiotherapy treatment and quality of life of the patients should be considered fully based on characteristics of elderly people, and a treatment plan devised accordingly. It is also necessary to undertake care after treatment. (author)

    Adjuvant chemotherapy is currently offered routinely, as standard, after radical resection for patients with rectal cancer receiving neo-adjuvant chemoradiation. However, the efficacy of adjuvant chemotherapy in patients with ypTis-2N0M0 has not been documented to the same extent, and the survival benefit remained controversial. The purpose of this work was to determine the role of chemotherapy in patients with ypTis-2N0M0 classification. Data were obtained from the Surveillance, Epidemiology, and End Results database ( n  = 4,217). A propensity score model was utilized to balance baseline covariates. Of the 4,217 included patients, 335 with ypTis-2N0M0 did not receive adjuvant chemotherapy. There were comparable cancer-specific survivals (CSS) between those undergoing adjuvant chemotherapy or not (log-rank test = 0.136, p  = .712) in the overall sample. After propensity score matching, the cancer-specific survival did not differ between the chemotherapy and observation groups (log-rank test = 0.089, p  = .765). Additionally, the Cox model did not demonstrate adjuvant chemotherapy as the prognostic factor, with hazard ratio = 0.95 (95% confidence interval 0.69-1.32) for CSS. Furthermore, the 10-year cumulative CSS was 78.7% and 79.4% between the chemotherapy and observation groups, indicating no significance, and no impact of adjuvant chemotherapy on survival was observed in different subgroups stratified by T stage, histological grade, histology, lymph nodes, and tumor size. Patients with ypTis-2N0 rectal cancer did not benefit from adjuvant chemotherapy after preoperative radiology and radical surgery in this cohort study. These results provided new insight into the routine use of adjuvant chemotherapy for patients with rectal cancer with completed neo-adjuvant radiotherapy and curative surgery. Inconsistent recommendations for patients with rectal cancer receiving neo-adjuvant chemoradiation are offered by clinical guidelines. Adjuvant

    Purpose: To evaluate the effects of delaying RT until after different durations of initial courses of CT for pts with node-positive breast cancer. Methods and Materials: From 7/86-4/93, the IBCSG enrolled 1475 eligible node-positive pre- and perimenopausal pts in Trial 6 and 1212 eligible node-positive postmenopausal pts in Trial 7. Pts in Trial 6 were randomized to receive one of four treatments: (1) CMF x 6 cycles (1 cycle=28 days; cyclophosphamide 100 mg/m{sup 2} orally days 1-14; methotrexate 40 mg/m{sup 2} iv. days 1 and 8; 5-fluorouracil 600 mg/m{sup 2} iv days 1 and 8); (2) CMF x 6 cycles followed by single cycles at months 9, 12 and 15; (3) CMF x 3 cycles; (4) CMF x 3 followed by single cycles at months 6, 9 and 12. Pts in Trial 7 were randomized to receive one of four treatments: (5) tamoxifen (TAM: 20 mg daily) plus CMF x 3 cycles, months 1,2,3; (6) TAM plus CMF x 3 plus single cycles of CMF at months 9, 12 and 15; (7) TAM alone for five yrs; (8) TAM plus single cycles of CMF at months 9, 12 and 15. The randomizations were stratified according to type of surgery; 434 pts in Trial 6 (29%) and 285 pts in Trial 7 (24%) had breast conserving surgery and are the subjects of this report. Pts were randomized to receive RT to the conserved breast AFTER completing the initial block of CT if assigned; i.e. month 7 for arms 1 and 2; month 4 for arms 3 and 4; month 4 for arms 5 and 6; month 1 for arms 7 and 8. 24% of pts in Trial 6 and 27% of pts in Trial 7 had four or more axillary lymph nodes involved. Possible prognostic factors including age, estrogen receptor status, nodal status and tumor size were balanced across randomized groups. Four-year actuarial total failure rates (failure at any site), risks of developing distant metastases (DM) (at any time during observation), and overall survival (OS) were estimated using the Kaplan-Meier method. To avoid potential bias due to competing causes of failure, only patients who could be followed for at least 4 years

    Surgery and/or radiotherapy have been the standard therapies for locally advanced squamous cell carcinoma of the head and neck region. Despite major improvement in these therapeutic techniques, the control rate in cases of advanced cancer remains poor. More recently, induction chemotherapy as initial treatment has been used in previously untreated squamous cell carcinoma of the head and neck. For the last 6 years at the Boston Veterans Administration (V.A.) Medical Center, initial induction chemotherapy followed by surgery and/or radiotherapy has been employed in the treatment of advanced head and neck cancer. The use of chemotherapy and radiotherapy has allowed the authors to monitor and correlate sequential response patterns produced by each modality of treatment. The authors have observed that responders to chemotherapy can be predicted to have further response to subsequent radiotherapy

    Metaplastic carcinoma of the breast is a rare tumor. The appearance of unexpected mesenchymal elements within the epithelial tumors is the squamous metaplasia. These tumors have a different clinical behaviour that classical breast carcinoma. We present a case of metaplastic mammary carcinoma with multiple relapses treated with a combination of chemotherapy and radiotherapy. The use of chemotherapy after local treatment has enhanced the relapse-free survival. The combined treatment modality seems to produce some benefit in the management of the local relapses of this neoplasms

    In 1981, the German Society of Pediatric Oncology initiated a multi-institutional study for the treatment of Ewing's sarcoma. The protocol (Cooperative Ewing's Sarcoma Study, CESS 81) consisted of four courses of a four-drug-regimen (VACA), each course taking nine weeks. Local therapy (radical surgery or resection plus irradiation or radiotherapy alone) was performed after the second course. The results of CESS 81 can be summarized as follows: VACA-chemotherapy is effective in controlling systemic disease. Initial tumor mass and response to initial chemotherapy are of major prognostic value for local control and survival. Permanent local control is a problem, especially in irradiated patients. The high local failure rate in irradiated patients in CESS 81 could be attributable to the following reasons: Late start of local therapy (after 18 weeks of chemotherapy), uneven distribution of prognostic parameters: Large tumors were more often irradiated than operated, protocol deviations in irradiated patients.

    Full Text Available Abstract Background Induction chemotherapy (ICT with docetaxel, cisplatin and fluorouracil (TPF followed by radiotherapy is an effective treatment option for unresectable locally advanced head and neck cancer. This phase I study was designed to investigate the safety and tolerability of a split-dose TPF ICT regimen prior to surgery for locally advanced resectable oral and oropharyngeal cancer. Methods Patients received TPF split on two dosages on day 1 and 8 per cycle for one or three 3-week cycles prior to surgery and postoperative radiotherapy or radiochemotherapy. Docetaxel was escalated in two dose levels, 40 mg/m2 (DL 0 and 30 mg/m2 (DL −1, plus 40 mg/m2 cisplatin and 2000 mg/m2 fluorouracil per week using a 3 +3 dose escalation algorithm. Results Eighteen patients were enrolled and were eligible for toxicity and response. A maximum tolerated dose of 30 mg/m2 docetaxel per week was reached. The most common grade 3+ adverse event was neutropenia during ICT in 10 patients. Surgery reached R0 resection in all cases. Nine patients (50% showed complete pathologic regression. Conclusions A split-dose regime of TPF prior to surgery is feasible, tolerated and merits additional investigation in a phase II study with a dose of 30 mg/m docetaxel per week.

    The metastasis of uterine leiomyosarcoma to the neck node has not been reported previously and the radiotherapy has been rarely used for the metastatic lesion of the other sites. We report a case of neck metastasis from a uterine leiomyosarcoma, which developed 10 months after surgery and postoperative pelvic radiotherapy. It also involved the parapharyngeal space, adjacent spine, and spinal canal. The metastatic neck mass was inoperable, and was treated by neck radiotherapy (6,000 cGy) and chemotherapy including taxol and carboplatin. The mass has regressed progressively to a nearly impalpable state. She has never developed spinal cord compression syndrome, and has maintained good swallowing for eight months since the neck radiotherapy and chemotherapy. Since the extensive metastatic neck mass showed good local response to high dose radiotherapy and chemotherapy, both treatments may be considered for an unresectable metastatic leiomyosarcoma

    Forty-three postmenopausal breast cancer patients with axillary lymph node metastasis were randomized to receive postoperative radiotherapy (45 Gy) or the combination of radiotherapy and 6 months of chemotherapy. Forty-three premenopausal patients had postoperative radiotherapy and were randomized to receive one of two different chemotherapy combinations. Pulmonary fibrosis was roentgenologically registered in approximately 70% of the total patient population six months after initiation of therapy. Addition of chemotherapy with doxorubicin and cyclophosphamide significantly increased the proportion of patients with pulmonary fibrosis compared with patients treated with radiotherapy only or radiotherapy combined with cyclophosphamide, methotrexate and 5-fluorouracil. Premenopausal patients tolerated the combination of radiotherapy and chemotherapy better than postmenopausal patients of whom approximately 30% did not tolerate 65% or more of prescribed total dose of chemotherapy.

    We report a case of intestinal lymphangiectasia secondary to radiotherapy and chemotherapy. The patient also had small bowel bacterial overgrowth and pancreatic insufficiency. Lymphatic ectasia as a histological feature has been described previously in association with postradiotherapy malabsorption, but radiation-induced lymphangiectasia producing clinical manifestations has hitherto not been reported. Replacement of dietary long-chain fats with medium-chain triglycerides, pancreatic enzyme supplements, and a short course of oxytetracycline, resulted in dramatic clinical improvement. The possibility of intestinal lymphangiectasia should be borne in mind in patients with postradiotherapy malabsorption. A low serum albumin and lymphocyte count should draw attention to this possibility

    From 1975 to 1983, a total of 51 cases of esophageal cancer with T2 ∼ T3 in TNM classification, were treated by radiotherapy alone or combined chemotherapy. All 51 patients received total dose of 60 ∼ 70 GY for 6 ∼ 8 weeks and 20 out of 51 were treated by radiotherapy plus chemotherapy (5FU or UFT and/or bleomycin or pepleomycin). The 2-year-survival rate was slightly better in patients treated by radiotherapy plus chemotherapy than in patients treated by radiotherapy alone, but this difference was not significant. (author)

    BACKGROUND: Combined modality treatment consisting of chemotherapy followed by localised radiotherapy is the standard treatment for patients with early stage Hodgkin lymphoma (HL). However, due to long- term adverse effects such as secondary malignancies the role of radiotherapy has been questioned...... recently and some clinical study groups advocate chemotherapy only for this indication. OBJECTIVES: To assess the effects of chemotherapy alone compared to chemotherapy plus radiotherapy in adults with early stage HL . SEARCH METHODS: For the or i ginal version of this review, we searched MEDLINE, Embase......-related mortality (RR 0.99; 95% CI 0.14 to 6.90; P = 0.99; low-quality evidence), there is no evidence for a difference between the use of chemotherapy alone and chemotherapy plus radiotherapy. CRR rate was not reported. AUTHORS' CONCLUSIONS: This systematic review compared the effects of chemotherapy alone...

    A Patterns of Care Study examined the records of patients with thoracic esophageal cancer treated with radiotherapy and surgery in 1995 through 1997. Thirty-one percent of patients received preoperative radiotherapy; 61% of these received chemotherapy. Sixty six percent of patients received postoperative radiotherapy. Significant variables for overall survival in multivariate analysis include presence of macroscopic residual tumors (risk ratio=2.66), sex female (0.49), photon energy higher than 4 MV (0.50), Karnofsky performance status greater than 70 (0.55) and the use of chemotherapy (1.64). The value of preoperative concurrent chemotherapy and radiotherapy should be tested in a randomized trial. (author)

    Recently, by applying multidrug therapy using cisplatin and bleomycin to the treatment of head and neck cancer, the response rate of chemotherapy has been markedly increased and thus, chemotherapy has taken an important part in the treatment of head and neck cancer. In this paper a clinical application of chemotherapy in combination with radiotherapy was evaluated from the point of the cure rate and also preservation of the structures and the functions of the head and neck region. In order to test the advantage or usefulness of initial chemotherapy followed by radiotherapy (= pre-radiation chemotherapy), the experimental study on combination of chemotherapy and radiotherapy was designed by using ICR mice and Ehrlich solid carcinoma. Cisplatin and peplomycin, a newly developed derivative of bleomycin, were used as chemotherapeutic agents. Tumor growth delay rate was chosen as a parameter to indicate the effectiveness. Results obtained are as follows. 1. Combination chemotherapy of cisplatin and peplomycin was more effective than each single agent on Ehrlich solid carcinoma. Synergistic effect was obtained by higher dose. So, the combination of cisplatin and peplomycin was proved to be eligible for pre-radiation chemotherapy. 2. Synergistic effect of chemotherapy and radiotherapy was observed when chemotherapy was used prior to radiotherapy on Ehrlich solid carcinoma. 3. Even their additional effect was not recognized when radiotherapy preceded to chemotherapy on Ehrlich solid carcinoma. 4. No severe toxic effect was seen in the mice. The experimental results made it clear that pre-radiation chemotherapy is beneficial to the treatment of head and neck cancer. (author)

    Purpose: In 1996, a multicenter randomized study was initiated that compared sequential vs. concurrent adjuvant chemotherapy (CT) with radiation therapy (RT) after breast-conserving surgery (ARCOSEIN study). After a median follow-up of 6.7 years (range, 4.3-9 years), we decided to prospectively evaluate the late effects of these 2 strategies. Methods and Materials: A total of 297 patients from the 5 larger participating institutions were asked to report for a follow-up examination. Seventy-two percent (214 patients) were eligible for evaluation of late toxicity. After breast-conserving surgery, patients were treated either with sequential treatment with CT first followed by RT (Arm A) or CT administered concurrently with RT (Arm B). In all patients, CT regimen consisted of mitoxantrone (12 mg/m 2 ), 5-FU (500 mg/m 2 ), and cyclophosphamide (500 mg/m 2 ), 6 cycles (Day 1 to Day 21). Conventional RT was delivered to the whole breast by administration of a 2 Gy per fraction protocol to a total dose of 50 Gy (± boost to the primary tumor bed). The assessment of toxicity was blinded to treatment and was graded by the radiation oncologist, according to the LENT/SOMA scale. Skin pigmentation was also evaluated according to a personal 5-points scoring system (excellent, good, moderate, poor, very poor). Results: Among the 214 evaluable patients, 107 were treated in each arm. The 2 populations were homogeneous for patient, tumor, and treatment characteristics. Subcutaneous fibrosis (SF), telangectasia (T), skin pigmentation (SP), and breast atrophy (BA) were significantly increased in Arm B. No statistical difference was observed between the 2 arms of the study concerning Grade 2 or higher pain, breast edema, or lymphedema. No deaths were caused by late toxicity. Conclusion: After breast-conserving surgery, the concurrent use of CT with RT is significantly associated with an increase incidence of Grade 2 or greater late side effects

    Late effects of adjuvant treatment on perceived health and quality of life were assessed through a questionnaire mailed to 448 premenopausal and postmenopausal breast cancer patients, free from recurrence 2-10 years after primary therapy. The patients had been randomised to postoperative radiotherapy or adjuvant chemotherapy as adjuncts to primary surgery. The differences between the two treatments were generally small. However, the radiotherapy patients had significantly greater problems with decreased stamina, symptoms related to the operation scar and anxiety. The chemotherapy patients had significantly more problems with smell aversion. Activity level inside and outside the home, anxiousness and depressive symptoms were similar in both groups. The chemotherapy patients scored their overall quality of life higher than the radiotherapy patients. (author)

    To see the relationship between the response to chemotherapy and the final outcome of neoadjuvant chemotherapy and radiotherapy in patients with locally advanced hypopharyngeal cancer. A retrospective analysis was done for thirty-two patients with locally advanced hypopharyngeal cancer treated in the Seoul National University Hospital with neoadjuvant chemotherapy and radiotherapy from August 1979 to July 1997. The patients were treated with Co-60 teletherapy unit or 4MV or 6MV photon beam produced by linear accelerator. Daily fractionation was 1.75 to 2 Gy, delivered five times a week. Total dose ranged from 60.8 Gy to 73.8 Gy. Twenty-nine patients received continuous infusion of cisplatin and 5-FU. Other patients were treated with cisplatin combined with bleomycin or vinblastin. Twenty-four (75%) patients received all three prescribed cycles of chemotherapy delivered three weeks apart. Six patients received two cycles, and two patients received only one cycle. The overall 2-year and 5-year survival rates are 65.6% and 43.0, respectively. 5-year local control rate is 34%. Organ preservation for more than five years is achieved in 12 patients (38%). After neoadjuvant chemotherapy, 24 patients achieved more than partial remission (PR); the response rate was 75% (24/32). Five patients had complete remission (CR), 19 patients PR, and 8 patients no response (NR). Among the 19 patients who had PR to chemotherapy, 8 patients achieved CR after radiotherapy. Among the 8 non-responders to chemotherapy, 2 patients achieved CR, and 6 patients achieved PR after radiotherapy, There was no non-responder after radiotherapy. The overall survival rates were 60% for CR to chemotherapy group, 35.1 % for PR to chemotherapy group, and 50% for NR to chemotherapy group. respectively (p=0.93). There were significant difference in five-year overall survival rates between the patients with CR and PR after neoadjuvant chemotherapy and radiotherapy (73.3% vs. 14.7%, p< 0.01). The prognostic

    Abstract This study explored which kinds of cancer are related to a higher incidence of subsequent myelodysplastic syndrome (MDS) after radiotherapy (RT) and chemotherapy (CT). We performed a nested case–control study by using data from the Taiwanese National Health Insurance (NHI) system. The case group included cancer patients who developed MDS. For the control group, 4 cancer patients without MDS were frequency-matched with each MDS case by age, sex, year of cancer diagnosis, and MDS index year. A multivariable logistic regression analysis was conducted, and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated. Overall, cancer patients who received RT or CT exhibited secondary MDS more frequently than did those who did not (RT: OR = 1.53; 95% CI = 1.33–1.77; CT: OR = 1.51; 95% CI = 1.25–1.82). Analysis by cancer site showed that RT increased the risk of MDS for patients with stomach, colorectal, liver, breast, endometrial, prostate, and kidney cancers. By contrast, CT was more likely to increase the risk of MDS for patients with lung, endometrial, and cervical cancers. Further analysis revealed that RT and CT seemed to have a positive interaction. The major limitation of this study was the lack of certain essential data in the NHI Research Database, such as data regarding cancer stage and treatment dose details. This population-based nested case–control study determined that RT and CT predisposed patients in Taiwan to the development of MDS. This effect was more prominent when both modalities were used.

    Background: The timing of surgery and postoperative radiotherapy - especially if combined with chemotherapy - has been a subject of interest over the past years. Methods: This analysis was based on a literature review of mostly retrospective publications. Data concerning the interval between surgery and radiotherapy were correlated with the locoregional control, incidence of distant metastases and prognosis of breast cancer, lung carcinoma, and head and neck carcinomas. Results and Conclusions: The reviewed data did not show a clear relationship of the time interval between surgery and start of radiotherapy and locoregional control. However, evaluation of the data was difficult, because in most publications, retrospective analyses were performed and other prognostically more relevant parameters may influence locoregional control stronger than the time interval. In patients with head and neck carcinomas, there is a negative effect of time interval between surgery and radiotherapy on local control if unfavorable factors exist, i.e., close surgical margins, unfavorable pathohistological parameters and low radiation dose. In patients with breast cancer who do not receive chemotherapy, there are inconsistent reports in the literature. If additional chemotherapy is necessary, the sequence surgery, chemotherapy and radiotherapy seems adequate. Although some data suggest that delaying the initiation of radiotherapy due to chemotherapy may increase the risk of local recurrences, there may, on the other hand, be an increased likelihood of systemic metastases, if radiotherapy is applied before chemotherapy. Concerning lung cancer, only one retrospective analysis exists suggesting a better survival of patients with an interval of more than 36 days between surgery and radiotherapy as compared to patients with a shorter interval.

    Hidradenocarcinoma is a rare carcinoma of high malignant potential. It most metastasizes to regional lymph nodes and distant viscera. We report a case of 52-year-old woman who presented with an invasive hidradenocarcinoma of the finger, treated with surgical excision. The patient presented with skin and lymph node metastases four years after, treated by chemotherapy. Hidradenocarcinoma is an aggressive tumor. It seems important to use adjuvant therapies particularly for recurrent and metastatic forms.

    Purpose: To evaluate the local control rates, survival rates, and patterns of failure for esophageal cancer patients receiving preoperative concurrent chemotherapy and hyperfractionated radiotherapy followed by esophagectomy. Methods and Materials: From May 1993 through January 1997, 94 patients with resectable esophageal cancers received continuous hyperfractionated radiation (4,800 cGy/40 fx/4 weeks), with concurrent FP chemotherapy (5-FU 1 g/m 2 /day, days 2-6, 30-34, CDDP 60 mg/m 2 /day, days 1, 29) followed by esophagectomy 3-4 weeks later. If there was evidence of disease progression on preoperative re-evaluation work-up, or if the patient refused surgery, definitive chemoradiotherapy was delivered. Minimum follow-up time was 2 years. Results: All patients successfully completed preoperative treatment and were then followed until death. Fifty-three patients received surgical resection, and another 30 were treated with definitive chemoradiotherapy. Eleven patients did not receive further treatment. Among 91 patients who received clinical reevaluation, we observed 35 having clinical complete response (CR) (38.5%). Pathologic CR rate was 49% (26 patients). Overall survival rate was 59.8% at 2 years and 40.3% at 5 years. Median survival time was 32 months. In 83 patients who were treated with surgery or definitive chemoradiotherapy, the esophagectomy group showed significantly higher survival, disease-free survival, and local disease-free survival rates than those in the definitive chemoradiation group. Conclusion: Preoperative chemoradiotherapy in this trial showed improved clinical and pathologic tumor response and survival when compared to historical results. Patients who underwent esophagectomy following chemoradiation showed decreased local recurrence and improved survival and disease-free survival rates compared to the definitive chemoradiation group

    There are two purposes of using combined chemotherapy and radiotherapy in the treatment of cancers. One is to suppress distant metastasis, especially micrometastasis; the other is to improve localized control. As a trial of the utility of the former, systemic chemotherapy with CDDP and 5 FU was given successively with radiotherapy to treat nasopharyngeal cancer. The survival rate was significantly improved compared with historical control cases. The main reason for this effectiveness was the improvement of localized control. The suppression of distant metastasis is the subject of future research. As a trial of the utility of the latter, a super-selective intraarterial chemotherapy with CBDCA combined with radiotherapy was used to head and neck localized progressive cancers. The control of localized cancer was remarkably effective. This treatment is considered to be especially suitable for locally advanced tongue cancer and cancer of the root of the tongue. (author)

    Objective: To investigate the change of breast cancer patients' electrocardiogram during combined radiotherapy and chemotherapy or chemotherapy alone for the sake of predicting the cardiotoxicity of combined radiotherapy and chemotherapy. Methods: From January, 1998 to June, 2004, 47 postoperative breast cancer patients were enrolled. Among them 29 patients received chemotherapy combined with radiotherapy (combinative group), and 18 patients received chemotherapy alone (non combinative group). The changes of electrocardiogram were observed and correlation factors were analyzed. Results: Abnormal electrocardiograms were noted in 11 (37.9%) and 2 patients (11.1%) of the combinative group and the non-combinative group respectively(z=-1.977, P=0.048). In the combinative group, heart events were significantly increased in patients above 60 years old (z=- 2.094 P=0.036). The changes of electrocardiogram were not significantly correlative with hypertension history, tumor site, dose of radiotherapy or chemotherapeutic drugs. But the incidence of abnormal electrocardiogram was higher in patients with a hypertension history than in those without it (54.5% vs 27.8%). Conclusion: The abnormalities of electrocardiogram were are more frequent in patients treated with both radiotherapy combined with chemotherapy. Our results suggest that breast cancer patients should be regularly reexamined with electrocardiography during therapy, especially whose age was those have a hypertension history and above 60 years old.

  19. Second neoplasms following radiotherapy or chemotherapy for cancer

    While radiotherapy and antineoplastic chemotherapy often control malignancies they may, paradoxically, cause new cancers to develop as long-term complications. Although almost any type of neoplasm can occur, radiation-induced malignancies are most likely to affect the myelopoietic tissues and the thyroid gland. The former tissues are also most frequently involved by chemotherapy. The combination of intensive radiotherapy and intensive chemotherapy is particularly leukemogenic. Acute myeloid leukemia has occurred with increased frequency following treatment of Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, ovarian cancer, polycythemia vera, carcinoma of the thyroid gland, and carcinoma of the breast. Radiation-induced malignancies usually occur in the field of irradiation. Tumors developing in an irradiated field include a substantial number of soft tissue sarcomas or osteosarcomas. There is a 20-fold increase of second cancers following treatment of childhood malignancies, mostly sarcomas of bone and soft tissues, but including leukemia, and carcinomas of the thyroid gland, skin, and breast. The latent period between radiotherapy and the appearance of a second cancer ranges from 2 years to several decades, often being 10-15 years. With chemotherapy the mean latent period is shorter, approximately 4 years. The mechanism of oncogenesis by radiotherapy or chemotherapy is poorly understood and probably involves a complex interplay of somatic mutation, co-oncogenic effects, depression of host immunity, stimulation of cellular proliferation, and genetic susceptibility

    Fifty-six patients with carcinoma of the lung treated with radiotherapy alone or combination of chemotherapy were reviewed. Radiation was given with a 10MV photon beam by a linear accelerator. A fraction dose of 2Gy (200 rad) was given routinely 5 times a week. Combined durgs consist of 5FU or FT-207 in monochemotherapy and METT, MFC, or METVFC in combination chemotherapy. 5 year survival rate of all patients was 3.8%. As for the stage classification, 5 year survival rate is 30% in Stage I and II cancer, but there was no 3 year survivor in Stage III cancer and 2 year survivor in Stage IV cancer. As for the cell types, cases of adenocarcinoma had worse prognosis than them of squamous cell carcinoma and small cell carcinoma. The prognosis of patients treated with combination of radiotherapy and chemotherapy was similar to that of patients treated with radiotherapy alone. These results suggest that combined chemotherapy did not influence tumor control. Some discussion on the treatment modality of chemotherapy are made, emphasizing untoward effect of chemotherapy on immunopotency. (author)

    Purpose: To determine the effects of different sequences of CT and RT following CS for pts with clinical Stage I or II breast carcinoma. Methods and Materials: From 6/84-12/92, 244 pts were randomized following CS to receive CT (4 cycles of CAMFP at 3-wk intervals) either before or after RT. Median pt age was 45 yrs (range, 20-68). 164 pts were pre-, 18 pts peri-, and 62 pts were postmenopausal. 209 pts were node-positive (61 had 4 or more positive nodes); after 6/88, 35 selected node-negative pts were also included. 45 Gy was prescribed to the entire breast, followed by a boost of 16 Gy; nodal RT was optional. The medians ( and ranges) of the surgery-radiotherapy interval (SRI) according to assigned arm were: RT-first, 36 days (14-234); CT-first, 126 days (98-185). Drug doses were based on ideal body weight. Doses (per square meter) and schedule were: methotrexate, 200 mg, d.1 and 15; leucovorin, 10 mg, q6H x 12, start d.2 and 16; 5-fluorouracil, 500 mg, d.1; cyclophosphamide, 500 mg, d.1; prednisone, 40 mg/day x 5d, start d.1; and doxorubicin, 45 mg, d.3. All except leucovorin and prednisone were given by IV bolus. Dose reductions were based on the granulocyte nadir from the previous cycle, with an attempt to reescalate doses in subsequent cycles. Tamoxifen 10 mg BID was prescribed to postmenopausal pts with ER+ tumors following both RT and CT. 4 pts were ineligible due to prior malignancies, 2 pts on the RT-first arm refused their assigned sequence and received CT first, 2 pts on the RT-first arm and 1 pt on the CT-first arm refused to start or complete CT, 1 pt on the CT-arm underwent elective mastectomy prior to starting RT, and 1 pt on each arm received nonprotocol CT. Possible prognostic factors including age, menopausal status, ERP status, nodal status, and lymphatic vessel invasion were distributed nearly uniformly between the 2 arms. There was an excess of pts with EIC-positive tumors on the RT-first arm (25%) compared to the CT-first arm (11%) (p-bar=0

    The significance of combination of chemotherapy in radiotherapy for esophageal cancer was evaluated in 32 patients. They were irradiated routinely in 5 times a weeks with a fraction dose of 200 rad by 10MV-X-ray linear accelerator. Combined drugs consist of Bleomycin or Pepleomycin in two-third and 5FU or FT-207 in one-third. There was statistically no significance between the results of radiation alone and combined chemotherapy, and the improvement of survival rate could not be obtained by combining chemotherapy. Some discussion on the causes of this unimprovement were made. (author)

    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

    The aim of this study was to identify clinical variables that may predict the need for adjuvant radiotherapy after neoadjuvant chemotherapy (NACT) and radical surgery in locally advanced cervical cancer patients. A retrospective series of cervical cancer patients with International Federation of Gynecology and Obstetrics (FIGO) stages IB2-IIB treated with NACT followed by radical surgery was analyzed. Clinical predictors of persistence of intermediate- and/or high-risk factors at final pathological analysis were investigated. Statistical analysis was performed using univariate and multivariate analysis and using a model based on artificial intelligence known as artificial neuronal network (ANN) analysis. Overall, 101 patients were available for the analyses. Fifty-two (51 %) patients were considered at high risk secondary to parametrial, resection margin and/or lymph node involvement. When disease was confined to the cervix, four (4 %) patients were considered at intermediate risk. At univariate analysis, FIGO grade 3, stage IIB disease at diagnosis and the presence of enlarged nodes before NACT predicted the presence of intermediate- and/or high-risk factors at final pathological analysis. At multivariate analysis, only FIGO grade 3 and tumor diameter maintained statistical significance. The specificity of ANN models in evaluating predictive variables was slightly superior to conventional multivariable models. FIGO grade, stage, tumor diameter, and histology are associated with persistence of pathological intermediate- and/or high-risk factors after NACT and radical surgery. This information is useful in counseling patients at the time of treatment planning with regard to the probability of being subjected to pelvic radiotherapy after completion of the initially planned treatment.

    We report a case of remnant pancreatic cancer after pancreatoduodenectomy that was successfully treated using chemotherapy and carbon-ion radiotherapy. A 68-year-old woman received SSPPD for pancreatic head cancer. Gemcitabine (GEM) was administered for a year as postoperative chemotherapy. One year 8 months after surgery, abdominal CT showed a 20 mm solid mass in the stump of the remnant pancreas and dilation of the distal pancreatic duct. FDG-PET revealed a solitary tumor without any recurrence. We diagnosed the patient with a solitary recurrence of pancreatic cancer. Chemotherapy (GEM) and carbon-ion radiotherapy were performed. After treatment, the lesion was not detected on CT or FDG-PET. Chemotherapy (GEM) and carbon-ion radiotherapy for locally advanced pancreatic cancer seems to be effective and there might result in a survival benefit. (author)

    Apart from densely ionising radiations, radiotherapy and chemotherapy after partial synchronisation of the cell cycle are, at the moment, the only way to improve the efficiency of a treatment of malignant tumours. The new principle is based on the finding that tumour cells are more sensitive to radiation or chemotherapy in a certain metabolic situation. Partial synchronisation of the cell cycle makes it possible to enrich tumour cells in a certain metabolic state. In order to show the efficiency of such a measure, several methods can be used. Recently, impulse cytophotometry has been replacing these methods, since it permits a quick, simple, and individual control of the synchronisation effect. However, there has not been any clinical experiment yet to prove that tumour cells show a maximum sensitivity to radio- and chemotherapy in the G 2 -M-phase. This is why a number of patients with malignant tumours which could not be operated or treated with the usual radiotherapy or polychemotherapy were treated according to this new therapeutic principle. The results obtained in 233 cases encourage the specialists to continue the experiments. The indication of a treatment after partial synchronisation of the cell cycle should be based on the tumour spread as documented according to the TNM-system. Only when these guidelines are followed will it be possible to explain the problems still unsolved in the principle of radiotherapy and chemotherapy after partial synchronisation of the cell cycle and to carry out radio- and chemotherapy with improved efficiency in the future.

    At the Gynaecological Department of Radiumhemmet a noninvasive procedure in the diagnosis of ovarian masses has been developed during the 1950's. A fine-needle aspiration biopsy instrument developed and evaluated has been extensively utilized during the last 20 years for the diagnosis of ovarian masses. Fine-needle aspiration biopsy gave the opportunity to apply the philosophy of Hans-Ludvig Kottmeier who already declared in 1961 that aggressive and extensive surgery is valid for mucinous cancer but not for serous and endometrioid neoplasms fixed to surrounding tissues. This was the rational behind the Radiumhemmet policy where preoperative fine-needle aspiration biopsy diagnosis made it possible to use pre-operative chemotherapy and radiotherapy in patients with loco-regional disease

    In clinical application of radiation therapy combined with chemotherapy, it is important to gain the maximal therapeutic benefit. At present we have no agents that improve the therapeutic ratio by enhancing the effect of radiation on the tumor cell selectively. Therefore, it is necessary to use combining some or all of following procedures: (1) the intraarterial infusion of the agents, (2) the selective localization by reason of the biological affinity of the agents, (3) the surgical removal of the non-sensitized tumor residue and (4) the selective sensitization of the tumor due to its shorter cell cycle.

    The present paper discusses some of the methodological issues which can confound the interpretation of clinical trials of combined modality treatment. It reviews some of the larger randomized trials which have evaluated combined modality treatment in cancers of the head and neck, lung, gastrointestinal tract and bladder. It concludes that adequate trials have yet to be performed in many of thses sites, but that at present, evidence for long-term benefit from adjunctivechemotherapy is meagre. Finally, it suggests some possible mechanisms which might heve limited the benefit of chemotherapy when added to radiation treatment. (Author). 87 refs.; 4 figs.; 4 tabs

    At the Radiotherapeutic Department of the Faculty of Medicine in Istanbul, 35 masculine patients with microcellular bronchial carcinoma, limited disease, were treated for two years, i.e. between 1980 and 1981, with a combination of radiotherapy and chemotherapy. Nine out of these patients are tumor-free after at least 46 months, i.e. about four years. This corresponds to a tumor-free survival rate of 25.7%. (orig.) [de

    The purpose of this preliminary study was to determine the incidence of second malignancies after combined-modality therapy for adults with Hodgkin disease and relate it to the details of initial treatment. We retrospectively studied 286 patients ranging in age from 16 to 88 years with stage I or II Hodgkin disease who were treated between 1980 and 1995 with chemotherapy followed 3 to 4 weeks later by radiotherapy. Patients received a median of three cycles of induction chemotherapy. Mitoxantrone, vincristine, vinblastine, and prednisone was used in 161 cases, mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) in 67 cases, Adriamycin, bleomycin, vinblastine, and dacarbazine in 19 cases, lomustine, vinblastine, procarbazine, and prednisone/doxorubicin, bleomycin, dacarbazine, and lomustine in 18 cases, and other chemotherapeutic regimens in the remaining 21 cases. The median radiotherapy dose was 40 Gy given in 20 daily 2-Gy fractions. Median follow-up of surviving patients was 7.4 years. There were 2,230 person-years of observation. Significantly increased relative risks (RR) were observed for acute myeloid leukemia (RR, 69.3; 95% CI, 14.3-202.6) and melanoma (RR, 7.3; 95% CI, 1.5-21.3). The 5-, 10-, and 15-year actuarial risks of acute myeloid leukemia were 0.8%, 1.3%, and 1.3%, respectively. Patients treated with MOPP had the highest 15-year actuarial risk of leukemia (1.6%). The 5-, 10-, and 15-year actuarial risks of solid tumors were 1.9%, 9.3%, and 16.8%, respectively. Consolidative radiotherapy to both sides of the diaphragm resulted in a trend toward an increased risk of solid tumors relative to radiotherapy to only one side of the diaphragm (p = 0.08). In an effort to reduce the risk of second malignancies, we have stopped using the alkylating agents nitrogen mustard and procarbazine and elective paraaortic and splenic radiotherapy after chemotherapy.

    Current standard for most of the locally advanced rectal cancers is preoperative chemoradiotherapy, and, variably per institution, postoperative adjuvant chemotherapy. Short-course preoperative radiation with delayed surgery has been shown to induce tumour down-staging in both randomized and observational studies. The concept of neo-adjuvant chemotherapy has been proven successful in gastric cancer, hepatic metastases from colorectal cancer and is currently tested in primary colon cancer. Patients with rectal cancer with high risk features for local or systemic failure on magnetic resonance imaging are randomized to either a standard arm or an experimental arm. The standard arm consists of chemoradiation (1.8 Gy x 25 or 2 Gy x 25 with capecitabine) preoperatively, followed by selective postoperative adjuvant chemotherapy. Postoperative chemotherapy is optional and may be omitted by participating institutions. The experimental arm includes short-course radiotherapy (5 Gy x 5) followed by full-dose chemotherapy (capecitabine and oxaliplatin) in 6 cycles before surgery. In the experimental arm, no postoperative chemotherapy is prescribed. Surgery is performed according to TME principles in both study arms. The hypothesis is that short-course radiotherapy with neo-adjuvant chemotherapy increases disease-free and overall survival without compromising local control. Primary end-point is disease-free survival at 3 years. Secondary endpoints include overall survival, local control, toxicity profile, and treatment completion rate, rate of pathological complete response and microscopically radical resection, and quality of life. Following the advances in rectal cancer management, increased focus on survival rather than only on local control is now justified. In an experimental arm, short-course radiotherapy is combined with full-dose chemotherapy preoperatively, an alternative that offers advantages compared to concomitant chemoradiotherapy with or without postoperative

    The high 10 year life expectancy and the minimization of risk to all types of vascular accidents and evolution towards myelofibrosis argue strongly in favour of myelosuppression by /sup 32/P as the therapy of choice for polycythemia vera. The long term risk of leukemia which is the main argument against this form of treatment can be assessed for the alternative (chemotherapy with Busulphan or Melphelan, combination of hydroxyurea with phlebotomies) only if there is a sufficient follow-up time (at least 10 years) and if the patients followed were treated with only one therapeutic modality during the whole period. For this reason only cooperative protocols designed for long periods of application and follow-up can resolve the questions posed. Further, it is essential in such studies that the therapeutic results are assessed not only in terms of the survival of the patients but also in terms of the quality of their lives following the various forms of treatment.

    We evaluated the usefulness of simultaneous intra-arterial chemotherapy and radiotherapy for oropharyngeal cancer without neck metastasis. Fifty eight cases without neck metastasis out of previously untreated 117 patients with oropharyngeal cancer treated at National Kyushu Cancer Center from 1972 to 1995 were examined. Seventeen patients were in T1, 27 in T2, 10 in T3, 4 in T4. Fourteen patients of 58 patients were treated by simultaneous intra-arterial chemotherapy and radiation therapy. The 5-year survival rate by Kaplan-Meier method for intra-arterial infusion group and non intra-arterial infusion group were 86% and 71%, respectively. Thirty one patients were treated with irradiation without surgery. In 31 cases without surgery, the 5-year survival rate for intra-arterial infusion group (13 cases) was 85%, while that for non intra-arterial infusion group (18 cases) was 60%, and the local control rate for intra-arterial infusion group is 92%, while that for non intra-arterial infusion group was 56%. Simultaneous intra-arterial chemotherapy and radiotherapy for oropharyngeal cancer without neck metastasis is useful to improve the prognosis with preserving the function. (author)

  18. Mutational effects of radiotherapy and chemotherapy

    Morley, A.A.

    In studies of mutagenesis, lymphocytes have been used as nucleated mammalian cells rather than as specific immune cells. Nevertheless, there are good data that both chemotherapy and radiation result in long-term effects on the immune system both in experimental animals and in humans, and produce long-term qualitative and/or quantitative changes in various immune populations. The peripheral blood lymphocyte, however, may well be quite a good model for the hemopoietic stem cell, since both cells are normally G/sub o/ and both have very extensive proliferative capacity. Thus individual circulating human T lymphocytes are able to give rise to between 10/sup 8/ and 10/sup 32/ descendants, and individual murine stem cells are capable of completely restoring hemopoiesis, implying that they are able to give rise to at least 10/sup 11/-10/sup 12/ descendants. If mutations occur in hemopoietic stem cells as they do in T lymphocytes, then one could readily envisage how late effects such as carcinogenesis and proliferative failure might result

    Though the planned combined use of surgery and radiation has been shown to be beneficial for other tumors, the authors feel that the present evidence is far from persuasive in demonstrating a definite superiority of combined therapy over surgery or radiation alone for advanced laryngeal tumors. The actuarial or disease-free survival rates for patients treated with combined therapy have not been significantly increased over those obtained with a single modality in any randomized, well-controlled study, although the trend is toward improved local regional control. Many of the retrospective studies are probably flawed by selection bias; the patients selected for combined treatment generally have more advanced cancers and represent a worse prognostic group. It is clear from this review that the positive value of irradiation for advanced transglottic and supraglottic tumors needs to be documented by a controlled study that compares surgery alone with salvage radiation at time of recurrence to surgery plus adjuvant radiation. The authors feel that such a study is needed to put to rest the present controversy before they can advocate a course of treatment that is expensive, time-consuming, and difficult for the patients to tolerate owing to severe acute side effects and potentially morbid late effects (xerostomia, necrosis) that can greatly lessen the quality of life for these patients

    Complications of modern surgery for radiotherapy skin damage reviewed in 28 patients who had 42 operations. Thin split-thickness skin grafts for ulcer treatment had a 100 percent complication rate, defined as the need for further surgery. Local flaps, whether delayed or not, also had a high rate of complications. Myocutaneous flaps for ulcers had a 43 percent complication rate, with viable flaps lifting off radiated wound beds. Only myocutaneous flaps for breast reconstruction and omental flaps with skin grafts and Marlex mesh had no complications. The deeper tissue penetration of modern radiotherapy techniques may make skin grafts and flaps less useful. In reconstruction of radiation ulcers, omental flaps and myocutaneous flaps are especially useful, particularly if the radiation damage can be fully excised. The pull of gravity appears detrimental to myocutaneous flap healing and, if possible, should be avoided by flap design

Seven hundred and fifteen were male and three hundred and twenty-seven were female. Ora cancer was affected more male than female patients, with mean age of 582 years old. The tongue was the most common anatomic localization of oral cancer. In tongue, the use of external radiotherapy y combined with brachytherapy and brachytherapy isolated presented better results than chemotherapy combined with external radiotherapy. In buccal mucosa, there was not differences in the treatment's results using external radiotherapy and combined chemotherapy and external radiotherapy. In tongue's floor and upper and jaw gingiva the combined treatment with chemotherapy and external radiotherapy presented better results than isolated external radiotherapy. (author)

    Purpose: A prospective study of sequential surgery, abdominopelvic radiotherapy and single agent alkylating chemotherapy was conducted to evaluate survival and toxicity in the management of ovarian carcinoma. Methods: From 1970-1976, 95 women with stage I-III epithelial ovarian carcinoma were scheduled to receive postoperative radiotherapy consisting of 20.0 Gy to the whole abdomen (1.0 Gy/day), a 29.75 Gy pelvic boost (1.75 Gy/day) and 10 subsequent courses of Melphalan (1 mg/kg/course). Endpoints were overall survival, disease-free survival(DFS), and acute and chronic toxicity. Results: The evaluable 94 patients included 19 stage I, 25 stage II, and 50 stage III. Of the latter, 21 had no palpable disease postoperatively (IIIN) and 29 had postoperative palpable disease (IIIP). Overall survival at 5, 10, 15 and 20 years was 42%, 30%, 23% and 22%. DFS for the entire group was 54% at 5 years and remained 50% from 10 to 25 years. All but two recurrences were noted within the first 27 months. No recurrence or treatment-related deaths occurred after 8 years. After 10 years, the survival of the study group became parallel to the general population. Prognostic factors were only related to stage (p<.001) and the presence of postoperative palpable disease(p<.001). DFS at 25 years was 95 % for stage I, 71% at 5 years and 66% from 10 to 25 years for stage II, and 17% at 5 years and 11% thereafter for stage III patients(p<.001). Although no stage IIIP patients were cured, 25% lived beyond 2 years. Five year DFS was significantly better in IIIN (45%) vs. IIIP (0%) patients (p<.001). The 65 patients without postoperative palpable disease, (stage I-IIIN) achieved DFS at 5 and 25 years of 69%, and 61%, respectively. Of 31 patients undergoing a second-look surgery, 84% were found to be free of tumor. Two recurred at 3.5 and 7 years after surgery. Acute tolerance was acceptable. Chronic toxicity included an 11.7% rate of small bowel obstruction requiring surgery and a 3% rate of

    We aimed to clarify renal functional changes long term and serious urological complications in women with cervical cancer who undergo radical hysterectomy followed by pelvic radiotherapy and/or platinum-based chemotherapy to treat the initial disease. Data on 380 women who underwent radical hysterectomy at the National Kyushu Cancer Center from January 1997 to December 2013 were reviewed. Main outcome measures were the estimated glomerular filtration rate (eGFR) and monitored abnormal urological findings. Postoperative eGFR was significantly lower than preoperative eGFR in 179 women with surgery alone and in 201 women with additional pelvic radiotherapy and/or chemotherapy (both P types of univariate analyses for eGFR reduction in women after treatment showed that older age, advanced stage, pelvic radiotherapy, and platinum-based chemotherapy were significant variables on both analyses. Two types of multivariate analyses showed that platinum-based chemotherapy or pelvic radiotherapy were associated with impaired renal function (odds ratio 1.96, 95% confidence interval 1.08-3.54 and odds ratio 2.85, 95% confidence interval 1.12-7.24, for the respective analyses). There was a higher rate of bladder wall thickening in women with pelvic radiotherapy had than those without it (17.4% vs. 2.7%, P chemotherapy and/or postoperative pelvic radiotherapy. Serious and life-threatening urological complications are rare, but surgeons should be aware of the possibility during the long follow-up. © The Author 2017. Published by Oxford University Press.

    Retinoblastoma is the most common primary intraocular malignancy of childhood. A potentially curable cancer, its treatment has improved significantly over the last few decades. Various studies show that while enucleation remains the standard of care for advanced intraocular tumours, conservative modalities that can result in globe salvage and preservation of useful vision are being increasingly employed. Such modalities include systemic chemotherapy, focal consolidation with transpupillary thermo therapy, laser photocoagulation and cryotherapy, plaque brachytherapy, and delivery of local chemotherapy using subconjunctival, sub-tenon, or intra-arterial routes. When used alone or in combination, these treatment modalities can help in avoidance of external beam radiotherapy or enucleation, thus reducing the potential for long-term side effects, while salvaging useful vision. Radioactive plaque brachytherapy has an established role in selected patients with intraocular retinoblastoma. Local injections of chemotherapeutic agents via the sub-tenon or sub-conjunctival route have been used with varying degrees of success, usually as an adjunct to systemic chemotherapy. Intra-arterial ophthalmic artery delivery of melphalan has shown promising results.

    Cervical cancer is the second commonest cancer among women up to 65 years of age and is the most frequent cause of death from gynaecological cancers worldwide. Sources suggest that a very high proportion of new cervical cancer cases in developing countries are at an advanced stage (IB2 or more) and more than a half of these may be stage III or IV. Cervical cancer staging is based on findings from clinical examination (FIGO) staging). Standard care in Europe and US for stage IB2 to III is non-surgical treatment (chemoradiation). However in developing countries, where there is limited access to radiotherapy, locally advanced cervical cancer may be treated with a combination of chemotherapy and hysterectomy (surgery to remove the womb and the neck of the womb, with or without the surrounding tissues). It is not certain if this improves survival. Therefore, it is important to systematically assess the value of hysterectomy in addition to radiotherapy or chemotherapy, or both, as an alternative intervention in the treatment of locally advanced cervical cancer (stage IB2 to III). To determine whether hysterectomy, in addition to standard treatment with radiation or chemotherapy, or both, in women with locally advanced cervical cancer (stage IB2 to III) is safe and effective compared with standard treatment alone. We searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL, MEDLINE, EMBASE and LILACS up to February 2014. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. We searched for randomised controlled trials (RCTs) that compared treatment protocols involving hysterectomy versus radiotherapy or chemotherapy, or both, in women with advanced stage (IB2 to III) cervical cancer presenting for the first time. We assessed study eligibility independently, extracted data and assessed risk of bias. Where possible, overall and progression or disease-free survival outcomes were synthesised

    The authors report a prospective assessment of toxicity a treatment comprising an adjuvant chemo-radiotherapy after neo-adjuvant chemotherapy and a comparison with a treatment comprising only radiotherapy. Two sets of patients have been treated for a breast cancer between 1997 and 2002 by association of neo-adjuvant chemotherapy, surgery and radiotherapy with or without concomitant chemotherapy. Late toxicity has been assessed prospectively according to Common Terminology Criteria for Adverse Events. Acute toxicity has been noticed in medical files. The analysis of 142 treatments reveals that the concomitant administration of chemotherapy to radiotherapy after neo-adjuvant chemotherapy and surgery is associated with an increase of acute toxicity without increase of long term toxicity.

    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)

    Cellulitis is a previously unreported complication of conservative surgery and radiation therapy for early stage breast cancer. Patients who presented with breast cellulitis after conservative therapy are described. Eleven patients that developed cellulitis of the breast over a 38-month period of observation are the subject of this report. Clinical characteristics of patients with cellulitis and their treatment and outcome are reported. Potential patient and treatment-related correlates for the development of cellulitis are analyzed. The risk of cellulitis persists years after initial breast cancer therapy. The clinical course of the patients was variable: some patients required aggressive, long-duration antibiotic therapy, while others had rapid resolution with antibiotics. Three patients suffered from multiple episodes of cellulitis. Patients with breast cancer treated with conservative surgery and radiotherapy are at risk for breast cellulitis. Systematic characterization of cases of cellulitis may provide insight into diagnosis, prevention, and more effective therapy for this uncommon complication. 15 refs., 1 fig., 2 tabs

    Full Text Available Abstract Background To analyze the rate of larynx preservation in patients of locally advanced hypopharyngeal cancer treated with intensity modulated radiotherapy (IMRT plus concurrent chemotherapy, and compare the results with patients treated with primary surgery. Methods Between January 2003 and November 2007, 14 patients were treated with primary surgery and 33 patients were treated with concurrent chemoradiotherapy (CCRT using IMRT technique. Survival rate, larynx preservation rate were calculated with the Kaplan-Meier method. Multivariate analysis was conducted for significant prognostic factors with Cox-regression method. Results The median follow-up was 19.4 months for all patients, and 25.8 months for those alive. The 5-year overall survival rate was 33% and 44% for primary surgery and definitive CCRT, respectively (p = 0.788. The 5-year functional larynx-preservation survival after IMRT was 40%. Acute toxicities were common, but usually tolerable. The rates of treatment-related mucositis (≥ grade 2 and pharyngitis (≥ grade 3 were higher in the CCRT group. For multivariate analysis, treatment response and cricoid cartilage invasion strongly correlated with survival. Conclusions IMRT plus concurrent chemotherapy may preserve the larynx without compromising survival. Further studies on new effective therapeutic agents are essential.

    Chemotherapy and primary site radiation therapy were compared to chemotherapy alone in a randomized study of 125 patients with small cell cancer of the lung. The sites of initial relapse, as well as disease free and overall survival were analyzed. Radiotherapy to the primary site reduced the rate of local relapse, but median survival was not prolonged in patients with either limited or extensive disease, when the radiation therapy-chemotherapy group was compared to the group that received chemotherapy alone

    Purpose: To compare two different timings of radiation treatment in patients with breast cancer who underwent conservative surgery and were candidates to receive adjuvant cyclophosphamide, methotrexate, and fluorouracil (CMF) chemotherapy. Methods and Materials: A total of 206 patients who had quadrantectomy and axillary dissection for breast cancer and were planned to receive adjuvant CMF chemotherapy were randomized to concurrent or sequential radiotherapy. Radiotherapy was delivered only to the whole breast through tangential fields to a dose of 50 Gy in 20 fractions over 4 weeks, followed by an electron boost of 10-15 Gy in 4-6 fractions to the tumor bed. Results: No differences in 5-year breast recurrence-free, metastasis-free, disease-free, and overall survival were observed in the two treatment groups. All patients completed the planned radiotherapy. No evidence of an increased risk of toxicity was observed between the two arms. No difference in radiotherapy and in the chemotherapy dose intensity was observed in the two groups. Conclusions: In patients with negative surgical margins receiving adjuvant chemotherapy, radiotherapy can be delayed to up to 7 months. Concurrent administration of CMF chemotherapy and radiotherapy is safe and might be reserved for patients at high risk of local recurrence, such as those with positive surgical margins or larger tumor diameters

  13. Combined chemotherapy and radiotherapy in the treatment of lung cancer

    In the past decade the prognosis of patients with locally advanced lung cancer has not been altered significantly. In both small and non-small cell lung cancer cure rates are poor and 5-year survival rate still has not exceeded the 5% borderline. Despite of initially high response rates, a vast majority of patients suffered from tumor progression within 2 years after the start of treatment. Sites of tumor progression are either the primary tumor or the occurrence of distant metastases. Therefore, improvements of both local and systemic tumor control are necessary to increase long-term survival rate in lung cancer. Combined chemo- and radiotherapy may be an appropriate treatment approach to reach these aims. In patients with locally advanced lung cancer combined chemo-radiotherapy aims at overcoming radio- and chemo-therapy resistance as a cause of local treatment failure and at early eradication of distant micrometastases as a cause of systemic treatment failure.

    Purpose/Objective: Since 1992, we have been using neoadjuvant chemotherapy to reduce the radiation dose and irradiated volume in the treatment of intracranial germinomas. This study evaluates the initial response and complications of the treatment and also the IQ score and pituitary function of patients before radiotherapy. Materials and methods: Fifteen patients with histologically confirmed intracranial germinomas were treated between 1992 and 1997. Six patients with solitary pure germinoma received 3 to 4 courses of etoposide and cisplatin (EP regimen) followed by localized irradiation of 24Gy (in 12 fractions within 3 weeks). Three patients with germinoma with syncytiotrophoblastic giant cells (STGC) and 4 patients with multifocal pure germinoma received 3 to 5 courses of ifosfamide, cisplatin and etoposide (ICE regimen), followed by localized irradiation of 24 Gy. Two patients with disseminated pure germinoma received 2 to 4 courses of ICE regimen followed by craniospinal irradiation of 24 Gy. In the planning of localized irradiation, the treatment field was determined so as to cover the tumor with a margin of 2cm. The IQ score and pituitary function before radiotherapy were also examined. MRI was performed in all patients one month after the completion of treatment and every 6 months in the follow-up study. The treatment data of our institute before 1991, as historical control, was analyzed and compared to that of the present study. Results: Complete remission (CR) was obtained in all patients after the treatment. One patient with germinoma with STGC experienced recurrence out of the field at 39 months after surgery. He was re-treated with salvage therapy including the ICE regimen and obtained a second complete remission. All patients are alive without disease with a median follow-up period of 29 months. The examination of IQ score and pituitary function before radiotherapy revealed mental retardation in 2 patients (22%) and hypopituitarism in 13 patients (86

    Following single-agent or combination chemotherapy, 9 patients with epithelial carcinoma of the ovary had elective second-look laparotomy. Macroscopic intraperitoneal disease was resected in 4 patients. Therefore, after the laparotomy, all 9 patients had only biopsy-proven, microscopic residual disease, and they received whole abdominopelvic irradiation. Hematological tolerance was satisfactory, with only 2 patients developing asymptomatic thrombocytopenia. Mild gastrointestinal reactions, while frequent during radiotherapy, did not interrupt treatment in any patient. After follow-up ranging from 6 to 28 months (median 12 months), 2 patients died of cancer, 2 were alive with cancer, 3 were alive without clinical recurrence, and 2 were alive without biopsy-proven recurrence. Bowel complication occurred in 4 patients: 2 developed intestinal obstruction due to recurrent tumor, 1 developed subacute bowel obstruction which spontaneously resolved, and 1 patient required bowel resection because of a radiation complication. This study indicated that after single- or multiple-drug chemotherapy, most patients could complete the course of whole abdominopelvic irradiation. Gastrointestinal complications could be secondary to radiation damage or to recurrent tumor. While whole abdominopelvic irradiation was not an effective second-line treatment, some long-term survivors could still be expected

    Treatment results of 49 patients (25, limited disease, LD, 24, extensive disease, ED) with small cell lung cancer were retrospectively analyzed. Fifteen patients received chemotherapy with Cyclophosphamide (CPM) and Vincristine (VCR) following thoracic radiotherapy (RT). Twenty-two patients were given induction chemotherapy with CPM, Adriamycin (ADM), and VCR and were followed by thoracic RT. Other chemotherapy consisted of CPM, VCR, Methotrexate, and ADM in 2 patients, 5-FU, CPM, Mitomycin C, and Toyomycin in 1 patient. The remaining 9 patients (2, LD, 7, ED) were treated with RT alone. The response rate was 80 % (64 % CR; 16 % PR) for LD patients and 33 % (4 % CR; 29 % PR) for ED patients (P < 0.001). The three-year survival (Kaplan-Meier's product) of all patients was 14 %, with a median survival time (MST) of 8 months. For patients with LD, the 3-year survival was 27 % (MST 15 months). Survival of patients with ED was 14 % at 1 year, 0 % at 2 year (MST 5.5 months). The difference between these figures was statistically significant (P < 0.0003). The 3-year survival and relapse-free survival for complete responders with LD were 43 % (MST 21 months) and 36 % (median CR duration, 11.5 months) respectively. Six of 16 complete responders with LD are alive and well at over 2 years. Local recurrence rate of the complete responders with LD was 28.8 %. None of the 7 complete responders given more than 48 Gy relapsed within the radiation field. We believe that the addition of thoracic RT to patients with LD is necessary for the control of the primary tumors and for long-term disease-free survival. (author)

    The authors studied the effect of a chemo-/radiotherapy or radio-/chemotherapy on 52 cases of microcellular bronchial carcinoma, classification ''limited disease''. The survival curves were slightly better for the patients submitted to primary chemotherapy, but the difference was not statistically significant, and the curves coincided again after 18 months. 60 to 80% of the patients had no complaints or only unimportant complaints during more than half of their survival time. In 23 patients with ''extensive disease'' who received only a symptomatic therapy or a combined palliative chemotherapy, chemotherapy had a slightly better effect, but this was not statistically significant.

    36 patients with advanced cervical carcinoma stage III (24 patients) and stage IV (12 patients) entered a feasibility study of a radiotherapy and chemotherapy combination. The first three chemotherapy courses consisted of cis-platinum alone and were interdigitated with radiotherapy. Six more courses composed of an association of cis-platinum and cyclophosphamide were given after the completion of radiotherapy. Radiotherapy was delivered in two courses of 25 Gy separated by a gap of 2 weeks. The overall 4-year survival rate, cumulative loco-regional failure rate, and cumulative meatstasis rate were respectively 44%, 56% and 30% in stage III and 28%, 83% and 74% in stage IV. The incidence of immediate and late complications was low: no patient had her radiotherapy stopped because of an intolerance and two patients had their chemotherapy stopped because of an haematological intolerance. Only one patient presented a severe late clinical complication (small bowel injury). 29 refs.; 2 figs.; 4 tabs

    A man aged 33 with poorly controlled hypertension who had been treated with radiotherapy and combination chemotherapy for testicular teratoma 8 years earlier was found on arteriography to have 75% stenosis of the left renal artery and occlusion of the right renal artery. The stenosis was dilated by transluminal angioplasty and the hypertension adequately controlled. Patients who develop high blood pressure after abdominal radiotherapy with or without chemotherapy should be investigated for renal artery stenosis. (author)

  3. Combined radiotherapy and chemotherapy for high-grade brain tumours

    Barazzuol, Lara

    Glioblastoma (GBM) is the most common primary brain tumour in adults and among the most aggressive of all tumours. For several decades, the standard care of GBM was surgical resection followed by radiotherapy alone. In 2005, a landmark phase III clinical trial coordinated by the European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) demonstrated the benefit of radiotherapy with concomitant and adjuvant temozolomide (TMZ) chemotherapy. With TMZ, the median life expectancy in optimally managed patients is still only 12-14 months, with only 25% surviving 24 months. There is an urgent need for new therapies in particular in those patients whose tumour has an unmethylated methylguanine methyltransferase gene (MGMT) promoter, which is a predictive factor of benefit from TMZ. In this dissertation, the nature of the interaction between TMZ and radiation is investigated using both a mathematical model, based on in vivo population statistics of survival, and in vitro experimentation on a panel of human GBM cell lines. The results show that TMZ has an additive effect in vitro and that the population-based model may be insufficient in predicting TMZ response. The combination of TMZ with particle therapy is also investigated. Very little preclinical data exists on the effects of charged particles on GBM cell lines as well as on the concomitant application of chemotherapy. In this study, human GBM cells are exposed to 3 MeV protons and 6 MeV alpha particles in concomitance with TMZ. The results suggest that the radiation quality does not affect the nature of the interaction between TMZ and radiation, showing reproducible additive cytotoxicity. Since TMZ and radiation cause DNA damage in cancer cells, there has been increased attention to the use of poly(ADP-ribose) polymerase (PARP) inhibitors. PARP is a family of enzymes that play a key role in the repair of DNA breaks. In this study, a novel PARP inhibitor, ABT-888

    Full Text Available Neoadjuvant chemotherapy (NAC is widely used in locally advanced breast cancer (BC treatment. The role of postmastectomy radiotherapy (PMRT after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6% underwent PMRT and 72 cases (42.4% did not receive radiation. At a median follow-up period of 7.7 years (range 2–16 for the whole cohort, median time to locoregional recurrence (LRR was 3.3 years (range 0.7–12.4. The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51–16.52; P=0.035, extracapsular extension (HR 2.18, 1.37–3.46; P=0.009, and estrogen receptor positive disease (HR 0.57, 0.36–0.90; P=0.003. Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P=0.015. Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

  5. Multimodal treatment combining chemotherapy, hyperthermia and radiotherapy for ovarian cancer

    There has been increasing interest in the use of heat in the treatment of cancer. Theoretically cells are the most sensitive to ionizing radiation at mitosis, whereas the cycle phase that is the most resistant to ionizing radiation namely late in the DNA. Synthetic phase (late S) is the most sensitive to hyperthermia. Hyperthermia has been reported to enhance the cytocidal effects of several active chemotherapeutic agents. When thermal potentiation of chemotherapeutic agents against malignant cells is contemplated, normal tissues have a relatively high ambient blood flow which increases in response to thermal stress, thereby dissipating heat, compared to tumors. Tumors, with relatively poor blood flow and a responsive neovasculature, are in capable of augmenting flow and acting as a heat reservoir. This is the phenomenon of a heat reservoir which is one factor to enhance the cytocidal effects of several active anticancer agents for enhancing the uptake in tumor. The importance is in the adjuvant chemotherapy treated for post operative, advanced and recurrent ovarian cancer. Heating enhances the effects of radiotherapy and chemotherapy. Thirty patients with ovarian cancer were subjected to the multidisciplinary treatment with combination of hyperthermochemotherapy and radiation. The 30 patients consisted of 18 with endometrioid adenocarcinoma and 7 with serious post operative or recurrent status. Two types of equipments with rediofrequencies of 70 MHz (BSD-1000) or 434 MHZ (TAG MED·HS 434) were used for hyperthermia. Chemotherapeutic agents such as adriamycin, cis DDP, cyclophosphamide and etoposide were injected intravenously. Arterial infusion with reservoir was very effective in advanced stage of ovarian cancer. No severe or fatal side effects were observed. Hyperthermochemotherapy is useful and effective for the postoperative management or the treatment of recurrent cancer of the ovary. (J.P.N.)

    Objective: To compare the therapeutic effects, toxic side effects of late-course three dimensional conformal radiotherapy plus chrono-chemotherapy (DDP + 5-FU/CF) and conventional radiotherapy plus chemotherapy for nasopharyngeal carcinoma (NPC). Methods: Eighty -six NPC patients admitted from Feb. 2001 to Jan. 2002 were divided randomly into two groups: 1. Chrono-chemotherapy + late course three dimensional conformal radiotherapy(CCR) group-44 patients were treated by late course three dimensional conformal radio-therapy plus chrono-chemotherapy, and 2. Routine-chemotherapy-radiotherapy (RCR) group-42 patients were treated by routine chemotherapy plus radiotherapy. The patients in CCR and RCR group were comparable in age, KPS, stage and pathology. All patients were treated by combined chemotherapy and radiotherapy, with chemotherapy stared 2 weeks ahead of radiotherapy. Chemotherapy: Braun pump was used in all drug infusions; 1. CCR group-DDP 80 mg/ m 2 starting from 10:00 until 22:00, 5-Fu 750 mg/d/m 2 starting from 22:00 until 10:00 next day, CF 200 mg/d/m 2 starting from 10:00 every day, infused at normal speed. These drugs were given for 3 days, 14 days as one cycle, totally 2 cycle, and 2. RCR group-with the same drugs at the same total dose, only with the difference being DDP and CF given QD, starting from 10:00 but at the normal speed. 5-Fu was given through-out the day and continuously for 3 days, totally for 2 cycles. Radiotherapy: linear accelerator irradiation was given to either group. Composite facio-cervical field + anterior cervical tangential field to D T 40 Gy/4w, followed by the coned down per-auricular field plus anterior tangential field or β beam irradiation. In CCR group, after D T 40gy/4w, late course 3-dimensional conformal radiotherapy (3DCRT) was used to add D T 30Gy/3w. In RCR group, routine radiotherapy of 40 Gy/w was supplemented with 30 Gy/3w. The total dose in either group was 70 Gy/7w at the nasopharynx, D T 60-70 Gy/6-7w at the

    The low incidence, the wide histological spectrum and the natural, sometimes slow, evolution of malignant parotid gland tumours do not allow to easily establish the impact of their treatments. At present, clinical data come from retrospective cohort analysis, whereas randomized phase II-III trials are confidential. Moreover conclusions from these studies are controversial. We present here the therapeutic highlights of parotid cancers: surgery, with the particular concern of facial nerve preservation; and adjuvant treatment essentially based on radiotherapy. This review focused on adjuvant care explores the indications and the technical aspects of radiation, as well as the role of concurrent chemotherapy. (authors)

    Objective: To retrospectively analyze the outcome of locally advanced non-small cell lung cancer patients treated with radiotherapy and chemoradiotherapy. Methods: 289 patients who were treated either by radiotherapy alone (168 patients) or radiotherapy plus chemotherapy (121 patients) from Dec. 1999 to Dec. 2002 were entered into the database for analysis. Pathological types: squamous cancer (152), adenocarcinoma(74), squamoadenocarcinoma(2) and other types (2). 24 showed cancer unclassificable and 35 were diagnosed without pathological proof. Stages: 74 had III A and 215 III B stage disease. Among the 121 patients treated with combined modality, 24 were treated with concurrent chemoradiotherapy, 78 radiotherapy after chemotherapy(C + R), and 19 radiotherapy followed by chemotherapy(R + C). In patients treated by concurrent chemoradiotherapy or C + R, 38 received consolidation chemotherapy after induction treatment. Results: The 1-, 3-, 5-year overall survival, and the median survival were: 45% , 16% , 8%, and 16.2 months for all patients; 57%, 27%, 11%, and 21.7 months for stage IIIA; 41%, 12%, 7%, and 15.3 months for IIIB. By logrank test, clinical stage, KPS performance, tumor volume, hemoglobin level before treatment, consolidation chemotherapy, radiation dose, and response to treatment showed statistically dramatic impact on overall survival. The overall survival rate and median survival time were slightly higher in the combined group than in the radiotherapy alone group, but the difference is statistically insignificant. In Cox multivariable regression, stage and consolidation chemotherapy were independent prognostic factors; KPS performance, radiation dose, and response to treatment were at the margin of statistical significance. Esophagitis and pneumonitis of Grade II or higher were 24% and 8%, respectively. Failure sites included in the thorax(41%), outside of thorax(48%), and both in and outside the thorax(11%). There was no difference between the

    We studied in this series about histopathologic changes in radiotherapy of squamous cell carcinoma of head and neck. Then we recognized that radiotherapy combined with chemotherapy is useful for radioresistant squamous cell carcinoma. In this series, we studied about cancer of the tongue as one of the keratinizing squamous cell carcinoma and used Bleomycin as a chemotherapeutic drug. We commented as follows: 1. Radiotherapy combined with chemotherapy had benefit decreasing of a period for radium therapy. 2. Severs complication was not occurred in this series, then this combined therapy was useful for aged or handicapped patient. (author)

    Purpose/Objectives: A prospective study for localized esophageal cancer using hyperfractionated radiotherapy(1.2Gy/fx, BID, 48Gy/4wks) with concurrent chemotherapy FP(CDDP 60mg/M 2 /d, d1 and d29, 5-FU 1gm/M 2 /d, continuous infusion d2-6 and d30-34) followed by esophagectomy has been conducted to evaluate the efficacy and toxicity of chemoradiation followed by surgery and curative potential of transhiatal esophagecomy. We analyze the clinical/pathological response and toxicity of preoperative regimen and report the patterns of failure and the survival of patients in esophagectomy group compared with patients who treated with definitive radiotherapy. Materials and Methods: Since May 1993, 48 patients with localized esophageal cancer entered on this trial and 42 patients were evaluated for response and toxicity in 4 weeks after completion of preoperative regimen. 15 patients underwent surgery and 5 are waiting for surgery. Among 22 patients who refused the surgery, 11 patients received the definitive radiotherapy (≥60Gy) and 11 of them refused further therapy. In 41 men and 1 women with median age of 61 years old (range 41-75 years), 8 patients were staged as SI, 22 SII, and 12 SIII with endoscopic, histologic and radiologic evaluation. Results: Clinical tumor response was observed in 79%((33(42))) and 66%((23(35))) of patients who had histologic evaluation showed complete pathologic response. (13(15)) who underwent surgery achieved complete resection and surgical specimen of 7(47%) patients showed no histologic evidence of disease. 20% ((3(15))) surgical mortality was observed. Among 15 patients who underwent surgery, 53% ((8(15))) are alive NED in 3-19 months (median 7 months), 1 patient is alive with disease in 3 months, 2 patients died of progression, 3 postoperative mortality and 1 patient died of lung cancer in 5 months. Among 11 patients who received curative radiotherapy, 6 are alive with good performance, NED in 9-15 months (median 10 months), 3 are alive

    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)

    1985-01-01

    Sixty-three evaluable patients with limited small cell lung carcinoma were entered into two pilot studies alternating 6 cycles of combination chemotherapy with 3 courses of mediastinal radiotherapy as induction treatment. The first course of radiotherapy started 10 days after the second cycle of chemotherapy; there was a 7 day rest between chemotherapy and radiotherapy courses. This 6 month induction treatment was followed by a maintenance chemotherapy. The total mediastinal radiation dose was increased from 4500 rad in the first study to 5500 rad in the second. Both protocols obtained a complete response (CR) rate of greater than 85%. Local control at 2 years was 61% in the first study and 82% in the second. Acute and delayed toxicity effects are discussed

A 15-year-old boy with a history of acute lymphoblastic leukemia, at the age of 7, underwent chemotherapy and 14 Gy of radiotherapy to the whole brain. He was admitted to our department due to the development of aphasia, right hemiparesis and generalized convulsive seizure. MRI showed an irregularly enhanced mass in the left frontal lobe. A gross total removal of the tumor was performed and histological examination showed it to be PNET. Postoperatively, the patient underwent 20 Gy of radiotherapy to the whole brain and 42 Gy of local radiotherapy. Follow-up MRI showed no evidence of recurrent tumor 4 months after the radiotherapy. This tumor was thought to be a secondary brain tumor arising in this survivor of childhood acute lymphoblastic leukemia and it is a rare complication of successful leukemia treatment. (author)

    Since Jan. 1991 a prospective randomized study for Stage III unresectable non small cell lung cancer(NSCLC) has been conducted to evaluate the response rate and tolerance of induction chemotherapy with MVP followed by hyperfractionated radiotherapy and evaluate the efficacy of maintenance chemotherapy in Asan Medical Center. All patients in this study were treated with hypefractionated radiotherapy (120 cGy/fx BID, 0480 cGy/54 fx) following 3 cycles of induction chemotherapy, MVP (Mitomycin C 6 mg/m2, Vinblastin B mg/ m2, Cisplatin 60 Mg/ m2) and then the partial and complete responders from induction chemotherapy were randomized to 3 cycles of adjuvant MVP chemotherapy group and observation group. 48 patients were registered to this study until December 1992; among 48 patients 3 refused further treatment after induction chemotherapy and 6 received incomplete radiation therapy because of patient refusal, 39 completed planned therapy. Twenty-three(58%) patients including 2 complete responders showed response from induction chemotherapy. Among the 21 patients who achieved a partial response after induction chemotherapy, 1 patient rendered complete clearance of disease and 10 patients showed further regression of tumor following hypefractionated radiotherapy. Remaining 10 patients showed stable disease or progression after radiotherapy. Of the sixteen patients judged to have stable disease or progression after induction chemotherapy, seven showed more than partial remission after radiotherapy but nine showed no response in spite of radiotherapy. Of the 35 patients who completed induction chemotherapy and radiotherapy, 25 patients(64%) including 3 complete responders showed more than partial remission. Nineteen patients were randomized after radiotherapy. Nine patients were allocated to adjuvant chemotherapy group and 4/9 shewed further regression of tumor after adjuvant chemotherapy. For the time being, there is no suggestion of a difference between the adjuvant

    Spontaneous canine osteosarcomas is an excellent model for of human osterosarcoma. Twenty dogs with obsteorsarcoma were treated with intravenous or intraarterial cisplatin with or without radiation therapy. This treatment was given 3 weeks prior to limb sparing surgery involving excision of the tumor and allograft replacement. The excised tumor specimen was examined for complete removal and percentage of necrotic tumor measured by planimetry. Intraveneous and intraarterial cisplatin and radiation methods were compared. Data discussing rate of disease development and recurrences is given

    Increased risks of solid tumors after older radiotherapy strategies for testicular cancer (TC) are well established. Few population-based studies, however, focus on solid cancer risk among survivors of TC managed with nonradiotherapy approaches. We quantified the site-specific risk of solid cancers among testicular nonseminoma patients treated in the modern era of cisplatin-based chemotherapy, without radiotherapy. Standardized incidence ratios (SIRs) for solid tumors were calculated for 12,691 patients with testicular nonseminoma reported to the population-based Surveillance, Epidemiology, and End Results program (1980 to 2008) and treated initially with either chemotherapy (n = 6,013) or surgery (n = 6,678) without radiotherapy. Patients accrued 116,073 person-years of follow-up. Two hundred ten second solid cancers were observed. No increased risk followed surgery alone (SIR, 0.93; 95% CI, 0.76 to 1.14; n = 99 solid cancers), whereas significantly increased 40% excesses (SIR, 1.43; 95% CI, 1.18 to 1.73; n = 111 solid cancers) occurred after chemotherapy. Increased risks of solid cancers after chemotherapy were observed in most follow-up periods (median latency, 12.5 years), including more than 20 years after treatment (SIR, 1.54; 95% CI, 0.96 to 2.33); significantly increased three- to seven-fold risks occurred for cancers of the kidney (SIR, 3.37; 95% CI, 1.79 to 5.77), thyroid (SIR, 4.40; 95% CI, 2.19 to 7.88), and soft tissue (SIR, 7.49; 95% CI, 3.59 to 13.78). To our knowledge, this is the first large population-based series reporting significantly increased risks of solid cancers among patients with testicular nonseminoma treated in the modern era of cisplatin-based chemotherapy. Subsequent analytic studies should focus on the evaluation of dose-response relationships, types of solid cancers, latency patterns, and interactions with other possible factors, including genetic susceptibility.

    Full Text Available Purpose: Treatment of advanced Non small cell lung cancer (NSCLC often produces dismal results. Combination of available treatment modalities has reportedly improved the outcome. A prospectively randomized trial was conducted, comparing combined treatment modalities versus radiotherapy alone, in treatment of unresectable NSCLC. Materials and Methods: A total of 103 patients were randomized to three groups. In group ′A′, 32 patients received radiotherapy alone (6500 cGy/30 fraction. In group ′B′, 35 patients received neoadjuvant chemotherapy (Cisplatin 80 mg/m2 on day 1 and Etoposide 100 mg/m day 1-3 intravenously q3 weeks for 3 cycles, followed by radiotherapy (6000 cGy/30 fractions and 3 more cycles of Chemotherapy, with the same regimen. In group ′C′, 36 patients received radiotherapy (5000 cGy/25 fractions with concurrent chemotherapy (ciplatin 20 mg/m2 + Etoposide 75 mg/m2 intravenously on day 1-5 and day 22-26, followed by 2 more cycles of chemotherapy,q3 weeks with the same regimen. Results: Initial treatment responses were significantly higher in group ′B′ ( P P Conclusion: Addition of chemotherapy with radiation in unresectable NSCLC improves response rates, time to tumour progression and disease free survival, though the same effect is not translated in overall survival.

    For patients with operable esophagogastric cancer, peri-operative chemotherapy confers a significant overall survival benefit compared to surgery alone, however only 30-40% of patients demonstrate histopathological response. It is unclear whether those with no neoadjuvant chemotherapy response should go onto receive adjuvant chemotherapy, as no further benefit may be conferred. Esophagogastric cancers were prospectively captured with associated histopathological tumor regression grades following neoadjuvant chemotherapy. This cohort was then interrogated for clinico-pathological and survival outcomes. Following neoadjuvant chemotherapy and surgery, patients with chemotherapy responsive cancers, who were administered adjuvant chemotherapy gained a significant overall survival benefit. Multivariate Cox analysis, demonstrated a final adjusted hazard ratio for adjuvant therapy of 0.509; (95%CI 0.28-0.93); P = 0.028. In contrast, patients with non-responsive tumors, who underwent adjuvant chemotherapy, did not show any survival benefit. Chemotherapy toxicity was prevalent and contributed to only half of patients receiving adjuvant chemotherapy. These results suggest the benefit of the adjuvant portion of chemotherapy is limited to those who demonstrate a histopathological response to neoadjuvant chemotherapy. The administration of the adjuvant portion of chemotherapy to patients without a response to neoadjuvant chemotherapy may not provide any survival benefit, while potentially causing increased morbidity. © 2017 Wiley Periodicals, Inc.

    A cohort study designed to evaluate the carcinogenicity of treatment for Hodgkin's disease (HD) was begun in 1976. This report describes 1,553 patients diagnosed with HD in 1940-75 and presents an analysis of follow-up findings through 1976. Twenty-seven cancers (excluding basal cell and squamous cell carcinomas of skin, trichoepitheliomas, and in situ carcinomas of cervix uteri) were observed 1 year or more after diagnosis of HD, including 6 leukemias. The relative risk (RR) of leukemia in patients treated with intensive chemotherapy with or without radiotherapy relative to general population incidence rates was 140 (95% confidence limits: 50,300). In the subgroup treated with both intensive radiotherapy and intensive chemotherapy, the RR of leukemia was 270 (95% confidence limits: 56,800). No leukemia occurred after treatment with intensive radiotherapy without chemotherapy. For cancers other than leukemia and for non-HD lymphomas, RR was generally not significantly different from the null value one

    Frozen tissue from primary tumours of 152 premenopausal breast cancer patients, who participated in a trial comparing radiotherapy with adjuvant chemotherapy (cyclophosphamide, methotrexate, 5-fluorouracil, CMF), was analysed for c-erbB-2 protein expression, measured by flow cytometry. The relative risk of distant recurrence or death in the chemotherapy group as compared with the radiotherapy group was 3.0 (95% confidence interval (CI) 1.1-7.8) for patients whose tumours showed high c-erbB-2 levels and 0.87 (95% CI 0.43-1.7) for those with tumours with low levels of c-erbB-2 protein. Patients with highly proliferative tumours that did not overexpress c-erbB-2 benefited most, in terms of survival, from CMF. In addition, we found an increased risk of locoregional recurrence for tumours overexpressing c-erbB-2 when radiotherapy was replaced by chemotherapy. (author)

    Full Text Available The purpose of this study was to find a more efficacious treatment for patients with primary central nervous system Lymphoma using chemotherapy. The objective was to determine the optimal time for radiotherapy treatment in relation to chemotherapy. Retrospective evaluation in patients with brain lymphoma was conducted from 1992 to 1998. Twenty-three patients were evaluated. Patients were divided into two groups based on the timing of radiotherapy in relation to the chemotherapy. The first group of patients (n=13 initially received radiotherapy followed by chemotherapy. Five of these patients receied classic CHOP (cyclophosphamide, Doxorubicine, Vincistine and Prednisone, six patients received Cis-platin (60 Megs/M2 and Etoposide (120 Megs/M2 and two patients received Cis-platin (60 Megs/M2, Etoposide (120 Megs/M2 and Cytarabine (600 Megs/M2 every 2 to 3 weeks. The second group of patients (Group II, n=10 received the followeing treatment regimen: a course of BCNU 120 Megs/M2 with Ifosfamide 1200 Megs/M2, Mesna and Etoposide 120 Megs/M2 on the first day of treatment (course A. Two weeks later, treatment was continued with a course of Cis-platin 35 Megs/M2 and Cytarabine 600 Megs/M2 (course B. The treatment was continued 14 days later with a course of Mitoxantron 12 Megs/M2, Ifosfamide 1200 Megs/M2 puls Mesna (course C. After the fourth week of chemotherapy, these patients received radiotherapy to the brain (5000 RADS in 4 weeks. During radiotherapy and at the beginning of course chemotherapy, intrathecal therapy with Methorexate 12 Megs/M2 and Cytarabine 60 Megs/M2 was given. Immediately after radiotherapy, the same chemothotrexate 12 Megs/M2 and Cytarabine 60 Megs/M2 was given. Immediately after radiotherapy, the same chemotherapy treatment was repeated to a total of 3 times. After complete clearance of the tumor determined by MRI and absence of tumor cells in the spinal fluid, the chemotherapeutic regimen was repeated one last time. The

    Purpose/Objective: The precise role of salvage radiotherapy (RT) following chemotherapy (CT) failure in patients with Hodgkin's disease (HD) remains undefined. The aims of this study are: (1) to assess the pattern of failure, failure-free and overall survival, in patients who receive salvage RT for HD after CT failure; and (2) to identify patient subsets most suitable for this treatment approach. Materials and Methods: A review of patients treated between 1978 and 1992 at the Peter MacCallum Cancer Institute identified 52 patients with relapsed/refractory HD following CT who received RT with curative intent. Eligibility for this study required either biopsy confirmation of relapse/residual disease, or else clear clinical or radiological disease progression. Patient characteristics at diagnosis: median age 26, with 32% > 40 years old; M/ F 31/21; stage I-4, II-16, III-25, IV-7. Initial CT was MOPP- 31 patients, ABVD-1, both-16. A median 6 cycles of CT was given per regimen. Prior to salvage RT, 26/52 patients had received both MOPP and ABVD, either as sequential regimens, or as alternating or hybrid protocols. The response to initial CT was: CR-30, PR/SD-18, PD-4. Duration of initial CR was < 12 months in 8/30 patients. Salvage treatment consisted of radiotherapy to all known areas of disease. Doses ranged from 3600-4000 cGy. Results: Twenty three patients (45%) achieved CR. With a median follow-up of 70 months (range 4.8-166), actuarial median failure free survival (FFS) and overall survival (OS) are 22 months and 83 months respectively. Actuarial 5 year FFS and OS are 26% and 57% respectively. Patients with CR duration > 12 months following initial CT, only one CT regimen prior to salvage RT, and anatomically limited relapse had a significantly longer FFS. These factors, and age < 40 were associated with significantly longer OS. Only 6% of patients failed solely in the irradiated volume as first site of relapse, with the total in-field relapse of 30%.

    1995-01-01

    Purpose : Since February 1991, a prospective study for non-small cell lung cancer patients who underwent radical resection and had a risk factor of positive resection margin or regional lymph node metastasis has been conducted to evaluated the effect of MVP chemotherapy and radiotherapy on the pattern of failure, disease free and overall survival, and tolerance of combined treatment. Materials and Methods : Twenty nine patients were registered to this study until Sep. 1993 ; of these 26 received planned therapy. Within 3 weeks after radical resection, two cycles of MVP(Motomycin C 6 mg/m 2 , Vinblastin 6 mg/m 2 , Cisplatin 6 mg/m 2 ) chemotherapy was given with 4 weeks intervals. Radiotherapy (5040 cGy tumor bed dose and 900 cGy boost to high risk area) was started 3 to 4 weeks after chemotherapy. Results : One and two year overall survival rates were 76.5% and 8.6% respectively. Locoregional failure developed in 6 patients (23.1%) and distant failure in 9 patients(34.6%). Number of involved lymph nodes, resection margin positivity showed some correlation with failure pattern but T-stage and N-stage showed no statistical significance. The group of patients who received chemotherapy within 2 weeks postoperatively and radiotherapy within 70 days showed lower incidence of distant metastasis. Postoperative combined therapy were well tolerated without definite increase of complication rate, and compliance rate in this study was 90%. Conclusion : 1) MVP chemotherapy showed no effect on locoregional recurrence, ut appeared to decrease the distant metastasis rate and 2) combined treatments were well tolerated in all patients. 3) The group of patients who received chemotherapy within 2 weeks postoperatively and radiotherapy within 70 days showed lower incidence of distant metastasis. 4) Addition of chemotherapy to radiotherapy failed to increase the overall or disease free survival

    To assess the relationship between the timing of radiotherapy and the risk of local failure in patients with endometrioid-type endometrial cancer who had undergone surgery and adjuvant external pelvic radiotherapy (with or without brachytherapy), but not chemotherapy. One hundred and seventy seven patients were analyzed in this study. The median follow-up of the survivors was 72 months. Radiotherapy was delivered after a median time of 14.6 weeks from surgery and the median overall treatment time was 6.4 weeks. The tumor relapsed in 32 (18.1%) patients after a median time of 21 months. The local recurrence (vaginal or central pelvic) occurred in 11 patients. The local recurrence rate was associated with tumor grade (p=0.02), myometrial invasion (p=0.046), FIGO stage (p=0.003), pathological node status (p=0.037) and time interval from surgery to radiotherapy using 9 weeks as the cut-off value (p=0.046), but not with the overall treatment time. All the local relapses occurred in patients who received adjuvant irradiation after an interval from surgery >9 weeks. The time interval from surgery to radiotherapy might affect the local recurrence rate in patients not receiving chemotherapy. Every possible effort should be made to start radiotherapy within 9 weeks, when radiotherapy only is deemed necessary as adjuvant treatment.

    The therapy of the axillary lymph node in early breast cancer was assessed perspectively. Recently, axillary irradiation was carried out and compared with surgery. Radiotherapy was not evaluated more successful. To carry out in accordance with the present guide line, so called ''modern technique'' or ''modern dosage schedule'', radiotherapy of the axilla is effective as well as surgery. We have many agreements that the rate of incidence of complication associated with irradiation was decreased in accordance with ''modern technique''. It is reasonable to radiate additionally after the selection by the ''node sampling'' in the sense of decreasing unnecessary irradiation. But it is not sufficient in their reliability, it is hard to expect this method getting more popular than now. We cannot find any difference in the effect of the treatment itself between present dissection and radiotherapy. However we have many agreements that axillary dissection may give the information about n-stage, and the contribution to the suitable selection to the prognosis factor and adjuvant chemotherapy was not so less even in early cancer. Some early cancers (non-invasive carcinoma or micro carcinoma) will not need the axillary therapy. It is one of the options ''to combine mastectomy under local anesthesia and radiotherapy'' in close cooperation with the skilled radiologist. (K.H.) 120 refs

    We intended to decrease late CNS reaction after radical radiotherapy for an intracranial germinoma by using combined neoadjuvant chemotherapy and involved-field radiotherapy. The efficacy in terms of its acute toxicity and short-term relapse patterns was analyzed. Eighteen patients were treated with combined neoadjuvant chemotherapy and radiotherapy between 1995 and 2001. The chemotherapy regimen used was the Children's Cancer Group (CCG) 9921A (cisplatin, cyclophosphamide, VP-16, vincristine) for 5 patients younger than 16 years, BEP(bleomycin, VP-16, cisplatin) for 12 patients, and EP (VP-16, cisplatin) for 1 patient. The radiotherapy covered the whole craniospinal axis for 5 patients, the whole brain for 1, and the partial brain (involved field) for 12. the primary lesion received tumour doses between 3,960 and 5,400 cGy. The male to female ratio was 16:2 and the median age was 16 years old. The tumors were located in the pineal gland in 12 patients, in the suprasellar region in 1, in the basal ganglia in 1, in the thalamus in 1. Three patients had multiple lesions and ventricular seedings were shown at MRI. In 3 patients, tumor cells were detected in the cerebrospinal fluid and MRI detected a spinal seeding in 2 patients. The response to neoadjuvant chemotherapy was complete remission in 5 patients, partial remission in 12, and no response in 1. However, after radiotherapy, all except 1 patient experienced complete remission. The toxicity during or after chemotherapy greater than or equal to grade III was remarkable; hematologic toxicity was observed in 11 patients, liver toxicity in none, kidney toxicity in none, and gastrointestinal toxicity in one. One patient suffered from bleomycin-induced pneumonitis. Radiotherapy was therefore stopped and the patient eventually died of respiratory failure. The other 17 are alive without any evidence of disease or relapse during an average of 20 months follow-up. A high response rate and disease control was

    The article reviews the literature and gives an account of the authors' experience during a 20-year period (1960-1980) of the value of radiotherapy after surgery in the management of 76 patients suffering from brain gliomas classified into 3 grades according to the degree of anaplasia present in the histological sections, viz. grades II, III and IV. Radiotherapy was not given to grade I malignant gliomas as they are treated by surgery only. The period is divided into 2 subperiods. The first is from 1960-1972 when part-brain, high-dose irradiation following surgery was used on 33 patients in various age groups. The second period covers whole-brain, low-dose irradiation following surgery and was used on 43 patients in various age groups.

    Purpose: The role of radiotherapy in the management of patients with locoregional recurrent cervix cancer after radical surgery were retrospectively analyzed. Methods and materials: Twenty-eight patients treated with radiotherapy for locoregional recurrence after primary surgery for carcinoma of the cervix between 1989 and 1993 were analyzed. The median follow-up of survivors was 15 months (ranged 7-43 months). Eight patients had their disease confined to the vagina and 19 patients(68%) had pelvic mass as part of their locoregional recurrent disease. Within 24 months after the initial surgery, 82% of recurrences manifested themselves. All patients had whole pelvic irradiation with or without intracavitary radiotherapy(ICR). Results: Complete response(CR) was achieved in 18 patients(64%). Five of eighteen patients(28%) with initial CR developed second locoregional recurrence. Response to radiotherapy correlated strongly with tumor volume, site of recurrence and total radiation dose. The overall 2 year survival rate was 43% and the disease free survival was 31%. Survival rate was significantly influenced by the factors of interval from operation to recurrence, size and site of recurrent tumor, radiation dose, response of radiotherapy, lymph node status as initial presentation. The principal cause of death was lung metastasis(36%). Conclusion: Radiotherapy is an excellent modality for control of locoregional recurrent cervix cancer. To improve local control and survival rate, whole pelvic external radiotherapy in addition to ICR with more than 75.0Gy at the depth of 1.0cm from vaginal mucosa is needed and frequent follow up and early detection of recurrence is suggested as well

    To observe the effects of MVP chemotherapy combined with concurrent radiotherapy for stage IIIB-IV non-small cell lung cancer. Sixty-two patients with stage IIIB-IV non-small cell lung cancer were randomized into two groups, concurrent radiochemotherapy group and MVP che-motherapy group. All patients in two groups were treated with MVP regimen (mitomycin C 6 mg/m² on day 1, vindesine 2 mg/m² on days 1, 8, and cisplatin 80-100 mg/m²). Patients in concurrent radiochemotherapy group received concurrent radiotherapy (46-56 Gy in 5-6 weeks). All patients received 2-4 cycles of MVP chemotherapy. The response rate was 48.4% and 19.4% in concurrent radiochemotherapy group and MVP group respectively (P MVP group.. The results show that efficacy of MVP chemotherapy combined with concurrent radiotherapy is significantly higher than that of MVP chemotherapy alone for advanced non-small cell lung cancer.

    We conducted a phase II clinical trial of induction chemotherapy followed by surgery ± radiotherapy for squamous cell carcinoma of the oral tongue (SCCOT) in young adults. From September 2001 to October 2004, 23 patients aged 18 to 49 years with clinical T2-3 N0-2 M0 SCCOT and no prior radiotherapy, chemotherapy, or neck dissection underwent induction chemotherapy (paclitaxel, ifosfamide, and carboplatin) followed by glossectomy and neck dissection ± radiotherapy and chemotherapy. On final surgical pathology, 9 patients (39%) had a complete/major (2 complete) histologic response at the primary tumor site; 8 patients (35%) had no response or progression. Similarly, 9 patients (39%) had a complete response in the neck or remained node negative; 6 patients (26%) had an increase in nodal category. No treatment-associated deaths occurred, and toxicity was modest. At a median follow-up from the end of treatment of 52 months (minimum, 23 months), 10 patients (43%) developed recurrence, and all 10 died of cancer. Crude recurrence/cancer death rates were associated with ≤ a partial response at the tongue (p = .029), poor histologic differentiation (p = .012), and multiple adverse features on final surgical pathology (p = .040). Response rates and overall survival with this induction chemotherapy regimen were limited, but complete/major response at the tongue was associated with excellent prognosis. Additionally, improved patient selection and predictive tumor biomarkers will be needed for induction chemotherapy to be routinely incorporated into the treatment of oral tongue cancer in young adults.

    To evaluate the effect of MVP chemotherapy and hyperfractionated radiotherapy in Stage III unresectable non small cell lung cancer (NSCLC), authors have conducted a prospective randomized study since January 1991. Stage IIIa or IIIb unresectable NSCLC patients were treated with hyperfractionated radiotherapy (120 cGy/fx BID) up to 6500 cGY following 3 cycles of induction MVP (Mitomycin C 6 mg/m 2 , vinblastine 6 mg/m 2 , Cisplatin 60 mg/m 2 ) and randomized for either observation or 3 cycles of maintenance MVP chemotherapy. Until August 1991, 18 patients were registered to this study. 4 cases were stage IIIa and 14 were stage IIIb. Among 18 cases 2 were lost after 2 cycles of chemotherapy, and 16 were analyzed for this preliminary report. The response rate of induction chemotherapy was 62.5%; partial response, 50% and minimal response, 12.5%. Residual tumor of the one partial responder was completely disappeared after radiotherapy. Among 6 cases who were progressed during induction chemotherapy, 4 of them were also progressed after radiotherapy. All patients were tolerated BID radiotherapy without definite increase of acute complications, compared with conventional radiotherapy group. But at the time of this report, one patient expired in two month after the completion of the radiotherapy because of treatment related complication. Although the longer follow up is needed, authors are encouraged with higher response rate and acceptable toxicity of this treatment. Authors believe that this study is worthwhile to continue

    The coexistence of pregnancy and cancer is a challenging situation for the physician. Chemotherapy and radiotherapy are often necessary, depending on the type and stage of cancer at diagnosis. When applying such treatment, several key points concerning the health of the fetus must be carefully monitored. Meanwhile, if the appropriate treatment is delayed until postpartum, the mother's life may be at risk. Historically, the mother's health was placed above that of the fetus. This concept has changed, and harmonization of maternal and fetal health is now considered ideal. Numerous reports have shown the safe use of chemotherapy especially during the second and third trimesters of pregnancy. In 2004 our department treated seven cases of simultaneous cancer and pregnancy, leading us to review the use of chemotherapy and radiotherapy during pregnancy and the repercussions on neonatal outcome.

    It is well established that treatment modalities against cancer have psychosocial and serious medical side effects especially neurologic, learning, and intellectual disorders among children with cancer. The aim of this study was to evaluate the behavioral change specially the effect of chemotherapy and cranial radiotherapy on the development of attention deficit hyperactivity disorder (ADHD) in children with cancer. The children diagnosed with cancer and referred to Mahak Hospital (a well funded charity organization helping children with cancer in Iran) participated in this study. To assess the post treatment behavior, the Conner's Rating Scales (CRS) questionnaire, which its reliability and validity has been well established was administrated by trained interviewer in a two hour sessions to mother or attending nurses of the cases. The relationship between attention deficits, hyperactivity disorder were assessed with different categories of treatment, socio-economic status, age at diagnosis, sex, as well as duration since treatment. During periods of six months, 30 subjects (16 male and 14 female) were studied and participated in the study. Fifteen cases had both radiotherapy as well as chemotherapy and 15 cases just had chemotherapy as their treatment regiment. The mean Conner's Rating Score (total score of ADHD) were higher among those who received both chemotherapy and radiotherapy compared with those who had just chemotherapy but it was not statistically significant (34.7∓12.6 for just chemotherapy and 39.3∓9.0 for chemo and radiotherapy together). The total Conner's Rating Score was higher among girls compared to boys (mean ∓ standard deviation was 39.8∓9.4 for girls and 33.7∓12 for boys). Duration since treatment, age diagnosis, and mother's level of education had effect in post treatment intellectual capacity and behavioral aspect of patients. In the light of dramatic improvement of survival among children with cancer the intellectual and

    Full Text Available Purpose. Conservative treatment in the form of limited surgery and post-operative radiotherapy is controversial in hand and foot sarcomas, both due to poor radiation tolerance of the palm and sole, and due to technical difficulties in achieving adequate margins.This paper describes the local control and survival of 41 patients with soft tissue sarcoma of the hand or foot treated with conservative surgery and radiotherapy. The acute and late toxicity of megavoltage radiotherapy to the hand and foot are described. The technical issues and details of treatment delivery are discussed. The factors influencing local control after radiotherapy are analysed.

    Increased incidence of acute leukaemia (AL) following exposure to ionizing radiation is well documented. AL has also been reported with increased frequency after chemotherapy for nonmalignant diseases. The effect of chemotherapy and/or radiotherapy on the following erythrocyte parameters: pyruvate-kinase (PK) activity, phospho-fructo-kinase (PFK) activity, HbF level, red cell antigens production and bone marrow sideroblasts, has been studied in 31 patients with myelomatosis and in 33 patients with nonhaematological malignancies. We have demonstrated the apperance after chemotherapy or radiotherapy of some abnormalities usually associated with leukaemia or preleukaemic states. In patients treated for myelomatosis, a PK deficiency has been detected in 58 % of the cases, an increased HbF level in 47 %, a modification of blood groups antigens in 68 % and abnormal sideroblasts in 30 %. No PFK deficiency was found. In patients treated for solid tumors, a PK deficiency in 50 % of the cases, a PFK deficiency in 20 %, an increased HbF level in 10 %, a modification of blood group antigens in 40 % has been detected. Chemotherapy administered over a period of 3 months has been shown to induce these abnormalities. Localized radiotherapy may have a similar effect. The combination of these two factors seems to cause an increase in the frequency and intensity of these abnormalities. (author)

    Polymorphic reticulosis has recently been characterized as an angiocentric lymphoproliferative disorder of the peripheral T-lymphocytes. However, its treatment is still a matter of controversy. In order to study efficacy and toxicity of the primary treatment, we reviewed clinical features and therapeutic results in 29 patients seen at the Instituto Nacional de Cancerologia de Mexico. Nineteen patients received primary local irradiation and 10 patients primary combination chemotherapy. In the radiotherapy group, 14 (74%) patients achieved complete response, but only 4 (40%) did so in the primary chemotherapy group. Five patients in the latter group died of treatment-related complications. The 5-year actuarial survival rate was 70% in the irradiation group, while the 1-year survival rate was only 15% in the chemotherapy group. These data strongly suggest that, in polymorphic reticulosis, initial chemotherapy may be very toxic. (orig.)

    Twenty-five patients with advanced laryngeal cancer were treated with twice-a-day fractionated radiotherapy (TDFR) to a total dose of 65 Gy to 82 Gy combined with chemotherapy of CDDP and 5-FU between 1994 and 1997. Twenty-two cases (88%) became complete response and 9 cases recurred. The relapse-free rate at 2 years was 49.8%. The laryngeal conserving rate at 2 years was 71.0%, the actuarial 2-year survival rate was 89.9%. In induction chemotherapy (12 cases) no severe toxicity has been observed. In TDFR with concurrent chemotherapy (22 cases), grade 3 hematological toxicity was observed in 4 cases and grade 4 mucosal toxicity in 16 cases. Based on this investigation, it is concluded that TDFR with chemotherapy is a promising modality for advanced laryngeal cancer and toxicity is acceptable. (author)

    Neuropsychological tests were used to evaluate possible central nervous system dysfunction in patients treated with chemotherapy. Ninety-five patients with non-small cell lung cancer limited disease were randomized to either radiotherapy (2.8 Gyx15) or combination chemotherapy with cisplatin and etoposide. In order to evaluate cognitive functions three neuropsychological tests were applied: Trail Making, Benton Visual Retention Test and Verbal Learning. Changes in the patients' test scores before and after treatment were compared. The chemotherapy patients showed reduced performance on some of the neuropsychological tests compared to the radiotherapy group. This indicates a treatment related effect on the central nervous system, possibly caused by the combination chemotherapy.

    Combined chemo- and radiotherapy are established in breast cancer treatment. Chemotherapy is recommended prior to radiotherapy but decisive data on the optimal sequence are rare. This retrospective analysis aimed to assess the role of sequencing in patients after mastectomy because of advanced locoregional disease. A total of 212 eligible patients had a stage III breast cancer and had adjuvant chemotherapy and radiotherapy after mastectomy and axillary dissection between 1996 and 2004. According to concerted multi-modality treatment strategies 86 patients were treated sequentially (chemotherapy followed by radiotherapy) (SEQgroup), 70 patients had a sandwich treatment (SW-group) and 56 patients had simultaneous chemoradiation (SIM-group) during that time period. Radiotherapy comprised the thoracic wall and/or regional lymph nodes. The total dose was 45–50.4 Gray. As simultaneous chemoradiation CMF was given in 95.4% of patients while in sequential or sandwich application in 86% and 87.1% of patients an anthracycline-based chemotherapy was given. Concerning the parameters nodal involvement, lymphovascular invasion, extracapsular spread and extension of the irradiated region the three treatment groups were significantly imbalanced. The other parameters, e.g. age, pathological tumor stage, grading and receptor status were homogeneously distributed. Looking on those two groups with an equally effective chemotherapy (EC, FEC), the SEQ- and SW-group, the sole imbalance was the extension of LVI (57.1 vs. 25.6%, p < 0.0001). 5-year overall- and disease free survival were 53.2%/56%, 38.1%/32% and 64.2%/50%, for the sequential, sandwich and simultaneous regime, respectively, which differed significantly in the univariate analysis (p = 0.04 and p = 0.03, log-rank test). Also the 5-year locoregional or distant recurrence free survival showed no significant differences according to the sequence of chemo- and radiotherapy. In the multivariate analyses the sequence had no

    Neoadjuvant therapy plays an important role for organ preservation and survival rate in the treatment of oral cancer. We clinically compared the effect of neoadjuvant radiotherapy and chemoradiotherapy in patients with oral cancer. We retrospectively examined 47 patients diagnosed with oral squamous cell carcinoma who underwent neoadjuvant therapy followed by curative surgery in the oral and maxillofacial surgery department of Ehime University Hospital. We divided them into two groups: radiotherapy alone (24 cases) and chemoradiotherapy (23 cases). The patients in the radiotherapy group underwent irradiation of 32.6{+-}5.0 Gy (mean {+-}SD). The patients in the chemoradiotherapy group received a low-dose fraction of cisplatin (8 mg/mm{sup 2}/day, 5 days a week; total dose: 139.4{+-}67.1 mg) and 5-fluorouracil (300 mg/mm{sup 2}/day, 5 days a week; total dose: 5,900{+-}1,839.8 mg) combined with simultaneous irradiation of 31.0{+-}3.2 Gy. None of the 24 patients had a complete response to radiotherapy alone and 12 (50%) had a partial response. Six (26%) of the 23 patients had a complete response to chemoradiotherapy and 12 (52%) had a partial response. The primary control rate (82.6%) to chemoradiotherapy was higher than that (67.5%) to radiotherapy alone although no significant difference was found. The 5-year survival rate was 64.3% in the radiotherapy group and 62.8% in the chemoradiotherapy group. The findings of the present study suggest that while the combination of radiation and cisplatin/5-fluorouracil in neoadjuvant therapy for oral cancer may not bring a significant benefit to improve survival rate, the primary local control rate is improved in comparison with radiotherapy alone.

    This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy.

    The hematologic immediate toxicity during radiotherapy for Hodgkin's disease was studied from a series of 72 patients who received 3 courses or more of chemotherapy before radiotherapy. The toxicity in the group of 36 of them who received total nodal irradiation (TNI) was the most important. Sixteen of the 28 TNI had irradiation interrupted, 12 of them began with inverted Y type. The blood cells count at the beginning of the treatment was crucial; only 16% of the patients had interruption of irradiation when the blood cells count was normal; on the other side, 63% had interruption when the blood cells count was abnormal (P [fr

    The effects of an association of chemotherapy and radiotherapy on the skin of mice were studied. The following drugs were tested; hydroxyurea, Methotrexate, and Bleomycin; they were injected at various times before irradiation. When hydroxyurea was injected 15 min before irradiation, the early and late cutaneous reactions were significantly lower than with irradiation alone. This protective effect corresponds to about 500 rad for an irradiation dose of 2500 rad. In the other protocols, we observed either no increase of the effect as a result of adjuvant chemotherapy (Methotrexate) or slightly increased reactions

    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

  14. The search for therapeutic gain in the combination of radiotherapy and chemotherapy

    1988-01-01

    The literature on combined treatment with radiation and cytotoxic drugs in experimental tumours and normal tissues of laboratory animals is reviewed in the context of the four previously proposed mechanisms whereby a therapeutic advantage might be gained. There is evidence for strong time-dependent processes occurring in some normal tissues. In tumours, the evidence is much weaker and there is considerable disparity among experimental tumours in optimum timing. This review leads to the conclusion that the clinical use of drug-radiation combinations should not be based on an anticipated beneficial interaction; gain will most probably come from the best radiotherapy and the best chemotherapy given as far as possible independently. Deleterious interactions can be reduced by allowing a gap of some weeks between chemotherapy and radiotherapy and by avoiding drugs that are known to enhance radiation damage to the normal tissues that are irradiated. 131 refs.; 4 figs.; 5 tabs

    The oral mucositis is a frequent and potentially severe complication of the antineoplasic therapy; it is considered that approximately 400.000 new patients per year in United States will develop acute or chronic complications in oral cavity after the beginning of its treatment. Some of the basic manifestations that are inside the clinical descriptions understand the erythema, the desquamation, formation of ulcers, the bled, and exudation. The epithelial oropharynge surface has a quick replication rate, and for this reason it is highly exposed to the direct insult due to the cytotoxic effects of the chemotherapy, the radiotherapy, and indirectly the infectious agents. The paper includes topics like physiopathology, risk factors, chemotherapy, radiotherapy, the patient's evaluation and conclusions

    Purpose: To evaluate the long-term results of salvage radiotherapy (SRT) for Hodgkin's lymphoma after chemotherapy failure. Methods and Materials: We reviewed 81 patients undergoing SRT for persistent or recurrent Hodgkin's lymphoma after chemotherapy; 19 also received conventional-dose salvage chemotherapy. Results: At SRT, the median patient age was 31 years. Of the 81 patients, 81% had Stage I-II, 25.9% had B symptoms, 14.8% had bulky disease, and 7.4% had extranodal disease. A less than a complete response (CR) to the last chemotherapy regimen occurred in 47%. SRT was generally limited to one side of the diaphragm, and the median dose was 36 Gy. After SRT, 75% of patients achieved a CR, with 82% retaining durable in-field control. In-field failure was associated with less than a CR to the last chemotherapy regimen (p = 0.0287). Most failures were at distant sites, with 60% in previously involved sites. The 10-year freedom from treatment failure and overall survival rates were 32.8% and 45.7%, respectively. The adverse prognostic factors for freedom from treatment failure were age >50 years (p 50 years (p < 0.001), B symptoms (p = 0.002), and less than a CR to the last chemotherapy regimen (p = 0.002). Favorable cohorts had a 10-year freedom from treatment failure rate of 51% and overall survival rate of 92%. Conclusions: Salvage radiotherapy is effective for selected patients with Hodgkin's lymphoma after chemotherapy failure and should be considered for incorporation into salvage programs

    The possible importance of the immune system in early development and progression of breast cancer is being discussed. The different laboratory methods in controlling the specific and non-specific immune reactivity are summarized. The modification of the immunological parameters by radio- resp. chemotherapy is critically presented on the basis of published data and on own results. An analysis of the data obtained by various immunological methods in respect to their consequences in diagnosis and prognosis is done. An immunological monitoring in the control of radio-, chemo- and immunotherapy in breast cancer patients is proposed. (orig.) [de

    A total of 9 patients with invasive bladder cancer (T2b, n=2; T3a, n=0; T3b, n=3; T4, n=4) were treated with intra-arterial cisplatin (CDDP) and pirarubicin (THP)-doxorubicin (ADM), in combination with external radiotherapy. Clinical response was as follows: complete response (CR) was obtained in 3 patients, partial response (PR) in 2 patients, no change (NC) in 3 patients and no progressive disease (PD). One patient died during the treatment because of pneumonia caused by myelosuppression and overall response rate was 62.5%. Total cystectomy was performed for 4 patients after chemo-radiotherapy. Overall survival rate was 75.0% for 1-year, 62.5% for 2-year, and 41.7% for 5-year. In group with cystectomy survival rate was 100% for 1-year, 100% for 2-year, and 50.0% for 5-year. In group without cystectomy, 50.0% for 1-year, and 25.0% for 2-year. Overall no recurrence rate was 87.5% for 6-months, 58.3% for 1-year, and 58.3% for 5-year. Main side effects were myelosuppression, appetite loss, diarrhea, thigh pain and contracted bladder. (author)

    The eye has traditionally been regarded as a sanctuary site for drugs, but recent publications have shown evidence of penetration by drugs and subsequent clinical response of intraocular lymphomas. In this report, a chemotherapy regimen, including high dose methotrexate and cytosine arabinoside, was used to re-induce remission in a patient with intraocular lymphoma relapsing locally after prior radiotherapy. She remains disease free 18 months later. (author).

    The combination of radiotherapy and chemotherapy has improved the results of treatment of certain malignant tumours. However, during both experimental investigations and clinical treatment, a number of severe side effects have been observed, during as well as some time after the administration, especially with use of actinomycin and adriamycin. Also the possibility exists that more secondary tumours are induced as the consequence of combination therapy. (Auth.)

    Full text of publication follows: purpose: to describe outcome of patients with muscle-invasive bladder carcinoma treated with multimodality therapy in our institution from 1993 to 2002. Patients and methods: the charts of sixty patients with T2-4, N0-1, M0 treated with TURBT followed by a chemo-radiotherapy combination were retrospectively reviewed: 22 received neo-adjuvant chemotherapy (CMV/MVAC) followed by concomitant chemo-radiotherapy (weakly cisplatin/carbo-platin or a cisplatin and 5-fluorouracil association) and the other 38 concomitant chemo-radiotherapy alone. Radiotherapy delivered a median dose of 45 Gy to the pelvis and 65 Gy to the bladder in a mono-fractionated or twice a day fractionation scheme. Follow-up evaluations included cystoscopy with biopsies at regular intervals. Salvage cystectomy was recommended in case of local persistent tumor or bladder relapse. Results: median follow-up was 48.5 months (10-126 months). 82% (18/22) of the patients receiving neo-adjuvant chemotherapy had 2 or more cycles and 85% (51/60) got the concomitant chemotherapy as planned. Radiotherapy was completed in 56 patients. Twenty-eight patients relapsed either locally (14 did not achieve local complete response after chemo-radiation and 6 had true local relapse during follow-up) or at distant sites. Actuarial 5-year disease-specific survival and freedom from local and distant relapse rate are respectively 54% and 42%. Actuarial local control rate with intact bladder was 56% at 5-year. When separated according to stage and grade, patients with T2/3 grade 2 tumors had significantly better chance of remaining relapse-free than the others (p = 0.045). Salvage cystectomy (n = 11) for isolated local failure in this population achieved limited results. Conclusion: our experience shows that a significant number of patients will achieve long survival with their bladder intact after multimodality therapy. (authors)

    As part of a study on hematopoietic effects of A-bombing, a nationwide questionnaire survey was made in 1,487 facilities to analyze secondary leukemia. A total of 232 patients, who were reported to have developed secondary hematopoietic or solid tumor, were eligible for this study. For 62 each evaluable male and female patients, the most common primary solid cancer was gastric cancer (27/62) for men; and breast cancer (25/62) and urinary cancer (27/62) for women. Of a total of 124 patients, 73 (59%) developed acute leukemia as secondary hematopoietic tumor, 53 of whom had underwent chemotherapy and/or radiotherapy for primary cancer. For primary hematopoietic tumor seen in 90 patients, non-Hodgkin's disease was the most common (38%, 34/90), followed by multiple myeloma (20%, 18/90). Of a total of 155 patients developing secondary hematopoietic tumor, 111 had received chemotherapy and/or radiotherapy. Chemotherapy or radiotherapy for primary cancer may have the potential risk for developing secondary cancer. (N.K.)

    Recommended treatment for lymphoblastic lymphomas, a highly aggressive, relatively rare lymphoma entity predominantly seen in teenagers and young adults, includes acute lymphoblastic leukemia (ALL)-like induction chemotherapy. Whether these patients should be consolidated with maintenance chemotherapy or autologous stem cell transplantation (Auto-SCT) and the use of radiotherapy are matters of debate. We reviewed treatment and outcome for 25 consecutive patients above the age of 15 years with lymphoblastic lymphoma (T-lineage; T-LBL, n = 19; B-lineage; B-LBL, n = 6) seen at a single center during a 12-year period (1999-2011). Patients were given an ALL-like chemotherapy induction regimen, and responding patients were consolidated with Auto-SCT and local radiotherapy when applicable. Median age at diagnosis was 33 years (range 15-65). Seventeen of the T-LBL patients had a mediastinal mass, three patients had central nervous system (CNS) involvement. Chemotherapy with intensified CNS prophylaxis induced an overall response rate of 92% (CR 84%, PR 8%). In total 23/25 (92%) patients underwent Auto-SCT in first remission while 13 of 14 eligible patients with mediastinal involvement received local radiotherapy. Twenty percent of the patients had hepatotoxicity grade 3-4 and 32% thromboembolic events (TE). Two patients (8%) died of treatment-related toxicity. One patient had progressive disease and died of lymphoma. Three patients have relapsed, but two of these (both B-LBL) are currently alive in second CR after Allo-SCT. With a median follow-up of 98 months (range 1-163) the 5- and 8-year PFS and OS are 76% and 84%, respectively. Combined intensive ALL-like induction and early consolidation chemotherapy followed by Auto-SCT and local radiation therapy resulted in high sustained cure rates.

    During the past 23 years, from June 1989 to December 2012, our treatment paradigm for head and neck squamous cell carcinoma (HNSCC) had involved comprehensive use of chemotherapy and radiation therapy followed by surgery. Between 1989 and 2005, chemotherapy using fluorouracil and carboplatin had been administered via intravenous drip infusion as induction chemotherapy (ICT), and more recently between 2006 and 2012 as concurrent chemoradiotherapy (CCRT). In the present study, we examined the superiority of definitive CCRT (dCCRT) over the ICT followed by definitive radiotherapy (ICT-dRT) as to the impact on the treatment of HNSCC with the stage-categories of T2-T4a, retrospectively analyzing survival rates and laryngeal preservation rates at the 3-year point between the two groups. The number of patients assigned for this study was 76, all of whom were previously untreated, and of whom 51 suffered from laryngeal carcinoma and 25 from hypopharyngeal carcinoma: 21 with Stage II, 25 with Stage III, 23 with Stage IV A, 7 with Stage IV C. The three-year overall survival rate and cause-specific survival rate were 54.5%, 73.5% in the ICT-dRT group and 69.2%, 80.5% in the dCCRT group, respectively, both of which statistically had no difference. But the dCCRT was found to contribute to obtaining a higher rate of laryngeal preservation than that of the ICT-dRT in T2 and T3 but not in T4a. In conclusion, dCCRT showed more significant efficacy for organ preservation on T2 and T3 HNSCC than ICT-dRT. (author)

    Background: Nicotinamide and carbogen have been shown to enhance the radiation effect in tumour models. Purpose: Prospective evaluation of the toxicity and efficacy of carbogen and nicotinamide with external beam radiotherapy in the management of inoperable glioblastoma. Patients and methods: From April 1995 to December 1997, 33 patients with inoperable biopsy-proven glioblastoma multiforme (GBM) were enrolled in a phase II trial, to undergo radiotherapy (59.4 Gy in 1.8 Gy/fraction), intra-arterial cerebral chemotherapy (ACNU 100 mg/m 2 , three cycles), carbogen breathing (15 l/min), and nicotinamide (85 mg/kg). This experimental group was compared to a control group of 38 patients with inoperable GBM treated with radiotherapy and three cycles of nitrosourea-based chemotherapy from January 1990 to March 1995, in our institution. Results: In the experimental group, carbogen breathing was well tolerated, but only 51.5% of patients completed daily nicotinamide over the 6.5-week treatment period. Nausea and vomiting were the most frequent side effects of nicotinamide. No significant difference in overall survival was observed among the two treatment groups: median survival times were 36.7 and 35.3 weeks for patients treated with carbogen and nicotinamide, and for those treated in the control group, respectively. Conclusion: The association of carbogen and nicotinamide with radiotherapy is feasible, but tolerable only in 51.5% of patients with GBM. Carbogen and nicotinamide did not appear to modify the evolution of glioblastoma

    Purpose: To analyze the recent single-institution experience of patients with salivary gland tumors who had undergone adjuvant intensity-modulated radiotherapy (IMRT), with or without concurrent chemotherapy. Patients and Methods: We performed a retrospective analysis of 35 salivary gland carcinoma patients treated primarily at the Dana-Farber Cancer Institute between 2005 and 2010 with surgery and adjuvant IMRT. The primary endpoints were local control, progression-free survival, and overall survival. The secondary endpoints were acute and chronic toxicity. The median follow-up was 2.3 years (interquartile range, 1.2-2.8) among the surviving patients. Results: The histologic types included adenoid cystic carcinoma in 15 (43%), mucoepidermoid carcinoma in 6 (17%), adenocarcinoma in 3 (9%), acinic cell carcinoma in 3 (9%), and other in 8 (23%). The primary sites were the parotid gland in 17 (49%), submandibular glands in 6 (17%), tongue in 4 (11%), palate in 4 (11%), and other in 4 (11%). The median radiation dose was 66 Gy, and 22 patients (63%) received CRT. The most common chemotherapy regimen was carboplatin and paclitaxel (n = 14, 64%). A trend was seen for patients undergoing CRT to have more adverse prognostic factors, including Stage T3-T4 disease (CRT, n = 12, 55% vs. n = 4, 31%, p = .29), nodal positivity (CRT, n = 8, 36% vs. n = 1, 8%, p = .10), and positive margins (n = 13, 59% vs. n = 5, 38%, p = .30). One patient who had undergone CRT developed an in-field recurrence, resulting in an overall actuarial 3-year local control rate of 92%. Five patients (14%) developed distant metastases (1 who had undergone IMRT only and 4 who had undergone CRT). Acute Grade 3 mucositis, esophagitis, and dermatitis occurred in 8%, 8%, and 8% (1 each) of IMRT patients and in 18%, 5%, and 14% (4, 1, and 3 patients) of the CRT group, respectively. No acute Grade 4 toxicity occurred. The most common late toxicity was Grade 1 xerostomia (n = 8, 23%). Conclusions: Treatment of

    Full Text Available Abstract Background Despite broad advances in multimodal treatment of locally advanced breast cancer (LABC, 30 to 40% of patients develop loco-regional relapse. The aim of this study was to analyze in a retrospective manner the effectiveness of concurrent chemo-radiotherapy (CCRTh after neoadjuvant chemotherapy (NCT in patients with LABC. Methods One hundred twelve patients with LABC (stage IIB-IIIB were treated with NCT (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2 (FAC, or doxorubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 (AC IV in four 21-day courses followed by CCRTh (60 Gy breast irradiation and weekly mitomycin 5 mg/m2, 5-fluorouracil 500 mg/m2, and dexamethasone 16 mg, or cisplatin 30 mg/m2, gemcitabine 100 mg/m2 and dexamethasone 16 mg, and 6–8 weeks later, surgery and two additional courses of FAC, AC, or paclitaxel 90 mg/m2 weekly for 12 weeks, and in case of estrogen-receptor positive patients, hormonal therapy. Results Stages IIB, IIIA and -B were 21.4, 42.9, and 35.7%, respectively. Pathological complete response (pCR in the breast was 42% (95% CI, 33.2–50.5% and, 29.5% (95% CI, 21.4–37.5% if including both the breast and the axillary nodes. Multivariate analysis showed that the main determinant of pCR was negative estrogen-receptor status (HR = 3.8; 95% CI, 1.5–9; p = 0.016. The 5-year disease-free survival (DFS was 76.9% (95% CI, 68.2–84.7%. No relationship between pCR and DFS was found. Multivariate analysis demonstrated that the main DFS determinant was clinical stage (IIB and IIIA vs. IIIB, HR = 3.1; 95% CI, 1.02–9.74; p = 0.04. Only one patient had local recurrence. Five-year overall survival was 84.2% (95% CI, 75–93.2%. The toxicity profile was acceptable. Conclusion This non-conventional multimodal treatment has good loco-regional control for LABC. Randomized clinical trials of preoperative CCRTh following chemotherapy, in patients with LABC are warranted.

    Research on anticancer therapies has advanced significantly in recent years. New therapeutic platforms that can further improve the health of patients are still highly demanded. We propose the idea of combining regular chemotherapy with radiation therapy to minimize side effects as well as increase drug-delivery efficiency. In this Focus Review, we seek to provide an overview of recent advances that can combine chemotherapy and radiotherapy. We begin by reviewing the current state of systems that can combine chemotherapy and gamma radiation. Among them, diselenide-containing polymers are highlighted as sensitive drug-delivery vehicles that can disassemble under gamma radiation. Then X-ray responsive materials as promising alternative systems are summarized, including X-ray responsive drug-delivery vehicles, prodrugs that can be activated by X-rays, and radiation-site-targeting systems. Finally, we describe strategies that involve phototherapies. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available Introduction. Anaplastic thyroid carcinoma (ATC is rare yet accounts for up to 50% of all thyroid cancer deaths. This study reviews outcomes of patients with confirmed ATC referred to a tertiary oncology centre plus reviews the literature to explore how poor outcomes may be improved. Materials and Methods. The management and outcomes of 20 patients with ATC were reviewed. Results. Median age at diagnosis was 69.5 years. 19 patients died due to ATC, 40% of whom died from asphyxiation. Median survival for all cases was 59 days. Patients who had previous surgery prior to other treatment modalities had a longer median survival overall compared to those who had not had previous surgery (142 days compared to 59 days and produced the one long-term survivor. Chemotherapy followed by radiotherapy (without previous surgery was associated with longer median survival (220 days. Palliative radiotherapy alone did not decrease the rate of death by asphyxiation when compared to other single modality treatments. Conclusion. Multimodality treatment including surgery when feasible remains the best strategy to improve survival and prevent death from asphyxiation in the management of ATC. The addition of chemotherapy to our institutional protocol led to improved survival but prognosis remains very poor.

    The discussion on the role of adjuvant chemotherapy for rectal cancer patients treated according to current guidelines is still ongoing. A multicentre, randomized phase III trial, PROCTOR-SCRIPT, was conducted to compare adjuvant chemotherapy with observation for rectal cancer patients treated with preoperative (chemo)radiotherapy and total mesorectal excision (TME). The PROCTOR-SCRIPT trial recruited patients from 52 hospitals. Patients with histologically proven stage II or III rectal adenocarcinoma were randomly assigned (1:1) to observation or adjuvant chemotherapy after preoperative (chemo)radiotherapy and TME. Radiotherapy consisted of 5 × 5 Gy. Chemoradiotherapy consisted of 25 × 1.8-2 Gy combined with 5-FU-based chemotherapy. Adjuvant chemotherapy consisted of 5-FU/LV (PROCTOR) or eight courses capecitabine (SCRIPT). Randomization was based on permuted blocks of six, stratified according to centre, residual tumour, time between last irradiation and surgery, and preoperative treatment. The primary end point was overall survival. Of 470 enrolled patients, 437 were eligible. The trial closed prematurely because of slow patient accrual. Patients were randomly assigned to observation (n = 221) or adjuvant chemotherapy (n = 216). After a median follow-up of 5.0 years, 5-year overall survival was 79.2% in the observation group and 80.4% in the chemotherapy group [hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.62-1.39; P = 0.73]. The HR for disease-free survival was 0.80 (95% CI 0.60-1.07; P = 0.13). Five-year cumulative incidence for locoregional recurrences was 7.8% in both groups. Five-year cumulative incidence for distant recurrences was 38.5% and 34.7%, respectively (P = 0.39). The PROCTOR-SCRIPT trial could not demonstrate a significant benefit of adjuvant chemotherapy with fluoropyrimidine monotherapy after preoperative (chemo)radiotherapy and TME on overall survival, disease-free survival, and recurrence rate. However, this trial did not complete

Within the nationwide registry of the Danish Breast Cancer Group (DBCG), we identified 1798 patients who received adjuvant chemotherapy following mastectomy, lumpectomy or oncoplastic breast surgery for early...... and unilateral invasive breast cancer. Women treated with neoadjuvant chemotherapy were excluded. RESULTS: We found no significant difference between the three groups (mastectomy, lumpectomy, oncoplastic breast surgery) in the time from biopsy to surgery (mean time 17.9, 17.0 and 18.3 days, respectively...

  14. Immunological factors correlated in radiation effect in cancer patients treated by radiotherapy alone or radiotherapy with combined chemotherapy

    Local immunological factors are thought to be parenchymal reaction of normal and tumor tissues. Those were studied by morphological changes of angiographic findings and histological methods which included photomicroscopic, electromicroscopic and enzymic-histochemical studies. It was demonstrated that the effect of radiotherapy depended on not only local blood supply but also parenchymal reaction of the host. Especially, the parenchymal reaction at 2000 or 3000 rad irradiation was regarded as nonspecific tissue repair as well as immunological protective reactions brought about by enhancement of the tumor antigenicity. It was proved that T-cell system played a main role in this parenchymal reaction. Changes of systemic immunological factors were studied in 17 laryngeal cancer and 80 lung cancer patients treated by radiotherapy alone or radiotherapy with combined chemotherapy. Due to the fact that damages of the host before treatment were not so serious and integral dose given to the patients was a little in cases of laryngeal cancer immunological parameters such as absolute lymphocyte counts, PHA and PPD skin test activities, lymphocyte blastoid transformation with PHA, PWM and Con A, did not show significant change. However, as for lung cancer treated by large integral dose irradiation combined with chemotherapy, immunological parameters were depressed in inverse proportion to the dose of irradiation and chemotherapeutic agents. Moreover T-cell subsets (early E-rosette forming cells, IgG Fc-receptor positive cells), lymphocyte sub-populations, ADCC activity, serum immunoglobulins, and serum protein were also investigated in cases of lung cancer. We have evaluated the immunological parameters in relation to the therapeutic effect. As a result, it was suggested that several parameters should be needed to forecast the prognosis. (author)

    From April 1989 to January 1990, nine patients with locally advanced stage IV squamous cell carcinoma of the head and neck underwent combined chemotherapy and radiotherapy (RT). Chemotherapy consisted of two cycles of CDDP (100 mg/m 2 , day 1) + 5-FU (1 g/m 2 , days 1-5, continuous infusion) every five weeks. RT was interdigitated with chemotherapy after the second course of chemotherapy. Each course was initiated two or three days after interrupting chemotherapy. RT was delivered at 65 or 70 Gy for 8 weeks. Of the 7 patients completing the treatment, 29% responded totally, and 43% responded partially. Seven patients died: two due to acute treatment-related toxicity; four due to locoregional progression; and one due to an unrelated cause. Two patients are still alive (10 and 12 months); one is free of tumor, the other has a metastatic bone tumor. Though sequential use of CT might be considered effective for some patients, acute toxicity was moderate to severe and patients with poor performance (≤70%), elderly (≥70 yr) and renal dysfunction (creatinine clearance<80 ml/min) patients must be considered as high risk for treatment by our combined regimen.

    1996-01-01

    Purpose: This single-institution Phase I/II study conducted from 1989 to 1995 evaluates the feasibility of a multi-modality protocol combining hyperfractionated craniospinal radiotherapy (HFRT) followed by adjuvant chemotherapy in 23 patients with newly diagnosed primitive neuroectodermal tumors (PNET) arising in the central nervous system. Methods and Materials: All 23 patients had a histologically confirmed PNET and were over 3 years of age at diagnosis. The eligibility criteria for PNET patients with cerebellar primaries (medulloblastoma) included either a high T stage (T3b or 4) or high M stage (M1-3). All patients with noncerebellar primaries were eligible regardless of T or M stage. The median age of the 23 patients was 9 years (mean 3-25); 11 were female. The primary tumor arose in the cerebellum in 19. Of these medulloblastoma patients, 15 had high T stages (T3b or T4) with large locally invasive tumors and no evidence of metastases (M0), constituting Group 1. Thirteen (86%) of these patients had gross total resections. Four other medulloblastoma patients had both high T and high M stages, constituting Group 2. Group 3 consisted of four other patients with exocerebellar primaries (two brain, one brain stem, and one cauda equina), three of whom were M3. Hyperfractionated radiotherapy was administered within 4 weeks of surgery. Twice-daily 1-Gy fractions were administered separated by 4-6 h. The total dose to the primary intracranial tumor and other areas of measurable intracranial disease was 72 Gy. The prophylactic craniospinal axis dose was 36 Gy, and boosts of 44-56 Gy were administered to metastatic spinal deposits. Following radiotherapy, monthly courses of multiagent chemotherapy were administered sequentially (cyclophosphamide-vincristine followed by cisplatin-etoposide followed by carboplatin-vincristine) for a total of 9 months. Results: All patients completed radiotherapy as planned. Only three patients lost >10% of their body weight. One patient

    Recent literature on chemoradiotherapy for esophageal cancer report the comparable survival results as surgery, and suggest the importance of management for the late adverse effect of chemoradiotherapy. The aim of this study is to investigate the incidence and risk factors of cardiomegaly after chemoradiotherapy using low dose continuous infusion of 5FU/CDDP+5FU for esophageal cancer. Fifty-one patients with stage I-IVA esophageal cancer who were treated by radiotherapy with more than 50 Gy with or without chemotherapy and followed up for more than 6 months were analyzed. Sixteen patients were treated by radiation alone and 35 patients were treated by chemoradiotherapy. A change of CTR (cardio-thoracic ratio) was defined as the difference between CTR in the pre-treatment X-ray film and CTR in the post-treatment X-ray film with maximum cardiac silhouette. A change of CTR by more than 10% was defined as ''significant cardiomegaly''. In this study cardiac area-dose'', which is the sum of the products of cardiac area within every radiation field and its target dose, was calculated in each patient as a radiation parameter. Significant cardiomegaly was noted in 1 patient (6%) in the radiation alone group, in 8 patients (23%) in the chemoradiotherapy group and in 9 patients (18%) in the total population. In cases with more than 0.4 m{sup 2}{center_dot}Gy in cardiac area-dose, CTR elevation was significantly higher than in cases with less than 0.4m{sup 2}{center_dot}Gy. More than moderate pleural effusion was noted in 5 patients (10%). Chronic pericardial effusion and subsequent cardiac tamponade was considered to be one of the contributing factors for pleural effusion, because increases of pleural effusion coincided with CTR elevations in 3 cases. In addition, the fact that no case had right-sided unilateral pleural effusion suggested the direct effect of radiation to the pleura. Significant cardiomegaly was seen in 18% of 51 patients with

    . Chemoradiotherapy consisted of 45 Gy in 25 fractions of 1·8 Gy, for 5 weeks, five daily fractions per week, combined with capecitabine (575 mg/m 2 orally twice daily on radiotherapy days) and cisplatin (20 mg/m 2 intravenously on day 1 of each 5 weeks of radiation treatment). The primary endpoint was overall survival, analysed by intention-to-treat. The CRITICS trial is registered at ClinicalTrials.gov, number NCT00407186; EudraCT, number 2006-004130-32; and CKTO, 2006-02. Between Jan 11, 2007, and April 17, 2015, 788 patients were enrolled and randomly assigned to chemotherapy (n=393) or chemoradiotherapy (n=395). After preoperative chemotherapy, 372 (95%) of 393 patients in the chemotherapy group and 369 (93%) of 395 patients in the chemoradiotherapy group proceeded to surgery, with a potentially curative resection done in 310 (79%) of 393 patients in the chemotherapy group and 326 (83%) of 395 in the chemoradiotherapy group. Postoperatively, 233 (59%) of 393 patients started chemotherapy and 245 (62%) of 395 started chemoradiotherapy. At a median follow-up of 61·4 months (IQR 43·3-82·8), median overall survival was 43 months (95% CI 31-57) in the chemotherapy group and 37 months (30-48) in the chemoradiotherapy group (hazard ratio from stratified analysis 1·01 (95% CI 0·84-1·22; p=0·90). After preoperative chemotherapy, in the total safety population of 781 patients (assessed together), there were 368 (47%) grade 3 adverse events; 130 (17%) grade 4 adverse events, and 13 (2%) deaths. Causes of death during preoperative treatment were diarrhoea (n=2), dihydropyrimidine deficiency (n=1), sudden death (n=1), cardiovascular events (n=8), and functional bowel obstruction (n=1). During postoperative treatment, grade 3 and 4 adverse events occurred in 113 (48%) and 22 (9%) of 233 patients in the chemotherapy group, respectively, and in 101 (41%) and ten (4%) of 245 patients in the chemoradiotherapy group, respectively.

    To analyze prognostic factors associated with long-term outcomes in patients with resected pancreatic cancer treated with chemotherapy (CT) and surgery with or without external beam radiotherapy (EBRT). From January 1995 to December 2012, 95 patients with adenocarcinoma of the pancreas and locoregional disease [clinical stage IB-IIA (n = 45; 47 %), IIB-IIIC (n = 50; 53 %)] were treated with curative resection [R0 (n = 52; 55 %), R1 (n = 43, 45 %)] and CT with (n = 60; 63 %) or without (n = 35; 37 %) EBRT (45-50.4 Gy). Additionally, 29 patients (48 %) also received a pre-anastomosis IOERT boost (applicator diameter size, 7-10 cm; dose, 10-15 Gy; beam energy, 9-18 MeV). With a median follow-up of 17.2 months (range, 1-182), 2-year overall survival (OS), disease-free survival (DFS), and locoregional control were 28, 20, and 53 %, respectively. Univariate analyses showed that IIB-IIIC stage (HR, 2.23; p = 0.04), R1 margin resection status (HR, 2.09; p = 0.04), no vascular resection (HR, 0.42; p = 0.02), and not receiving external beam radiotherapy (HR, 2.70; p = 0.004) were associated with locoregional recurrence. In the multivariate analysis, only R1 margin resection status (HR, 2.63; p = 0.009) and not receiving EBRT (HR, 2.91; p = 0.002) retained significance with regard to locoregional recurrence. We observed no difference in toxicity between patients treated with or without EBRT (p = 0.44). Overall treatment mortality was 3 %. No long-term treatment-related death occurred. Although adjuvant CT is still the standard of care for resected pancreatic tumors, OS remains modest owing to the high risk of distant metastases. Locoregional treatment needs to be tested in the context of more efficient systemic therapy. (orig.)

    To investigate the value of intensity modulated radiation therapy (IMRT) for patient with gynecological malignancies after treatment of hysterectomy and chemotherapy/radiotherapy. All 32 patients with cervical or endometrial cancer after hysterectomy received full course IMRT after 1 to 3 cycles of chemotherapy (Karnofsky performance status(KPS) > or =70). Seventeen of these patients underwent postoperative preventive irradiation and the other 15 patients were pelvic wall recurrence and/or retroperitoneal lymph node metastasis, though postoperative radiotherapy and/or chemotherapy had been given after operation. The median dose delivered to the PTV was 56.8 Gy for preventive irradiation, and 60.6 Gy for pelvic wall recurrence or retroperioneal lymph node metastasis irradiation. It was required that 90% of iso-dose curve could covere more than 99% of GTV. However, The mean dose irradiated to small intestine, bladder, rectum, kidney and spinal cord was 21.3 Gy, 37.8 Gy, 35.3 Gy, 8.5 Gy, 22.1 Gy, respectively. Fourteen patients presented grade I (11 patients) or II (3 patients) digestive tract side-effects, Five patients developed grade I or II bone marrow depression. Twelve patients had grade I skin reaction. The overall 1-year survival rate was 100%. The 2- and 3- year survival rate for preventive irradiation were both 100%, but which was 5/7 and 3/6 for the patients with pelvic wall recurrence or retroperioneal lymph node metastasis. Intensity modulated radiation therapy can provide a better dose distribution than traditional radiotherapy for both prevention and pelvic wall recurrence or retroperioneal lymph node metastasis. The toxicity is tolerable. The adjacent organs at risk can well be protected.

    Nedaplatin (CDGP), which is a CDDP derivative, has been reported to be an effective anticancer agent for head and neck cancer. This study was performed to assess the feasibility of chemotherapy by superselective intraarterial infusion of nedaplatin (CDGP) in patients with oral cancers. Ten patients were treated with chemotherapy by superselective intraarterial infusion of CDGP combined with radiotherapy. The complete and partial response rates were 7/10 (70%) and 3/10 (30%), respectively. Nine patients showed grade 1-2 hematological toxicity including leukocytopenia and anemia. Thrombocytopenia of grade 4 was seen in only one patient. However, all the patients were free from renal dysfunction. From these results, it is suggested that this combination therapy might be quite effective and safe. Further study will be needed to determine its efficacy against oral cancer. (author)

    HemoHIM significantly reduced the damage of liver and kidney by cisplatin. In a preliminary clinical study, 85 patients, diagnosed with breast or uterine cervix cancer, were administered with HemoHIM (6 g/day) for 12 weeks during radiation and/or chemotherapy. Age-matched 209 patients were monitored as control group. In the HemoHIM group, fewer cases of severe leucopenia (<3,000 leukocytes/mm 3 ) were shown compared with the control group, and it was more evident in the breast cancer patients. In conclusion, HemoHIM may be a beneficial supplement during radiotherapy and chemotherapy for enhancing the anti-tumor efficacy and reducing the side effects

    There are sound radiobiologic and suggestive clinical rationale for superfractionating the radiotherapeutic regimens employed for the therapy of rapidly growing malignancies. Oat cell carcinoma of the bronchus is such a tumor. The authors report their experience combining aggressive systemic combination chemotherapy with supperfractionated radiotherapy for the treatment of limited oat cell carcinoma of the bronchus. Overall, patient tolerance was satisfactory and a complete remission rate of 74% was achieved. It remains to be proven, in a prospective randomized fashion, whether this approach is superior to current conventional management

    Full Text Available Background. To report on the use and feasibility of a multimodality approach using concomitant radiotherapy and chemotherapy in patients with high-risk nonmelanoma skin carcinoma (NMSC of the head and neck. Methods. Records of patients with NMSC of the head and neck who received concomitant CRT at the University of North Carolina between 2001 and 2007 were reviewed. Results. Fifteen identified patients had at least one of the following high-risk factors: T4 disease (93%, unresectability (60%, regional nodal involvement (40%, and/or recurrence (47%. Ten patients were treated in the definitive setting and five in the postoperative setting. Platinum based chemotherapy was given in 14 (93% patients. Ten of fifteen (67% patients completed all planned chemotherapy treatments, and thirteen patients (87% completed at least 80% of planned chemotherapy. Mild radiation dermatitis occurred in all patients and reached grade 3 in 13% of patients. No patients experienced grade 4 or 5 toxicity. With a median followup of 31 months in surviving patients, the 2-year actuarial locoregional control and relapse-free survival were 79% and 49%, respectively. Conclusions. Definitive or postoperative chemoradiotherapy for patients with locally advanced or regionally metastasized NMSC of the head and neck appears feasible with acceptable toxicities and favorable locoregional control.

    Forty-seven patients with operable squamous cell carcinoma of the thoracic esophagus were treated by initial concurrent chemoradiotherapy (CDDP-5 FU-44 Gy) followed by definitive high-dose of radiotherapy (CRT group: 35 patients) or surgery (CRT-S group: 12 patients). Clinical CR rate showed 86% in CRT group; and pathological CR rate 18% in CRT-S group. The overall median survival was 45 months, survival at 1, 3, 5 years being 96%, 52%, 48%, respectively. No treatment-related mortality was observed. The rate of the 'esophagus conservation' was 66%. Our results demonstrated that the multidisciplinary approach with intent to conserve the esophagus centering on high-dose radiotherapy and concurrent chemotherapy provides a significant improvement of both survival and quality of life in patients with operable esophageal carcinoma.

    Since the majority of patients with osteosarcomas of the limbs develop lung metastases, radiotherapy and/or chemotherapy are used as adjuvant therapy immediately after treatment of the primary. This article questions the roles of radiotherapy and chemotherapy in this instance. A brief review of previous non-randomized studies is made. The overall conclusion seemed to be that although adjuvant chemotherapy resulted in a higher survival of patients with osteosarcoma, in comparison with historical controls, this form of treatment has not proven to be superior to the benefit achieved by lung irradiation. In the light of these studies, the Clinical Cooperative Group Radiotherapy/Chemotherapy (E.O.R.T.C.) and the International Society for Pediatric Oncology (S.I.O.P.) have initiated a prospective, randomized trial comparing chemotherapy, radiotherapy of the lungs and a combination of both treatments. The details of these treatments are given. This trial will try to answer very fundamental questions on adjuvant therapy in osteosarcomas. Active participation of as many medical centres as possible is requested.

    2008-01-01

    Purpose: To retrospectively compare the outcome of upfront chemotherapy plus radiotherapy (CRT) and the outcome of the use of extended radiotherapy (RT) only for intracranial germinoma. Methods and Materials: Of 81 patients with tissue-confirmed intracranial germinoma, 42 underwent CRT and 39 underwent RT only. For CRT, one to five cycles of upfront chemotherapy was followed by involved-field or extended-field RT, for which the dose was dependent on the M stage. For RT only, all 39 patients underwent craniospinal RT alone. The median follow-up was 68 months. Results: The 5- and 10-year overall survival rate was 100% and 92.5% for RT alone and 92.9% and 92.9% for CRT, respectively. The 5-year recurrence-free survival rate was 100.0% for RT and 88.1% for CRT (p = 0.0279). No recurrences developed in patients given RT, but four relapses developed in patients who had received CRT-three in the brain and one in the spine. Only one patient achieved complete remission from salvage treatment. The proportion of patients requiring hormonal replacement was greater for patients who received RT than for those who had received CRT (p = 0.0106). Conclusions: The results of our study have shown that the better quality of life provided by CRT was compensated for by the greater rate of relapse. The possible benefit of including the ventricles in involved-field RT after upfront chemotherapy, specifically for patients with initial negative seeding, should be addressed in a prospective study

    Purpose: A recent randomized clinical trial has demonstrated that direct decompressive surgery plus radiotherapy was superior to radiotherapy alone for the treatment of metastatic epidural spinal cord compression. The current study compared the cost-effectiveness of the two approaches. Methods and Materials: In the original clinical trial, clinical effectiveness was measured by ambulation and survival time until death. In this study, an incremental cost-effectiveness analysis was performed from a societal perspective. Costs related to treatment and posttreatment care were estimated and extended to the lifetime of the cohort. Weibull regression was applied to extrapolate outcomes in the presence of censored clinical effectiveness data. Results: From a societal perspective, the baseline incremental cost-effectiveness ratio (ICER) was found to be $60 per additional day of ambulation (all costs in 2003 Canadian dollars). Using probabilistic sensitivity analysis, 50% of all generated ICERs were lower than $57, and 95% were lower than $242 per additional day of ambulation. This analysis had a 95% CI of -$72.74 to 309.44, meaning that this intervention ranged from a financial savings of $72.74 to a cost of $309.44 per additional day of ambulation. Using survival as the measure of effectiveness resulted in an ICER of $30,940 per life-year gained. Conclusions: We found strong evidence that treatment of metastatic epidural spinal cord compression with surgery in addition to radiotherapy is cost-effective both in terms of cost per additional day of ambulation, and cost per life-year gained

    The optimal delay in the start of chemotherapy following rectal cancer surgery has not yet been identified. However, postponed adjuvant therapy has been proven to be connected with a significant survival detriment. We aimed to investigate whether the time to initiation of adjuvant treatment can be influenced by the application of minimally invasive surgery rather than traditional open surgery. By comprehensively evaluating the available inherent literature, several factors appear to be associated with delayed postoperative chemotherapy. Some of them are strictly related to surgical short-term outcomes. Laparoscopy results in shortened length of hospital stay, reduced surgical morbidity and lower rate of wound infection compared to conventional surgery. Probably due to such advantages, the application of minimally-invasive surgery to treat rectal malignancies seems to impact favorably the possibility to start adjuvant chemotherapy within an adequate timeframe following surgical resection, with potential improvement in patient survival.

    We sought to review outcomes in patients with stage IVB carcinoma of the cervix treated with irradiation in combination with chemotherapy. We report outcomes of 24 consecutive patients with good performance status treated from 1998 to 2005. Most of these patients underwent concurrent irradiation with platinum-based chemotherapy. Some patients received subsequent systemic chemotherapy. All patients underwent external beam radiotherapy; 7 patients (29%) had additional high-dose-rate and 12 (50%) low-dose-rate brachytherapy. Two patients (8%) received an intensity modulated radiation therapy (IMRT) boost instead of brachytherapy. The mean dose to point A was variable (73.9±19.2 Gy). Twenty patients (83%) received radio-sensitizing platinum-based chemotherapy, and the remaining had radiotherapy alone. Seven patients (29%) had further combination chemotherapy. Therapy was well tolerated. The overall survival was 44% at 36 months and 22% at 5 years. Patients with stage IVB cervical cancer have mostly been treated with palliative intent. With the advent of concurrent chemoradiation, we have treated many of these cases with aggressive combination therapy. In this series, the use of radiotherapy and multiagent chemotherapy in patients with stage IVB cervical carcinoma and good performance status was well tolerated and resulted in higher survival rates than previously reported.

    Purpose: This study investigated the short- and medium-term effects of pelvic radiotherapy and surgery on the sexual function of women treated for cervical cancer. Methods and Materials: Sixteen women with Stages I, II, or III disease referred for radiotherapy treatment were assessed. Six had undergone prior hysterectomy. The women were assessed with questionnaires prior to radiotherapy, at completion of radiotherapy, and at 6 weeks and 14 weeks after radiotherapy treatment. The clinical findings at routine follow-up were noted. Results: The study showed significant changes in sexual activity and satisfaction as a result of treatment. This was due to a number of physical and psychological factors. The level of sexual activity was lowest at completion of radiotherapy treatment. A feeling of vaginal shortening was the most frequent reason and was more common in women who were treated with surgery and radiotherapy. Dyspareunia, bleeding, and concern of bleeding and/or recurrence were all significant factors. Conclusions: The questionnaires were an effective way of assessing women's sexual function. Radiotherapy caused sexual dysfunction in one-half of women. Combined treatment with radiotherapy and surgery results in a higher risk than radiotherapy alone. Women with cervical cancer and undergoing radiotherapy treatment require considerable counseling and support

    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.

Patients with stage II NHL were subdivided into stage II1 (limited type) and stage II2 (advanced type) from the state of neck nodes. Stage II1 was defined as involvement of unilateral cervical nodes less than 4 cm in diameter as well as Waldeyer's ring involvement. Other stage II cases were classified as stage II2. All 17 patients with stage I HNL were treated with radiation therapy alone. Their diseases were well controlled, and none of them died of causes related to the lymphoma. Among 14 patients with stage II1 NHL, the 5-year survival rate for the 9 patients treated with radiation therapy alone was 87.5%. Until 1982, 19 of 21 patients with stage II2 NHL treated with radiation therapy alone or radiation therapy and adjuvant chemotherapy (VEMP or COPP) died within 5 years mainly of disseminated diseases. Since 1983, CHOP had been used as the main treatment as well as radiotherapy for the 12 stage II2 NHL patients. So far, only 3 of them relapsed and 2 of them died of causes related to the lymphoma. Only 1 of these 12 patients was T-cell lymphoma compared to 7 of 9 stage II2 patients before 1982. This suggests that patients with stage I and those with limited stage II can be safely treated with radiotherapy. Also aggressive chemotherapy as well as radiotherapy should be used for patients with advanced stage II HNL involving Waldeyer's ring. (author)

    Purpose: Fractionated radiotherapy and chemotherapy for locally advanced pancreatic cancer achieves only modest local control. This prospective trial evaluated the efficacy of a single fraction of 25 Gy stereotactic body radiotherapy (SBRT) delivered between Cycle 1 and 2 of gemcitabine chemotherapy. Methods and Materials: A total of 16 patients with locally advanced, nonmetastatic, pancreatic adenocarcinoma received gemcitabine with SBRT delivered 2 weeks after completion of the first cycle. Gemcitabine was resumed 2 weeks after SBRT and was continued until progression or dose-limiting toxicity. The gross tumor volume, with a 2-3-mm margin, was treated in a single 25-Gy fraction by Cyberknife. Patients were evaluated at 4-6 weeks, 10-12 weeks, and every 3 months after SBRT. Results: All 16 patients completed SBRT. A median of four cycles (range one to nine) of chemotherapy was delivered. Three patients (19%) developed local disease progression at 14, 16, and 21 months after SBRT. The median survival was 11.4 months, with 50% of patients alive at 1 year. Patients with normal carbohydrate antigen (CA)19-9 levels either at diagnosis or after Cyberknife SBRT had longer survival (p <0.01). Acute gastrointestinal toxicity was mild, with 2 cases of Grade 2 (13%) and 1 of Grade 3 (6%) toxicity. Late gastrointestinal toxicity was more common, with five ulcers (Grade 2), one duodenal stenosis (Grade 3), and one duodenal perforation (Grade 4). A trend toward increased duodenal volumes radiated was observed in those experiencing late effects (p = 0.13). Conclusion: SBRT with gemcitabine resulted in comparable survival to conventional chemoradiotherapy and good local control. However, the rate of duodenal ulcer development was significant

    Forty-six patients with gliomas were introduced after surgery into a therapeutic programme of six cycles of combination chemotherapy with VM 26 and CCNU, followed by delayed irradiation six months after surgery with an average dose of 5,800 rads. After irradiation the same preradiation chemotherapy was readministered for an average of four cycles. The results were compared to those from another group of 28 patients treated only by the same chemotherapy (CRC and C groups successively). Twelve patients (26%) died before irradiation in the CRC groups, six patients (13%) had recurrences at the time of irradiation, and 28 patients (61%) had no clinical or radiological signs of recurrence at the time of irradiation. For the total of treated patients the median survival after surgery was 17 months, and 46% of the patients were surviving at 18 months. The percentage of survivors at 18 months was significantly more elevated in the group treated by combination chemotherapy and delayed irradiation than in a control group treated by the same combination chemotherapy alone. This result suggests that in approximately 50% of cases combination chemotherapy after surgery, and delayed irradiation six months after surgery, cumulated their effects on survival time. (author)

    Apart from damage to bladder innervation, a number of local diseases and treatments such as radiotherapy can induce lower urinary tract functional disorders. Some of these disorders can be treated according to the principles used in the management of neurogenic bladder. The purpose of this review is to report the functional consequences of pelvic endometriosis, radiotherapy, colorectal surgery and urinary incontinence surgery with particular emphasis on situations in which a neurogenic mechanism is suspected.

    Purpose : To evaluate the role of combination therapy of external radiotherapy and chemotherapy in the management of advanced esophageal cancer as a primary treatment compared with radiation therapy alone. Methods and Materials : A retrospective review of evaluable 55 esophageal cancer patients referred to the Department of Therapeutic Radiology, Paik Hospital for the external radiotherapy between Jul. 1983 and Dec.1994 was undertaken. Combined therapy patients (A group) were 30 and radiation alone patients (B group) were 25. Median age was 60 years old in A group(ranges : 42-81) and 65 years old in B group (ranges : 50-81). The male patients were 53. The fifty patients had squamous cell carcinomas. Radiation doses of 2520-6480c Gy were delivered over a period of 4-7 weeks. using 4MV LIVAC. Chemotherapy was administered in bolus injection before, after, or during the course of external radiotherapy. The local control rate and patterns of failure according to both treatment modalities and 1,2 year survival rates according to prognostic factors (stage, tumor length, radiation dose etc.) were analysed. Results : Median follow up period was 7 months (range : 2-73 months). Median survival was 7.5 months (20 days-29 months) in A group and 5 months(20 days-73 months) in B group. The 1,2 YSRs were 26.7%, 8.9% in A group. 12.7%, 4.3% in B group (p>0.05), respectively. The 1,2 YSRs according to stage(II/III), tumor length (5cm more or less). radiation dose(5000c Gy more or less) of A and B group were analyzed and the differences of survival rates of both treatments were not statistically significant. But among group B, patients who received 5000c Gy or more showed significant survival benefits (p<0.05). The treatment response rates of A and B group were 43.8%, 25.0%, respectively. Complete response rate of 25.0% in A and 8.3% in B were achieved. The local failure and distant metastasis were 52.4%, 23.8% in A group. 64.3%, 14.3% in B group, respectively. The combination

    Objective: To evaluate the effectiveness and the cosmetics result of radiotherapy after conservative surgery for early breast cancer. Methods: Altogether 109 patients were treated by post-operative whole-breast irradiation and a tumor bed boost from May, 1995 to December, 2002. Among them 79 cases received a brachytherapy boost ( 192 Ir HDR implant Nucletron ) of 10-12 Gy(DB) by single plan of implantation with 1.5 cm between the needles for T1 and double plan for T2-4 tumors, and 30 cases received an electron beam boost with 15 Gy. External beam irradiation was applied to the whole breast with 45-52 Gy(mean 48.6 Gy) in 25 fractions over 5 weeks followed or concurrently with chemotherapy (CMF or CEF) and hormonotherapy. The cosmetic result was scored by a doctor and patients via questionnaire. Results: The median follow-up time was 52 months. The actuarial 5-year overall survival rate was 93.8% using Kaplan-Meier method and the within breast recurrence rate was 6.5%. No radiation- induced ulcer in the breast occurred except acute inflammation of skin around the pinholes in 5 patients. Cosmetic results were scored to be good by patients and the doctor (81% and 87%, respectively) for 75 followed-up cases, and good cosmetic rate was reported by the doctor for 82% (39/48) of the cases treated with brachytherapy boost and 85.2%(23/27) for those treated with external beam boost. There was no difference in cosmetic results between these two groups(P>0.05). Conclusion: In patients at high risk for local recurrence, tumor-bed boost with brachytherapy or electron beam carried out after limited surgery and external radiotherapy can provide satisfactory local control without morbidity. Cosmetic result may not be influenced by the boost technique. (authors)

    Breast conservative surgery after neoadjuvant chemotherapy intends to remove any residual tumor with negative margins. The purpose of this study was to analyze the preoperative clinical-pathological factors influencing the margin status after conservative surgery in breast cancer patients receiving neoadjuvant chemotherapy. A retrospective study of 91 breast cancer patients undergoing neoadjuvant chemotherapy (92 breast lesions) during the period 2006 to 2013. A Cox regression analysis to identify baseline tumor characteristics associated with positive margins after breast conservative surgery was performed. Of all cases, 71 tumors were initially treated with conservative surgery after neoadjuvant chemotherapy. Pathologic exam revealed positive margins in 16 of the 71 cases (22.5%). The incidence of positive margins was significantly higher in cancers with initial size >5cm (P=.021), in cancers with low tumor grade (P=.031), and in patients with hormone receptor-positive cancer (P=.006). After a median follow-up of 45.2 months, 7 patients of the 71 treated with conservative surgery had disease recurrence (9.8%). There was no significant difference in terms of disease-free survival according to the margin status (P=.596). A baseline tumor size >5cm, low tumor grade and hormone receptor-positive status increase the risk for surgical margin involvement in breast conservative surgery after neoadjuvant chemotherapy.

    This retrospective study analyzes the safety and feasibility of concurrent chemoradiotherapy (CRT) in adjuvant treatment of soft tissue sarcoma (STS). A total of 158 patients with STS were retrospectively analyzed. Anthracycline-based computed tomography was performed in high-risk patients. Acute radiotherapy toxicity and chemotherapy-related toxicity were assessed according to the Common Terminology Criteria for Adverse Events 4.0; late radiotherapy toxicity was recorded according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. Fifty-four (34.2%) patients received CRT. Mean follow up was 5.4 years (range .2-21.1 years). Local DFS-recurrence-free survival, distant DFS-relapse-free survival, and overall survival were 79.1%, 76.4%, and 64.6%, respectively, at last follow-up. Leukopenia occurred in 11.4% of patients. Skin acute toxicity developed in 60.1% of patients and determined interruption of radiotherapy treatment in 19 (12%) patients. Nineteen patients (12%) experienced moderate fibrosis (grade 2). Mild and moderate joint stiffness was recorded in 16 (10.1%) patients. Size ≥5 cm was the only predictor of local recurrence at multivariate analysis (hazard ratio [HR] 9.65, 95% confidence interval [CI] 1.28-72.83, p = .028). Age and stage resulted as independent distant relapse predictors (HR 4.77, 95% CI 1.81-12.58, p = .002 and HR 4.83, CI 1.41-16.57, p = .012, respectively). At Cox regression univariate analysis, Karnofsky Performance Status, size, and stage were significant survival predictors (HR 2.23, 95% CI 1.02-4.87, p = .045; HR 2.88, 95% CI 1.10-7.52, p = .031; HR 2.59, 95% CI 1.11-6.04, p = .028). Concurrent CRT is a well-tolerated treatment option with no additional toxicity compared to exclusive radiotherapy or sequential CRT.

    This report concerns the design and results of a randomized prospective trial (SECOG I) in the treatment of advanced Stage III and IV head and neck cancer with radical radiotherapy combined with polychemotherapy. Synchronous administration of chemotherapy and radiotherapy was compared with sequential chemotherapy and radiotherapy and VBM (vincristine, bleomycin and methotrexate) compared with VBM plus 5-fluorouracil in a 2 x 2 standard factorial design. Two-hundred-and-seventy patients were entered and 267 were included in the analysis. Treatment did not present serious problems of toxicity. The addition of 5-fluorouracil to VBM produced a significant improvement in disease-free survival (P=0.04) though not in overall survival. Synchronous chemotherapy was similarly better than sequential chemotherapy, though not significantly so (P=0.1). A new study (SECOG II), based on this was started in February 1984, and one-third of the patients are now being allocated to treatment by radiotherapy as the sole method of treatment. (author)

    Evaluated in this study were the feasibility and the efficacy of concurrent low dose fractionated radiotherapy (LD-FRT) and chemotherapy as palliative treatment for recurrent/progressive glioblastoma multiforme (GBM). Eligible patients had recurrent or progressive GBM, Karnofsky performance status ≥70, prior surgery, and standard radiochemotherapy treatment. Recurrence/progression disease during temozolomide (TMZ) received cisplatin (CDDP; 30 mg/m{sup 2} on days 1, 8, 15), fotemustine (FTM; 40 mg/m{sup 2} on days 2, 9, 16), and concurrent LD-FRT (0.3 Gy twice daily); recurrence/progression after 4 months from the end of adjuvant TMZ were treated by TMZ (150/200 mg/m{sup 2} on days 1-5) concomitant with LD-FRT (0.4 Gy twice daily). Primary endpoints were safety and toxicity. A total of 32 patients were enrolled. Hematologic toxicity G1-2 was observed in 18.7% of patients and G3-4 in 9.4%. One patient (3.1%) had complete response, 3 (9.4%) had partial response, 8 (25%) had stable disease for at least 8 weeks, while 20 patients (62.5%) experienced progressive disease. The clinical benefit was 37.5%. Median progression-free survival (PFS) and overall survival (OS) were 5 and 8 months, respectively. Survival rate at 12 months was of 27.8%. LD-FRT and chemotherapy for recurrent/progressive GBM have a good toxicity profile and clinical outcomes, even though further investigation of this novel palliative treatment approach is warranted.

    Purpose/Objective: To determine the role of radiation therapy and chemotherapy in the treatment of Merkel Cell Carcinoma (MCC), a highly aggressive skin tumor. Materials and Methods: A retrospective analysis of 27 patients treated at the Rabin Medical Center in Israel is presented. Data on 40 patients, including 13 additional patients from the Israel Cancer Registry, were analyzed for prognostic factors using uni- and multivariate analysis. Results: Univariate analysis revealed regional lymph node involvement and coexistence of secondary primary as unfavorable prognostic factors. In multivariate analysis only lymph node involvement showed borderline statistical significance. Radiation therapy was highly effective when given as consolidation after surgery or chemotherapy. In 11 patients irradiated prophylactically only one in-field relapse (9%) occurred. Radiation therapy yielded responses in 15 of 15 measurable sites (5CR, 10 PR). Chemotherapy produced responses in 18 of 26 treatments (70%), mostly CR (41%). However, in the absence of radiation therapy the responses were of short duration. Conclusion: Our data support combined treatment with chemotherapy followed by irradiation for advanced loco-regional disease. Further large scale investigations are warranted to confirm this approach

    An 89-year-old woman underwent breast-conserving surgery and axillary lymph node dissection (right AC region, T2N0M0, stage 2A, invasive ductal carcinoma, papillotubular type) for right breast cancer in February 2005. She received postoperative radiotherapy to the residual breast. She then developed marked edema of the right arm and right breast. A mass developed in the right breast in March 2011 and March 2013. This was originally suspected to be an ipsilateral breast recurrence of the cancer, but turned to be angiosarcoma after developing recurrent mass in March 2013, which histopathology was proved to be showed angiosarcoma of the breast. The patient subsequently had repeated intradermal and subcutaneous metastases and recurrence. She is currently receiving chemotherapy with docetaxel (30 mg/m 2 biweekly). This interesting case of angiosarcoma of the breast after breast-conserving surgery for breast cancer is reported. (author)

    One hundred and sixteen cases of brain metastases of lung cancer were retrospectively analysed with special reference to the relative significance of surgery and radiotherapy. The median survival time from diagnosis of brain metastases was 1.2 months in 27 cases without treatment, 2.5 months in 51 cases treated by surgery alone, 4.2 months in 31 cases treated by radiotherapy alone and 6.5 months in 7 cases treated by surgery and radiotherapy. The survival rate in patients treated by radiotherapy was significantly better than in those not treated by radiotherapy. However, the effect of surgery was not significant in prolongation of survival time. On the other hand, the rate of improvement in neurological symptoms assessed at one month after the initiation of treatment was 80.9% in 47 cases treated by surgery and 19.4 % in 31 cases treated by radiotherapy. The result suggested that surgery is superior to radiotherapy in alleviating neurological symptoms. It is important to understand the nature of effect of each treatment. A better result will be anticipated by proper selection or combination of these treatments. (author)

    Purpose To investigate the impact of modern postoperative radiotherapy (PORT) on overall survival (OS) for patients with N2 non–small-cell lung cancer (NSCLC) treated nationally with surgery and adjuvant chemotherapy. Patients and Methods Patients with pathologic N2 NSCLC who underwent complete resection and adjuvant chemotherapy from 2006 to 2010 were identified from the National Cancer Data Base and stratified by use of PORT (≥ 45 Gy). A total of 4,483 patients were identified (PORT, n = 1,850; no PORT, n = 2,633). The impact of patient and treatment variables on OS was explored using Cox regression. Results Median follow-up time was 22 months. On univariable analysis, improved OS correlated with younger age, treatment at an academic facility, female sex, urban population, higher income, lower Charlson comorbidity score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT. On multivariable analysis, improved OS remained independently predicted by younger age, female sex, urban population, lower Charlson score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT (hazard ratio, 0.886; 95% CI, 0.798 to 0.988). Use of PORT was associated with an increase in median and 5-year OS compared with no PORT (median OS, 45.2 v 40.7 months, respectively; 5-year OS, 39.3% [95% CI, 35.4% to 43.5%] v 34.8% [95% CI, 31.6% to 38.3%], respectively; P = .014). Conclusion For patients with N2 NSCLC after complete resection and adjuvant chemotherapy, modern PORT seems to confer an additional OS advantage beyond that achieved with adjuvant chemotherapy alone.

    This Phase II study was conducted to evaluate the activity and feasibility of a regimen of nedaplatin and 5-fluorouracil as induction chemotherapy, followed by intensity-modulated radiotherapy concurrent with chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma. Patients received neoadjuvant chemotherapy comprised two cycles of 5-fluorouracil at 700 mg/m 2 /day administered on days 1-4 as continuous intravenous infusion and nedaplatin (100 mg/m 2 administered intravenous (i.v.) over 2 h) given after the administration of 5-fluorouracil on day 1, repeated every 3 weeks, followed by intensity-modulated radiotherapy concurrent with nedaplatin. During intensity-modulated radiotherapy, nedaplatin was administered at a dose of 100 mg/m 2 intravenous infusion on days 1, 22 and 43, given -60 min before radiation. Fifty-nine (95.8%) of the 60 patients were assessable for response. Thirty-eight cases of complete response and 14 cases of partial response were confirmed after completion of chemoradiation, with the objective response rate of 86.7% (95% confidence interval (CI), 78.1-95.3%). The median follow-up period was 48 months (range, 30-62 months). The 3-year progression-free survival and overall survival were 75.0% (95% CI, 63.0-87.0%) and 85.5% (95% CI, 75.9-95.1%). No patient showed Grade 3 or higher renal dysfunction. The most commonly observed late effect was xerostomia, but the severity diminished over time, and the detectable xerostomia at 24 months was 10.2%. There were no treatment-related deaths during this study. Neoadjuvant chemotherapy with nedaplatin and 5-fluorouracil followed by concomitant nedaplatin and intensity-modulated radiotherapy is an effective and safe treatment for Southern China patients affected by locoregionally advanced nasopharyngeal carcinoma.

    High indexes of loco-regional recurrence in patients with rectal cancer have stimulated the search of complementary therapy. Since the sixties, neo adjuvant radiotherapy has gained space in order to reduce local recurrence and to increase the survival of these patients. Recently some publications have pointed out the importance of associating chemotherapy and total excision of mesorectum to the radiotherapy in the same way. The results of large prospective researches are expected to determine the exact role of this association. (author)

    Background: Nitroglycerin, a nitric oxide donor agent, reduces the expression of hypoxia-inducible factor-1α (HIF-1α) and could be a normalizer of the tumor microenvironment. Both factors are associated with chemo-radio-resistance. The aim of this study was to determine the safety profile and efficacy of nitroglycerin administration with chemo-radiotherapy in patients with locally advanced non-small cell lung cancer (NSCLC). Methods: This is a phase II trial of locally advanced NSCLC patients treated with cisplatin and vinorelbine plus concurrent nitroglycerin with radiotherapy. A 25-mg NTG patch was administered to the patients for 5 days (1 day before and 4 days after chemotherapy induction and consolidation) and all day during chemo-radiotherapy. VEGF plasmatic level was determined before and after two cycles of chemotherapy. Results: Thirty-five patients were enrolled in this trial. Sixty-three percent of patients achieved an overall response after induction of chemotherapy, and 75% achieved an overall response after chemo-radiotherapy. The median progression-free survival was 13.5 months (95% CI, 8.8–18.2), and the median overall survival was 26.9 months (95% CI, 15.3–38.5). Reduction of VEGF level was associated with better OS. The toxicity profile related to nitroglycerin included headache (20%) and hypotension (2.9%). Conclusions: The addition of nitroglycerin to induction chemotherapy and concurrent chemoradiotherapy in patients with locally advanced NSCLC has an acceptable toxicity profile and supports the possibility to add nitroglycerin to chemotherapy and radiotherapy. A randomized trial is warranted to confirm these findings

    A prospective study has been performed to assess the feasibility and toxicity of administering neoadjuvant chemotherapy with methotrexate and cisplatin prior to radical radiotherapy. Twenty patients with advanced transitional cell carcinoma of the bladder were assessed after each of 3 courses of chemotherapy, after radiotherapy and 6 months following treatment. Of particular concern was whether neoadjuvant chemotherapy compromised the ability to give potentially curative radical radiotherapy, delayed effective palliation of distressing urinary symptoms, or allowed local tumour progression prior to definitive treatment. It was concluded that this chemotherapy regimen was well tolerated, did not compromise the ability to give radical radiotherapy and resulted in the prompt palliation of urinary symptoms. This treatment, however, did not stop the development or progression of metastatic disease in some patients. In only 1 patient was there local progression during chemotherapy. (author)

    We analyzed the results of radiotherapy in 36 patients with hypopharyngeal carcinoma. The overall 2-year and 5-year survival rates were 45.3% and 31.1%, respectively. For 23 patients given radical irradiation, the corresponding figures were 37.8% and 28.3%. However, in 16 patients receiving a combined therapy of radical irradiation and chemotherapy, mainly an intraarterial injection of cisplatin, the survivals were better; the 2-year survival rate was 50.0% and four patients have survived for more than three years without recurrence. In managing patients with hypopharyngeal carcinoma, this combined therapy would improve therapeutic outcome and also assist in larynx preservation. (J.P.N.)

    Objective The goal of this study is to determine the effect of primary surgery vs radiotherapy (RT) on overall survival (OS) in patients with early stage oral cavity squamous cell carcinoma (OCSCC). In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

    Twenty-two patients with limited unresectable squamous cell lung cancer were treated with 6 courses of combination chemotherapy consisting of cyclophosphamide, adriamycin, cisplatin, and bleomycin (CAP-Bleo) and short-course thoracic irradiation started after the first 4 weeks of chemotherapy. Of 20 patients with visible tumor who were treated with 4 weeks of chemotherapy alone, 10 (50%) had a tumor regression in that 4 week period and 10 did not. Those patients with tumor regression had significantly better progression free and overall survivals than did patients with no chemotherapy regressions (medians of 258 days vs. 136 days and 356 days vs. 150 days respectively). The original bleomycin dose had to be reduced by 50% primarily because of excessive radiation esophagitis that has not been reported with use of either the CAP regimen or bleomycin along in conjunction with thoracic irradiation. An initial chemotherapy regression seems to be a good prognosticator for progression-free and overall survival in patients with limited squamous cell lung cancer treated with combined chemotherapy and radiotherapy

    Purpose: To evaluate a simultaneous integrated boost (SIB) strategy in preoperative radiotherapy of rectal cancer patients following neoadjuvant chemotherapy using pre- and post-chemotherapy tumor volumes assessed by MRI. Materials and methods: Ten patients with locally advanced rectal cancer, receiving chemotherapy prior to radiotherapy, were included in this study. Pre- and post-chemotherapy MR tumor images were co-registered with CT images for IMRT planning. Three planning target volumes were defined: PTV risk , PTV pre c hemo and PTV post c hemo . For SIB, prescribed mean doses to the PTVs were 46, 50 and 58 Gy, respectively, given in 25 fractions. Organs at risk (OARs) were bladder and intestine. The novel three-volume SIB strategy was compared to a conventional two-volume SIB plan, in which PTV post c hemo was ignored, using dose-volume histograms (DVHs) and the generalized equivalent uniform dose (gEUD). Results: All patients showed tumor shrinkage following chemotherapy. For the novel SIB, population-based mean doses given to PTV risk , PTV pre c hemo and PTV post c hemo were 46.8 ± 0.3, 50.6 ± 0.4 and 58.1 ± 0.4 Gy, respectively. DVHs and gEUDs for PTV risk , PTV pre c hemo , bladder and intestine revealed minimal differences between the two SIB strategies. Conclusions: Tumor volume reduction for rectal cancer patients following neoadjuvant chemotherapy allows for increased tumor dose using a SIB strategy without increased OAR toxicity.

    Purpose: Hemoglobin levels are currently the focus of interest as prognostic factors in patients with head and neck cancer. Most published clinical trials have confirmed hemoglobin to process a significant influence on survival in patients treated with radiotherapy. In our study we have investigated the prognostic value of hemoglobin in a combined modality schedule. Patients and Methods: Forty-three patients with advanced head and neck tumors were treated with combined radiochemotherapy. The therapy comprised 2 courses of induction chemotherapy with ifosfamide (1,500 mg/m 2 , day 1 to 5) and cisplatin (60 mg/m 2 , day 5) followed by hyperfractionated accelerated radiotherapy with a total dose of only 30 Gy. Surgery involved tumor resection and neck dissection. Results: The 1-year overall survival rate and the 2-year survival rate were 79% and 56%, respectively. The 1- and 2-year recurrence-free survival rates were 68% and 49%, respectively. Prognostic factors with an impact on survival were seen in tumor size (T3 vs T4, p=0.0088), response to radio-chemotherapy at the primary site (no vital tumor rest vs vital tumor rest, p=0.045), response to lymph node radio-chemotherapy (no vital tumor cells vs vital tumor cells, p=0.013) and level of hemoglobin after radio-chemotherapy (Hb≥11.5 g/dl vs [de

    The relationship between surgery, chemotherapy irradiation and the immunological state in patients of laryngeal cancer with or without metastasis was investigated. The lymphocyte reaction to PHA (Phytohaemagglutinin) stimulation and T-lymphocyte count was examined before and immediately after the therapy in 66 patients divided into three groups. From the results the authors conclude that surgical treatment, partial or total laryngectomy, with or without radical Neckdissection influence the immunological state of the patients at least chemotherapy more and irradiation at most.

    To examine survival of women with stage IV uterine carcinosarcoma (UCS) who received neoadjuvant chemotherapy followed by hysterectomy. This is a nested case-control study within a retrospective cohort of 1192 UCS cases. Women who received neoadjuvant chemotherapy followed by hysterectomy based-surgery for stage IV UCS (n = 26) were compared to those who had primary hysterectomy-based surgery without neoadjuvant chemotherapy for stage IV UCS (n = 120). Progression-free survival (PFS) and cause-specific survival (CSS) were examined. The most common regimen for neoadjuvant chemotherapy was carboplatin/paclitaxel (53.8%). Median number of neoadjuvant chemotherapy cycles was 4. PFS was similar between the neoadjuvant chemotherapy group and the primary surgery group (unadjusted-hazard ratio [HR] 1.19, 95% confidence interval [CI] 0.75-1.89, P = 0.45). Similarly, CSS was comparable between the two groups (unadjusted-HR 1.13, 95%CI 0.68-1.90, P = 0.64). When the types of neoadjuvant chemotherapy regimens were compared, women who received a carboplatin/paclitaxel regimen had better survival outcomes compared to those who received other regimens: PFS, unadjusted-HR 0.38, 95%CI 0.15-0.93, P = 0.027; and CSS, unadjusted-HR 0.21, 95%CI 0.07-0.61, P = 0.002. Our study found that there is no statistically significant difference in survival between women with stage IV UCS who are tolerated neoadjuvant chemotherapy and those who undergo primary surgery. © 2017 Wiley Periodicals, Inc.

    A 53 years old mastectomized woman for breast cancer treated with radiotherapy (total doses 12,600 rad) and with long term oral administration of cyclophosphamide (CPM) and ftorafur (FT), developed aplastic anemia and thereafter acute myelogenous leukemia. About six months after discontinuation of the above therapies, she developed anemia and leukopenia and was referred to our clinic. Hematological improvement was obtained by the administration of anabolic hormone, however, two months later she became pancytopenic again. At that time, quite atypical myeloblasts contained peroxidase positive granules, were found 39% in the peripheral blood and 89.4% in the bone marrow, respectively. Leukemic hiatus was present. A bone marrow biopsy revealed coexistence of leukemic cells and breast cancer cells. A diagnosis of breast cancer complicated with acute myelogenous leukemia was made. A combined therapy of adriamycin, CPM and FT was ineffective. OAP regimen of vincristine, cytosine arabinoside and predonisolone revealed transient hematologic improvement. Finally, the patient died of septicemia due to klebsiella. Autopsy revealed wide spread coexistence of leukemia and cancer in the bone marrow, liver, and thyroid. The authors discuss some possible explanations for development of acute leukemia after radiotherapy and chemotherapy.

    Forty-six previously untreated patients with advanced ovarian cancer were treated with combination chemotherapy comprising cisplatin 80 mg m-2 i.v. and cyclophosphamide 1 gm-2 i.v. every 28 days for 5 cycles. Eighty-five percent of patients received more than 75% of the calculated doses, and of 43 evaluable patients, a complete response was achieved in 31 (72%), a partial response in 4 (9.3%) and 8 patients had static or progressive disease. The actuarial survival of the whole group is 60% at a median follow-up of 2 years. Twenty-four patients in complete clinical or pathological remission were then treated with whole abdominal radiotherapy 2,500 cGy followed by a pelvic boost of 2,000 cGy. The pelvic boost was omitted in 3 patients, and the overall radiotherapy treatment time extended in a further 4 patients on account of myelosuppression. The actuarial survival of the 24 patients receiving both treatments at a median of 30 months follow-up is 75%. In the 10 patients with negative second-look procedures completing both treatments there have been no tumour related deaths at a median follow-up of 33 months.

    Selective release of nitric oxide (NO) in tumors could improve the tumor blood flow and drug delivery for chemotherapeutic agents and radiotherapy, thereby increasing the therapeutic index. Glycidyl nitrate (GLYN) is a NO generating small molecule, and has ability to release NO on bioactivation in SCC VII tumor cells. GLYN-induced intracellular NO generation was significantly attenuated by NO scavenger carboxy-PTIO (cPTIO) and NAC. GLYN significantly increases tumor blood flow, but has no effect on the blood flow of normal tissues in tumor-bearing mice. When used with cisplatin, GLYN significantly increased the tumor growth inhibition effect of cisplatin. GLYN also had a modest radiosensitizing effect in vitro and in vivo. GLYN was well tolerated and there were no acute toxicities found at its effective therapeutic doses in preclinical studies. These results suggest that GLYN is a promising new drug for use with chemotherapy and radiotherapy, and provide a compelling rationale for future studies of GLYN and related compounds.

    The need for radiotherapy research is exemplified by the 100,000 cancer patients who will fail treatment locally and/or regionally annually for the next several years but who would benefit from better local treatment modalities. Theoretically, all of the areas of investigation discussed in this projection paper have the potential to significantly improve local-regional treatment of cancer by radiotherapy alone or in combination with other modalities. In many of the areas of investigation discussed in this paper encouraging results have been obtained in cellular and animal tumor studies and in limited studies in humans as well. In the not too distant future the number of patients who would benefit from better local control may increase by tens of thousands if developments in chemotherapy and/or immunotherapy provide a means to eradicate disseminated microscopic foci of cancer. Thus the efforts to improve local-regional control take on even greater significance

    Between 1994 and 2000, 28 patients with T3/T4 squamus cell carcinoma of the maxillary region (maxillary sinus, 22; maxillary gingiva, 4; maxillary bone, 1; buccal mucosa, 1) had accelerated hyperfractionated radiotherapy combined with simultaneous CBDCA chemotherapy preoperatively, at Chiba Cancer Center Hospital. The protocol consisted of combined therapy with accelerated hyperfractionated irradiation of 1.6 Gy, twice a day, to a total dose of 32.0-51.2 Gy and concurrent intra-arterial or intravenous infusion of CBDCA 20-30 mg/body/day for a cumulative total dose of 270-480 mg. After completion of the preoperative combined therapy, the clinical CR rate was 17.9%, and the good PR·CR rate was 32.1%. According to the initial findings and response to the combined therapy, all patients had maxillectomy (subtotal, 3; total, 16; extended, 9) 4 weeks after completion of the preoperative combined therapy. Postoperatively, the complete pathologic response (Ohboshi and Shimozato's classification, grade III and IV) rate was 28.6%. And the actuarial local control rate was 85.7%, with a mean follow-up of 46.2 months. Based on these results, we believe this preoperative therapy with CBDCA chemotherapy and accelerated hyperfractionated radiation is a significant choice as treatment for squamous cell cancer of the maxillary region.

  10. Current concepts of chemotherapy and radiotherapy for small cell lung cancer

    1986-01-01

    Small cell lung cancer (SCLC) was projected to account for 20%-25% of the greater than 140,000 newly diagnosed lung cancers in 1985. If considered a separate disease entity, it would be the fourth leading cause of death by cancer. Previous studies have demonstrated distinct clinical and biologic features of small cell lung cancer, and early therapeutic trial results have demonstrated a high sensitivity to both chemotherapy and radiotherapy. More recent results demonstrated a marked survival improvement with the use of combination chemotherapy, which potentially cured a small minority of patients. Unfortunately, in most patients, drug resistance usually develops, as do chronic, often debilitating toxicities in the few long-term survivors. Although therapeutic advances have plateaued, new and important insights into the basic biology of the disease made the last several years offer the possibility of exciting new treatment approaches within the next decade. This chapter addresses our current understanding of therapy for small cell lung cancer, the current therapy questions under investigation, and potential future directions in clinical research

    Premenopausal women undergoing adjuvant chemotherapy and/or radiotherapy for Breast Cancer (BC) treatment have significant bone loss. This high bone mineral density loss can lead to an increased risk of fractures. In this study, there were evaluated parameters involved in osteoporosis when rats were subjected to a chemotherapy regimen (TC) and/or irradiation (IR). Female Wistar rats were divided into 3 groups: control (G1), TC+IR (G2) and IR (G3). The animals were euthanized after 5 months at the end of treatment and their femurs were excised and dissected. Sections of 10 μm thick were used for μXRF analysis at the National Laboratory of Synchrotron Light. The uteri of these rats were collected and weighed. The obtained results showed that animals from G2 had a significant reduction (pbone composition of the femurs. This same result was notobserved in animals from G1 and G3 groups. These results suggest that early menopause occurs and osteoporosis begins, probably because of the absence, or reduced, production of estrogen. The presence of iron in the G2 samples in indicates the process of osteoporosis, because according to literature, this ion is competitive with calcium ions.

    34 patients operated on for malignant gliomas were successively treated by combination chemotherapy with VM 26 and CCNU and conventional radiation therapy with an average dosage of 5,800 rads, six months after surgery. The general and haematological tolerance of delayed irradiation after chemotherapy was satisfactory. Twelve patients developed neurological complications during or after irradiation. The complications were early in 10 cases, and delayed in 2. They were probably due to tumour growth in five cases, and secondary to irradiation in seven. In four of the seven cases the preradiation chemotherapy seemed to potentiate the radiation effect on the central nervous system. (author)

Sections of 10 μm thick were used for μXRF analysis at the National Laboratory of Synchrotron Light. The uteri of these rats were collected and weighed. The obtained results showed that animals from G2 had a significant reduction (p<0.05) of uterine mass when compared to control. The qualitative analysis performed by μXRF showed that animals from G2 had iron in bone composition of the femurs. This same result was notobserved in animals from G1 and G3 groups. These results suggest that early menopause occurs and osteoporosis begins, probably because of the absence, or reduced, production of estrogen. The presence of iron in the G2 samples in indicates the process of osteoporosis, because according to literature, this ion is competitive with calcium ions. - Highlights: • Premenopausal women undergoing Breast Cancer treatment have significant bone mineral density loss. • Animals submitted to Breast Cancer treatment have their uteri mass decreased. • The µXRF can detect differences in Iron concentration patterns between rats treated, and not treated, with chemotherapy. • Breast Cancer treatment changes the concentration of estrogens, increasing the chances of developing osteoporosis

    This study aimed to assess the effects of body mass index (BMI) on survival in cervical cancer patients who had undergone surgery and radiotherapy (RT). We retrospectively reviewed the medical records of 70 cervical cancer patients who underwent surgery and RT from 2007 to 2012. Among them, 40 patients (57.1%) had pelvic lymph node metastases at the time of diagnosis. Sixty-seven patients (95.7%) had received chemotherapy. All patients had undergone surgery and postoperative RT. Median BMI of patients was 22.8 kg/m2 (range, 17.7 to 35.9 kg/m2). The median duration of follow-up was 52.3 months (range, 16 to 107 months). Twenty-four patients (34.3%) showed recurrence. Local failure, regional lymph nodal failure, and distant failure occurred in 4 (5.7%), 6 (8.6%), and 17 (24.3%) patients, respectively. The 5-year actuarial pelvic control rate was 83.4%. The 5-year cancer-specific survival (CSS) and disease-free survival (DFS) rates were 85.1% and 65.0%, respectively. The presence of pelvic lymph node metastases (n = 30) and being overweight or obese (n = 34, BMI ≥ 23 kg/m2) were poor prognostic factors for CSS (p = 0.003 and p = 0.045, respectively). Of these, pelvic lymph node metastasis was an independent prognostic factor (p = 0.030) for CSS. Overweight or obese cervical cancer patients showed poorer survival outcomes than normal weight or underweight patients. Weight control seems to be important in cervical cancer patients to improve clinical outcomes

    The treatment of the laryngeal carcinoma is controversial in the otolaryngology literature; in glottis cancer that can be managed with radiotherapy, conservative laryngeal surgery and micro-endoscope by laser. At present time, the main objective in the treatment of the early glottis cancer is the control of the tumor and preservation of a good voice. In small injuries, the surgery and the radiotherapy offer equivalent cure rates. The handling of the failure of radiotherapy is controversial; the options go from the resection endoscope with laser, to the total laryngectomy, with local controls [es

    Purpose/Objectives: A prospective single arm trial was undertaken to determine the toxicity, the clinical and pathologic response rates and survival for patients with esophageal cancer treated with concurrent chemotherapy(CC) and accelerated hyperfractionated split course radiotherapy(AHFSCRT) followed by surgical resection. Materials and Methods: A prospective single arm trial was conducted between 1991 and 1995 for patients with T1-4, N0-1, M1(celiac or supraclavicular) adenocarcinoma or squamous cell carcinoma of the esophagus. A total of 74 patients entered onto the protocol, and 72 are eligible and evaluable. Neoadjuvant chemotherapy consisting of two cycles of Cisplatin(20mg/m2/day) and 5-fluorouracil (1000mg/m2/day) given concurrently with AHSCRT 1.5Gy BID (at least 6 hour between fractions) to 2400cGy and 2100cGy, with cycles 1 and 2 of chemotherapy respectively. Patients were staged/restaged with barium esophagram(BS), computerized tomograph of the chest(CAT), upper endoscopy(EGD) with ultrasound (EUS) and evaluated for surgical resection. A single adjuvant course of concurrent chemotherapy and AHSCRT was delivered for those patients who were pathologic partial responders(pPR). Results: Initial clinical staging revealed one patient stage I, 24 patients' stage IIA, 2 patients' with stage IIB, 34 patients' with stage III and 6 patients' with stage IV disease. Five patients could not be staged adequately. The toxicity to neoadjuvant therapy included nausea in 85% (grade 3 in 1%), esophagitis 90% (grade 3 in 18%), neutropenia grade 3 of 43% (with fever 17%), thrombocytopenia grade 4 in 10% and nephrotoxicity in 8%. There was one death due to neoadjuvant therapy. Of the 72 evaluable patients, 67 underwent surgery, and 65(90%) had a complete resection. Twenty-seven percent were pathologic complete responders, including 22% with adenocarcinoma and 36% with squamous cell carcinoma. Complete pathologic response after neoadjuvant therapy was accurately predicted by

    Fifteen patients with advanced, initially inoperable ovarian cancer (stages III and IV) were subjected to second-look surgery between May 1976 and August 1979 following combined radio-chemotherapy. Each case had shown a distinct reduction in tumour size and a demarcation of the foreign issue, which is considered to be prerequisite for second-look surgery. The diagnostic goal of the operation was to verify the success of the preceding radio-chemotherapeutic treatment by means of exact determination of the extent of the residual tumour. The subsequent therapeutic regimen can, if necessary, be modified accordingly. The therapeutic goal is complete surgical removal of the tumour, if at all possible, since the success of subsequent chemotherapy is dependent on the achievement of this aim. The mean interval between initial and second-look surgery was three and a half months. Tumour tissue of varying extent was found in 14 out of 15 cases. In 12 cases total extirpation of the internal genitals was successfully carried out, tumour resection was performed twice, and only of third-look surgery, when after two years of radio-chemotherapy and secondary removal of the internal genitals abdominal tumour diagnosis this patient is now undergoing further chemotherapeutic treatment. We believe that this very case illustrates the importance of second-look surgery and of consistent continuation with radio-chemotherapy in cases of advanced inoperable ovarian cancer. (author)

    The purpose of this retrospective outcome study was to validate the effectiveness of postoperative radiotherapy in breast conserving therapy (BCT) and to evaluate possible causes for omission of radiotherapy after breast conserving surgery (BCS) in a non-trial population. Data were provided by the population-based Munich Cancer Registry. The study included epidemiological data of 30.811 patients diagnosed with breast cancer from 1998 to 2012. The effect of omitting radiotherapy was analysed using Kaplan-Meier-estimates and Cox proportional hazard regression. Variables predicting omission of radiotherapy were analysed using multivariate logistic regression. Use of postoperative radiotherapy after BCS was associated with significant improvements in local control and survival. 10-year loco-regional recurrence-free-survival was 90.8% with postoperative radiotherapy vs. 77.6% with surgery alone (pstudy shows a decrease in local control and a survival disadvantage if postoperative radiotherapy after breast conserving surgery is omitted in an unselected cohort of primary breast cancer patients. Due to its epidemiological nature, it cannot answer the question in whom postoperative radiotherapy can be safely omitted. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Purpose: To determine the outcome and prognostic factors for patients with localized epithelioid sarcoma treated with conservative surgery and radiotherapy (RT). Methods and Materials: The medical records of 24 patients with nonmetastatic epithelioid sarcoma treated with conservative surgery and RT were reviewed. Preoperative RT was given to 3 patients (median 46.4 Gy) and postoperative RT to 21 patients (median 64.5 Gy). A local (limb-sparing) surgical procedure was performed in all patients. Results: At a median follow-up of 131 months, 14 patients had relapsed and 13 patients had died. The actuarial overall and disease-free survival rate at 10 years was 50% and 37%, respectively. Local, nodal, and metastatic failure occurred in 7, 4, and 10 patients, respectively, yielding a 10-year actuarial local, nodal, and metastatic control rate of 63%, 81%, and 56%, respectively. Univariate analysis revealed that size ≤5 cm and extremity location were favorable prognostic factors for overall, disease-free, and metastasis-free survival. The actuarial 5-year overall, disease-free, and metastasis-free survival rate was 79% vs. 25% (p=0.002), 51% vs. 13% (p=0.03), and 79% vs. 13% (p 5 cm. The actuarial 5-year overall, disease-free, and metastasis-free survival rate was 77% vs. 39% (p 0.002), 56% vs. 0% (p=0.01), and 78% vs. 17% (p=0.01), respectively, for extremity vs. nonextremity location. Multivariate analysis of the factors correlating with the overall, disease-free, and metastasis-free survival confirmed the favorable prognostic significance of small lesion size. The prognostic significance of extremity location on univariate analysis was explained by an imbalance in the mean tumor sizes. Conclusions: Epithelioid sarcoma is an aggressive soft-tissue sarcoma, with high rates of local and distant relapse. Local control with conservative surgery and RT compares favorably to published surgical series. The poor outcome for tumors ≥5 cm in size emphasizes the need for

    While surgery is proned in low-grade glioma (LGG), the invasion of functional areas frequently prevents a complete resection. We report the first case of a patient operated on for a left frontal LGG, diagnosed because of seizures, with partial resection due to an invasion of the controlateral hemisphere. Chemotherapy enabled a regression of this controlateral extension. Postchemotherapy surgery performed with intraoperative functional mapping then allowed a complete resection, without sequelae. The patient has a normal socio-professional life, with no seizure. No other treatment was given. There was no recurrence, with a follow-up of 2 years since the second surgery (3.5 years since the first symptom). We propose a new therapeutic strategy in unresectable LGG, with preoperative chemotherapy, to make a radical surgery possible in a second step, while preserving the quality of life.

    Background and purpose: Triple-negative breast cancer (TNBC) presents a high risk breast cancer that lacks the benefit from hormone treatment, chemotherapy is the main strategy even though it exists in poor prognosis. Use of adjuvant radiation therapy, which significantly decreases breast cancer mortality, has not been well described among poor TNBC women. The aim of this study was to evaluate whether the combination of chemotherapy and radiotherapy could significantly increase survival outcomes in TNBC women after mastectomy. Patients and methods: A prospective randomized controlled multi-center study was performed between February 2001 and February 2006 and comprised 681 women with triple-negative stage I-II breast cancer received mastectomy, of them, 315 cases received systemic chemotherapy alone, 366 patients received radiation after the course of chemotherapy. Recurrence-free survival (RFS) and overall survival (OS) were estimated. Simultaneously local and systemic toxicity were observed. Results: After a median follow-up of 86.5 months, five-year RFS rates were 88.3% and 74.6% for adjuvant chemotherapy plus radiation and adjuvant chemotherapy alone, respectively, with significant difference between the two groups (HR 0.77 [95% CI 0.72, 0.98]; P = 0.02). Five-year OS significantly improved in adjuvant chemotherapy plus radiation group compared with chemotherapy alone (90.4% and 78.7%) (HR 0.79 [95% CI 0.74, 0.97]; P = 0.03). No severe toxicity was reported. Conclusions: Patients received standard adjuvant chemotherapy plus radiation therapy was more effective than chemotherapy alone in women with triple-negative early-stage breast cancer after mastectomy.

    Purpose: To investigate the potential gain of the concomitant use of radiotherapy and chemotherapy in improving local control and reducing the need for colostomy, a randomized phase-III trial was performed in patients with locally advanced anal cancer. Material and methods: In the period 1987-1994 110 patients were randomized between radiotherapy alone and a combination of radiotherapy and chemotherapy. The patients had tumors larger than 4 cm, or T 3-4 N 0-3 , or T 1-2 N 1-3 anal cancer. Radiotherapy consisted of 45 Gy given in 5 weeks, with a daily dose of 1.8 Gy. After a rest period of 6 weeks a boost of 15 Gy or 20 Gy was given in case of partial or complete response respectively. Chemotherapy was given during radiotherapy, 750 mg/m2 daily as continuous infusion on day 1-5 and 29-33, a single dose of Mitomycin C 15 mg/m 2 was administered on day 1. Results: The addition of chemotherapy to radiotherapy has resulted in an increase in the complete remission rate from 54% to 80%, and from 83% to 94% if results are considered after surgical resections. This has led to a significant improvement in loco-regional control and colostomy free survival (P=0.04, P=0.003 resp.) both in favor of the combined modality treatment. No significant difference was found when severe side effects were considered. The survival rate remained similar in both treatment arms. Skin ulceration, nodal involvement and sex were the most important prognostic factors for both local control and survival. These remained significant after multivariate analysis. The improvement seen in local control by adding chemotherapy to radiotherapy remained also significant after adjusting for prognostic factors in the multivariate analysis. Conclusions: The concomitant use of radiotherapy and chemotherapy resulted in an improved local control rate and a reduction in the need for colostomy in patients with locally advanced anal cancer

    The authors report a randomized phase II trial which aimed at comparing over three months the laryngeal protection after a TPF-based induction chemotherapy followed by radiotherapy in combination with cisplatin or cetuximab. Over two years, 153 patients have been concerned. The TPF-based induction chemotherapy followed by radiotherapy with cetuximab seems to be the less toxic. A longer monitoring is needed to get better information in terms of laryngeal protection rate, life quality, and laryngeal functionality. Short communication

    The management of ovarian carcinoma is difficult mainly due to the fact that ovary, unlike other organs in the body remains the seat of wide variety of histological type of tumor with even wider biological behaviour and response to each modality of treatment. The objective of present paper is to evaluate the changing policy towards this tumor with emphasis on the combination plan in general and chemotherapy supplement in particular. Prognosis of advanced cancer which forms the bulk of the cases almost in every centre remains dismal. In this group of patients in a retrospective analysis, a guideline of treatment has been formulated. (auth.)

    Purpose: To perform a retrospective review of laryngeal/hypopharyngeal carcinomas treated with concurrent chemotherapy and intensity-modulated radiotherapy (IMRT). Methods and Materials: Between January 2002 and June 2005, 20 laryngeal and 11 hypopharyngeal carcinoma patients underwent IMRT with concurrent platinum-based chemotherapy; most patients had Stage IV disease. The prescription of the planning target volume for gross, high-risk, and low-risk subclinical disease was 70, 59.4, and 54 Gy, respectively. Acute/late toxicities were retrospectively scored using the Common Toxicity Criteria scale. The 2-year local progression-free, regional progression-free, laryngectomy-free, distant metastasis-free, and overall survival rates were calculated using the Kaplan-Meier method. Results: The median follow-up of the living patients was 26 months (range, 17-58 months). The 2-year local progression-free, regional progression-free, laryngectomy-free, distant metastasis-free, and overall survival rate was 86%, 94%, 89%, 92%, and 63%, respectively. Grade 2 mucositis or higher occurred in 48% of patients, and all experienced Grade 2 or higher pharyngitis during treatment. Xerostomia continued to decrease over time from the end of RT, with none complaining of Grade 2 toxicity at this analysis. The 2-year post-treatment percutaneous endoscopic gastrostomy-dependency rate for those with hypopharyngeal and laryngeal tumors was 31% and 15%, respectively. The most severe late complications were laryngeal necrosis, necrotizing fascitis, and a carotid rupture resulting in death 3 weeks after salvage laryngectomy. Conclusion: These preliminary results have shown that IMRT achieved encouraging locoregional control of locoregionally advanced laryngeal and hypopharyngeal carcinomas. Xerostomia improved over time. Pharyngoesophageal stricture with percutaneous endoscopic gastrostomy dependency remains a problem, particularly for patients with hypopharyngeal carcinoma and, to a lesser

    To evaluate whether ABO-Rh blood groups have significance in the treatment response and prognosis in patients with non-metastatic breast cancer. We retrospectively evaluated files of 335 patients with breast cancer who were treated between 2005 and 2010. Demographic data, clinic- pathological findings, treatments employed, treatment response, and overall and disease-free survivals were reviewed. Relationships between clinic-pathological findings and blood groups were evaluated. 329 women and 6 men were included to the study. Mean age at diagnosis was 55.2 years (range: 26-86). Of the cases, 95% received chemotherapy while 70% were given radiotherapy and 60.9% adjuvant hormone therapy after surgery. Some 63.0% were A blood group, 17.6% O, 14.3% B and 5.1% AB. In addition, 82.0% of the cases were Rh-positive. Mean follow-up was 24.5 months. Median overall and progression-free survival times were 83.9 and 79.5 months, respectively. Overall and disease-free survival times were found to be higher in patients with A and O blood groups (pgroup (p=0.226). In univariate and multivariate analyses, ABO blood groups were identified as factors that had significant effects on overall and disease-survival times (p=0.011 and p=0.002). It was seen that overall and disease-free survival times were higher in breast cancer patients with A and O blood groups when compared to those with other blood groups. It was seen that A and O blood groups had good prognostic value in patients with breast cancer.

    Purpose: To compare the outcome of treatment of mediastinoscopy-verified N2 non-small-cell lung cancer treated with induction chemotherapy followed by either surgery or radiotherapy (RT), with both options followed by consolidation chemotherapy. Methods and Materials: A randomized Phase III trial for Stage IIIA (T1-T3N2M0) non-small cell lung cancer was conducted by the Radiation Therapy Oncology Group (RTOG) and Eastern Cooperative Oncology Group between April 1990 and April 1994. After documentation of N2 disease by mediastinoscopy or anterior mediastinotomy, patients received induction chemotherapy with cisplatin, vinblastine, and mitomycin-C. Mitomycin-C was later dropped from the induction regimen. Patients were then randomized to surgery or RT (64 Gy in 7 weeks) followed by cisplatin and vinblastine. Results: RTOG 89-01 accrued 75 patients, of whom 73 were eligible and analyzable. Twelve patients received induction chemotherapy but were not randomized to RT or surgery thereafter. Forty-five patients were randomized to postinduction RT or surgery. Of the analyzable patients, 90% had a Karnofsky performance score of 90-100, 18% had weight loss >5%, 37% had squamous cell histologic features, and 54% had bulky N2 disease. The distribution of bulky N2 disease was uniform among the treatment arms. The incidence of Grade 4 toxicity was 56% in patients receiving mitomycin-C and 29% in those who did not. Only 1 patient in each group had acute nonhematologic toxicity greater than Grade 3 (nausea and vomiting). No acute Grade 4 radiation toxicity developed. The incidences of long-term toxicity were equivalent across the arms. Three treatment-related deaths occurred: 2 patients in the surgical arms (one late pulmonary toxicity and one pulmonary embolus), and 1 patient in the radiation arm (radiation pneumonitis). Induction chemotherapy was completed in 78% of the patients. Complete resection was performed in 73% of 26 patients undergoing thoracotomy. Consolidation

    2002-01-01

    Purpose: To assess the toxicity and efficacy of radiotherapy with respect to locoregional control after adjuvant high-dose chemotherapy for patients with breast cancer. At first, radiotherapy was withheld because of toxicity concerns, but it was introduced in 1995 because of reported high locoregional relapse rates. Methods and Materials: Between 1992 and 1998, 40 patients with Stage II-III high-risk breast cancer received adjuvant high-dose chemotherapy consisting of thiotepa, mitoxantrone, and cyclophosphamide and peripheral blood stem cell support after four cycles of induction chemotherapy. The chest wall or breast, as well as the supraclavicular nodes, were irradiated with electrons and photons to a median dose of 50.4 Gy in 20 patients. Six additional patients received only supraclavicular irradiation to a median dose of 50.4 Gy. Acute toxicity was scored clinically. Pulmonary function tests were performed in 14 irradiated patients before high-dose chemotherapy and 1.1-4.4 years (median 1.6) after irradiation. The median follow-up time of living patients was 33 vs. 67 months in irradiated (n=26) and nonirradiated (n=14) patients, respectively. Results: G2 and G3 hematologic toxicity occurred in 1 patient each. No clinical pneumonitis or clinical impairment of lung function was observed. After 1-2 years, the lung function tests showed only minor changes in 4 patients. The 3-year locoregional control rate was 92% in the irradiated patients vs. 58% in the nonirradiated patients (p=0.049, actuarial analysis). Conclusion: In this series, adjuvant radiotherapy after adjuvant chemotherapy for breast cancer appeared well tolerated, with improved local regional control and without significant side effects. Longer follow-up and more patient accrual, as well as Phase III trials, are necessary for confirmation

    Background and purpose: The role of postoperative chemoradiotherapy in the treatment of patients with gastric cancer with D2 lymph node curative dissection is not well established. In this study, we compared postoperative intensity-modulated radiotherapy plus chemotherapy (IMRT-C) with chemotherapy-only in this patient population. Materials and methods: We randomly assigned patients with D2 lymph node dissection in gastric cancer to IMRT-C or chemotherapy-only groups. The adjuvant IMRT-C consisted of 400 mg of fluorouracil per square meter of body-surface area per day plus 20 mg of leucovorin per square meter of body-surface area per day for 5 days, followed by 45 Gy of IMRT for 5 weeks, with fluorouracil and leucovorin on the first 4 and the last 3 days of radiotherapy. Two 5-day cycles of fluorouracil and leucovorin were given 4 weeks after the completion of IMRT. Chemotherapy-only group was given the same chemotherapy regimens as IMRT-C group. Results: The median overall survival (OS) in the chemotherapy-only group was 48 months, as compared with 58 months in the IMRT-C group; the hazard ratio for death was 1.24 (95% confidence interval, 0.94–1.65; P = 0.122). IMRT-C was associated with increases in the median duration of recurrence-free survival (RFS) (36 months vs. 50 months), the hazard ratio for recurrence was 1.35 (95% confidence interval, 1.03–1.78; P = 0.029). COX multivariate regression analysis showed that lymph node metastasis and TNM stage were both the independent prognostic factors. Rates of all grade adverse events were similar in the two treatment groups. Conclusions: IMRT-C improved RFS, but did not significantly improve OS among patients with D2 lymph node dissection in gastric cancer. Using IMRT plus chemotherapy was feasible and well tolerated in patients with gastric cancer after D2 resection.

    The role of chemotherapy in high-risk soft tissue sarcoma is controversial. Though many patients undergo initial curative resection, distant metastasis is a frequent event, resulting in 5-year overall survival rates of only 50-60%. Neo-adjuvant and adjuvant chemotherapy (CTX) has been applied to achieve pre-operative cytoreduction, assess chemosensitivity, and to eliminate occult metastasis. Here we report on the results of our non-randomized phase II study on neo-adjuvant treatment for high-risk STS. Patients with potentially curative high-risk STS (size ≥ 5 cm, deep/extracompartimental localization, tumor grades II-III [FNCLCC]) were included. The protocol comprised 4 cycles of neo-adjuvant chemotherapy (EIA, etoposide 125 mg/m(2) iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m(2) day 1, pegfilgrastim 6 mg sc day 5), definitive surgery with intra-operative radiotherapy, adjuvant radiotherapy and 4 adjuvant cycles of EIA. Between 06/2005 and 03/2010 a total of 50 subjects (male = 33, female = 17, median age 50.1 years) were enrolled. Median follow-up was 30.5 months. The majority of primary tumors were located in the extremities or trunk (92%), 6% originated in the abdomen/retroperitoneum. Response by RECIST criteria to neo-adjuvant CTX was 6% CR (n = 3), 24% PR (n = 12), 62% SD (n = 31) and 8% PD (n = 4). Local recurrence occurred in 3 subjects (6%). Distant metastasis was observed in 12 patients (24%). Overall survival (OS) and disease-free survival (DFS) at 2 years was 83% and 68%, respectively. Multivariate analysis failed to prove influence of resection status or grade of histological necrosis on OS or DFS. Severe toxicities included neutropenic fever (4/50), cardiac toxicity (2/50), and CNS toxicity (4/50) leading to CTX dose reductions in 4 subjects. No cases of secondary leukemias were observed so far. The current protocol is feasible for achieving local control rates, as well as OS and DFS comparable to previously published

The protocol comprised 4 cycles of neo-adjuvant chemotherapy (EIA, etoposide 125 mg/m2 iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m2 day 1, pegfilgrastim 6 mg sc day 5, definitive surgery with intra-operative radiotherapy, adjuvant radiotherapy and 4 adjuvant cycles of EIA. Result Between 06/2005 and 03/2010 a total of 50 subjects (male = 33, female = 17, median age 50.1 years were enrolled. Median follow-up was 30.5 months. The majority of primary tumors were located in the extremities or trunk (92%, 6% originated in the abdomen/retroperitoneum. Response by RECIST criteria to neo-adjuvant CTX was 6% CR (n = 3, 24% PR (n = 12, 62% SD (n = 31 and 8% PD (n = 4. Local recurrence occurred in 3 subjects (6%. Distant metastasis was observed in 12 patients (24%. Overall survival (OS and disease-free survival (DFS at 2 years was 83% and 68%, respectively. Multivariate analysis failed to prove influence of resection status or grade of histological necrosis on OS or DFS. Severe toxicities included neutropenic fever (4/50, cardiac toxicity (2/50, and CNS toxicity (4/50 leading to CTX dose reductions in 4 subjects. No cases of secondary leukemias were observed so far. Conclusion The current protocol is feasible for achieving local control rates, as well as OS

    Background: A meta-analysis of trials comparing primary treatment with or without chemotherapy for patients with non-small cell lung cancer published in 1995 suggested a survival benefit for cisplatin-based chemotherapy in each of the primary treatment settings studied, but it included many small trials, and trials with differing eligibility criteria and chemotherapy regimens. Methods: The Big Lung Trial was a large pragmatic trial designed to confirm the survival benefits seen in the meta-analysis, and this paper reports the findings in the radical radiotherapy setting. The trial closed before the required sample size was achieved due to slow accrual, with a total of 288 patients randomised to receive radical radiotherapy alone (146 patients) or sequential radical radiotherapy and cisplatin-based chemotherapy (142 patients). Results: There was no evidence that patients allocated sequential chemotherapy and radical radiotherapy had a better survival than those allocated radical radiotherapy alone, HR 1.07 (95% CI 0.84-1.38, P=0.57), median survival 13.0 months for the sequential group and 13.2 for the radical radiotherapy alone group. In addition, exploratory analyses could not identify any subgroup that might benefit more or less from chemotherapy. Conclusions: Despite not suggesting a survival benefit for the sequential addition of chemotherapy to radical radiotherapy, possibly because of the relatively small sample size and consequently wide confidence intervals, the results can still be regarded as consistent with the meta-analysis, and other similarly designed recently published large trials. Combining all these results suggests there may be a small median survival benefit with chemotherapy of between 2 and 8 weeks

  18. The conceptual basis for the combined use of radiotherapy and chemotherapy

    The interactions between drugs and radiation have been observed. In normal tissues, there is evidence both for sensitization and protection, and clear examples of interactive phenomena in tumors do exist. The term ''interaction'' is defined as the situation in which the treatment with one agent modifies the response of cells (tumor or normal) to the treatment with a second agent. Many interactive mechanisms can be envisaged: for instance, drugs modifying the initial events in radiation absorption; repair inhibition; cell-cycle progression phenomena; radiation modifying drug access and drug-induced reoxygenation. ''Spatial cooperation'' is suggested for the situation in which the chemotherapy and radiotherapy given to the diseases in different anatomical sites lead to the therapeutic result that exceeds the results by the separate treatment. The administration of one cytotoxic agent to an animal or a patient would decrease tolerance to the subsequent treatment with another cytotoxic agent. Cytosine arabinoside (Ara-C) is one of the most effective agents. When it was given to mice in a single well-tolerated dose of 200 mg/kg, the proportion of animals that survived wholebody irradiation of 1000 rad was increased from zero to approximately 90%. The timing was critical, and the optimum interval was 2 - 3 days. Under some circumstances, the positive interaction between the tumor cell-killing effects of drugs and radiation can be achieved. Unfortunately, the dose-effect curves are often not linear. (Yamashita, S.)

    Background and purpose: The frequency and grade of pulmonary complications following adjuvant radiotherapy for breast cancer are still debated. This study focuses on loss of pulmonary function. Materials and methods: We have measured the reduction of pulmonary function 5 months following radiotherapy in 144 node-positive stage II breast cancer patients by using pulmonary function tests. Results: No deterioration of pulmonary function was detected among the patients who were treated with local radiotherapy. On the contrary, there was a mean increase in diffusion capacity by 7% (P=0.004) following radiotherapy, which most likely was explained by the adjuvant chemotherapy administered prior to the baseline pulmonary function tests. Patients undergoing loco-regional radiotherapy showed a mean reduction in diffusion capacity by 5% (P<0.001) and in vital capacity by 3% (P=0.001). The subset of patients (9%) who were diagnosed with severe pulmonary complications needing cortisone treatment had significantly larger mean paired differences in vital capacity (-0.446 L, -15% (equivalent to 15 years of normal ageing or the loss of 3/4 of a lung lobe)) compared to the patients who were asymptomatic (-0.084 L) (P<0.05). When the effects of potential confounding factors and different radiotherapy techniques were tested on the reduction of pulmonary function by stepwise multiple regression analysis, a significant correlation was found only to loco-regional radiotherapy including the lower internal mammary lymph nodes. Conclusions: We conclude that a clinically important reduction of pulmonary function is seen in the subset of patients who are diagnosed with severe pulmonary complication following loco-regional radiotherapy for breast cancer. The results of this study warrant further studies based on individual lung dose volume histograms. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

    The purpose was to determine the efficacy and safety of induction chemotherapy followed by concomitant chemoradiotherapy in the treatment of stage III non-small cell lung cancer and whether the response to induction chemotherapy can predict the response to subsequent chemoradiotherapy and survival. In conclusion, there is a statistically significant relationship not only between the response to ICT and the response to CCrt, but also between the response to ICT and the local outcome and survival.

    Purpose: A prospective clinical trial was undertaken to investigate the feasibility of concurrent chemoradiotherapy for the esophageal carcinoma. Materials and Methods: Between June 1989 and May 1996, forty patients with operable squamous cell carcinoma of the thoracic esophagus (stage 0 to III: UICC 1987), aged 45 to 78 (mean:64), were enrolled in a study of neoadjuvant concurrent chemoradiotherapy followed by definitive high-dose radiotherapy (CRT group) or surgery (CRT-S group). Neoadjuvant chemoradiotherapy consisted of 44Gy in 40 fractions for 4 weeks (2.2Gy/2Fr./day) through 10MVX rays, with one or two courses of cisplatin (80-150mg/body, mean:90mg/m 2 , day 1, bolus injection) and 5-fluorouracil (500-1500mg/body/day, mean:600mg/m 2 , day 1-4, continuous infusion). After completion of neoadjuvant chemoradiotherapy, clinical complete response (CR) was observed in 16 patients, partial response (PR) in 22, and no change (NC) in 2. Thirty responding patients (CR:16, PR:14) entered in CRT group, and 10 non-responding patients (PR:8, NC:2) followed by surgery (CRT-S group). A cumulative median dose of 66Gy for Tis,T1 and 71Gy for T2-T4 tumor with/without high-dose-rate intraluminal brachytherapy, and one to three courses of chemotherapy were delivered in CRT group. Intraoperative radiotherapy for abdominal lymphatic system and postoperative supraclavicular irradiation were added in CRT-S group. Results: Clinical CR rate at the completion of treatment showed 90% in CRT group, and pathological CR rate 10% in CRT-S group. The overall median survival was 45 months, survival at 1, 2, 3 years being 100%, 72%, 56%, respectively. Loco-regional failure was observed in 7 patients (all in CRT group), distant failure in 6 (3 in CRT group, 3 in CRT-S group) and loco-regional with distant failure in 1 (CRT group). Four patients of loco-regional recurrence in CRT group were salvaged by surgery. Overall survival at 2-, 3-years for CRT vs. CRT-S group was 72%, 64% vs. (1(1)); 100

    A gastrosplenic fistula is a rare complication of a gastric or splenic lesion. We report a case of Hodgkin's lymphoma (nodular sclerosis) involving the spleen that was complicated by spontaneous gastrosplenic fistula. The fistula was closed laparoscopically and the patient underwent partial gastrectomy and gastric wall repair followed by successful chemotherapy. This is also the first reported case in published literature where the closure of gastrosplenic fistula and partial gastrectomy was carried out laparoscopically. We recommend that extensive open surgical procedures including total gastroectomy, splenectomy and pancreatectomy may be avoided in the management of gastrosplenic fistula and the patient could be managed by less radical, simple laparoscopic fistulectomy, with partial gastric resection. If the fistula is caused by a malignant process, the surgical repair should be followed by definitive treatment with chemotherapy and radiotherapy. (author)

    Laser surgery can control intraoperative hemorrhaging and enable lesions to be accurately removed since, unlike an electrotome, it does not effect electrocontractility. It can also reduce postoperative pain and dysfunction. This study investigated the efficacy of laser surgery in recurrent tongue cancer following radiotherapy. Of the total of 105 patients with squamous cell carcinoma of the tongue (T1, T2N0) who underwent radiotherapy at the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine, at some point between 1980 and 1998, 24 (22.9%) experienced local recurrence. Sixteen of these patients underwent surgical removal of the tumor. Of these 16 patients, 8 (4 early- and 4 late-stage recurrence) had partial glossectomy by laser surgery. Following laser surgery, 2 (1 early- and 1 late-stage recurrence) of the 8 patients died from neck metastasis and another 2 (early-stage recurrence) died from other diseases. The primary and neck tumors are both under control in 3 (late-stage recurrence) of the remaining 4 patients. Laser surgery for late-stage recurrent tongue cancer following radiotherapy appears to be a suitable treatment, although comprehensive glossectomy with/without radical neck dissection is necessary for early-stage recurrent cases after radiotherapy.

    133 Xe-clearance in the branium was measured in order to detect circulatory disturbance following surgery and during and after radiotherapy for breast cancer. In 5 of 10 cases (50%) in which surgery and radiotherapy were performed for breast cancer, lowered circulatory function was noted in the affected side. Lowered function was seen in the non-affected side of the 10 cases in 3 (30%), and normal function was observed in 2 (20%). In 4 of 13 cases (75%), including 3 cases in which radiotherapy was performed, many subjective symptoms were noted. Circulatory function was lowered in 3 of the 4 cases. Generally, cases involving many subjective symptoms were of lowered circulatory function. In the cases in which lowered circulatory function was noted in the non-affected side, there were no subjective symptoms. In all the cases in which radiotherapy was continued or in which radiotherapy had almost been completed, a more or less lowered circulatory function was noted. The onset of lowered function and whether surgery or radiotherapy lowered circulation are unknown. (Ueda, J.)

    Purpose: The influence of radiotherapy in the cosmetic outcome after conservative surgery for breast cancer was evaluated using an objective method of calculating the asymmetry between the two breasts. Methods and Materials: One hundred and one patients treated with the same conservative surgery were evaluated for cosmetic outcome. Sixty-one of them received external radiotherapy (50 + 10 Gy) to the residual breast; the remaining 40 underwent surgery only. The aspect of the patients' breasts was objectively assessed for symmetry by means of a computerized technique. A subjective assessment of the cosmetic outcome was performed both by physician and patient. These objective and subjective assessments were compared in the two groups treated with or without radiotherapy. Results: The results obtained did not show significant differences in terms of cosmetic outcome in the two groups. Skin telangectasia was noted in two radiotherapy patients, while hypertrophic breast scars were only noted in six nonirradiated patients. Conclusions: We found that standard radiotherapy does not seem to influence the symmetry and the cosmetic results in breast conservative treatment when compared to a similar group of patients with the same quadrantectomy procedure and no radiotherapy

    In a randomized trial, patients with inoperable non-small cell lung cancer with limited disease were randomly given either radiotherapy (42 Gy) or combination chemotherapy with cisplatin, 70 mg/m 2 , and etoposide, 100 mg/m 2 , given every third week with a maximum of 4 cycles. The patients were asked to fill in a questionnaire concerning psychosocial well-being, medical and treatment related symptoms, physical function and everyday activity. Of the chemotherapy patients 61% reported nausea 5 weeks after their last chemotherapy session and 44% had spells of vomiting. Only 14% of the radiotherapy patients had nausea and 5% vomited 14 weeks after start of treatment. Of the radiotherapy patients 64% experienced dysphagia compared to 8% of the chemotherapy patients 6 weeks after the start of treatment. (orig.)

    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 Objective To investigate the clinical efficacy of neoadjuvant chemotherapy combined with breast-conserving surgery for locally advanced breast cancer. Methods Eighty-one patients with locally advanced breast cancer were selected from those who were admitted into 309 Hospital of PLA from January 2009 to October 2013, consisting of 65 patients in stage Ⅲa and 16 in stage Ⅲb, and they were treated with neoadjuvant chemotherapy combined with breast-conserving surgery. The clinical efficacy [complete response (CR, partial response (PR, stable disease (SD and progress disease (PD] was observed during follow-up. Results All the patients were followed-up for 12-60 months with a median of 34 months. There were 12 CR patients (14.8%, including 4 with pathological complete response (4.9%, and 52 PR patients (64.2%, 17 SD patients (21.0%. No PD was observed. The overall response rate(ORR was 79.0%(64/81. After follow-up for 12-60 months (median 34 months, distant metastasis to the lung, liver, meninges and bone occurred in 3 patients (3.7%, 3/81 and 1 of them died. Forty-eight patients received breastconserving surgery. The local recurrence rate was 6.3% (3/48. Assessment of cosmetic result was carried out in 48 patients who received breast-conserving surgery and comprehensive treatment for one year, and excellent results were obtained in 14.6% (7/48, good in 43.8% (21/48, and poor in 41.7% (20/48. Conclusions The therapeutic efficacy of locally advanced breast cancer is satisfactory by neoadjuvant chemotherapy and breast-conserving surgery. Standardization of excision and postoperative radiotherapy, systemic comprehensive treatment is the key to the success of the treatment. DOI: 10.11855/j.issn.0577-7402.2015.06.14

    Purpose: To retrospectively analyze results of concurrent chemoradiotherapy (CCRT) using gemcitabine (GEM) for unresectable pancreatic adenocarcinoma. Methods and Materials: Records of 108 patients treated with concurrent external beam radiotherapy (EBRT) and GEM were reviewed. The median dose of EBRT in all 108 patients was 50.4 Gy (range, 3.6-60.8 Gy), usually administered in conventional fractionations (1.8-2 Gy/day). During radiotherapy, most patients received GEM at a dosage of 250 to 350 mg/m{sup 2} intravenously weekly for approximately 6 weeks. After CCRT, 59 patients (54.6%) were treated with adjuvant chemotherapy (AC), mainly with GEM. The median follow-up for all 108 patients was 11.0 months (range, 0.4-37.9 months). Results: Initial responses after CCRT for 85 patients were partial response: 26 patients, no change: 51 patients and progressive disease: 8 patients. Local progression was observed in 35 patients (32.4%), and the 2-year local control (LC) rate in all patients was 41.9%. Patients treated with total doses of 50 Gy or more had significantly more favorable LC rates (2-year LC rate, 42.9%) than patients treated with total doses of less than 50 Gy (2-year LC rate, 29.6%). Regional lymph node recurrence was found in only 1 patient, and none of the 57 patients with clinical N0 disease had regional lymph node recurrence. The 2-year overall survival (OS) rate and the median survival time in all patients were 23.5% and 11.6 months, respectively. Patients treated with AC had significantly more favorable OS rates (2-year OS, 31.8%) than those treated without AC (2-year OS, 12.4%; p < 0.0001). On multivariate analysis, AC use and clinical T stage were significant prognostic factors for OS. Conclusions: CCRT using GEM yields a relatively favorable LC rate for unresectable pancreatic adenocarcinoma, and CCRT with AC conferred a survival benefit compared to CCRT without AC.

  11. Radiotherapy and chemotherapy change vessel tree geometry and metastatic spread in a small cell lung cancer xenograft mouse tumor model.

    Directory of Open Access Journals (Sweden)

    Thorsten Frenzel

    Full Text Available Tumor vasculature is critical for tumor growth, formation of distant metastases and efficiency of radio- and chemotherapy treatments. However, how the vasculature itself is affected during cancer treatment regarding to the metastatic behavior has not been thoroughly investigated. Therefore, the aim of this study was to analyze the influence of hypofractionated radiotherapy and cisplatin chemotherapy on vessel tree geometry and metastasis formation in a small cell lung cancer xenograft mouse tumor model to investigate the spread of malignant cells during different treatments modalities.The biological data gained during these experiments were fed into our previously developed computer model "Cancer and Treatment Simulation Tool" (CaTSiT to model the growth of the primary tumor, its metastatic deposit and also the influence on different therapies. Furthermore, we performed quantitative histology analyses to verify our predictions in xenograft mouse tumor model.According to the computer simulation the number of cells engrafting must vary considerably to explain the different weights of the primary tumor at the end of the experiment. Once a primary tumor is established, the fractal dimension of its vasculature correlates with the tumor size. Furthermore, the fractal dimension of the tumor vasculature changes during treatment, indicating that the therapy affects the blood vessels' geometry. We corroborated these findings with a quantitative histological analysis showing that the blood vessel density is depleted during radiotherapy and cisplatin chemotherapy. The CaTSiT computer model reveals that chemotherapy influences the tumor's therapeutic susceptibility and its metastatic spreading behavior.Using a system biological approach in combination with xenograft models and computer simulations revealed that the usage of chemotherapy and radiation therapy determines the spreading behavior by changing the blood vessel geometry of the primary tumor.

    The purpose of the present paper was to evaluate treatment outcome after conservative breast surgery or mastectomy followed by simultaneous adjuvant radiotherapy and cyclophosphamide, methotrexate and fluorouracil (CMF) therapy. Two hundred and sixty eight (268) patients were treated at two Australian and two New Zealand centres between 1981 and July 1995. One hundred and sixty-nine patients underwent conservation surgery and 99 had mastectomies. Median follow-up was 53 months. Conventionally fractionated radiation was delivered simultaneously during the first two cycles of CMF, avoiding radiation on the Fridays that the intravenous components of CMF were delivered. In conservatively treated patients, 5-year actuarial rates of any recurrence, distant recurrence and overall survival were 34.5 {+-} 5.2%, 25.4 {+-} 4.5% and 75.5 {+-} 4.8%, respectively. Crude incidence of local relapse at 4 years was 6.3% and at regional/distant sites was 26.3%. Highest grades of granulocyte toxicity (< 0.5 x 10{sup 9}/L), moist desquamation, radiation pneumonitis and persistent breast oedema were recorded in 10.7, 8.5, 8.9 and 17.2%, respectively. In patients treated by mastectomy, 5-year actuarial rates of any recurrence, distant recurrence and overall survival were 59.7 {+-} 7.3%, 56.7 {+-} 7.4% and 50.1 {+-} 7%. The crude incidence of local relapse at 4 years was 5.6% and at regional/distant sites it was 45.7%. The issue of appropriate timing of adjuvant therapies has become particularly important with the increasing acknowledgement of the value of anthracycline-based regimens. For women in lower risk categories (e.g. 1-3 nodes positive or node negative), CMF may offer a potentially better therapy, particularly where breast-conserving surgical techniques have been used. In such cases CMF allows the simultaneous delivery of radiotherapy with the result of optimum local control, without compromise or regional or systemic relapse rates.

    A moderate dose of radiation is the recommended treatment for solitary plasmacytoma (SP), but there is controversy over the role of surgery. Our study aimed at comparing different treatment modalities in the management of SP. Data from 38 consecutive patients with solitary plasmacytoma, including 16 with bone plasmacytoma and 22 with extramedullary plasmacytoma, were retrospectively reviewed. 15 patients received radiotherapy alone; 11 received surgery alone, and 12 received both. The median radiation dose was 50Gy. All operations were performed as radical resections. Local progression-free survival (LPFS), multiple myeloma-free survival (MMFS), progression-free survival (PFS) and overall survival (OS) were calculated and outcomes of different therapies were compared. The median follow-up time was 55 months. 5-year LPFS, MMFS, PFS and OS were 87.0%, 80.9%, 69.8% and 87.4%, respectively. Univariate analysis revealed, compared with surgery alone, radiotherapy alone was associated with significantly higher 5-year LPFS (100% vs 69.3%, p=0.016), MMFS (100% vs 51.4%, p=0.006), PFS (100% vs 33.7%, p=0.0004) and OS (100% vs 70%, p=0.041). Radiotherapy alone can be considered as a more effective treatment for SP over surgery. Whether a combination of radiotherapy and surgery improves outcomes requires further study.

    We investigated the clinical significance of apparent diffusion coefficient (ADC) values in diffusion-weighted magnetic resonance imaging (DWI) in monitoring the efficacy of radiotherapy (RT) and chemotherapy (CT) treatments in cervical cancer. In order to identify relevant high quality clinical cohort studies reporting the use of DWI in cervical cancers, the following electronic databases in English and Chinese languages were comprehensively searched: MEDLINE, Science Citation Index database, Cochrane Library Database, PubMed, Embase, CINAHL, and Current Contents Index; Chinese Biomedical Database, Chinese Journal Full-Text Database. All selected studies were published prior to March 2014, and data extracted from these studies were analyzed using STATA 12.0 statistical software. We initially retrieved 196 articles (79 Chinese articles and 117 English articles) through database searches and finally selected sixteen cohort studies for this meta-analysis. The 16 studies contained a combined total of 517 subjects, and all selected studies reported the mean ADC value (10(-3) mm(2)/s) in DWI in cervical cancer patients treated with RT and CT. Combined standardized mean difference (SMD) suggested that the mean post-RT and mean post-CT ADC values were significantly higher than the mean pre-RT and mean pre-CT ADC values, respectively, in cervical cancer patients (SMD=2.95, 95% CI=2.19-3.72, P900 (SMD=2.55, 95% CI=1.78-3.32, P<0.001). The mean ADC value in patients without residual tumor post-RT and post-CT treatment was significantly higher than seen in patients with residual tumors (SMD=0.80, 95% CI=0.49-1.12, P<0.001). Our meta-analysis revealed a significant correlation between mean ADC values and the clinical response to RT and CT treatment. Thus, ADC values in DWI may be effective in evaluating the clinical outcome of treatments in cervical cancer patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    Currently, the most probable theory of tumor surveillance is neither the existence of any tumor-specific, antigen-dependent, T-cell-mediated cytotoxic effect that could eliminate spontaneous tumors in man and that could be used for some kind of vaccination against tumors, nor the complete absence of any surveillance or defense systems against tumors. What is probable is the cooperation of a number of antigen-independent, relatively weakly cytotoxic or possibly only cytostatic humoral and cellular effects, including nutritional immunity, tumor necrosis factor, certain cytokines, and the cytotoxic effects mediated by macrophages, NK cells, NK-like cells, and certain stimulated T-cells. One question remaining to be solved is why these antigen-independent effects do not attack normal cells. A number of plausible hypotheses are discussed. The hypothetical surveillance system is modulated both by traditional cancer treatment and by attempts at immunomodulation. Radiotherapy reduced the T-helper cell function for almost a decade, but not those of macrophages or NK cells. T-cell changes have no prognostic implication, supporting, perhaps, the suggestion of a major role for macrophages and NK cells. Cyclic adjuvant chemotherapy reduces the peripheral lymphocyte population and several lymphocyte functions but not NK activity. Most of the parameters were normalized some years following treatment, but NK activity remained elevated and Th/Ts cell ratio was still decreased. This might possibly be taken to support the surveillance role of NK cells. Bestatin increases the frequency of lymphocytes forming rosettes with sheep red blood cells (but not their mitogenic responses), enhances NK activity, and augments the phagocytic capacity of granulocytes and monocytes (but not their cytotoxic activity). 154 references

    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.

    Impact of p16 protein, a surrogate marker for human papilloma virus induced cancer, p53 and EGFR as well as clinical factors on survival in a patient cohort with oropharyngeal squamous cell carcinoma (OPSCC) treated by surgical resection and adjuvant radiotherapy (RT) ± concomitant chemotherapy (CT). This is a retrospective analysis of patient's charts and tumor tissue. 57 patients were consecutively included and their tumor tissue assembled on a tissue microarray following immunohistochemical analysis. Survival times were estimated by means of Kaplan-Meier analysis. The importance of clinical and immunohistochemical factors for outcome was estimated by cox proportional hazard models. With 88% 5-year overall survival, 91% 5-year disease-specific survival and 91% 5-year disease-free survival, respectively, we found excellent survival rates in this surgically treated patient cohort of mainly advanced OPSCC (93% AJCC stage III or IV). The only factors positively influencing survival were p16 overexpression as well as p53 negativity and even more pronounced the combination of those biomarkers. Survival analysis of patients classified into three risk categories according to an algorithm based on p16, smoking, T- and N-category revealed a low, intermediate and high-risk group with significant survival differences between the low and the high-risk group. Patients with OPSCC can be successfully treated by surgery and adjuvant RT ± CT with a clear survival benefit of p16 positive, p53 negative patients. We recommend considering a combination of immunohistochemical (p16, p53) and clinical factors (smoking, T- and N-category) for risk stratification.

    In spite of the progress made in neoadjuvant therapy for operable non small-cell lung cancer (NSCLC), many issues remain unsolved, especially in locally advanced stage IIIA. Retrospective data of 163 patients diagnosed with stage IIIA NSCLC after surgery was analyzed. The patients were divided into two groups: a preoperative chemotherapy group including 59 patients who received platinum-etoposide doublet treatment before surgery, and an upfront surgery group including 104 patients for whom surgical resection was the first treatment step. Adjuvant chemotherapy or/and radiotherapy was administered to 139 patients (85.3%), while 24 patients (14.7%) were followed-up only. The rate of N2 disease was significantly higher in the upfront surgery group ( P   0.05). There was significant difference in preoperative chemotherapy group regarding relapse rate and treatment outcomes related to the lymph node status comparing to the upfront surgery group. Neoadjuvant/adjuvant chemo-therapy is a part of treatment for patients with stage IIIA NSCLC, but further investigation is required to determine optimal treatment. © 2017 The Authors.

    Aims: High local failure rates in gastric cancer have been reported, up to 67%. To achieve a better local control, we evaluated intraoperative radiotherapy (IORT) and external beam radiotherapy (EBRT) in association with surgery for gastric cancer patients with lymph node involvement. We report here the analysis of the patterns of failure for patients involved in this IORT protocol. Material and methods: Forty-two positive lymph node (N+) gastric cancer patients were operated on (31 total, three subtotal and eight extended gastrectomies) with IORT procedure between 1985 and 1997 (33 males, nine females, mean age 61.3 years). IORT was focused on coeliac area (mean dose 15 Gy), followed by EBRT (46 Gy) in 36 patients. Ten patients were pN1 and 32 were pN2. A concurrent systemic chemotherapy (five Fluoro-Uracil and Cisplatinum) was performed in 14 patients. Results: One patient died postoperatively. Actuarial pN+ 10 year survival rate was 44.8%. The 5 year actuarial local control and disease-free survival rates were 78.8 and 47.5%, respectively. As far as patterns of failure were explored, 5 patients have a local coeliac recurrence (12%) and 12 have distant metastases with no evidence of coeliac recurrence. Conclusion: This retrospective analysis suggests a potential effect of IORT and/or EBRT in promoting local control and long-term survival in gastric cancer patients with lymph node involvement

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    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)

    The application of induction chemotherapy failed to provide a consistent benefit for local control in primary treatment of advanced head and neck (H&N) cancers. The aim of this study was to compare the results of concomitant application of radiochemotherapy for treating locally advanced head-and-neck carcinoma in comparison with the former standard of sequential radiochemotherapy. Between 1987 and 1995 we treated 122 patients with unresectable (stage IV head and neck) cancer by two different protocols. The sequential protocol (SEQ; 1987–1992) started with two courses of neoadjuvant chemotherapy (cisplatin [CDDP] + 120-h continuous infusions (c.i.) of folinic acid [FA] and 5-fluorouracil [5-FU]), followed by a course of radiochemotherapy using conventional fractionation up to 70 Gy. The concomitant protocol (CON; since 1993) combined two courses of FA/5-FU c.i. plus mitomycin (MMC) concomitantly with a course of radiotherapy up to 30 Gy in conventional fractionation, followed by a hyperfractionated course up to 72 Gy. Results from the two groups were compared. Patient and tumor characteristics were balanced (SEQ = 70, CON = 52 pts.). Mean radiation dose achieved (65.3 Gy vs. 71.6 Gy, p = 0.00), response rates (67 vs. 90 % for primary, p = 0.02), and local control (LC; 17.6% vs. 41%, p = 0.03), were significantly lower in the SEQ group, revealing a trend towards lower disease-specific (DSS; 19.8% vs. 31.4%, p = 0.08) and overall (14.7% vs. 23.7%, p = 0.11) survival rates after 5 years. Mucositis grades III and IV prevailed in the CON group (54% versus 44%). Late toxicity was similar in both groups. Concurrent chemotherapy seemed more effective in treating head and neck tumors than induction chemotherapy followed by chemoradiation, resulting in better local control and a trend towards improved survival

    The results of treatment of infants with medulloblastoma using surgery and chemotherapy, without the use of radiation therapy, are reported. Both survival and outcome, in terms of growth, neurologic deficit, and intelligence are compared with the same parameters in children treated conventionally. Although preliminary, our results suggest that chemotherapy combined with surgery is a valid option for the treatment of infants with this type of neoplasm.

    Intravesical instillation of glycosaminoglycans is a promising option for the treatment of chronic cystitis, as it supports the regeneration of the damaged urothelial layer. We investigated the efficacy of short-term intravesical chondroitin sulphate treatment (six courses of instillation) in patients with chronic radiotherapy- or chemotherapy-associated cystitis. This prospective, observational study included patients with chronic radiotherapy- or chemotherapy-associated cystitis, who received six once-weekly intravesical instillations of 0.2% chondroitin sulphate 40 mL. Every week, patients recorded their symptoms and their benefits and tolerance of treatment, using a self-completed questionnaire. The study included 16 patients (mean age 68.5 years; 50% male). During the study, a reduction in all evaluated parameters was observed. After one dose of chondroitin sulphate, symptom improvement was observed in 38% of patients, and after the second dose, an additional 31% of patients showed improvement. At week 6, 80% of patients had either improved or were symptom free, and significant improvements in urinary urgency (p = 0.0082), pollakisuria (p = 0.0022), urge frequency (p = 0.0033) and lower abdominal pain (p = 0.0449) were observed. Haematuria, present in 9 of the 16 patients at baseline, was completely resolved in all cases after 6 weeks. The majority of patients (93%) evaluated the tolerance of chondroitin sulphate as 'good' or 'very good'. No treatment-related adverse events were reported. Intravesical administration of chondroitin sulphate was effective for the treatment of radiotherapy- or chemotherapy-associated cystitis. Even short-term treatment appears to be effective in reducing symptoms and improving the quality of life of patients.

    Purpose/Objective: This phase II study has been conducted to determine the feasibility, toxicity, response rate, local control, distant metastasis, and survival of hyperfractionated 3D conformal radiotherapy and concurrent chemotherapy with mitomycin C, vinblastine, and cisplatin in unresectable stage III non-small cell lung cancer (NSCLC), and also to find the most ideal 3D conformal radiotherapy technique. Materials and Methods: From Aug 1993, 173 patients with unresectable stage III NSCLC were entered into this trial and 146 (84%) completed the treatment. Hyperfractionated radiotherapy was given to a total dose of 65-70 Gy (120 cGy/fx, bid) with concurrent 2 cycles of MVP chemotherapy (Mitomycin C 6 mg/m 2 d2 and d29, Vinblastine 6 mg/m 2 d2 and d29, Cisplatin 60 mg/m 2 d1 and d28). Of these 146 patients who completed the treatment, 78 received noncoplanar 3D conformal radiotherapy using 4-6 fields and 17 received coplanar segmented conformal radiotherapy. Clinical tumor response was assessed one month after the completion of radiotherapy by computerized tomography (CT) scan. Toxicity was graded by RTOG and SWOG criteria. Normal tissue complication probability (NTCP) for lung was calculated to find the correlation with radiation pneumonitis. Results: Nineteen (13%) had stage IIIa and 127 (87%) had IIIb disease including 16 with pleural effusion and 20 with supraclavicular lymph node metastases. Response rate was 74%, including 20% complete response and 54% partial response. With a minimum follow up of 12 months, overall survival was 60% at 1 year, 30% at 2 years and median survival was 15 months. Patients achieving a complete response (n=29) had a 2-year overall survival of 46.5% compared to 28.7% for partial responders (n=79) (p=.001). Actuarial local control was 66.7% at 1 year and 43.7% at 2 years. Actuarial distant free survival was 52.3% at 1 year and 39.8% at 2 years. Major hematologic toxicity (Gr 3-4) occurred in 33% of the patients but treatment delay

    Complemental radiotherapy during surgery for ensuring radical removal of multi-invasive and multicentric tumors is an acknowledged principle. Irradiation under the operation permits pin-pointed application of a high, single radiation dose to a sharply defined target area, while movable radiosensitive organs can be optimally protected. The requirements of this treatment call for close interdisciplinary collaboration of surgeons and radiooncologists. Due to the demand for highly experienced personnel and sophisticated technology, application of this type of radiotherapy is restricted so far to a few medical centers. The value of the treatment was analysed and proven by an international multi-center study performed by experienced hospitals. The CD-ROM in hand presents a topical survey of ongoing activities, techniques and developments relating to radiotherapy during surgery at the national and international level and is intended to serve as a source of information and further learning for colleagues wishing to specialize in this field.

    Neoadjuvant chemoradiotherapy (CTRT) is the current standard of care for treatment of locally advanced cancer of the esophagus or gastroesophageal junction. Many efforts have been made over the last years to identify the best chemotherapy and radiotherapy combination regimen, but specific randomized trials addressing this issue are still lacking. Areas covered: A systematic review of the literature was performed searching in PubMed all published studies of combinations CTRT regimens for operable or unresectable esophageal cancer to describe activity and toxicity. Studies considered were prospective series or clinical phase II-III trials including at least 40 patients and published in English language. Expert commentary: Long-term results of CROSS trial have established RT combined with carboplatin plus paclitaxel chemotherapy as the preferred neoadjuvant treatment option for both squamous and adenocarcinoma of the esophagus. More effective multimodal treatment strategies integrating novel biological agents including immunotherapy and based on an extensive molecular tumor characterization are eagerly awaited.

    Although the technical developments of radiotherapy have been remarkable, there are currently few reports on the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as initial treatment in this three-dimensional conformal radiotherapy era. Thus, we retrospectively evaluated the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as the initial treatment. Thirty-two patients who underwent radiotherapy were enrolled in this study. The dose per fraction was 2.0–3.5 Gy. Because the treatment schedule was variable, the biological effective dose (BED) was calculated. Local control (LC) and overall survival (OS) rates from the completion of radiotherapy were calculated. The 1-, 2-, 3-, 4-, and 5-year LC rates were 51.5%, 24.5%, 19.6%, 19.6%, and 13.1%, respectively. LC rates were significantly higher for the high BED group (≥75 Gy10) than for the lower BED group (<75 Gy10). All patients who reported pain achieved pain relief. The duration of pain relief was significantly higher for the high BED group than for the lower BED group. The 1-, 2-, 3-, 4-, and 5-year OS rates were 82.6%, 56.5%, 45.2%, 38.7%, and 23.2%, respectively. There was a trend toward higher OS rates in with higher BED group compared to lower BED group. For patients with unresectable locally recurrent rectal cancer treated with surgery alone, radiotherapy is effective treatment. The prescribed BED should be more than 75 Gy10, if the dose to the organ at risk is within acceptable levels.

    Dysphagia is the earliest and the most common symptom of malignant disease in the esophagus. The palliative effects on dysphagia of radiotherapy (RT) and chemotherapy (CT) were evaluated retrospectively and compared with the effect of the self-expanding stent, evaluated in the prospective study. After completion of treatment, 78 (56%) of 140 patients treated with RT; 31 (49%) of 63 patients treated with CT; and 53 (81%) of 66 patients treated with stent insertion were free from dysphagia. Stent treatment has a good and prompt effect on dysphagia and can be recommended for palliation of patients with malignant esophageal strictures. (orig.).

    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.

    Purpose: this study was undertaken to evaluate the efficacy of two regimens of chemoradiotherapy in the treatment of locally advanced head and neck cancer. Methods: from 1992 to 1997, 127 patients with locally advanced head and neck cancer (stage III-IV) were randomized. Sixty-six patients (group a), 42 male and 24 female, with a median age of 48 years (range 40-72) received during radiotherapy two courses (1.-6. week) of chemotherapy with carbo-platin (300 mg/m{sup 2} day 1) and etoposide (60 mg/m{sup 2} days 1 to 3). Sixty-one patients (group b), 40 male and 21 female, with a median age of 51 years (range 42-69) received two cycles of chemotherapy with 5 FU (750 mg/m{sup 2} days 1 to 5) and MIT C ( 10 mg/m{sup 2} day 1). The median dose of radiotherapy was 60 Gy (range 55-66 Gy) 180 cGy /d 5w. Results: the actuarial five-year survival rate(Kaplan-Meier) was 38 % for group a (CBDCA+etoposide+RT) and 25 % for group b (5FU+MIT C+RT). The difference was statistically significant (p = 0.036). Toxicity group a: mucositis G III in 41 patients and G IV in 16; dysphagia G III in 46 patients and IV in 5; leukopenia in 24 patients; 28 patients required nutritional therapy. Toxicity group b: mucositis G III in 38 patients and G IV in 17; dysphagia G III in 48 patients and G IV in 3; leukopenia in 23 patients; 25 patients needed nutritional therapy. Conclusions: the data of the actuarial survival five-year rate suggest that concomitant chemotherapy in group a (CBDCA+etoposide+RT) is better than the concomitant chemotherapy in group b (5FU+MIT C+RT).

    .105). Conclusions:Patients with MIBC who overexpress Ki-67 and with negative hormonal receptors have relatively substantial risk of relapse within the first five years after surgery. However, adjuvant chemotherapy can only improve the outcomes of ER(-)/PR(-) patients, but not those who overexpress Ki-67. Further studies with prolonged follow-up of large cohorts are recommended to assess the prognostic significance and treatment of this lesion.

    To assess the therapeutic outcome and failure pattern of three-dimensional conformal radiotherapy (3D-CRT)-based concurrent chemoradiotherapy (CCRT) for recurrence of esophageal squamous cell carcinoma (SCC) after radical surgery. Treatment outcome and failure pattern were retrospectively evaluated in 83 patients with localized cervical and thoracic recurrences after radical surgery for thoracic esophageal SCC. All patients were treated with 3DCRT-based CCRT (median radiation dose 60 Gy), in which 39 received concurrent cisplatin plus 5-fluorouracil (PF), and 44 received concurrent docetaxel plus cisplatin (TP). Treatment response was evaluated at 1–3 months after CCRT. With a median follow-up of 34 months (range, 2–116 months), the 3-year overall survival (OS) of all the patients was 51.8% and the median OS time was 43.0 months. The overall tumor response rate was 75.9% (63/83), with a complete remission (CR) rate of 44.6% (37/83). In univariate analysis, tumor response after CCRT (p = 0.000), recurrence site (p = 0.028) and concurrent chemotherapy (p = 0.090) showed a trend favoring better OS. Multivariate analysis revealed that tumor response after CCRT (p = 0.000) and concurrent chemotherapy (p = 0.010) were independent predictors of OS. Forty-seven patients had progressive diseases after CCRT, 27 had local failure (27/47, 57.4%), 18 had distant metastasis (18/47, 38.3%) and 2 had both local and distant failures (2/47, 4.3%). 3DCRT-based CCRT is effective in postoperatively recurrent esophageal SCC. Patients that obtained complete remission after CCRT appeared to achieve long-term OS and might benefit from concurrent TP regimen. Local and distant failures remained high and prospective studies are needed to validate these factors

    Background: Multiple concepts of combined modality therapy for locally advanced inoperable non-small cell lung cancer have been investigated. These include induction chemotherapy, concomitant chemo-radiotherapy, and radiation only. To date, combined modality therapy specially the use of concomitant chemo-radiotherapy has led to promising results and was shown to be superior to radiotherapy alone in phase II studies. However the optimum chemo-therapeutic regimen to be used as well as the benefit of induction chemotherapy before concomitant chemo-radiotherapy are yet to be determined. Based on these observations, we investigated the use of paclitaxel and carboplatin concomitantly with radiotherapy and the benefit of prior two cycles induction chemotherapy. Materials and Methods: In this trial 50 patients with locally advanced inoperable non small cell lung cancer, good performance status and minimal weight loss have been randomized into 3 groups each of 20 patients. Group A received induction 2 cycles paclitaxel (175 mg/m 2 ) and carboplatin (AUC 6) on day I and 28 th followed by concomitant paclitaxel (45 mg/m 2 ) and carboplatin (AUC 2) weekly with radiotherapy. Group B received concomitant carboplatin, paclitaxel (same doses as in group A) and radiotherapy with no prior induction chemotherapy. Group C received only radiotherapy to a total dose of 60 Gy in conventional fractionation. Results: A total of 60 patients were enrolled in this study between 1998 and 2000. Pretreatment characteristics, including age, gender, performance status, histological features and stage were comparable in each group. The incidence of oesophagi tis was significantly higher in group A and B than in group C (ρ=0.023). Hematological toxicities was also significantly higher in group A and B than in group C (ρ=0.003). The response rate was significantly higher in group A and B than in group C (75%,79%, and 40% respectively) (ρ =0.020). The time to in-field progresion was significantly

    Purpose: to evaluate the outcome of hyperfractionated-accelerated radiotherapy and subsequent planned primary tumor resection and radical neck dissection in locally advanced tumors of the oral cavity. Patients and Methods: this retrospective analysis evaluates 126 subsequent patients who were treated between 1988 and 1997 for locally advanced tumors of the oral cavity (with extension into the oropharynx in 17 patients), 34 (27%) AJCC stage III and 92 (73%) stage IV. Primary tumor and nodal metastases were irradiated with 1.4 Gy bid to a median total dose of 72.8 Gy (range 58.8-75.6 Gy). Then, planned radical surgery of the primary site according to the initial tumor extent and cervical nodes was performed. Median follow-up of living patients was 6 years (range 1-11 years). Results: 4 weeks after radiotherapy, 14 patients (11%) had complete tumor remission, 92 (73%) partial remission, 15 (12%) no change, and five (4%) progressive disease. Complete resection was achieved in 117 (93%) patients (nine incomplete resections). 5-year locoregional control rate was 62 ± 9%, overall survival 36 ± 9%. Surgery-related morbidity occurred in 42 patients (33%; mainly delayed wound healing and fistulae), overall severe treatment-related morbidity in 46 patients (36%). 24/84 relapse-free patients (29%) required a percutaneous gastrostomy or nasal tube ≥ 1 year after therapy. Conclusion: in this study, the outcome of combined curative radiotherapy and planned surgery of the primary tumor and neck nodes was comparable to reported results of hyperfractionated radiotherapy with or without salvage surgery of the neck nodes with respect to locoregional control and overall survival. Planned surgery carries a substantial risk of morbidity and seems to offer no benefit in comparison to salvage surgery of the neck nodes only. Therefore, salvage surgery is preferred. (orig.)

    Ninety-one patients with histologically proven anaplastic carcinoma of the thyroid were referred to the Beatson Oncology Centre between 1961 and 1986. The female:male ratio was 2.4:1 and the median age at presentation was 70 (range 38-92) years. All patients had a thyroid mass at presentation and the most common symptoms were dyspnoea, dyspnagia and dysphonia. Five patients had a total thyroidectomy and 28 partial thyroidectomy. Ninety five per cent of patients received external beam radiotherapy. Results show dyspnoea to be the only symptom strongly influencing survival. Total or partial thyroidectomy is associated with increased survival. This association is most marked for patients presenting without dyspnoea. Eighty per cent of patients responded to radiotherapy.

    To report our experience with increased dose intensity-modulated radiation and concurrent systemic chemotherapy as definitive treatment of locally advanced esophageal cancer. We analyzed 27 consecutive patients with histologically proven esophageal cancer, who were treated with increased-dose IMRT as part of their definitive therapy. The majority of patients had T3/4 and/or N1 disease (93%). Squamous cell carcinoma was the dominating histology (81%). IMRT was delivered in step-and-shoot technique in all patients using an integrated boost concept. The boost volume was covered with total doses of 56-60 Gy (single dose 2-2.14 Gy), while regional nodal regions received 50.4 Gy (single dose 1.8 Gy) in 28 fractions. Concurrent systemic therapy was scheduled in all patients and administered in 26 (96%). 17 patients received additional adjuvant systemic therapy. Loco-regional control, progression-free and overall survival as well as acute and late toxicities were retrospectively analyzed. In addition, quality of life was prospectively assessed according to the EORTC QLQs (QLQ-OG25, QLQ-H&N35 and QLQ-C30). Radiotherapy was completed as planned in all but one patient (96%), and 21 patients received more than 80% of the planned concurrent systemic therapy. We observed ten locoregional failures, transferring into actuarial 1-, 2- and 3-year-locoregional control rates of 77%, 65% and 48%. Seven patients developed distant metastases, mainly to the lung (71%). The actuarial 1-, 2- and 3-year-disease free survival rates were 58%, 48% and 36%, and overall survival rates were 82%, 61% and 56%. The concept was well tolerated, both in the clinical objective examination and also according to the subjective answers to the QLQ questionnaire. 14 patients (52%) suffered from at least one acute CTC grade 3/4 toxicity, mostly hematological side effects or dysphagia. Severe late toxicities were reported in 6 patients (22%), mostly esophageal strictures and ulcerations. Severe side effects to

    Full Text Available Breast-conserving surgery followed by whole-breast irradiation is the standard local therapy for early breast cancer. The international discussion of reduced importance of wider tumor-free resection margins than “tumor not touching ink” leads to the development of five principles in targeted oncoplastic breast surgery. IORT improves local recurrence risk and diminishes toxicity since there is less irradiation of healthy tissue. Intraoperative radiotherapy (IORT can be delivered in two settings: an IORT boost followed by a conventional regimen of external beam radiotherapy or a single IORT dose. The data from TARGIT-A and ELIOT reinforce the conviction that intraoperative radiotherapy during breast-conserving surgery is a reliable alternative to conventional postoperative fractionated irradiation, but only in a carefully selected population at low risk of local recurrence. We describe our experiences with IORT boost (50 kV energy X-rays; 20 Gy in combination with targeted oncoplastic breast surgery in a routine clinical setting. Our experiences demonstrate the applicability and reliability of combining IORT boost with targeted oncoplastic breast surgery in breast-conserving therapy of early breast cancer.

    We update Radiation Therapy Oncology Group trial 8911 (USA Intergroup 113), a comparison of chemotherapy plus surgery versus surgery alone for patients with localized esophageal cancer. The relationship between resection type and between tumor response and outcome were also analyzed. The chemotherapy group received preoperative cisplatin plus fluorouracil. Outcome based on the type of resection (R0, R1, R2, or no resection) was evaluated. The main end point was overall survival. Disease-free survival, relapse pattern, the influence of postoperative treatment, and the relationship between response to preoperative chemotherapy and outcome were also evaluated. Two hundred sixteen patients received preoperative chemotherapy, 227 underwent immediate surgery. Fifty-nine percent of surgery only and 63% of chemotherapy plus surgery patients underwent R0 resections (P = .5137). Patients undergoing less than an R0 resection had an ominous prognosis; 32% of patients with R0 resections were alive and free of disease at 5 years, only 5% of patients undergoing an R1 resection survived for longer than 5 years. The median survival rates for patients with R1, R2, or no resections were not significantly different. While, as initially reported, there was no difference in overall survival for patients receiving perioperative chemotherapy compared with the surgery only group, patients with objective tumor regression after preoperative chemotherapy had improved survival. For patients with localized esophageal cancer, whether or not preoperative chemotherapy is administered, only an R0 resection results in substantial long-term survival. Even microscopically positive margins are an ominous prognostic factor. After a R1 resection, postoperative chemoradiotherapy therapy offers the possibility of long-term disease-free survival to a small percentage of patients.

    The aim of this study was to evaluate the efficacy and complications of self-expandable metallic stent placement for patients with inoperable esophageal carcinoma after radiotherapy and/or chemotherapy. We obtained data from 19 patients with advanced or recurrent esophageal carcinoma between 1996 and 2000. In all patients, a self-expandable metallic stent was placed under fluoroscopic guidance. Dysphagia before and after stent placement was graded. Complications after stent placement were also evaluated. Data were compared between patients with and without prior radiotherapy and/or chemotherapy. The procedure was technically successful in all but one patient. The dysphagia grade improved in all patients. No life-threatening complications occurred. The other major complications such as mediastinitis occurred in two patients, and pneumonia and funnel phenomenon occurred in one patient each. These patients had a history of radiotherapy and/or chemotherapy prior to stent placement. Eight of the twelve patients with prior radiotherapy and/or chemotherapy compared with one of seven patients without prior therapy had persistent chest pain, which was a statistically significant difference (P<0.05). Placement of self-expandable metallic stents was effective for patients with advanced or recurrent esophageal carcinoma. However, prior irradiation and/or chemotherapy increased the risk of persistent chest pain after stent placement. (author)

    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.

    Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with radiotherapy only at sites distant from the ovaries (chest wall, thigh, and leg) had minimal menstrual irregularities or temporary cessation of menses during therapy; cyclic menses returned promptly after therapy. Gonadotropin levels (expressed as means +/- SD) [follicle-stimulating hormone (FSH), 10 +/- 15 mlU/ml; luteinizing hormone (LH), 10 +/- 4 mlU/ml] and 17 β-estradiol (E 2 ) levels (means +/- SD, 208 +/- 147 pg/ml) were normal. By contrast, 4 older women (ages 36-43 yr) who received similar treatment developd persistent amenorrhea with postmenopausal levels of gonadotropin (FSH, 109 +/- 29 mlU/ml; LH, 72 +/- 19 mlU/ml) and E 2 (19 +/- 8 pg/ml). Two additional women (ages 21 and 39 yr) who received radiation (7000 rad) to the pelvis plus chemotherapy developed prompt cessation of menses and became functional castrates (FSH, 77 and 80mlU/ml; LH, 40 and 58 mlU/ml; E 2 , 10 and 19 pg/ml). However, this result would be expected from the radiation dose alone. The data demonstrated that ovarian dysfunction may follow the use of doxorubicin, cyclophosphamide, and high doses of methotrexate and that the injury is age related

    Fifty patients with invasive bladder carcinoma were treated with neoadjuvant intra-arterial chemotherapy using doxorubicin or pirarubicin, and this was combined with low dose radiotherapy. All of 50 patients were evaluated for clinical and histological efficacy. Twenty-nine of 50 (58%) patients achieved a clinically complete remission (CR) and 17 of 50 (34%) achieved a clinically partial remission (PR). Twenty-eight of 50 (56%) achieved a histological CR and 13 of 50 (26%) achieved a histological PR. The patients who underwent bladder preservation operations after this treatment and were followed up for longer than 3 years were evaluated for long-term results. The 5-year survival for 35 patients in this group was 74.1%. The 5-year survival for patients with a clinical CR was 93.3%, and for patients with a clinical PR it was 45.3%. The survival for patients with a histological CR was 93.3%, and for patients with a histological PR, it was 85.7%. This study suggests that neoadjuvant intra-arterial chemotherapy plus radiotherapy is a useful regimen that could become the treatment of first choice for patients with invasive bladder carcinoma. Patients who achieved a histological CR or PR with this regimen, might be able to retain the function of their bladders. (author)

    Decision analysis was used to evaluate the results of treatment of T 2 N 0 M 0 glottic carcinoma as presented in the literature. Based on mean values for recurrence, salvage eligibility after recurrence and salvage success, the 5-year survival after radiotherapy and surgery proved to be almost identical, 85 and 86%. If the recurrence rates and the salvage rates were varied, a marginal advantage for surgery in small tumours and a major advantage in more extended tumours was seen if only survival is considered. To take the quality of speech into account, a utility analysis was performed. A utility scale was defined ranging from 0.0 as the value for death, to 1.0 for a successfully irradiated patient with preservation of normal speech. A utility of 0.99 or less for the laryngectomized patient would favour radiotherapy over surgery for all T 2 tumours. In patients with T 2b tumours and in extreme circumstances, e.g. if failure rates of radiotherapy are extremely low, an exact assessment of patient utilities may be pivotal. Under normal circumstances radiotherapy is preferred for T 2 N 0 M 0 glottic carcinoma if both survival and the quality of speech are taken into account. (author). 39 refs.; 5 figs.; 1 tab

    Objective: To study the cosmetic outcome and curative effect of 6 MV X-ray tangential field radiotherapy for early stage breast cancer after conservative surgery. Methods: The eligible criteria were single tumor ≤3 cm in diameter, surgical margin negative and lymph node negative. The exclusive criteria were inflammatory carcinoma or male breast cancer. After conservative surgery, 42 patients with stage 0, I or II breast cancer were treated with conventional radiotherapy with a total dose of 50 Gy to the whole breast and 10 Gy boost to the tumor bed. The efficacy and the cosmetic outcome of radiotherapy were evaluated every 3 months for the first 2 years and every 6 months after that and every 12 months after 5 years. Results: The follow up time was 19-90 months (median 56 months). Two patients died of metastasis after 16 months and 36 months, which was diagnosed by CT scan. Excellent or good cosmetic outcome was > 93% at 36 months. The local control rate was 100%. The 1- and 3-year survival rates was 100% and 98%, respectively. Conclusions: Tangential field radiotherapy for early breast cancer after conservative surgery has a satisfied result in both tumor control and cosmetic outcome, which can definitely improve the life quality of the patients.

    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.

    The interest in accelerated partial breast irradiation (PBI) after conservative surgery has increased over the past decade as a result of many factors, including clinical and pathological data questioning the efficacy of whole breast irradiation in highly selected patients, as well as factors related to patient's convenience. High dose rate and low dose rate brachytherapy, brachytherapy MammoSite, Electron Intraoperative Therapy - ELIOT and Targeted Intraoperative Radiotherapy - TARGIT are the subject of investigation. The tolerability and efficacy of the treatment are of special interest. In this review article, methods of accelerated PBI, eligibility criteria, techniques of radiotherapy, early results and side effects are reviewed. (author)

    The incidence of peritoneal carcinomatosis of colorectal cancer amounts to 5%-15% for synchronous metastases and as much as 40% in cases of local recurrence. Best results are obtained for cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC). This treatment offers much better outcomes, leading to 5-year survival rates of as much as 30%-50%. The procedures require significant experience in abdominal surgery, are time-consuming (mean duration of the procedure ranging from 6 to 8 hours) and are burdened by complications that are due not only to the procedure itself but also to the intraperitoneal administration of the cytostatic drug at elevated temperature (41.5 °C). After the procedure, patients are required to be admitted to intensive care units due to potential complications associated with the extent and duration of the procedure as well as chemotherapy administered in hyperthermia. Postoperative management of these patients requires appropriate experience of the entire medical and nursing team. Cytoreductive surgeries combined with HIPEC as highly specialized medical procedures should be assessed for their potential long-term benefits and their costs should be appropriately calculated with consideration to realistic reimbursement rates. Realistic valuation and reimbursement covering the overall average cost of the procedure is recommended by the National Consultant in Surgical Oncology as well as the ESMO consensus guidelines.

    The growing number of patient reports of angina and myocardial infarction during cancer management prompted this review of coronary artery disease (CAD) in cancer patients. There is no definite evidence that cancer per se nor any particular tumor type predisposes to coronary atherosclerosis. Cardiac metastases can cause CAD via tumor emboli, extrinsic compression, or ostial obstruction; in these patients the diagnosis of CAD as a result of cardiac metastases often is not made until death. The course of these patients usually is fulminant. Tumor-associated coagulation disorders and non-bacterial thrombotic endocarditis can cause coronary thromboemboli; treatment should be initiated early as these patients often are not in a terminal state when such CAD develops. Post-radiation CAD seen in experimental animals (via fibrosis and/or accelerated atherogenesis) can be extrapolated to the clinical situation. This is best evidenced by 10 young patients, with minimal coronary risk factors in most, who developed angina and/or myocardial infarction 2 to 100 months after chest radiotherapy; approximate mediastinal doses ranged from 1440 Roentgen to 5075 rad. In 5 patients there was no significant atherosclerosis beyond the radiation portals; 2 had successful saphenous vein bypass grafts. Lipid-lowering therapy may prevent post-radiotherapy atherogenesis in high risk individuals. Chemotherapy (acting directly or synergistically with radiotherapy) has caused angina and myocardial infarction within hours to days after the infusion of agents both classically cardiotoxic as well as others, although the exact mechanism(s) for coronary artery damage as a result of chemotherapy presently is unknown.

    To describe our experience with cisplatin- and paclitaxel-based IP chemotherapy in patients treated initially with either neoadjuvant chemotherapy and interval debulking surgery (IDS) or primary cytoreductive surgery (PCRS). We performed a retrospective review of the records of 67 patients (38 IDS, 29 PCRS) enrolled in the intraperitoneal (IP) chemotherapy program at the Tom Baker Cancer Centre between 2006 and 2009. Information pertaining to patient demographics, IP chemotherapy toxicity, and catheter complications was extracted, and the median time to recurrence was calculated. Most patients in the study were aged 50 to 70 years and had a diagnosis of stage III serous ovarian cancer. Overall, 295/393 IP cycles (75%) were successfully administered. The proportion of patients completing six cycles of chemotherapy in the IDS and PCRS groups was 53% and 59%, respectively. Frequent (> 25%) Grade 1 to 2 chemotherapy toxicities included fatigue, peripheral neuropathy, and nausea. Catheter complications were observed in 34% of patients (23/67). The recurrence rates for patients completing four or more cycles of IP chemotherapy in the IDS and PCRS groups were 58% and 35%, respectively, with the median time to recurrence approximately one year. Although IP chemotherapy is well tolerated in both IDS and PCRS patients, the median time to recurrence is shorter than expected.

    The aim of this paper is to evaluate the efficacy of surgery for patients with oral cavity or oropharyngeal cancer, and is impact on the final results of treatment combined with postoperative radiotherapy. Furthermore, predictive and prognostic value of clinical and histopatological postoperative factors were analysed, and estimation of clinical applicability of modified scale for risk of postoperative local and/or nodal recurrence according to Peters was checked. Material includes 218 cases of the advanced oral cavity or oropharyngeal cancer. All data were subdivided into 4 groups depending on treatment strategy. For the analysis of the treatment efficacy (overall and disease-free survival) many predictive and prognostic factors have been considered. Despite of multivariate logistic regression analysis of these factors, the risk of local recurrence was related to the results of combined treatment based on the modified numerical risk scale adapted from Peters. The risk value is the sum of scores given to individual prognostic factors. Time interval between surgery and radiotherapy (TI) and overall treatment time (TTT) have been accounted for the analysis. Generally; optimal results were noted in the group B, where surgery has been combined with postoperative radiotherapy. In case of surgery combined with preoperative radiotherapy (group E) 5-year DFS was 30%, and in the case when radiotherapy was delayed and applied when recurrence after primary surgery has occurred, the 5-year DFS was not higher than 20%. Macro- and microscopic surgical radicalism has been found one of the most important and significant prognostic factors. For positive margins (m+) 5-year DFS significantly decreases to about 20%. Surgical macro- and microradicalism has an important impact (p = 0.013) on the incidence of distant metastases. The scoring system for the recurrence was based on Peters scale. The sum of the risk scores (TRRI+n) for individual prognostic factors allow to allocate

    N-stage is related to distant metastasis of nasopharyngeal carcinoma (NPC) patients. We performed this study to compare the efficacy of different chemotherapy sequences in advanced N-stage (N2 and N3) NPC patients treated with intensity modulated radiotherapy (IMRT). From 2001 to 2008, 198 advanced N-stage NPC patients were retrospectively analyzed. Thirty-three patients received IMRT alone. Concurrent chemoradiotherapy (CCRT) was delivered to 72 patients, neoadjuvant chemotherapy (NACT) + CCRT to 82 patients and CCRT + adjuvant chemotherapy (AC) to 11 patients. The 5-year overall survival rate, recurrence-free survival rate, distant metastasis-free survival rate and progress-free survival rate were 47.7% and 73.1%(p<0.001), 74.5% and 91.3% (p = 0.004), 49.2% and 68.5% (p = 0.018), 37.5% and 63.8% (p<0.001) in IMRT alone and chemoradiotherapy group. Subgroup analyses indicated that there were no significant differences among the survival curves of CCRT, NACT + CCRT and CCRT + AC groups. The survival benefit mainly came from CCRT. However, there was only an improvement attendency in distant metastasis-free survival rate of CCRT group (p = 0.107) when compared with RT alone group, and NACT + CCRT could significantly improve distant metastasis-free survival (p = 0.017). For advanced N-stage NPC patients, NACT + CCRT might be a reasonable treatment strategy

    Purpose: To determine the effects of sequential versus concurrent administration of cranial radiotherapy and cisplatin/carmustine (BCNU) chemotherapy on survival and toxicity in newly diagnosed high-grade astrocytomas. Methods and Materials: From 1988 to 1996, 101 patients were treated on 2 therapeutic protocols for malignant glioma that used the identical chemotherapy regimen but differed in the timing of cranial radiotherapy. The eligibility criteria for the 2 protocols were identical. In the first protocol (1988-1991, 52 patients), cisplatin 120 mg/BCNU 120 mg i.v. over 72 h, was given for 3 monthly cycles prior to cranial radiotherapy. After a response rate of 42%, with a median survival of 13 months was achieved with this sequential regimen, a successor protocol (1992-1996, 49 patients) was developed in which cranial radiotherapy began concurrently with the start of the identical chemotherapy regimen. Chemotherapy was delayed but not discontinued if prolonged grade III/IV hematologic toxicity was experienced, but protocol therapy was discontinued if disease progression or thromboembolic events occurred. Survival outcome and hematologic toxicity were compared for the patients treated on these protocols. Results: Seventy-seven percent of sequentially-treated patients and 68% of concurrently-treated patients completed all planned therapy. Kaplan-Meier survival was similar to concurrent or sequential administration of chemotherapy and radiotherapy (median 12.8 months vs. 13.8 months, respectively). Hematologic toxicity was significantly less in sequentially- versus concurrently-treated patients, with median nadir per cycle (2.9 vs. 1.8 x 10 3 /mm 3 ) (p < 0.001), and incidence of grade 3/4 leukopenia 40% versus 77% (p = 0.002). There was also an increase in platelet transfusion requirements in concurrently-treated patients, but no significant worsening of anemia. We postulate that the worsened leukopenia results from the effects of concurrent radiotherapy on

    The present study was designed to analyze cervical cancer cells treated with radiotherapy or intraarterial infusion of CDDP using image analysis. Total nuclear extinction (TE), 5 N-exceeding rate (5 NER) and nuclear area (NA) gradually increased following irradiation, in cervical cancer cases. TE and 5 NER increased markedly following radiotherapy in good response cases. TE, 5 NER and NA were not-changed following irradiation in poor response cases. 5 NER, in good prognostic cases was higher than in poor prognostic cases, significantly among cervical cancer cases treated with radiotherapy. 5 NER and NA increased dramatically in good response cases treated with intraarterial infusion of CDDP.

    2012-01-01

    Background: In non-small cell lung cancer (NSCLC) stage III, data on patient reported health-related quality of life (HRQL) are scarce, especially regarding concurrent chemoradiotherapy. Aims: To evaluate HRQL in patients treated with high dose radiotherapy combined with concurrent chemotherapy or the antibody cetuximab. Methods: The study population comprised all patients enroled in either of two phase II trials in locally advanced NSCLC performed in Sweden 2002–2007. The RAKET trial investigated three different ways of increasing local control (accelerated hyperfractionated treatment or concurrent daily or weekly chemotherapy). The Satellite trial evaluated the addition of cetuximab to thoracic irradiation. HRQL was measured at four time points: At baseline, before radiotherapy, 4–6 weeks after radiotherapy and at 3 months follow-up, using the EORTC QLQ-C30 and LC14 set of questionnaires. Results: 154/220 patients (65%) who completed HRQL assessments at all time points were included in the longitudinal study. There was a significant decline over time regarding most functioning measures. Dyspnoea and fatigue gradually deteriorated without recovery after completed treatment. Chemotherapy related symptoms showed a transient deterioration, whereas radiotherapy related esophagitis had not fully recovered at 3 months. Patients with stage IIIA disease tended to recover better regarding global QL, fatigue and dyspnoea compared to patients with stage IIIB. Patients with WHO performance status (PS) 0 reported improved global QL and less fatigue over time compared with PS 1. Concurrent chemotherapy was associated with more pronounced fatigue and dysphagia, and worse global QL compared with concurrent cetuximab. Baseline physical functioning was an independent predictor of overall survival. Conclusion: Patients undergoing high dose thoracic radiotherapy combined with chemotherapy or cetuximab reported a gradual deterioration in functioning, dyspnoea and fatigue, while

    Conclusions: Longer follow-up still does not show a significant difference in OS and LRFS between both treatments. Because most patients submitted to surgery required adjuvant RT and since its side-effects were not negligible, further studies are warranted to better suit the first treatment for each patient and to prevent the need for adjuvant treatment and the risk of toxicity.

    A 38-year-old woman with early stage invasive breast cancer was treated with wide excision of the tumor, axillary lymph node dissection, and breast irradiation. Three years later, she gave birth to a normal baby. She attempted breast feeding and had full lactation from the untreated breast. The irradiated breast underwent only minor changes during pregnancy and postpartum but produced small amounts of colostrum and milk for 2 weeks postpartum. There are only a few reports of lactation after breast irradiation. These cases are reviewed, and possible factors affecting breast function after radiotherapy are discussed. Because of scant information available regarding its safety for the infant, nursing from the irradiated breast is not recommended

    The Adenoid Cystic Carcinoma (ACC) or Cilindroma is a strange entity classified by the WHO within the carcinomas of salivary glands. It represents only 1 % of all the wicked tumours of the oral and maxillofacial region although, when making reference to the salivary glands, it constitutes 5% of the parotid, submaxilar and sublingual carcinomas, and about 50% of the smallest ones. The most frequent location is in the palatine glands and its main characteristics are: slow but persistent growth, high rates of local relapse and metastasis at distance originating the death between the first 5 and 10 years in 50-70% of the cases approximately. A case of localization is presented in sublingual gland which was first treated surgically and later with radiotherapy, obtaining good results. (author) [es

    Full Text Available Background: The impact of postoperative radiotherapy (PORT on outcomes has been a matter of debate after adequate resection in Ewing's sarcoma of the pelvis. We evaluated our cases after surgical excision in pelvic Ewing's sarcoma and assessed local control and overall survival (OS with respect to PORT and chemotherapy-induced percentage necrosis. Materials and Methods: Forty four surgically operated patients (June 2002–November 2014 of localized Ewing's sarcoma were retrospectively reviewed. There were 31 males and 13 females. Age ranged from 2 to 53 years. All patients received institutional chemotherapy protocol. No patient received preoperative radiotherapy. Specimen was analyzed for margins and chemotherapy-induced percentage necrosis. PORT was offered to patients on case-by-case basis. Presence of a large preoperative soft-tissue component, margin evaluation, and percentage necrosis were factors considered. At time of the last followup, 29 patients were alive, 11 died, and 4 were lost to followup. Survivors had a minimum followup of 2 years (range: 31–118 months, mean = 69 months. Results: One of twenty (5% patients with PORT had a local recurrence as against 2 of 24 (8% without PORT. OS of all patients was 76% at 5 years. Twelve patients with 90% necrosis had OS of 83% (P = 0.040. OS of patients with PORT was 74%, without PORT was 78% (P = 0.629. Conclusions: The decision to offer PORT after surgical excision in pelvic Ewing's sarcoma is multifactorial; the absence of PORT in selected cases is not detrimental to local control. Poor responders to chemotherapy had poorer survival while PORT did not impact on outcomes.

One of twenty (5%) patients with PORT had a local recurrence as against 2 of 24 (8%) without PORT. OS of all patients was 76% at 5 years. Twelve patients with 90% necrosis had OS of 83% ( P = 0.040). OS of patients with PORT was 74%, without PORT was 78% ( P = 0.629). The decision to offer PORT after surgical excision in pelvic Ewing's sarcoma is multifactorial; the absence of PORT in selected cases is not detrimental to local control. Poor responders to chemotherapy had poorer survival while PORT did not impact on outcomes.

    The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0–50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease-free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively. Adjuvant radiotherapy was performed according to risk factors and stage IB, grade 3 and lymphovascular invasion were observed more frequently in the EBRT group. Five-year DFS for EBRT and VB alone were 88.1% and 96.0%, respectively (p = 0.42), and 5-year OS for EBRT and VB alone were 94.4% and 96%, respectively (p = 0.38). There was no locoregional recurrence in any patient. Two patients who received EBRT and 1 patient who received VB alone developed distant metastatic disease. Two patients who received EBRT had severe complications, one each of grade 3 gastrointestinal complication and pelvic bone insufficiency fracture. Adjuvant radiotherapy achieved high DFS and OS with acceptable toxicity in stage I endometrial cancer. VB (with a lower dose per fraction) may be a viable option for selected patients with early-stage endometrial cancer following surgery.

    Purpose: The aim of this Phase II study was to examine whether concurrent continuous infusion 5-fluorouracil (CI 5FU) plus three-dimensional conformal planning radiotherapy sandwiched between gemcitabine chemotherapy is effective, tolerable, and safe in the management of pancreatic cancer. Methods and Materials: Patients were enrolled in two strata: (1) resected pancreatic cancer at high risk of local relapse (postsurgery arm, n = 22) or (2) inoperable pancreatic cancer in head or body without metastases (locally advanced arm, n = 41). Gemcitabine was given at 1,000 mg/m 2 weekly for 3 weeks followed by 1 week rest then 5-6 weeks of radiotherapy and concurrent CI 5FU (200 mg/m 2 /day). After 4 weeks' rest, gemcitabine treatment was reinitiated for 12 weeks. Results: For the two arms combined, treatment-related Grade 3 and 4 toxicities were reported by 25 (39.7%) and 7 (11.1%) patients, respectively. No significant late renal or hepatic toxicity was observed. In the postsurgery arm (R1 54.5%), median time to progressive disease from surgery was 11.0 months, median time to failure of local control was 32.9 months, and median survival time was 15.6 months. The 1- and 2-year survival rates were 63.6% and 31.8%. No significant associations between outcome and mutations in K-ras or TP53 or microsatellite instability were identified. Post hoc investigation of cancer antigen 19-9 levels found baseline levels and increases postbaseline were associated with shorter survival (p = 0.0061 and p < 0.0001, respectively). Conclusions: This three-dimensional chemoradiotherapy regimen is safe and promising, with encouraging local control for a substantial proportion of patients, and merits testing in a randomized trial

    Details with regard to the standard criteria for a therapeutic metastasectomy and the use of video-assisted thoracic surgery (VATS) remain elusive. To evaluate the feasibility of VATS using a tailor-made virtual lung for patients with pulmonary metastases after chemotherapy, we reviewed the following cases. Clinical data from October 2006 to April 2010 were obtained from patients who received chemotherapy before a pulmonary metastasectomy (lobectomy or segmentectomy). VATS was the primarily selected surgical approach except for treating hilar lesions. A lobectomy was performed when the metastasis was greater than 3.0 cm in diameter or located deeply in the lobe. Tailor-made virtual lungs were created using three-dimensional multidetector computed tomography before lobectomy on a routine basis. The virtual lung consisted of three-dimensional pulmonary vessels, a tracheobronchial tree, pulmonary parenchyma, and tumors. Twelve operations, consisting of 1 segmentectomy, 10 lobectomies, and 1 wedge bronchoplasty upper lobectomy, were performed on 11 patients during the study period. VATS was completed in 10 of these 12 operations. The mean operative time for the lobectomies was 257 min, and the mean operative bleeding volume was 215 ml. Two cases experienced postoperative transient atrial fibrillation, and no mortalities associated with these operations were reported. VATS was performed safely in instances of metastasectomy after chemotherapy, and the tailor-made virtual lung assisted in lung orientation during the operation. (author)

    Purpose: To describe the technique and results of stereotactically guided conformal radiotherapy (SCRT) in patients with craniopharyngioma after conservative surgery. Methods and materials: Thirty-nine patients with craniopharyngioma aged 3-68 years (median age 18 years) were treated with SCRT between June 1994 and January 2003. All patients were referred for radiotherapy after undergoing one or more surgical procedures. Treatment was delivered in 30-33 daily fractions over 6-6.5 weeks to a total dose of 50 Gy using 6 MV photons. Outcome was assessed prospectively. Results: At a median follow-up of 40 months (range 3-88 months) the 3- and 5-year progression-free survival (PFS) was 97% and 92%, and 3- and 5-year survival 100%. Two patients required further debulking surgery for progressive disease 8 and 41 months after radiotherapy. Twelve patients (30%) had acute clinical deterioration due to cystic enlargement of craniopharyngioma following SCRT and required cyst aspiration. One patient with severe visual impairment prior to radiotherapy had visual deterioration following SCRT. Seven out of 10 patients with a normal pituitary function before SCRT had no endocrine deficits following treatment. Conclusion: SCRT as a high-precision technique of localized RT is suitable for the treatment of incompletely excised craniopharyngioma. The local control, toxicity and survival outcomes are comparable to results reported following conventional external beam RT. Longer follow-up is required to assess long-term efficacy and toxicity, particularly in terms of potential reduction in treatment related late toxicity

    We have developed an intraoperative radiotherapy technique in breast-conserving surgery. Following lumpectomy and axillary dissection up to Level II, the subcutaneous fat layer was lifted from the gland over the entire breast. Electron beams of 25 Gy were irradiated within cylinder, avoiding the skin and subcutaneous tissue. The surface of the gland was covered with cotton swabs saturated with normal saline to equalize the energy depth to the chest wall. This technique has so far been applied to 8 patients, all of whom went through a successful postoperative period without serious complications. The cosmetic results were satisfactory from immediately after the operation. Intraoperative radiotherapy combined with breast-conserving surgery may be helpful in improving the QOL of patients by eliminating the adverse effects associated radiation injury to the skin of the breast and long-term postoperative follow-up.

    To compare the long-term outcomes in patients with salivary gland adenoid cystic carcinoma (SGACC) treated with post-operative chemoradiotherapy (POCRT) versus post-operative radiotherapy (PORT). We retrospectively reviewed the records of 91 SGACC patients treated with surgery followed by PORT (n = 58) or POCRT (n = 33) between 2000 and 2013. Treatment outcomes between groups were compared using propensity score matching (1:1 nearest neighbor). The median radiation dose was 66 Gy, and patients were followed up for a median of 71 months. Cisplatin-based concurrent regimens were the most commonly used chemotherapy schedules. In the entire study cohort, patients undergoing POCRT showed a trend toward higher locoregional control (LRC) rates than those treated with PORT alone at both 5 and 8 years (97 and 97 % versus 84 and 79 %, respectively; P = .066). Distant metastases were the most common form of treatment failure and occurred in 31 (34 %) patients (PORT, n = 17; POCRT, n = 14). After propensity score matching (33 pairs), patients receiving POCRT had 5- and 8 year LRC rates of 97 and 97 %, respectively, compared with 79 and 67 % for patients treated with PORT alone (P = .017). The two groups did not differ significantly in terms of distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS). However, a significantly better opioid-requiring pain-free survival (ORPFS) was achieved in POCRT group (P = .038). Subgroup analyses revealed that patients with stage III − IV disease (P = .040 and .017), positive surgical margins (P = .011 and .050), or perineural invasion (P = .013 and .035) had significantly higher 5- and 8 year LRC and ORPFS when treated with POCRT, respectively. In SGACC patients, adding concurrent chemotherapy to PORT may increase LRC and ORPFS rates, particularly in presence of stage III − IV disease, positive surgical margins, or perineural invasion. However, no significant differences in DMFS, DFS, and OS were

    Purpose: To examine psycho-social and geographic determinants of delay in starting radiotherapy in early invasive breast cancer patients. Material and methods: Waiting time was defined as the time elapsed until the beginning of radiotherapy, starting from the date of surgery (in absence of chemotherapy) or from the end of chemotherapy. Results: Eight hundred and ninety six women aged 24-89 took part in the study. Mean waiting times were 52 days (sd = 19) between surgery and radiotherapy and 31 days (sd = 14) between chemotherapy and radiotherapy. Differences between radiotherapy centres (p < 0.0001) accounted for 30% and 12%, respectively, of total variance in waiting times. Using a multivariate mixed analysis that took into account intra-centre correlation, the time between surgery and radiotherapy was shorter for young patients (p = 0.020), those who had sought information about their illness (p = 0.024) and those who had undergone surgery and radiotherapy in the same centre (p = 0.021). On the other hand, no patient characteristic was associated with the time between chemotherapy and radiotherapy. Conclusion: Centre is the major factor that explained longer waiting times in radiotherapy, emphasising the structural hypothesis. It is important to pursue initiatives to improve the organization within radiotherapy centres and then to verify that these initiatives have succeeded in shortening waiting times.

    Purpose: To compare the efficacy of intra-arterial chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder transitional cell carcinoma (BTCC) followed by bladder-preserving surgery. Materials and Methods: Sixty patients with T1G3 BTCC were randomly divided into two groups. After bladder-preserving surgery, 29 patients (age 30-80 years, 24 male and 5 female) received intra-arterial chemotherapy in combination with intravesical chemotherapy (group A), whereas 31 patients (age 29-83 years, 26 male and 5 female) were treated with intravesical chemotherapy alone (group B). Twenty-nine patients were treated with intra-arterial epirubicin (50 mg/m{sup 2}) + cisplatin (60 mg/m{sup 2}) chemotherapy 2-3 weeks after bladder-preserving surgery once every 4-6 weeks. All of the patients received the same intravesical chemotherapy: An immediate prophylactic was administered in the first 6 h. After that, therapy was administered one time per week for 8 weeks and then one time per month for 8 months. The instillation drug was epirubicin (50 mg/m{sup 2}) and lasted for 30-40 min each time. The end points were tumour recurrence (stage Ta, T1), tumour progression (to T2 or greater), and disease-specific survival. During median follow-up of 22 months, the overall survival rate, tumour-specific death rate, recurrence rate, progression rate, time to first recurrence, and adverse reactions were compared between groups. Results: The recurrence rates were 10.3 % (3 of 29) in group A and 45.2 % (14 of 31) in group B, and the progression rates were 0 % (0 of 29) in group A and 22.6 % (7 of 31) in group B. There was a significant difference between the two groups regarding recurrence (p = 0.004) and progression rates (p = 0.011). Median times to first recurrence in the two groups were 15 and 6.5 months, respectively. The overall survival rates were 96.6 and 87.1 %, and the tumour-specific death rates were 0 % (0 of 29) and 13.5 % (4 of 31

    A 68 year-old man was given a diagnosis of lung cancer of the right upper lobe (small cell carcinoma, T 4 N 2 M 0, stage IIIB) in February 1991. The tumor diminished after chemotherapy and radiotherapy. In February 1992, a partial resection of the lower lobe of the right lung was performed because of the appearance of a metastatic tumor. In September 1994, squamous cell carcinoma developed in the lower part of the esophagus, but disappeared after radiotherapy. In February 1998, a diagnosis of myelodysplastic syndrome was made. Two months later, the patient had an attack of acute myelocytic leukemia and died of cardiac tamponade. An autopsy determined that both the lung cancer and esophageal cancer had disappeared. Acute myelocytic leukemia and plasmacytoma of lymph nodes in the irradiated area were confirmed. These were regarded as secondary malignancies induced by chemotherapy and radiotherapy. (author)

    The coexistence of pregnancy and cancer is a challenging situation for the physician. Chemotherapy and radiotherapy are often necessary, depending on the type and stage of cancer at diagnosis. When applying such treatment, several key points concerning the health of the fetus must be carefully monitored. Meanwhile, if the appropriate treatment is delayed until postpartum, the mother's life may be at risk. Historically, the mother's health was placed above that of the fetus. This concept has changed, and harmonization of maternal and fetal health is now considered ideal. Numerous reports have shown the safe use of chemotherapy especially during the second and third trimesters of pregnancy. In 2004 our department treated seven cases of simultaneous cancer and pregnancy, leading us to review the use of chemotherapy and radiotherapy during pregnancy and the repercussions on neonatal outcome.

    Malignant craniopharyngioma or anaplastic craniopharyngioma was first reported in 1987 by Akachi. It has a malignant clinical and histological feature; remarkably rapid progression, atypical pathology like squamous cell carcinoma and poor prognosis. To date seventeen cases of malignant craniopharyngioma have been reported and of these cases, most were of secondary malignant tumor in nature. With respect to traditional benign craniopharyngioma, adjunctive treatment after gross total removal is not necessary, but in the case of malignant types of the tumor, adjunctive treatment is important. This paper presents the first case of malignant craniopharyngioma reactive to adjunctive Gamma knife stereotactic radiosurgery and chemotherapy. Malignant craniopharyngioma is very rare, and we report Gamma knife stereotactic radiosurgery and chemotherapy (Carboplatine and etoposide chemotherapy), as well as Temozolomide chemotherapy were effective and could control progression of the tumor temporarily. Since adjunctive Gamma knife stereotactic radiosurgery and chemotherapy of malignant craniopharyngioma cases affects follow-up strategies, we propose supporting the need to a revision to the WHO classification regarding malignancy evaluation of craniopharyngioma.

    Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with radiotherapy only at sites distant from the ovaries (chest wall, thigh, and leg) had minimal menstrual irregularities or temporary cessation of menses during therapy; cyclic menses returned promptly after therapy. Gonadotropin levels (expressed as means +/- SD) (follicle-stimulating hormone (FSH), 10 +/- 15 mlU/ml; luteinizing hormone (LH), 10 +/- 4 mlU/ml) and 17 ..beta..-estradiol (E/sub 2/) levels (means +/- SD, 208 +/- 147 pg/ml) were normal. By contrast, 4 older women (ages 36-43 yr) who received similar treatment developd persistent amenorrhea with postmenopausal levels of gonadotropin (FSH, 109 +/- 29 mlU/ml; LH, 72 +/- 19 mlU/ml) and E/sub 2/ (19 +/- 8 pg/ml). Two additional women (ages 21 and 39 yr) who received radiation (7000 rad) to the pelvis plus chemotherapy developed prompt cessation of menses and became functional castrates (FSH, 77 and 80mlU/ml; LH, 40 and 58 mlU/ml; E/sub 2/, 10 and 19 pg/ml). However, this result would be expected from the radiation dose alone. The data demonstrated that ovarian dysfunction may follow the use of doxorubicin, cyclophosphamide, and high doses of methotrexate and that the injury is age related.

    Aims of this study were to avoid staging laparotomy, to improve the results of radiotherapy (RT) alone by a combined modality approach, to evaluate the optimal extent of RT after short-term chemotherapy (CT) and to reduce the long-term toxicity in patients cured for ESHD. From (2(90)) to (1(95)), 110 consecutive patients with clinical stage I (bulky and/or B), IIA, IIA bulky and IIEA entered a randomized trial comparing subtotal nodal irradiation (STNI) vs involved field radiotherapy (IFRT), both after short-term chemotherapy (ABVD for 4 cycles). The doses of RT were 30 Gy to uninvolved and 36 Gy to involved sites, respectively. With a median follow-up of 38 mos., the main results in 96 evaluable patients (stage I: 13 pts., stage II: 83 pts., median age 28 yrs., range 17-64) are as reported below. Most patients achieved complete remission (CR) after CT (92%), while 8 partial responders attained CR with RT (IFRT 5 pts., STNI 3 pts.). Four stage II patients relapsed (IFRT 2, pts., STNI 2 pts.), mainly in extranodal or not irradiated sites. Up-to-date the most remarkable toxicities include: acute myocardial infarction (1%), aspecific EKG changes (5%), reductions in pulmonary function tests (most mild and/or transient) in 45%, subclinical or clinical hypothyroidism 26% (only in pts. irradiated to the neck), 3 cases of azoospermia in 23 evaluable patients (13%) and transient amenorreha in(1(44)) patients. No second malignancies have been so far observed. The results of this study seem to indicate that 4 courses of ABVD plus RT are an effective treatment in clinical ESHD, with moderate long-term toxicities. In almost 10% of patients RT changed partial into complete remission. Should these results be confirmed on a longer follow-up, IFRT will definitely replace STNI in a combined modality treatment

    Purpose: To determine the efficacy and tolerance of a standardized protocol of chemotherapy and low-dose radiotherapy in the treatment of anal cancer in human immunodeficiency virus (HIV)-infected patients. Methods and Materials: Between 1987 and 1995, eight HIV-positive patients with squamous cell carcinoma of the anal canal, four of whom had acquired immunodeficiency syndrome (AIDS), received therapy at the Kaiser Permanente Medical Center. All patients were treated using a combined modality approach consisting of lowdose radiotherapy (30 Gy in 15 fractions delivered 5 days/week), and chemotherapy [1000 mg/m 2 of 5-fluorouracil (5-FU) delivered on days 1-4 and 29-32 as a continuous infusion over 96 h, and 10 mg/m 2 of mitomycin C delivered as a bolus injection on day 1]. Patients have been followed from 4 to 81 months (mean 41, median 38). Results: All eight patients completed the therapy with minor variations to the protocol, and all have attained a clinical complete response. Four patients are alive and free of disease, and four died as a result of complications of AIDS, but remained free of anal carcinoma. There were no mortalities from the protocol and the morbidity was acceptable. Only one patient each was noted to have Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Grade 4 hematologic and gastrointestinal acute toxicity, and no Grade 4 skin toxicity was noted. Conclusion: This combined therapy is effective for HIV-infected patients and appears to be tolerable with acceptable toxicities. It is best applied to patients who are HIV positive, or who have AIDS without concurrent major opportunistic infections. This approach is reasonable and affords patients a reasonably good chance at sphincter preservation by avoiding abdominoperineal resection. The optimal therapy for HIV-positive patients with advanced AIDS remains less well defined

    Breast cancer (BC) is the most frequent cancer and the leading cause of cancer-related mortality in women. The treatment techniques for the BC include chemotherapy (CT) and/or radiotherapy (RT) and can modify elementary the cell matrix by calcificating tissues due to biological and morphological changes. Also, treatments for BC induce cardiotoxicity and it is important to understand the mechanisms involved in order to prevent this late effect in treated breast cancer patients. The high incidence of cardiovascular mortality in breast cancer patients is partially credited to increased intimal and medial calcifications of the aorta. The aim of this work is to investigate the distibution of low atomic number elements such as Magnesium (Mg), due to its importance for the cardiac metabolism; iron (Fe), since BC treatment may be associated with oxidative stress; and Sodium (Na), that is extremely related to the damage of endothelial cells. An optimal technique to observe these changes in aorta tissue is soft X-ray FLuorescence that can provide elemental maps of these important elements. The results performed by Low Energy X-ray Fluorescence LEXRF analyses showed that when the tissue is submitted to treatments with CT and/or RT, some normal structures become disorganized, and consequently the intensity of elemental compounds can be changed. All the experiments were carried out at the TwinMic beamline at Elettra Synchrotron facility using as animal model Wistar rats in order to evaluate the distribution of Na, Mg and Fe in aorta walls of Wistar rats, after BC treatment. Simultaneous acquisition of LEXRF and attenuation coefficient maps suggest that the combined chemotherapy and radiotherapy caused more damage to the aortic tissue as compared to radiation therapy alone. These findings add an in-depth understanding of elemental lack or excess in the tissue and contribute to locate these changes.

    Malignant mesonephric adenocarcinoma of the uterine cervix is a rare occurrence with few cases described in the literature. Although surgery seems to be effective in the treatment of early-stage tumor, no cases describing outcomes of locally advanced stage are available. We report the first case of a patient with International Federation of Obstetrics and Gynecologists stage IIB mesonephric adenocarcinoma undergoing neoadjuvant chemotherapy and radical surgery. Despite the inherent limitation of a single description of a case, our experience supports the utilization of neoadjuvant chemotherapy in patients with malignant mesonephric adenocarcinoma of the uterine cervix. Further prospective multi-institutional studies are needed.

    The aim of this study was to assess the long-term side effects of central nervous system prophylaxis (high-dose chemotherapy alone vs chemotherapy and CNS radiotherapy) according to the ALL IC-BFM 2002. Thirty-tree children aged 6.7-19.9 years have been studied. The control group consisted of 12 children newly diagnosed with acute lymphoblastic leukemia. We assessed subcortical gray matter volume using automatic MRI segmentation and cognitive performance to identify differences between two therapeutic schemes and patients prior to treatment. Patients treated with chemotherapy and CNS radiotherapy had smaller hippocampi than two other subgroups and lower IQ score than patients treated with chemotherapy alone. Both treated groups, whether with chemotherapy only or in combination with CNS radiotherapy, had significantly lower volumes of caudate nucleus and performed significantly worse on measures of verbal fluency in comparison with patients prior to treatment. There were no differences in the mean volumes of total white matter, total gray matter, thalamus, putamen, and amygdala between the studied groups. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment was observed, especially in children who received chemotherapy in combination with reduced dose CNS radiotherapy. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment were observed, especially in children who received chemotherapy in combination with CNS radiotherapy.

    Two male patients who underwent curative surgery and adjuvant radiotherapy (with further chemotherapy in one) for testicular cancer developed adenocarcinoma of the stomach 5 and 19 years after treatment. The stomach is included in the field of radiotherapy used to treat the para-aortic lymph nodes and this may lead to dysplastic changes in the stomach mucosa which can lead to frank malignancy. Early endoscopy should be offered to patients with dyspeptic symptoms after adjuvant radiotherapy for testicular cancer. (author)

    Full Text Available Abstract Background Cancer is one of the major health issues worldwide. An increasing number of cancer patients are offered treatment with surgery, chemotherapy and radiotherapy. Traditional Chinese medicine (TCM is one of the most common complementary therapies offered to cancer patients in Taiwan. We designed a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy of TCM in patients with cancer. Methods/design In this study, inclusion criteria are postoperative patients with histologically confirmed cancer within 3 years who are undergoing chemotherapy or radiotherapy, more than 18 years old, have given signed informed consent, have the ability to read Chinese, and the ability for oral intake. Exclusion criteria include being pregnant, breast feeding, having completed chemotherapy or radiotherapy, brain metastasis with Eastern Cooperative Oncology Group (ECOG performance status of two to four, delusion or hallucinations, acute infection, and have received medications under other clinical trials. The patients were separated into an intervention group (Shen-Mai-San, SMS and a placebo group for four weeks using a randomized, double-blind procedure. The European Organization for Research and Treatment of Cancer (EORTC Quality of Life questionnaire (QOL-C30 was used to evaluate the quality of life. General data, hemoglobin (Hb, hematocrit (Hct, glutamic-oxalacetic transaminase (GOT, glutamic-pyruvic transaminase (GPT, blood urea nitrogen (BUN, creatinine, carcinoembryonic antigen (CEA, TCM diagnosis data and heart rate variability (HRV were also recorded. These data were collected at baseline, two weeks and four weeks after receiving medication. The patients were prescribed granules which contained therapeutic medicines or placebo.

    The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades due to newly found associations with human papillomavirus (HPV) infection. Primary radiotherapy (RT) is the treatment of choice for OPSCC at most centers, and over the last decade, the addition of concurrent chemotherapy has led to a significant improvement in survival, but at the cost of increased acute and late toxicity. Transoral robotic surgery (TORS) has emerged as a promising alternative treatment, with preliminary case series demonstrating encouraging oncologic, functional, and quality of life (QOL) outcomes. However, comparisons of TORS and RT in a non-randomized fashion are susceptible to bias. The goal of this randomized phase II study is to compare QOL, functional outcomes, toxicity profiles, and survival following primary RT (± chemotherapy) vs. TORS (± adjuvant [chemo] RT) in patients with OPSCC. The target patient population comprises OPSCC patients who would be unlikely to require chemotherapy post-resection: Tumor stage T1-T2 with likely negative margins at surgery; Nodal stage N0-2, ≤3 cm in size, with no evidence of extranodal extension on imaging. Participants will be randomized in a 1:1 ratio between Arm 1 (RT ± chemotherapy) and Arm 2 (TORS ± adjuvant [chemo] RT). In Arm 1, patients with N0 disease will receive RT alone, whereas N1-2 patients will receive concurrent chemoradiation. In Arm 2, patients will undergo TORS along with selective neck dissections, which may be staged. Pathologic high-risk features will be used to determine the requirement for adjuvant radiotherapy +/- chemotherapy. The primary endpoint is QOL score using the M.D. Anderson Dysphagia Inventory (MDADI), with secondary endpoints including survival, toxicity, other QOL outcomes, and swallowing function. A sample of 68 patients is required. This study, if successful, will provide a much-needed randomized comparison of the conventional strategy of primary RT

    Between surgery and radiotherapy patients with a malignant glioma may encounter a number of psychosocial issues that could invoke an anxious or depressive response. This study explored the frequency, severity and cause of anxiety and depression in patients with presumed malignant brain tumours in the period between their surgery and radiotherapy. A prospective study of 51 patients used mixed methods to measure anxiety and depression at three time points; post surgery, three weeks post surgery and pre radiotherapy. Analysis was undertaken using statistical and content analysis of the Hospital Anxiety and Depression (HAD) scores and unstructured interviews respectively. Analysis of HAD scores indicated a heightened level of anxiety in patients pre radiotherapy. This anxiety is more prevalent in younger patients and is not related to the patients change in functional state. Five patients had a significant depression at one or more time points between surgery and radiotherapy. Four of the five patients who reported scores consistent with depression had past histories of depression. Content analysis of unstructured interviews indicated that the HAD scores underestimated the presence of anxiety and depression amongst this group of patients. Anxiety was more common in younger patients. Anxiety was slightly more frequent pre-radiotherapy. A past medical history of depression is a predictor of significant depression in the post-operative period. The HAD scale although useful is not an adequate measurement tool for detecting anxiety and depression amongst all patients and health care professionals should adopt other means to monitor for these signs and symptoms.

    To compare results of radiochemotherapy and radiotherapy in patients with cervical cancer. Fifty three patients with locally advanced cervical cancer, undergoing combined radiochemotherapy (C) and a control group of 50 patients treated with irradiation only (R) entered the study. All patients in group C treated with concurrent radiochemotherapy showed positive therapeutic effect - no cases of stable disease nor progress. Complete remission (CR) was observed in more than half of the cases (54.72 %) directly after treatment, as compared with group R - 19.64%. However, more than 70% of patients treated with combined therapy demonstrated bone-marrow damages. Only 4 of these patients (7.55%) did not complete cytostatic treatment because of thrombocytopoenia. Low thrombocyte count caused permanent exclusion of the patient from the chemotherapy schedule. Post-irradiation side effects, such as proctitis, urocystis and enterocolitis posed another problem: combined radiochemotherapy increased the percentage of patients with post-irradiation reactions, although the intensity of these reactions was neither increased nor lenghtier. Our results of combining irradiation with cisplatin-based chemotherapy treatment allow to recommend this schedule of therapy as a standard for locally advanced cervical cancer treatment. (author)

    Objective: To evaluate the safety of cetuximab combined with intensity-modulated radiotherapy (IMRT) plus concurrent cisplatin chemotherapy in locoregionally advanced nasopharyngeal carcinoma (NPC) in a Chinese multicenter clinical study. Methods: From July 2008 to April 2009, 100 Patients with primary stage III- IV b non-keratinizing NPC were enrolled. The planned dose of IMRT to gross tumor volume and positive cervical lymph nodes was 66.0-75.9 Gy and 60-70 Gy in 30-33 fractions. Cisplatin (80 mg/m 2 , q3 week (w)) and cetuximab (400 mg/m 2 one w before radiation, and then 250 mg/m 2 per w) were given concurrently. The adverse events (AEs) were graded according to common terminology criteria for adverse events v3.0. Results: The compliance of the entire group of patient was satisfactory. Actual median dose to gross tumor volume was 69.96 Gy, and the median dose to positive cervical lymph nodes was 68 Gy. Median dose of cisplatin was 133 mg, median first-dose of cetuximab was 690 mg, and median weekly dose was 410 mg. AEs were well tolerated and manageable, mainly consisting of acneiform skin eruptions,dermatitis and mucositis. Grade 4 mucositis was observed in 2% of the patients and no other grade 4 AEs were observed. Conclusions: The combined treatment modality of IMRT + concurrent chemotherapy + cetuximab in loco-regionally advanced NPC is well tolerated. (authors)

    Even though more than 90% of adolescents with low-risk classical Hodgkin lymphoma (LRcHL) will be cured with first-line therapy, many will suffer serious late toxic effects from radiotherapy (RT). The goals for care have shifted toward minimizing late toxic effects without compromising the outstanding cure rates by adapting a risk and response-based therapy. Recent published and ongoing randomized clinical trials, using functional imaging, may allow for better identification of those patients for whom RT may be safely omitted while maintaining excellent cure rates. To evaluate the best chemotherapy regimens with a reasonable toxicity profile and that are expected to have a high chance of omitting RT based on a response-directed therapy while maintaining high cure rates, a mini review was conducted of the recent clinical trials in pediatric and adult LRcHL. The UK RAPID trial chemotherapy backbone (3 × ABVD) followed by a response-based positron emission tomography scan offers up to a 75% chance of safely omitting RT without compromising the cure rate, which remained well above 90%.

    Treatment outcomes of patients with pelvic recurrence after hysterectomy alone for uterine cervical cancer who received salvage radiotherapy (RT) with or without concurrent chemotherapy were investigated. Salvage RT for recurrent cervical cancer confined to the pelvic cavity after hysterectomy alone was received by 33 patients. The median interval between initial hysterectomy and recurrence was 26 months. Whole-pelvic irradiation was delivered to median dose of 45 Gy, followed by a boost with a median dose of 16 Gy to the gross tumor volume. Cisplatin-based concurrent chemotherapy was administered to 29 patients. The median follow-up period was 53 months for surviving patients. Most patients (97.0%) completed salvage RT of ≥45 Gy. Complete response (CR) was achieved in 23 patients (69.7%). Pelvic sidewall involvement and evaluation with positron-emission tomography-computed tomography were significantly associated with CR. The 5-year progression-free survival (PFS), local control (LC), distant metastasis-free survival (DMFS), and overall survival (OS) rates were 62.7, 79.5, 72.5, and 60.1%, respectively. Initial International Federation of Gynecology and Obstetrics stage, pelvic sidewall involvement, and CR status were significant factors for PFS and OS rates in multivariate analysis. The incidence of severe acute and late toxicities (≥grade 3) was 12.1 and 3.0%, respectively. Aggressive salvage RT with or without concurrent chemotherapy for recurrent cervical cancer confined to the pelvic cavity was feasible, with promising treatment outcomes and acceptable toxicities. However, even more intensive novel treatment strategies should be investigated for patients with unfavorable prognostic factors. (orig.)

    Standard therapy for limited stage small cell lung cancer (L-SCLC) is concurrent chemotherapy and radiotherapy followed by prophylactic cranial radiotherapy. Predictors of post chemoradiotherapy pulmonary toxicity in limited stage (LS) small cell lung cancer (SCLC) patients are not well defined. Current guidelines are derived from non-small cell lung cancer regimens, and do not account for the unique biology of this disease. Therefore, we analyzed patients on three consecutive CALGB LS-SCLC trials treated with concurrent chemotherapy and daily high dose radiotherapy (70 Gy) to determine patient and treatment related factors predicting for post-treatment pulmonary toxicity. Patients treated on CALGB protocols 39808, 30002, 30206 investigating two cycles of chemotherapy followed by concurrent chemotherapy and 70 Gy daily thoracic radiation therapy were pooled. Patient, tumor, and treatment related factors were evaluated to determine predictors of grade 3–5 pulmonary toxicities after concurrent chemoradiotherapy. 100 patients were included. No patient experienced grade 4–5 post-treatment pulmonary toxicity. Patients who experienced post-treatment pulmonary toxicity were more likely to be older (median age 69 vs 60, p = 0.09) and have smaller total lung volumes (2565 cc vs 3530 cc, p = 0.05).). Furthermore,exposure of larger volumes of lung to lower (median V5 = 70%, p = 0.09, median V10 = 63%, p = 0.07), inter-mediate (median V20 = 50, p = 0.04) and high (median V60 = 25%, p = 0.01) doses of radiation were all associated with post-treatment grade 3 pulmonary toxicity, as was a larger mean lung radiation dose(median 31 Gy) p = 0.019. Post-treatment pulmonary toxicity following the completion of 2 cycles of chemotherapy followed by concurrent chemotherapy and high dose daily radiation therapy was uncommon. Care should be taken to minimize mean lung radiation exposure, as well as volumes of low, intermediate and high doses of radiation.

    Despite a large number of clinical trials having been conducted to assess the efficacy of adjuvant chemotherapy after surgery for various cancers, whether it is best to use this treatment remains a generally contentious issue for many common cancers. The purpose of this study was to ascertain whether any general conclusions can be drawn about the efficacy or inefficacy of this treatment within different cancer classifications. Meta-analyses of randomized, controlled trials (RCTs) of adjuvant chemotherapy after surgery were synthesized over as many types of cancer as possible. Data sources were Medline, Embase, and the Cochrane library. Eligible meta-analyses were meta-analyses of RCTs for any type of cancer that compared surgery followed by adjuvant chemotherapy with surgery followed by no adjuvant chemotherapy. The literature search found 25 meta-analyses for 15 cancer types that satisfied the criteria necessary for detailed analysis within this study. The estimates of relative risk for all cause mortality were reported as being less than one (indicating adjuvant chemotherapy is beneficial) by all meta-analyses apart from a meta-analysis for colorectal cancer metastasized to the liver. Moreover, 15 of these meta-analyses also reported that the 95% confidence interval for this relative risk is less than one (indicating statistical significance at the 5% level). The results for all cancer types included in this study except for cancer metastasized to the liver can be thought of as supporting each other through the idea of there being a common treatment effect or at least a common range of effect across all (or most) of these cancer types. For example, with regard to cancer types where the evidence in favor of adjuvant chemotherapy after surgery is only moderately strong, the results of this study may encourage more clinicians to regard the use of this treatment as standard practice.

    Full Text Available Abstract Background The objective of this retrospective study is to investigate laryngeal preservation and long-term treatment results in hypopharyngeal carcinoma treated with intensity-modulated radiotherapy (IMRT combined with chemotherapy. Methods Twenty-seven patients with hypopharyngeal carcinoma (stage II-IV were enrolled and underwent concurrent chemoradiotherapy. The chemotherapy regimens were monthly cisplatin and 5-fluorouracil for six patients and weekly cisplatin for 19 patients. All patients were treated with IMRT with simultaneous integrated boost technique. Acute and late toxicities were recorded based on CTCAE 3.0 (Common Terminology Criteria for Adverse Events. Results The median follow-up time for survivors was 53.0 months (range 36-82 months. The initial complete response rate was 85.2%, with a laryngeal preservation rate of 63.0%. The 5-year functional laryngeal, local-regional control, disease-free and overall survival rates were 59.7%, 63.3%, 51.0% and 34.8%, respectively. The most common greater than or equal to grade 3 acute and late effects were dysphagia (63.0%, 17 of 27 patients and laryngeal stricture (18.5%, 5 of 27 patients, respectively. Patients belonging to the high risk group showed significantly higher risk of tracheostomy compared to the low risk group (p = 0.014. Conclusions After long-term follow-up, our results confirmed that patients with hypopharyngeal carcinoma treated with IMRT concurrent with platinum-based chemotherapy attain high functional laryngeal and local-regional control survival rates. However, the late effect of laryngeal stricture remains a problem, particularly for high risk group patients.

    Many efforts have been made to detect local relapse (LR) in the follow-up after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC) although limited data are available on its treatment and prognosis. We aimed to characterize treatment options and clarify long-term outcomes of isolated LR after SBRT for patients with clinical stage I NSCLC. We reviewed our institutional database in search of patients with isolated LR after SBRT for clinical stage I NSCLC at our institution between 1999 and 2013. Patient characteristics were compared with Mann-Whitney U test, χ2 test, or Fisher's exact test as appropriate. Survival outcomes were estimated with Kaplan-Meier method. Potential prognostic factors were investigated using Cox proportional hazard model. Of 308 patients undergoing SBRT for clinical stage I NSCLC, 49 patients were identified to have isolated LR. Twelve patients underwent salvage surgery, none underwent radiotherapy, and eight patients received chemotherapy, whereas 29 patients received best supportive care. No patient characteristic except operability was significantly related with patient selection for LR treatments. Five-year overall survival (OS) rate of the whole cohort was 47.9% from SBRT and 25.7% from LR. Salvage surgery was associated with improved OS after LR (p = 0.014), and 5-year OS for patients undergoing salvage surgery was 79.5% from LR. It was confirmed that our patient selection for salvage surgery for isolated LR was associated with favorable survival outcomes. Operability based on multidisciplinary conferences, rather than measurable patient characteristics, is essential for appropriate patient selection for salvage surgery.

    Full Text Available Abstract Purpose To report the treatment results and prognostic factors of childhood patients with Hodgkin's disease treated with chemotherapy (CT followed by low dose radiotherapy (RT. Patients and methods This retrospective series analyzed 166 patients under 18 years old, treated from January 1985 to December 2003. Median age was 10 years (range 2–18. The male to female ratio was 2,3 : 1. Lymphonode enlargement was the most frequent clinical manifestation (68%, and the time of symptom duration was less than 6 months in 55% of the patients. In histological analysis Nodular Sclerosis was the most prevalent type (48% followed by Mixed Celularity (34.6%. The staging group according Ann Arbor classification was: I (11.7%, II (36.4%, III (32.1% and IV (19.8%. The standard treatment consisted of chemotherapy multiple drug combination according the period of treatment protocols vigent: ABVD in 39% (n-65 of the cases, by VEEP in 13 %(n-22, MOPP in 13 %(n-22, OPPA-13 %(n-22 and ABVD/OPPA in 22 %(n-33.

    To report the treatment results and prognostic factors of childhood patients with Hodgkin's disease treated with chemotherapy (CT) followed by low dose radiotherapy (RT). This retrospective series analyzed 166 patients under 18 years old, treated from January 1985 to December 2003. Median age was 10 years (range 2–18). The male to female ratio was 2,3 : 1. Lymphonode enlargement was the most frequent clinical manifestation (68%), and the time of symptom duration was less than 6 months in 55% of the patients. In histological analysis Nodular Sclerosis was the most prevalent type (48%) followed by Mixed Celularity (34.6%). The staging group according Ann Arbor classification was: I (11.7%), II (36.4%), III (32.1%) and IV (19.8%). The standard treatment consisted of chemotherapy multiple drug combination according the period of treatment protocols vigent: ABVD in 39% (n-65) of the cases, by VEEP in 13 %(n-22), MOPP in 13 %(n-22), OPPA-13 %(n-22) and ABVD/OPPA in 22 %(n-33). Radiotherapy was device to all areas of initial presentation of disease. Dose less or equal than 21 Gy was used in 90.2% of patients with most part of them (90%) by involved field (IFRT) or mantle field. The OS and EFS in 10 years were 89% and 87%. Survival according to clinical stage as 94.7%, 91.3%, 82.3% and 71% for stages I to IV(p = 0,005). The OS was in 91.3% of patients who received RT and in 72.6% of patients who did not (p = 0,003).

    Purpose: This study explored the relationship between radiation dose and reduction in local recurrence rate after preoperative and postoperative radiotherapy in rectal cancer. Methods and Materials: All randomized trials initiated prior to 1988 comparing preoperative and postoperative radiotherapy with surgery alone or with each other were included. Local failure rates were available in 5626 randomized patients. The linear quadratic formula was used to compensate for different radiotherapy schedules. Results: For preoperative radiotherapy, a clear dose-response relationship could be established. For postoperative radiotherapy, the range of doses was narrow, and a dose-response relationship could not be demonstrated. At similar doses, preoperative radiotherapy appeared to be more efficient in reducing local failure rate than postoperative. The only trial comparing preoperative with postoperative radiotherapy confirms this notion. A 15-20 Gy higher dose may be required postoperatively than preoperatively to reach similar efficacy. Neither approach alone significantly influences survival, although it is likely that a small survival benefit may be seen after preoperative radiotherapy. Conclusions: The information from the entire randomized experience suggests that preoperative radiotherapy may be more dose efficient than postoperative radiotherapy

    To present our experience of intensity-modulated radiotherapy (IMRT) with simultaneous modulated accelerated radiotherapy (SMART) boost technique in patients with nasopharyngeal carcinoma (NPC). Sixty eight patients of NPC were treated between April 2006 and December 2011 including 45 males and 23 females with mean age of 46 (range 15–78). Stage distribution was; stage I 3, stage II 7, stage III 26 and stage IV 32. Among 45 (66.2%) evaluated patients for presence of Epstein-Barr virus (EBV), 40 (88.8%) were positive for EBV. Median radiation doses delivered to gross tumor volume (GTV) and positive neck nodes were 66–70 Gy, 63 Gy to clinical target volume (CTV) and 50.4 Gy to clinically negative neck. In addition 56 (82.4%) patients with bulky tumors (T4/N2+) received neoadjuvant chemotherapy 2–3 cycles (Cisplatin/Docetaxel or Cisplatin/Epirubicin or Cisplatin/5 Flourouracil). Concurrent chemotherapy with radiation was weekly Cisplatin 40 mg/m 2 (40 patients) or Cisplatin 100 mg/m 2 (28 patients). With a median follow up of 20 months (range 3–43), one patient developed local recurrence, two experienced regional recurrences and distant failure was seen in 3 patients. Estimated 3 year disease free survival (DFS) was 94%. Three year DFS for patients with EBV was 100% as compared to 60% without EBV (p = 0.0009). Three year DFS for patients with undifferentiated histology was 98% as compared to 82% with other histologies (p = 0.02). Acute grade 3 toxicity was seen as 21 (30.9%) having G-III mucositis and 6 (8.8%) with G-III skin reactions. Late toxicity was minimal and loss of taste was seen in 3 patients (7.5%) at time of analysis. IMRT with SMART in combination with chemotherapy is feasible and effective in terms of both the clinical response and safety profile. EBV, histopathology and nodal involvement were found important prognostic factors for locoregional recurrence

    Neoadjuvant chemotherapy (NAC) and chemoradiotherapy have been shown to extend postoperative survival, and preoperative therapy followed by esophagectomy has become the standard treatment worldwide for patients with esophageal squamous cell carcinoma (ESCC). The Japan Clinical Oncology Group 9907 study showed that NAC significantly extended survival in advanced ESCC, but the survival benefit for patients with clinical stage III disease remains to be elucidated. We compared the survival rates of NAC and upfront surgery in patients with clinical stage III ESCC. Consecutive patients histologically diagnosed as clinical stage III (excluding cT4) ESCC were eligible for this retrospective study. Between September 2002 and April 2007, upfront transthoracic esophagectomy was performed initially and, for patients with positive lymph node (LN) metastasis in a resected specimen, adjuvant chemotherapy using cisplatin and 5-fluororouracil every 3 weeks for two cycles was administered (Upfront surgery group). Since May 2007, a NAC regimen used as adjuvant chemotherapy followed by transthoracic esophagectomy has been administered as the standard treatment in our institution (NAC group). Patient characteristics, clinicopathological factors, treatment outcomes, post-treatment recurrence, and overall survival (OS) were compared between the NAC and upfront surgery groups. Fifty-one and 55 patients were included in the NAC and upfront surgery groups, respectively. The R0 resection rate was significantly lower in the NAC group than in the upfront surgery group (upfront surgery, 98%; NAC, 76%; P = 0.003). In the upfront surgery group, of 49 patients who underwent R0 resection and pathologically positive for LN metastasis, 22 (45%) received adjuvant chemotherapy. In the NAC group, 49 (96%) of 51 patients completed two cycles of NAC. In survival analysis, no significant difference in OS was observed between the NAC and upfront surgery groups (NAC: 5-year OS, 43.8%; upfront surgery: 5

    Purpose: To investigate the potential for mathematic modeling in the assessment of symptom relief in palliative radiotherapy and cytotoxic chemotherapy. Methods: The linear quadratic model of radiation effect with the overall treatment time and the daily dose equivalent of repopulation is modified to include the regrowth time after completion of therapy. Results: The predicted times to restore the original tumor volumes after treatment are dependent on the biological effective dose (BED) delivered and the repopulation parameter (K); it is also possible to estimate K values from analysis of palliative treatment response durations. Hypofractionated radiotherapy given at a low total dose may produce long symptom relief in slow-growing tumors because of their low α/β ratios (which confer high fraction sensitivity) and their slow regrowth rates. Cancers that have high α/β ratios (which confer low fraction sensitivity), and that are expected to repopulate rapidly during therapy, are predicted to have short durations of symptom control. The BED concept can be used to estimate the equivalent dose of radiotherapy that will achieve the same duration of symptom relief as palliative chemotherapy. Conclusion: Relatively simple radiobiologic modeling can be used to guide decision-making regarding the choice of the most appropriate palliative schedules and has important implications in the design of radiotherapy or chemotherapy clinical trials. The methods described provide a rationalization for treatment selection in a wide variety of tumors

    Objective: Many patients with a diagnosis of pancreatic cancer are not offered any therapeutic intervention other than surgical bypass due to very poor prognosis, poor patient tolerance to current therapeutic regimens, and a dismal tumor response to therapy. In view of these circumstances, an acceptable treatment regimen for pancreatic cancer must first demonstrate an ability to obtain a rapid tumor response with a regimen that will be well tolerated enabling the patient to maintain a good quality of life with full ambulatory status. Materials and Methods: Nine unresectable pancreatic cancer patients ((4(9)) had liver metastases) with an average age of 62 (range: 41-79) were treated with a concurrent regimen consisting of 5-Fluorouracil (CI 200-250 mg/m 2 /24 hrs) and Cisplatin (CI 5mg/24 hrs: 2 weeks on, 1 week off) given simultaneously with 3-D planned BID hyperfractionated radiotherapy to the pancreas (5940 cGy/66 fractions/6.5 weeks), and whole liver (1980 cGy/22 fractions/2 weeks), plus additional dose to the partial liver in metastatic disease. Continuous infusion combination chemotherapy was continued alone after radiotherapy for a total of six months. Chemotherapy was delivered by dual light weight portable external pumps. Hyperalimentation was used as needed to maintain nutritional status and warfarin thromboembolic prophylaxis was also utilized. Tumor response was monitored by monthly abdominal CAT scans, serum markers (CEA, CA 19-9), weight gain, and symptomatology. Full radiographic resolution of tumor mass was considered to be a complete response (CR), whereas 50% or greater radiographic decrease in size was considered a partial response (PR). Evaluation was done by independent diagnostic radiologists. Results: CR and PR of the pancreatic mass was achieved in 88% of all patients ((8(9))). CR was achieved in 44% of all patients ((4(9))). Patients with liver metastases exhibited 75% ((3(4))) PR in liver masses and either CR or PR in the primary site. All

    Purpose: To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery. Methods and Materials: The records of 17 primary sacral chordoma patients treated since 1990 with surgery (n = 10) or carbon ion RT (n = 7) were retrospectively analyzed for disease-specific survival, local recurrence-free survival, complications, and functional outcome. The applied carbon ion dose ranged from 54.0 Gray equivalent (GyE) to 73.6 GyE (median 70.4). Results: The mean age at treatment was 55 years for the surgery group and 65 years for the carbon ion RT group. The median duration of follow-up was 76 months for the surgery group and 49 months for the carbon ion RT group. The local recurrence-free survival rate at 5 years was 62.5% for the surgery and 100% for the carbon ion RT group, and the disease-specific survival rate at 5 years was 85.7% and 53.3%, respectively. Urinary-anorectal function worsened in 6 patients (60%) in the surgery group, but it was unchanged in all the patients who had undergone carbon ion RT. Postoperative wound complications requiring reoperation occurred in 3 patients (30%) after surgery and in 1 patient (14%) after carbon ion RT. The functional outcome evaluated using the Musculoskeletal Tumor Society scoring system revealed 55% in the surgery group and 75% in the carbon ion RT group. Of the six factors in this scoring system, the carbon ion RT group had significantly greater scores in emotional acceptance than did the surgery group. Conclusion: Carbon ion RT results in a high local control rate and preservation of urinary-anorectal function compared with surgery.

    Dermato-fibrosarcoma protuberans is a low incidence skin neoplasia of difficult management due to its high recurrence rate. Usual treatment consists of a large resection, some times causing functional and aesthetics impairment, and despite these efforts, published data point to a recurrence rate of 11% to 53%. Recently, radiotherapy has been used modifying the unreal course of this tumor, decreasing drastically the recurrence rate when compared to surgery only. We reviewed these treatment modalities and related three cases of large recurrent tumors treated in our plastic surgery department with surgery and adjuvant radiotherapy, without recurrences after 2 years follow up.

    Purpose: To analyze the long-term results of a Phase II trial of radiotherapy given immediately after hyperbaric oxygenation (HBO) with multiagent chemotherapy in adults with high-grade gliomas. Methods and Materials: Patients with histologically confirmed high-grade gliomas were administered radiotherapy in daily 2 Gy fractions for 5 consecutive days per week up to a total dose of 60 Gy. Each fraction was administered immediately after HBO, with the time interval from completion of decompression to start of irradiation being less than 15 minutes. Chemotherapy consisting of procarbazine, nimustine, and vincristine and was administered during and after radiotherapy. Results: A total of 57 patients (39 patients with glioblastoma and 18 patients with Grade 3 gliomas) were enrolled from 2000 to 2006, and the median follow-up of 12 surviving patients was 62.0 months (range, 43.2-119.1 months). All 57 patients were able to complete a total radiotherapy dose of 60 Gy immediately after HBO with one course of concurrent chemotherapy. The median overall survival times in all 57 patients, 39 patients with glioblastoma and 18 patients with Grade 3 gliomas, were 20.2 months, 17.2 months, and 113.4 months, respectively. On multivariate analysis, histologic grade alone was a significant prognostic factor for overall survival (p < 0.001). During treatments, no patients had neutropenic fever or intracranial hemorrhage, and no serious nonhematologic or late toxicities were seen in any of the 57 patients. Conclusions: Radiotherapy delivered immediately after HBO with multiagent chemotherapy was safe, with virtually no late toxicities, and seemed to be effective in patients with high-grade gliomas.

    Locoregional spread of abdominopelvic malignant tumors frequently results in peritoneal carcinomatosis (PC). The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases I, II and III clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.

    Purpose: The role of neck surgery in node- positive patients whose primary tumours are treated by definitive radiotherapy is controversial. A planned neck dissection following radiotherapy is frequently recommended regardless of response of the neck nodes to treatment. This analysis was undertaken to assess the risk of withholding planned neck dissection in patients who obtain a complete nodal response to irradiation. Materials and Methods: The analysis is based on all 100 patients treated using the concomitant boost protocol described below who presented between 1984 and 1993 with primary squamous cell carcinomas of the oropharynx and clinically positive cervical lymphadenopathy. There were 73 males and 27 females with a median age of 59. Primary disease site was base of tongue 39, tonsil 40, soft palate 14 and pharyngeal wall 7. Nodal stages were N1: 35, N2: 51 and N3: 15. Nodal size varied from 1 - 9 cm with a median of 3 cm. Radiotherapy consisted of 54 Gy in 30 fractions over 6 weeks to large fields with a boost to gross disease of 18 Gy in 12 fractions being delivered as a second daily fraction during the last 2.4 weeks of treatment. Seventy-five patients had their nodal disease treated definitively by radiotherapy; those who had complete clinical resolution of all nodal disease (62) had no planned surgery, while the remaining 13 underwent neck dissection for presumed residual disease. Twenty-five patients had either node excision (8) or neck dissection (17) prior to radiotherapy. Results: There were 8 cases of isolated neck failure of which 3 occurred in the 62 patients who had no planned neck surgery, 0 in the 13 patients who were operated for presumed residual disease (pathologically negative in 7) and 5 in the 25 patients who had initial neck surgery. Of the 62 patients who had a complete response to radiotherapy, the two year probability of neck control was 87% if the initial nodal size was ≤ 3 cm versus 85% for nodes > 3 cm. However the likelihood of

    Purpose: To investigate the importance of preirradiation mental and endocrinological evaluation, and the effectiveness of involved-field radiotherapy following neoadjuvant chemotherapy. Methods and Materials: Following etoposide and cisplatin with or without ifosfamide, 13 patients with nondisseminated disease received involved-field irradiation of 24 Gy in 12 fractions within 3 weeks and 2 patients with disseminated germinoma received 24 Gy craniospinal irradiation (CSI). CT simulation was used to cover the tumor bed. Results: Full-scale intelligence quotient (IQ) tests given at the time of the initial radiotherapy showed less than 90 in 7 of 11 patients who had tumors involving the neurohypophyseal region, but the 4 patients who had solitary pineal tumors showed higher scores. Panhypopituitarism was observed in 9 patients with tumors involving the neurohypophyseal region. All patients are alive without disease, with a median follow-up period of 40 months. No in-field relapse was noted after the involved-field radiotherapy. One patient experienced a recurrence outside of the planning target volume. Conclusion: Decline of neurocognitive and endocrine functions were often seen in patients with tumors involving the hypophyseal region, but not in patients with solitary pineal germinoma before radiotherapy. Involved-field radiotherapy using 24 Gy is effective with the help of CT simulation and neoadjuvant chemotherapy

    Full Text Available Background and Aims: Cytoreductive surgery (CRS combined with hyperthermic intraperitoneal chemotherapy (HIPEC is becoming the standard treatment option for peritoneal carcinomatosis but is associated with high rates of morbidity and mortality. Our aim was to retrospectively analyse and evaluate intra-operative factors associated with morbidity and mortality of CRS and HIPEC. Methods: Intra-operative data were collected for cases done over 1 year (24 cases and analysed for the primary outcome of post-operative ventilation >24 h, and secondary outcome of length of the Intensive Care Unit (ICU stay >5 days. Statistical analysis was carried out in STATA 11 software. Results: Higher peritoneal carcinoma index (PCI, (P = 0.0047, longer duration of surgery (P = 0.0016, higher delta temperatures (P = 0.0119, increased estimated blood loss (EBL (P = 0.0054, high intraoperative fluid requirement (P = 0.0038, lower mean arterial pressure (MAP (P = 0.0021 and higher blood products requirement were associated with >24 h ventilation. These factors were also associated with longer ICU stay. All these factors associated with >24 h ventilation and prolonged ICU stay are related to the PCI which is an indicator of the extent of surgery. Conclusion: Higher PCI, longer duration of surgery, higher delta temperatures, increased EBL, high intraoperative fluid requirement, lower mean arterial pressure and higher blood products requirement were associated with >24 h postoperative ventilation as well as ICU stay >5 days. All these factors are related to the PCI, which is a major predictor of post-operative morbidity.

    Purpose: to determine the maximum tolerated dose (MTD) of gemcitabine every 2 weeks to a concurrent radiotherapy administered during an aggressive program of sequential and simultaneous radio-/chemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC). Patients and methods: ten patients with histologically confirmed NSCLC were observed and treated in accordance with a combined radio-/chemotherapy protocol. This included two cycles of induction chemotherapy with gemcitabine (1,200 mg/m{sup 2}) and vinorelbine (30 mg/m{sup 2}) at days 1, 8 and 22, 29, followed by concurrent radiotherapy including [{sup 18}F] fluorodeoxyglucose positron emission tomography-(FDG-PET-) based target volume definition (2.0 Gy/d; total dose 66.0 Gy) and chemotherapy with gemcitabine every 2 weeks at days 43, 57, and 71. The initial dose was 300 mg/m{sup 2}. The dose of gemcitabine was increased by 100 mg/m{sup 2} until the MTD was realized. Three patients were enrolled for each dose level. Results: dose-limiting toxicity (DLT) was identified for the patient group receiving gemcitabine 500 mg/m{sup 2}, due to grade 2 esophagitis (next to grade 3) in all patients. 6 weeks after the completion of radio-/chemotherapy, most patients still presented treatment-induced esophagitis. In accordance with expected complications, such as esophagitis, dysphagia and odynophagia, the MTD was defined at this dose level, although no DLT grade 3 was reached. Conclusion: after induction chemotherapy, the MTD and frequency of gemcitabine in locally advanced NSCLC is 500 mg/m{sup 2} every 2 weeks during a maximum of 7 weeks of thoracic radiotherapy.

    Full Text Available Abstract Background 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. 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.

    Over the past four years, 27 patients with recurrent tumors of the head and neck region have been treated with chemotherapy. The regimens used were BCMF (bleomycin 15 mg i.v. for 3 days, cyclophosphamide 500 mg i.v., methotrexate 50 mg i.v. and 5-fluorouracil 500 mg i.v.) and CMU (cyclophosphamide 350 mg/m 2 i.v., methotrexate 30 mg/m 2 i.v. and UFT 600 mg p.o. for 14 days). Of the 27 patients, eight were treated with combined radiation and chemotherapy, and either CR or PR was obtained. Nineteen patients were treated with chemotherapy alone, for which the response (CR + PR) rates were 8 % (1/12) for BCMF and 43 % (3/7) for CMU, respectively. No serious toxicities were observed as a result of these regimens. It was thus demonstrated that the CMU regimen was of great value in terms of improved response and minor toxicity in the treatment of head and neck tumors. (author)

    Purpose: We have previously shown that delivering targeted radiotherapy to the tumour bed intraoperatively is feasible and desirable. In this study, we report on the feasibility, safety, and long-term efficacy of TARGeted Intraoperative radioTherapy (Targit), using the Intrabeam system. Methods and Materials: A total of 300 cancers in 299 unselected patients underwent breast-conserving surgery and Targit as a boost to the tumor bed. After lumpectomy, a single dose of 20 Gy was delivered intraoperatively. Postoperative external beam whole-breast radiotherapy excluded the usual boost. We also performed a novel individualized case control (ICC) analysis that computed the expected recurrences for the cohort by estimating the risk of recurrence for each patient using their characteristics and follow-up period. Results: The treatment was well tolerated. The median follow up was 60.5 months (range, 10-122 months). Eight patients have had ipsilateral recurrence: 5-year Kaplan Meier estimate for ipsilateral recurrence is 1.73% (SE 0.77), which compares well with that seen in the boosted patients in the European Organization for Research and Treatment of Cancer study (4.3%) and the UK STAndardisation of breast RadioTherapy study (2.8%). In a novel ICC analysis of 242 of the patients, we estimated that there should be 11.4 recurrences; in this group, only 6 recurrences were observed. Conclusions: Lumpectomy and Targit boost combined with external beam radiotherapy results in a low local recurrence rate in a standard risk patient population. Accurate localization and the immediacy of the treatment that has a favorable effect on tumour microenvironment may contribute to this effect. These long-term data establish the long-term safety and efficacy of the Targit technique and generate the hypothesis that Targit boost might be superior to an external beam boost in its efficacy and justifies a randomized trial.

    Purpose: To evaluate the role of radiotherapy (RT) and prognostic factors in 62 patients with brain metastases from transitional cell carcinoma (TCC) of the urinary bladder. Patients and Methods: 62 patients received either RT (n = 49), including whole-brain radiotherapy (WBRT) and/or stereotactic radiosurgery (SRS), or surgery (OP) combined with WBRT (n = 13). Overall survival (OS), intracerebral control (ICC) and local control (LC) were retrospectively analyzed. Six potential prognostic factors were assessed: age, gender, number of brain metastases, extracerebral metastases, recursive partitioning analysis (RPA) class, and interval from tumor diagnosis to RT. Results: Median OS and ICC for the entire cohort were 9 and 7 months. No significant difference between RT and OP + RT was found for OS (p = 0.696) and ICC (p = 0.996). On multivariate analysis, improved OS was associated with lack of extracerebral metastases (p < 0.001) and RPA class (p < 0.001), and ICC with the latter (p < 0.001). SRS-incorporating RT resulted in 1-, 2-, and 3-year LC probability of 78%, 66%, and 51%. No association between LC and any of the potential prognostic factors was observed. The results of the subgroup RPA class analyses were similar to the entire cohort. Conclusion: Patient outcome for the RT-alone arm was not significantly different from OP + RT. SRS-incorporating treatment offers excellent LC rates. RPA class and the presence of extracerebral metastases demonstrated a significant prognostic role for survival. The latter should be used as stratification factors in randomized trials and can help define the cohort of patients that may benefit from more aggressive therapies. (orig.)

    Children with high-risk medulloblastoma historically have had a poor prognosis. The Children's Oncology Group completed a Phase II study using oral etoposide given with radiotherapy followed by intensive chemotherapy. Patients enrolled in the study had high-risk disease defined as ≥1.5 cm 2 of residual disease postsurgery or definite evidence of central nervous metastasis. All patients underwent surgery followed by radiotherapy. During radiation, the patients received oral etoposide (21 days on, 7 off) at an initial dose of 50 mg/m 2 per day (treatment 1), which was reduced to 35 mg/m 2 per day (treatment 2) due to toxicity. After radiotherapy, the patients received chemotherapy with three cycles of cisplatin and oral etoposide, followed by eight courses of cyclophosphamide and vincristine. Between November 1998 and October 2002, 53 patients were accrued; 15 received treatment 1 and 38 treatment 2. Forty-seven patients (89%) were eligible. Response to radiation was excellent, with 19 (40.4%) showing complete response, 24 (51.1%) partial response, and four (8.5%) no recorded response. The overall 2- and 5-year progression-free survival (PFS) was 76.6 ± 6% and 70.2 ± 7%, respectively. The 2- and 5-year overall survival (OS) was 80.9 ± 6% and 76.6 ± 6%, respectively. Clinical response postradiation and PFS/OS were not significantly different between the treatment groups. There was a trend toward a difference in 5-year PFS between those without and with metastatic disease (P = 0.072). Oral etoposide was tolerable at 35 mg/m 2 (21 days on and 7 days off) when given during full-dose irradiation in patients with high-risk medulloblastoma with encouraging survival data. © 2016 Wiley Periodicals, Inc.

    We analyzed the results and clinical features of 41 patients with T1 or T2 squamous cell carcinoma of the hypopharynx who received the treatment of laser surgery combined with radiotherapy at the Kurume University Hospital between 1989 and 2003. The patients consisted of 38 males and 3 females (mean age: 64 years); T classification was 8 T1 cases and 33 T2 cases. N classification of the patients was 20 N0 cases, 9 N1 cases, 10 N2 cases, and 2 N3 cases. Three were stage I, 17 were stage II, 9 were stage III, and 12 were stage IV. Sub-sites of the tumor were 33 of piriform sinus type, 6 of post-cricoid type and 2 of poterior wall type. The primary disease was treated by laser debulking surgery combined with radiotherapy. Local recurrence was recognized in 4 cases and laryngectomy was performed in 3 cases. As a result, 38 (92.6%) cases were treated by preserving the larynx. All patients could eat a meal from the day following the operation. Tracheostomy was performed in six cases, but the tracheal stoma could be closed in five. The disease-specific 5-year survival rate was 87.7%. The 5-year local control rate was 90.2%. The overall 5-year survival rate was 49.2%. Four patients died of the primary disease (lymph node death: 3, distant metastasis death: 1). This retrospective review indicates that laser debulking surgery combined with radiotherapy is a successful treatment for T1/T2 hypopharyngeal carcinoma. (author)

    We report our experience with the use of intra-arterial chemotherapy and embolization before limb salvage surgery in patients with osteosarcoma of the lower extremity. We evaluated the effect of this procedure on the degree of tumor necrosis and on the amount of blood loss during surgery. We reviewed the medical records of all patients who received intra-arterial chemotherapy and embolization before undergoing limb salvage surgery for osteosarcoma of the lower extremity at our institution between January 2003 and April 2008. Patient demographic, tumor characteristics, treatment details, postembolization complications, and surgical and pathological findings were recorded for each patient. We evaluated the operative time, estimated blood loss (EBL), and volume of blood transfusion during surgery and in the postoperative period in all patients in the study group. The same parameters were recorded for 65 other patients with lower extremity osteosarcoma who underwent limb salvage operation at our institution without undergoing preoperative intervention. The study included 47 patients (25 males and 22 females). Angiography showed that the tumors were hypervascular. Intra-arterial chemotherapy and embolization were performed successfully, resulting in a substantial reduction or complete disappearance of tumor stain in all patients. No major complications were encountered. At the time of surgery, performed 3-7 days after embolization, a fibrous edematous band around the tumor was observed in 43 of the 47 patients, facilitating surgery. The goal of limb salvage was achieved successfully in all cases. Percentage tumor necrosis induced by treatment ranged from 70.2% to 94.2% (average, 82.9%). EBL during surgery, EBL from drains in the postoperative period, total EBL, and transfusion volumes were significantly lower in the 47 study patients compared to the 65 patients who underwent surgery without preoperative treatment with intra-arterial chemotherapy and embolization.

    We investigated the risk factors, incidence, and role of thromboprophylaxis in the development of thrombosis following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We reviewed data of patients with CRS/HIPEC in three hospitals. Overall, 192 patients underwent CRS/HIPEC during 2007-2016. Mechanical (thigh-length pneumatic compression stockings) and pharmacologic thromboprophylaxis (40 mg enoxaparin daily, starting 12 h before surgery until discharge) was provided for all patients; and 116 (60.4%) also received an extended course of enoxaparin for 2-4 weeks after discharge. Twenty-six patients experienced thrombotic complications (13.5%) including portal-splenic-mesenteric venous thrombosis (n = 11, 5.7%), pulmonary embolism (n = 10, 5.2%), and deep vein thrombosis (n = 5, 2.6%); most (n = 21, 80.8%) occurred after hospital discharge. Univariate analysis identified Peritoneal Cancer Index, intraoperative transfusion requirement, operative blood loss, operative time, lengths of hospital, and intensive care unit stay, and lack of administration of anticoagulation at discharge as significantly associated with thrombosis. With multivariate analysis, only the lack of anticoagulation therapy at discharge remained significantly associated with thrombosis (P = 0.0001). Thromboembolic complications are common following CRS/HIPEC. As significantly lower rates of thrombosis were found in patients who received an extended course of anticoagulation, we support its use for at least 2 weeks after discharge. © 2017 Wiley Periodicals, Inc.

    Sperm counts were low (median, 15 X 10(6) per ejaculate) and serum follicle-stimulating hormone (FSH) levels were moderately elevated (median, 31 IU/l) after unilateral orchiectomy and immediately before radiotherapy and chemotherapy in 34 patients with seminomas and 20 patients with nonseminomatous germ cell tumors. The scattered radiation (0.2 to 1.3 Gray [Gy]) reaching the remaining testicle during radiotherapy caused azoospermia in more than two thirds of the patients. A median of 540 days elapsed after the end of treatment before spermatozoa were again found in semen samples, while a median of 1250 days passed before the pretreatment sperm count was reached. One to 5 years after treatment, sperm counts were still low (median, 6 X 10(6) per ejaculate) and serum FSH was elevated (median, 61 IU/l). The adjuvant chemotherapy given to the 20 patients with nonseminomatous tumors did not appear to affect restitution appreciably

    Radiation and chemotherapy can result in further deterioration of the nutritional status of lung cancer patients who frequently are malnourished as a consequence of their underlying malignancy. Nutritional support of these individuals should be based on a complete assessment of each patient's requirements as well as providing such requirements through a safe efficacious eternal hyperalimentaton program. This investigation was designed to study whether clinically significant palliation maybe achieved by nutritional rehabilitation of the cachetic lung cancer patient as an adjuvant to conventional antitumor therapy.

    Lymphoma is a heterogeneous group of diseases with many curable subtypes. Primary treatment cures a significant proportion of, but not all, patients. Patients not achieving a complete remission with primary treatment, or those who relapse later, have a second chance of cure with high-dose chemotherapy and haematopoietic stem cell transplantation. Response assessment is therefore crucial in the management of lymphomas. FDG-PET has an emerging role in assessing response, both at the end of and during treatment. This article will review the current published evidence and offer some suggestions on future directions from a clinician's viewpoint. (orig.)

    Vaginal carcinoma is a rare gynecological malignancy that is usually treated by radiation therapy and/or surgery combined with chemotherapy. Here, we report a case of invasive vaginal carcinoma in a young woman who underwent fertility-sparing treatment involving neoadjuvant chemotherapy and conservative surgery. A 36-year-old non-parous woman had a solid tumor in the vagina. Positron emission tomography/computed tomography showed a tumor in the vagina with high FDG uptake (SUV = 17.33) but no metastatic lesions. The patient was diagnosed with vaginal squamous cell carcinoma, FIGO stage I, T1N0M0. Because she wished to retain her fertility, neoadjuvant chemotherapy consisting of irinotecan hydrochloride and nedaplatin was initiated. After four courses of chemotherapy, partial vaginectomy was carried out and the pathological diagnosis of the residual lesion was VAIN 3. Following two further courses of the same chemotherapy, she obtained complete response, and has shown no evidence of disease for 14 months. © 2014 The Authors.

    Lung cancer study group at Asan Medical Center has conducted the second prospective study to determine the efficacy and feasibility of MVP chemotherapy with concurrent hyperfractionated radiotherapy for patients with stage III unresectable non-small cell lung cancer(NSCLC). All eligible patients with stage III unresectable NSCLC were treated with hyperfractionated radiotherapy( 120 cGy/fx BID, 6480 cGY/54fx) and concurrent 2 cycles of MVP(Motomycin C 6 mg/m 2 , d2 and d29, Vinblastin 6 mg/m 2 , d2 and d29, Cisplatin 6 mg/m 2 , d1 and d28) chemotherapy. Between Aug. 1993 and Nov. 1994, 62 patients entered this study ; 6(10%) had advanced stage IIIa and 56(90%) had IIIb disease including 1 with pleural effusion and 10 with supraclavicular metastases. Among 62 Patients, 48(77%) completed planned therapy. Fourteen patients refused further treatment during chemoradiotherapy. Of 46 patients evaluable for response, 34(74%) showed major response including 10(22%) with complete and 24(52%) with partial responses. Of 48 patients evaluable for toxicity, 13(27%) showed grade IV hematologic toxicity but treatment delay did not exceed 5 days. Two patients died of sepsis during chemoradiotherapy. Server weight(more than 10%) occurred in 9 patients(19%) during treatment. Nine patients(19%) developed radiation pneumonitis. Six of these patients had grad I(mild) pneumonitis with radiographic changes within the treatment fields. Three other patients had grade II pneumonitis, but none of theses patients had continuous symptoms after steroid treatment. Concurrent chemoradiotherapy for patients with advanced NSCLC was well tolerated with acceptable toxicity and achieved higher response rates than the first study, but rather low compliance rate(7%) in this study is worrisome. We need to improve nutritional support during treatment and to use G-CSF to improve leukopenia and if necessary, supportive care will given as in patients. Longer follow-up and larger sample size is needed to

    Introduction. - Curative therapy for patients with small-cell lung cancer (SCLC) is based on multidrug chemotherapy combinations and radiotherapy. After a long time follow-up, the aim of the study was to evaluate the efficacy and toxicity of sequential chemo-radiotherapy and the effect of prophylactic cranial irradiation (PCI). Methods. - From 1995-2005, 96 patients with SCLC (64 limited-disease [LD], 32 extensive-disease [ED]; median age 61 years [range 39-79]) were treated at our department with varying chemotherapy regimens and sequential mediastinal radiotherapy (50 Gy + 10 Gy boost in case of residual disease after chemotherapy). Afterwards, 15 patients with LD, good general condition and at least partial response after local treatment received PCI (30 Gy). Results. - After a median follow-up of 78.6 months, 20 patients remained alive (20.8%, median survival time 18.2 months). The 2-/5-year overall survival rates were 33.8% and 12.6%, the 2-/5-year loco-regional control rates were 30.3% and 24.5%, respectively. Distant metastases occurred in 43 patients (24 cerebral). Cerebral metastasis occurred in 6.7% and 27.2% of the patients with PCI and without PCI respectively. Only tumor stage showed a statistically significant impact on overall survival and loco-regional control in multivariate analysis. Radiotherapy was well tolerated. Grade 3/4 toxicity occurred in seven patients. Prognosis of patients with SCLC remains poor. Administration of PCI in selected patients bears a decrease in the incidence of cerebral metastases. Alternative chemotherapy schemes as well as irradiation schemes and techniques should be the substance of future randomized trials. (authors)

    Complete cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) is increasingly performed on patients with peritoneal carcinomatosis of various origins. Splenectomy often is required in these patients to achieve complete tumor removal. Although splenectomy has been associated with increased morbidity in many major abdominal surgeries, its effect in patients undergoing CRS + HIPEC is unknown. The purpose of this study was to evaluate the impact of splenectomy during CRS + HIPEC on postoperative outcomes. We retrospectively identified 39 patients who underwent CRS + HIPEC with splenectomy during a 3-year study period from a prospective database. We compared them to case controls (CRS + HIPEC without splenectomy) that were matched for the complexity of the procedure. We evaluated the complication rate and outcomes of patients in each group. During the study period, splenectomy was performed in 32 % of patients undergoing CRS + HIPEC procedure. Patients in the splenectomy group experienced more grade 3-4 complications than patients in the control group (59 vs. 35.9 %, p = 0.041) as well as more pulmonary complications (41 vs. 7.7 %, p = 0.0006). Multivariate analysis identified splenectomy as the only predictor of overall major complications (odds ratio = 2.57, 95 % confidence interval = 1.03-6.40). Mortality was similar in both groups. Splenectomy increases major complication rate in patients undergoing CRS + HIPEC and efforts should be made to preserve the spleen during the surgery.

Group I patients were treated by HFX RT with 1.2 Gy twice daily with a total dose of 64.8 Gy in 27 treatment days, while Groups II and III patients were treated by the same HFX RT and concurrent chemotherapy with carboplatin and etoposide (every week in Group II and every other week in Group III). Interfraction intervals of either 4.5-5 h or 5.5-6 h were used for each patient. Results: Patients treated with shorter interfraction intervals (4.5-5 h) had a better prognosis than those treated with longer intervals (5.5-6 h) (median survival: 22 vs. 7 months; 5-year survival rate: 27% vs. 0%, p = 0.00000). This phenomenon was observed in all treatment groups. Patients ≥ 60 years of age, with Stage IIIA disease, or with previous weight loss ≤ 5% were treated more often with the shorter intervals than those 5%, respectively, but in all of these subgroups of patients, the shorter intervals were associated with a better prognosis. Multivariate analysis showed that the interfraction interval was an independent prognostic factor, together with sex, age, performance status, and stage. The shorter intervals were associated with an increased incidence of acute high grade toxicity, but not with an increase in late toxicity. Conclusion: Patients treated with shorter interfraction intervals (4.5-5 h) appeared to have a better survival than those treated with longer intervals (5.5-6 h). Prospective randomized studies are warranted to further investigate the influence of interfraction interval in HFX RT

    Efficacy and the risk of severe late effects have to be well-balanced in treatment of Hodgkin lymphoma (HL). Late adverse effects include secondary malignancies which often have a poor prognosis. To synthesise evidence on the risk of secondary malignancies after current treatment approaches comprising chemotherapy and/or radiotherapy, we performed a meta-analysis based on individual patient data (IPD) from patients treated for newly diagnosed HL. We investigated several questions concerning possible changes in the risk of secondary malignancies when modifying chemotherapy or radiotherapy (omission of radiotherapy, reduction of the radiation field, reduction of the radiation dose, use of fewer chemotherapy cycles, intensification of chemotherapy). We also analysed whether these modifications affect progression-free survival (PFS) and overall survival (OS). We searched MEDLINE and Cochrane CENTRAL trials databases comprehensively in June 2010 for all randomised trials in HL since 1984. Key international trials registries were also searched. The search was updated in March 2015 without collecting further IPD (one further eligible study found) and again in July 2017 (no further eligible studies). We included randomised controlled trials (RCTs) for untreated HL patients which enrolled at least 50 patients per arm, completed recruitment by 2007 and performed a treatment comparison relevant to our objectives. Study groups submitted IPD, including age, sex, stage and the outcomes secondary malignant neoplasm (SMN), OS and PFS as time-to-event data. We meta-analysed these data using Petos method (SMN) and Cox regression with inverse-variance pooling (OS, PFS) for each of the five study questions, and performed subgroup and sensitivity analyses to assess the applicability and robustness of the results. We identified 21 eligible trials and obtained IPD for 16. For four studies no data were supplied despite repeated efforts, while one study was only identified in 2015 and IPD

    With standard treatment of epithelial ovarian cancer (EOC), prognosis is very poor. The aim of this study is to show early and late results in patients who underwent cytoreductive surgery and intraperitoneal chemotherapy. This was a retrospective single centre study. All patients with advanced and recurrent ovarian cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) or modified early postoperative intraperitoneal chemotherapy (EPIC) were included in the study. In the period 1995-2014, 116 patients were treated, 55 with primary EOC and 61 with recurrent EOC. The mean age was 59 years (26-74). Statistically, median survival time was significantly longer in the group with primary advanced cancer of the ovary (41.3 months) compared to relapsed ovarian cancer (27.3 months). Survival for the primary EOC was 65 and 24% at 3 and 5 years, respectively. Survival for recurrent EOC was 33 and 16% at 3 and 5 years, respectively. Mortality was 1/116 (0.8%). Morbidity was 11/116 (9.5%). Peritoneal cancer index (PCI) was ≤20 in 59 (51%) patients and statistically, their average survival was significantly longer than in the group of 57 (49%) patients with PCI >20 (p = 0.014). In advanced or recurrent EOC, a curative therapeutic approach was pursued that combined optimal cytoreductive surgery and intraperitoneal chemotherapy. PCI and timing of the intervention (primary or recurrent) were the strongest independent prognostic factors.

    Anaplastic thyroid carcinoma (ATC) is an aggressive rare tumor. We analyzed our experience for prognosis and the effect of surgery and radiotherapy on patients with ATC. We conducted a retrospective review of all patients (n = 67) with ATC treated at a tertiary care center from 1969 to 1999. Survivor median follow-up was 51 months. Tumor and patient characteristics and therapy were assessed for effect on survival by multivariate analysis. Patients presented with a neck mass (99%), change of voice (51%), dysphagia (33%), and dyspnea (28%). Surgery was performed in 44 of 67 patients, with 12 complete resections. The 6-month and 1- and 3-year survival rates were 92%, 92%, and 83% after complete resection; 53%, 35%, and 0% after debulking; and 22%, 4%, and 0% after no resection, respectively (P 45 Gy improved survival as compared with a lower dose (P = .02). Multivariate analysis showed that age 45 Gy improves outcome.

  7. Treatment of Early Stage Non-Small Cell Lung Cancer: Surgery or Stereotactic Ablative Radiotherapy?

    Full Text Available The management of early-stage Non-small Cell Lung Cancer (NSCLC has improved recently due to advances in surgical and radiation modalities. Minimally-invasive procedures like Video-assisted thoracoscopic surgery (VATS lobectomy decreases the morbidity of surgery, while the numerous methods of staging the mediastinum such as endobronchial and endoscopic ultrasound-guided biopsies are helping to achieve the objectives much more effectively. Stereotactic Ablative Radiotherapy (SABR has become the frontrunner as the standard of care in medically inoperable early stage NSCLC patients, and has also been branded as tolerable and highly effective. Ongoing researches using SABR are continuously validating the optimal dosing and fractionation schemes, while at the same time instituting its role for both inoperable and operable patients.

    Objective: to determine whether low-level laser therapy can prevent salivary hypofunction after radiotherapy and chemotherapy in head and neck cancer patients. Materials and methods: ee evaluated 23 head and neck cancer patients, of whom 13 received laser therapy and 10 received clinical care only. An InGaAlP laser was used intra-orally (at 660 nm and 40 mW) at a mean dose of 10.0 J/cm 2 and extra-orally (at 780 nm and 15 mW) at a mean dose of 3.7 J/cm 2 , three times per week, on alternate days. Stimulated and unstimulated sialometry tests were performed before the first radiotherapy and chemotherapy sessions (NO) and at 30 days after the end of treatment (N30). Results: At N30, the mean salivary flow rates were significantly higher among the laser therapy patients than among the patients who received clinical care only, in the stimulated and unstimulated sialometry tests (p = 0.0131 and p = 0.0143, respectively). Conclusion: low-level laser therapy, administered concomitantly with radiotherapy and chemotherapy, appears to mitigate treatment induced salivary hypofunction in patients with head and neck cancer.

    Purpose: To evaluate the therapeutic results and rate of organ preservation in patients with stage III or IV oral cancer treated with retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy. Materials and methods: One hundred and twelve patients with stage III and IV oral squamous cell carcinoma underwent intra-arterial chemoradiotherapy. Catheterization from the superficial temporal and occipital arteries was performed. Treatment consisted of superselective intra-arterial chemotherapy (docetaxel, total 60 mg/m 2 , cisplatin, total 150 mg/m 2 ) and daily concurrent radiotherapy (total of 60 Gy) for 6 weeks. Results: The median follow-up for all patients was 46.2 months (range, 10–76 months). After intra-arterial chemoradiotherapy, primary site complete response was achieved in 98 (87.5%) of 112 cases. Five-year survival and local control rates were 71.3% and 79.3%, respectively. Grade 3 or 4 toxicities included mucositis in 92.0%, neutropenia in 30.4%, dermatitis in 28.6%, anemia in 26.8%, and thrombocytopenia in 7.1% of patients. Grade 3 toxicities included dysphagia in 72.3%, nausea/vomiting in 21.4%, fever in 8.0%, and renal failure in 0.9% of patients. Conclusion: Retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy for stage III and IV oral cancer provided good overall survival and local control

    Purpose: to evaluate the feasibility and toxicity of three-times-daily radiotherapy (3tdRT), preceded by induction chemotherapy (iCT), in stage IIIA-IIIB non-small cell lung cancer (NSCLC). Patients and methods: iCT consisted of three cycles of cisplatin and gemcitabine. Surgery was considered for stage IIIA patients responsive to iCT; definitive or postoperative 3tdRT was planned. Doses of 54.4 Gy and 64.6 Gy in postoperative and definitive treatments, respectively, were delivered in three daily fractions. Results: from February 1998 to October 2000, 37 patients received 3tdRT as definitive (n = 18) or postoperative treatment (n = 19). Toxicity was limited to RTOG grade 2 (25 patients, 67.6%) and grade 3 (four patients, 10.8%) acute esophagitis; no grade 3 late esophagitis occurred. Late lung toxicity was represented by one grade 3 pneumonitis. No correlation emerged between acute esophageal toxicity and irradiated esophageal volume or disease- and treatment-related factors. A significant correlation was found for stage (IIIA vs. IIIB; p = 0.03) and a trend for the N-class (N2 vs. N3; p = 0.08). Conclusion: in this experience of 3tdRT preceded by iCT, the low toxicity profile confirmed the feasibility of this combination. The limited statistical power does not permit a definition of predictors for radiation-induced esophagitis incidence and severity; additional studies are required to clarify the impact of volumetric and dosimetric parameters. Failure patterns and survival results are warranted to confirm the efficacy of this approach in locally advanced NSCLC. (orig.)

    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

    Purpose: Prospectively designed randomized clinical study was undertaken to assess the efficacy of simultaneous application of irradiation, Mitomycin C, and Bleomycin in treatment of patients with inoperable head and neck carcinoma. Methods and Materials: Between March 1991 and October 1993, 49 patients with inoperable head and neck carcinoma were randomly assigned to receive either radiation therapy alone (group A) or radiotherapy combined with simultaneous application of Mitomycin C and Bleomycin (group B). Patients in both groups were irradiated five times weekly with 2 Gy to the total dose of 66-70 Gy. Chemotherapy regimen included intramuscular application of Bleomycin 5 units twice a week, with the planned dose being 70 units and Mitomycin C 15 mg/m 2 applied intravenously after delivery of 9-10 Gy of irradiation. The application of Mitomycin C was planned to be repeated on last day of radiotherapy in the dose of 10 mg/m 2 . In attempt to enhance the effect of chemotherapeutic drugs, patients in group B received also Nicotinamide, Chlorpromazine, and Dicoumarol. Results: The difference in complete response rate between both treatment groups (24% in group A and 63% in group B) was statistically significant (p = 0.015). The difference in response rate was much more pronounced in patients with oropharyngeal carcinoma only (18% in group A compared to 81% in group B; p = 0.0003), while for all other subgroups added together, there was observed no benefit of multidrug therapy. Median follow-up was 18 months. Disease-free survival of patients in group A (9%) was significantly lower then in group B (48%) (p 0.001). The difference between both treatment groups was even greater in patients with oropharyngeal carcinoma only: disease-free survival of these patients in group B was 66%, while in group A, all recurred (p = 0.00001). Conclusion: From results of our prospective randomized study it seems that the group of patients that received multidrug treatment with

    To evaluate the efficacy of postoperative radiotherapy (RT) on local failure-free survival (LFFS), distant metastasis-free survival (DMFS) and overall survival (OS) in patients with localized primary soft tissue sarcoma (STS) and to identify prognostic factors. Between January 2000 and July 2010, 220 consecutive patients with localized primary STS, who received conservative surgery with or without postoperative RT, were enrolled in the study. Survival curves were constructed by the Kaplan-Meier method and log-rank test was used to assess statistical significance. Multivariate analysis was applied to identify the prognostic factors. After a median follow-up of 68 months (range, 5–127 months), the 5-year LFFS, DMFS and OS were 70.0, 78.2 and 71.2 %, respectively. Tumor size, histological subtypes, margin status and postoperative RT were independent predictors for OS. Postoperative RT was associated with a significant reduced local recurrence risk versus surgery alone (hazard ratio [HR] = 0.408, 95 % confidence interval [CI] 0.235–0.707, P = 0.001), with 5-year LFFS of 81.1 and 63.6 %, respectively (log-rank, P = 0.004). The log-rank test showed that postoperative RT had a tendency of improving OS compared with surgery alone, with 5-year OS of 74.8 and 65.0 %, respectively (P = 0.089). Multivariate analysis demonstrated that postoperative RT significantly reduced mortality rate compared with surgery alone (HR = 0.512, 95 % CI 0.296–0.886, p = 0.017), especially in patients with liposarcoma (p = 0.034). Postoperative radiotherapy reduce both local recurrence and STS mortality in patients with localized primary STS. The efficacy of RT on survival warrants further prospective study.

    Swallowing is a complex neuromuscular process that requires anatomical indemnity and an adequate coordination of several organs. Laryngeal cancer treatment may cause swallowing disorders. Traditionally, a high frequency of this type of disorder after surgery has been reported, but no actual data concerning its incidence in patients undergoing radiotherapy for early laryngeal cancer has been published. Aim. To compare swallowing disorders frequency posterior to treatment in early laryngeal cancer patients. Material and Method. Two groups of early laryngeal cancer patients were transversally studied, one treated with vertical partial surgery (CP), and the other treated exclusively with radiotherapy. Each patient had otorhinolaryngological, nasofibroscopic and video fluoroscopic evaluations after treatment. Differences between groups were compared using the - square test. Results. Twenty patients per group were entered in this study, predominantly males of similar age. Both groups presented a high incidence of aspiration symptoms (55% in RT and 35% in CP). There were no significant differences between both groups. Discussion and Conclusion. A high incidence of swallowing disorders in patients treated for early laryngeal cancer was found. It should then be considered as a frequent alteration in this group of patients, either treated with RT or CP

    Curative resection of extrahepatic bile duct cancer and pancreatoduodenal cancer is very difficult, and its long term result is pessimistic. Twenty patients with bile duct cancer (12 resected and 8 non-resected) and 23 patients with pancreatoduodenal cancer (10 resected and 13 non-resected) were treated with extracorporeal Cobalt-60 irradiation following the surgery. The just opposed anterior and posterior ports were used with the field size ranging from 6 x 6 cm to 13 x 14 cm. The delivered doses ranged from 46 to 60 Gy (70 - 108TDF) for bile duct cancer, and from 18 to 66 Gy (28 - 104TDF) for pancreatoduodenal cancer. On one of resected and 4 of non-resected patients with pancreatoduodenal cancer, the therapeutic schedule could not be pursued completely because of decreased leucocytes and emaciation. The postoperative survivals were compared between the cases with and without adjunctive radiotherapy. The longest and mean survivals of the patients with resected bile duct cancer were 41 mos. and 20 mos. respectively, in the irradiated v.s. 21 mos. and 14 mos. in the non-irradiated group. The mean survival of the patients without resection of bile duct cancer was 15 mos. in the irradiated v.s. 6 mos. in the non-irradiated group; one resected case has survived more than 61 mos. after radiotherapy and is still alive. The mean survival after resection of pancreatoduodenal cancer was 16 mos. in the irradiated v.s. 11 mos. in non-irradiated group, and 3 in the former are still alive, one having survived the longest 50 mos. The longest and mean survival of the patients without resection of pancreatoduodenal cancer were 22 mos. and 8 mos. respectively v.s. 7 mos. and 4 mos. of the non-irradiated patients. Advantageous effects of radiotherapy combined with surgery for bile duct cancer and pancreatoduodenal cancer were observed throughout this clinical study. (author)

    Purpose: To retrospectively analyze the outcomes, toxicity, quality of life, and voice quality of patients with T3 laryngeal cancer treated with radiotherapy and to identify subgroups of patients in whom the addition of chemotherapy to radiotherapy is necessary. Methods and Materials: Between March 1996 and November 2009, 170 consecutive patients with T3 tumor were treated with (chemo)radiotherapy. Endpoints of the study were local control (LC), locoregional control (LRC), disease-free survival (DFS), overall survival (OS), late toxicity, quality of life, and voice handicap index. Results: After a median follow-up time of 32 months (range, 7–172), the 3-year actuarial rates of LC, LRC, DFS, and OS were 73%, 70%, 64%, and 61%, respectively, and the 5-year figures were 68%, 65%, 60%, and 49%, respectively. At last follow-up, 84 patients (49.5%) were still alive, 65 of them (77.3%) without local progression. Laryngectomy was performed in 16 patients, leaving 49 patients with anatomic organ preservation, corresponding to an actuarial laryngectomy-free survival of 58.3% at 3 years. The figures for patients treated with chemoradiotherapy and radiotherapy alone were 76.8% and 53.5%, respectively (p = 0.001). Chemoradiotherapy was the only significant predictor for LC on multivariate analysis. The overall 5-year cumulative incidence of late Grade ≥2 toxicity was 28.2%. Chemoradiotherapy, compared with radiotherapy alone, resulted in slight increase in late toxicity and slight deterioration of quality of life and voice-handicap-index scores. However, the differences were statistically not significant. Conclusion: The addition of chemotherapy to radiotherapy in T3 laryngeal cancer significantly improved LC and laryngectomy-free survival without statistically significant increases in late toxicity or deterioration of quality of life or voice handicap index.

    Background. Ionising radiation and cytostatic agents used in cancer therapy exert damaging effects on normal tissues and induce a complex response at the cellular and molecular levels. Cytokines and adhesion molecules are involved in this response. Methods. Published data on the given topic have been reviewed. Results and conclusions. Various cytokines and adhesion molecules, including tumor necrosis factor α, interleukins- 1,-2,-4, and -6, interferon γ, granulocyte macrophage- and macrophage- colony stimulating factors, transforming growth factor β, platelet-derived growth factor, insulin-like growth factor I, fibroblast and epidermal growth factors, platelet-activating factor, intercellular adhesion molecule-1, vascular cell adhesion molecule-1, E- and P-selectins are involved in the response of normal tissues to ionizing radiation- and chemotherapy- induced normal tissues damage and are co-responsible for some side effects of these treatment modalities, including fever, anorexia and fatigue, suppression of hematopoiesis, both acute and late local tissue response.

Prospective longitudinal studies of 93 patients with oropharyngeal cancer treated with definitive chemotherapy-intensity-modulated radiotherapy (IMRT). Observer-rated dysphagia (ORD), patient-reported dysphagia (PRD), and patient-reported xerostomia (PRX) assessment of the swallowing mechanics by videofluoroscopy (videofluoroscopy score), and salivary flow rates, were prospectively assessed from pretherapy through 2 years. ORD grades ≥2 were rare and therefore not modeled. Of patients with no/mild videofluoroscopy abnormalities, a substantial proportion had PRD that peaked 3 months posttherapy and subsequently improved. Through 2 years, highly significant correlations were observed between PRX and PRD scores for all patients, including those with no/mild videofluoroscopy abnormalities. Both PRX and videofluoroscopy scores were highly significantly associated with PRD. On multivariate analysis, PRX score was a stronger predictor of PRD than the videofluoroscopy score. Xerostomia contributes significantly to PRD. Efforts to further decrease xerostomia, in addition to sparing parotid glands, may translate into improvements in PRD. © 2015 Wiley Periodicals, Inc.

    Purpose: To evaluate the activity of palifermin (rHuKGF) in a murine model of mucosal damage induced by a radiotherapy/chemotherapy (RT/CT) regimen mimicking treatment protocols used in head-and-neck cancer patients. Methods and Materials: A model of mucosal damage induced by RT/CT was established by injecting female BDF1 mice with cisplatin (10 mg/kg) on Day 1; 5-fluorouracil (40 mg/kg/day) on Days 1-4, and irradiation (5 Gy/day) to the head and neck on Days 1-5. Palifermin was administered subcutaneously on Days -2 to 0 (5 mg/kg/day) and on Day 5 (5 mg/kg). Evaluations included body weight, organ weight, keratinocyte growth factor receptor expression, epithelial thickness, and cellular proliferation. Results: Initiation of the radiochemotherapeutic regimen resulted in a reduction in body weight in control animals. Palifermin administration suppressed weight loss and resulted in increased organ weight (salivary glands and small intestine), epithelial thickness (esophagus and tongue), and cellular proliferation (tongue and salivary glands). Conclusions: Administration of palifermin before RT/CT promotes cell proliferation and increases in epithelial thickness in the oral mucosa, salivary glands, and digestive tract. Palifermin administration before and after RT/CT mitigates weight loss and a trophic effect on the intestinal mucosa and salivary glands, suggesting that palifermin use should be investigated further in the RT/CT settings, in which intestinal mucositis and salivary gland dysfunction are predominant side effects of cytotoxic therapy

    Introduction: patients with head and neck neoplasia usually show malnutrition or a nutritional risk, because of common symptoms like: dysphagia, odynophagia and xerostomia. Objective: this study aimed to verify the impact of using amino glutamine in patients with head and neck neoplasia and under radiotherapy and chemotherapy treatment concomitantly. Methods: the research was quantitative, cross-sectional, descriptive and exploratory. The data was collected from nutritional evaluation, and patients chart consultation. The patients were divided in a control group (without use of glutamine) and a test group (with use of glutamine). 16 patients, 13 of which were men and three were women, participated in the research. Results: The control group presented mucositis grades I to IV while patients who used the amino glutamine showed mucositis grades I to II only. It could be observed that the Nutritional Risk Index decreased, which represents higher nutritional risk in patients from the control group only. In patients who used glutamine, this decrease was not significant. Conclusion: these results suggest that the use of glutamine in patients with head and neck tumors and under antineoplastic therapy helps to maintain their nutritional stage and to prevent mucositis throughout their treatment, mainly grades III and IV, which prevents adequate and regular eating and nourishment.

    To investigate treatment outcome and long term complication after surgery and radiotherapy (RT) for pituitary adenoma. From 1990 to 2009, 73 patients with surgery and RT for pituitary adenoma were analyzed in this study. Median age was 51 years (range, 25 to 71 years). Median tumor size was 3 cm (range, 1 to 5 cm) with suprasellar (n = 21), cavernous sinus extension (n = 14) or both (n = 5). Hormone secreting tumor was diagnosed in 29 patients; 16 patients with prolactin, 12 patients with growth hormone, and 1 patient with adrenocorticotrophic hormone. Impairment of visual acuity or visual field was presented in 33 patients at first diagnosis. Most patients (n = 64) received RT as postoperative adjuvant setting. Median RT dose was 45 Gy (range, 45 to 59.4 Gy). Median follow-up duration was 8 years (range, 3 to 22 years). In secreting tumors, hormone normalization rate was 55% (16 of 29 patients). For 25 patients with evaluable visual field and visual acuity test, 21 patients (84%) showed improvement of visual disturbance after treatment. The 10-year tumor control rate for non-secreting and secreting adenoma was 100% and 58%, respectively (p < 0.001). Progression free survival rate at 10 years was 98%. Only 1 patient experienced endocrinological recurrence. Following surgery, 60% (n = 44) suffered from pituitary function deficit. Late complication associated with RT was only 1 patient, who developed cataract. Surgery and RT are very effective and safe in hormonal and tumor growth control for secreting and non-secreting pituitary adenoma

    Purpose: Our center contributed 183 patients to the Asian-Oceanian Clinical Oncology Association (AOCOA) multicenter randomized trial comparing induction chemotherapy (CT) followed by radiotherapy (RT) vs. RT alone in patients with locoregionally advanced undifferentiated nasopharyngeal carcinoma (NPC). In a preliminary report no difference in terms of overall survival or relapse-free survival was found between the 2 treatment arms. To study the long-term outcome and patterns of failure after CT for NPC, we analyzed our own center data for which a uniform radiation treatment protocol was adopted and a longer follow-up time was available. Methods and Materials: Between September 1989 and August 1993, a total of 183 patients were recruited into the AOCOA randomized study from our center. Patients with newly diagnosed NPC of Ho's T3 disease, N2-N3 disease, or with neck node size of at least 3 cm were eligible. Stratification was made according to the nodal size (≤3 cm, >3-6 cm, > 6 cm). Patients were randomized to receive 2-3 cycles of CT with cisplatin 60 mg/m 2 and epirubicin 110 mg/m 2 D1 followed by RT or RT alone. Four patients were excluded from the current analysis (2 died before treatment, 2 received treatment elsewhere). The remaining 179 patients were randomized to the two treatment arms, with 92 to the CT arm and 87 to the RT arm. Two patients in the CT arm had RT only, and all patients completed radiation treatment. Overall survival (OAS), relapse-free survival (RFS), local relapse-free survival (LRFS), nodal relapse-free survival (NRFS), and distant metastases-free survival (DMFS) were analyzed using Kaplan-Meier method and significance of survival curve differences calculated using log-rank test. Analysis was performed based on the intent-to-treat. Results: The median follow-up was 70 months. At the time of analysis, 50% of patients in the CT arm and 61% in the RT arm had relapse, while 32% in the CT arm and 36% in the RT arm had died of the disease

    The role of elective nodal irradiation (ENI) in radiotherapy for esthesioneuroblastoma (ENB) has not been clearly defined. We analyzed treatment outcomes of patients with ENB and the frequency of cervical nodal failure in the absence of ENI. Between August 1996 and December 2007, we consulted with 19 patients with ENB regarding radiotherapy. Initial treatment consisted of surgery alone in 2 patients; surgery and postoperative radiotherapy in 4; surgery and adjuvant chemotherapy in 1; surgery, postoperative radiotherapy, and chemotherapy in 3; and chemotherapy followed by radiotherapy or concurrent chemoradiotherapy in 5. Five patients did not receive planned radiotherapy because of disease progression. Including 2 patients who received salvage radiotherapy, 14 patients were treated with radiotherapy. Elective nodal irradiation was performed in 4 patients with high-risk factors, including 3 with cervical lymph node metastasis at presentation. Fourteen patients were analyzable, with a median follow-up of 27 months (range, 7-64 months). The overall 3-year survival rate was 73.4%. Local failure occurred in 3 patients (21.4%), regional cervical failure in 3 (21.4%), and distant failure in 2 (14.3%). No cervical nodal failure occurred in patients treated with combined systemic chemotherapy regardless of ENI. Three cervical failures occurred in the 4 patients treated with ENI or neck dissection (75%), none of whom received systemic chemotherapy. ENI during radiotherapy for ENB seems to play a limited role in preventing cervical nodal failure. Omitting ENI may be an option if patients are treated with a combination of radiotherapy and chemotherapy. Copyright © 2011 Elsevier Inc. All rights reserved.

    The author report a study aimed at assessing the tolerance and efficiency of a technique which has been used for some years and which comprises the implantation of Gliadel wafers in the operative bed before performing a concomitant radiotherapy and chemotherapy with temozolomide, followed by six adjuvant chemotherapy sessions with the Stupp protocol. Four women and seven men have been implanted with Gliadel wafers. Only one patient did not have the concomitant chemo-radiotherapy. The global survival and global survival without progression have been assessed. Even though the obtained results are encouraging, the concomitant chemo-radiotherapy had to be stopped for three patients due to haematological consequences. Short communication

    The aim of this study was to compare the outcomes of surgery and stereotactic body radiotherapy (SBRT) for elderly clinical stage I non-small cell lung cancer (NSCLC) patients. Patients ≥80 years of age with clinical stage I NSCLC between August 2008 and December 2014 were treated either surgery or SBRT. Propensity score matching was performed to reduce bias in various clinicopathological factors. Surgery was performed in 57 cases and SBRT in 41 cases. In the surgery group, the operations included 34 lobectomies and 23 sublobar resections. In the SBRT group, 27 cases were given 48 Gy in 4 fractions, and 14 were given 60 Gy in 10 fractions. Similar characteristics were identified in age (82 years), gender (male:female ratio 2:1), tumor size (2.2 cm), carcinoembryonic antigen (3.6 ng/ml), Charlson comorbidity index (1), Glasgow prognostic scale (0), and forced expiratory volume in 1 s (1.7 L) after matching. Before matching, the 5-year overall survival (OS) in surgery (68.3%) was significantly better than that in SBRT (47.4%, p = 0.02), and the 5-year disease-specific survival (DSS) (94.1%, 78.2%, p = 0.17) was not significantly different between the groups. The difference in the 5-year OS became non-significant between the matched pairs (57.0%, 49.1%, p = 0.56). The outcomes of surgery and SBRT for elderly patients with the early stage NSCLC were roughly the same.

    Treatment of elderly cancer patients has gained importance. One question regarding the treatment of metastatic spinal cord compression (MSCC) is whether elderly patients benefit from surgery in addition to radiotherapy? In attempting to answer this question, we performed a matched-pair analysis comparing surgery followed by radiotherapy to radiotherapy alone. Data from 42 elderly (age > 65 years) patients receiving surgery plus radiotherapy (S + RT) were matched to 84 patients (1:2) receiving radiotherapy alone (RT). Groups were matched for ten potential prognostic factors and compared regarding motor function, local control, and survival. Additional matched-pair analyses were performed for the subgroups of patients receiving direct decompressive surgery plus stabilization of involved vertebrae (DDSS, n = 81) and receiving laminectomy (LE, n = 45). Improvement of motor function occurred in 21% after S + RT and 24% after RT (p = 0.39). The 1-year local control rates were 81% and 91% (p = 0.44), while the 1-year survival rates were 46% and 39% (p = 0.71). In the matched-pair analysis of patients receiving DDSS, improvement of motor function occurred in 22% after DDSS + RT and 24% after RT alone (p = 0.92). The 1-year local control rates were 95% and 89% (p = 0.62), and the 1-year survival rates were 54% and 43% (p = 0.30). In the matched-pair analysis of patients receiving LE, improvement of motor function occurred in 20% after LE + RT and 23% after RT alone (p = 0.06). The 1-year local control rates were 50% and 92% (p = 0.33). The 1-year survival rates were 32% and 32% (p = 0.55). Elderly patients with MSCC did not benefit from surgery in addition to radiotherapy regarding functional outcome, local control of MSCC, or survival. (orig.)

    Purpose: To determine whether a change in treatment policy to conformal, elective nodal radiotherapy and concurrent high-dose cisplatin improved survival for cervical esophageal cancer patients. Methods and Materials: All cervical esophageal cancer patients treated between 1997 and 2005 were restaged (1983 American Joint Committee on Cancer criteria). Patients treated before 2001 (previous cohort [PC]) were compared with those treated from 2001 onward (recent cohort [RC]). The PC institutional chemoradiotherapy protocol was 54 Gy in 20 fractions within 4 weeks, with 5-fluorouracil (1,000 mg/m 2 ) on Days 1-4 and either mitomycin C (10 mg/m 2 ) or cisplatin (75 mg/m 2 ) on Day 1. The RC institutional chemoradiotherapy protocol was conformal radiotherapy, 70 Gy in 35 fractions within 7 weeks, to the primary tumor and elective nodes, with high-dose cisplatin (100 mg/m 2 ) on Days 1, 22, and 43. Results: The median follow-up was 3.1 years (PC, 8.1 and RC, 2.3). Of 71 patients (25 women and 46 men), 21 of 29 in the PC and 29 of 42 in the RC were treated curatively (curative subgroup, n = 50). Between the two groups, no differences in overall survival or locoregional relapse-free survival were seen. The overall survival rate at 2 and 5 years was 35% (range, 24-47%) and 21% (range, 12-32%) in the whole group and 46% (range 32-60%) and 28% (range, 15-42%) in the curative group, respectively. In the curative group, no statistically significant prognostic factors were found. Trends toward better locoregional relapse-free survival were seen in women (2-year rate, 73% vs. for men, 36%; p = 0.08) and in patients aged >64 years (2-year rate, 68% vs. age ≤64 years, 34%; p = 0.10). Conclusion: No survival improvement could be demonstrated after changing the treatment policy to high-dose cisplatin-based, conventionally fractionated conformal chemoradiotherapy. Female gender and older age might predict for better outcomes

    The importance of absent neoplastic epithelium in specimens from cytoreductive surgery (CRS) is unknown. This study aimed to investigate the prevalence and prognostic value of histopathology without neoplastic epithelium in patients treated with CRS and hyperthermic intraperitoneal chemotherapy (HIPEC). Data were extracted from medical records and histopathology reports for patients treated with initial CRS and HIPEC at Uppsala University Hospital, Sweden, between 2004 and 2012. Patients with inoperable disease and patients undergoing palliative non-CRS surgery were excluded from the study. Patients lacking neoplastic epithelium in surgical specimens from CRS, with or without mucin, were classified as "neoplastic epithelium absent" (NEA), and patients with neoplastic epithelium were classified as "neoplastic epithelium present" (NEP). The study observed NEA in 78 of 353 patients (22 %). Mucin was found in 28 of the patients with NEA. For low-grade appendiceal mucinous neoplasms and adenomas, the 5-year overall survival rate was 100 % for NEA and 84 % for NEP, and the 5-year recurrence-free survival rate was 100 % for NEA and 59 % for NEP. For appendiceal/colorectal adenocarcinomas (including tumors of the small intestine), the 5-year overall survival rate was 61 % for NEA and 38 % for NEP, and the 5-year recurrence-free survival rate was 60 % for NEA and 14 % for NEP. Carcinoembryonic antigen level, peritoneal cancer index, and completeness of the cytoreduction score were lower in patients with NEA. A substantial proportion of patients undergoing CRS and HIPEC have NEA. These patients have a favorable prognosis and a decreased risk of recurrence. Differences in patient selection can affect the proportion of NEA and hence explain differences in survival rates between reported series.

    Background. To investigate the patterns of relapse following intensity modulated radiotherapy (IMRT) given after radical surgery for oral and oropharyngeal squamous cell cancer. Patients and methods. One hundred and two patients with oral or oropharyngeal cancer were treated with radical surgery followed by IMRT up to a mean total dose of 60 Gy between years 2001 and 2007. Thirty-nine of the patients (%) also received concomitant weekly cisplatin. Forty of the patients had oral and 62 had oropharyngeal cancer. Data on the tumour, patient and treatment factors were collected. Following therapy the patients were followed by clinical examination, endoscopy and MRI/CT at 2- to 3-months interval up to 2 years and thereafter at 6-month intervals. Results. The mean follow-up time of the patients was 55 months (range, 26-106 months). The rate for local tumour control for the whole cohort was 92.2%: 87.5% for oral cancer patients and 96.7% for oropharyngeal cancer patients. The 5-year disease specific survival was 90.2% and 5-year overall survival 84.3%. During the follow-up eight locoregional recurrences were observed, three at the primary tumour site and one at regional nodal site and four at both sites. The mean time to primary tumour recurrence was seven months (range, 2-10 months) and to nodal recurrence seven months (range, 2-12 months). Distant metastasis occurred in six (6%) patients. The factors associated with poor prognosis were the primary tumour size and tumour site with oral cancers having worse outcome. The treatment was well tolerated with no unexpected toxicities. The most frequent late toxicity was dysphagia necessitating permanent PEG in five patients. This was correlated with the advanced primary tumour size and resulting in wide tumour excision and reconstruction. Conclusions. Surgery combined with postoperative radiotherapy given as IMRT results in low level of tumour recurrence

    Incidence of, and baseline characteristics associated with delirium in patients after cytoreduction surgery-hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), were subject of investigation. The study was conducted among a consecutive series of prospectively included patients who underwent CRS-HIPEC at the University Medical Center Groningen, Groningen, the Netherlands, between February 2006 and January 2015. A chart-based instrument for delirium during hospitalization was used to identify patients with symptoms of delirium who were not diagnosed by a psychiatrist during admission. Uni- and multivariate logistic regression analyses were performed. Data of 136 patients were included in the analysis. Median age was 60 years (range: 18-76) and 50 (37%) patients were male. During hospitalization, 38 (28%) patients were diagnosed with delirium. Factors that differed significantly between the patients with and without delirium by univariate analysis were included in multivariate analysis. Multivariate analysis showed that after adjustment for age and complications other than delirium, having three or more organs resected and the CRP serum levels were independent predictors for delirium (OR: 3.97; 95% 1.24-12.76; OR: 1.01; 95% 1-1.01, respectively). This report shows an incidence of 28% of delirium, occurring after CRS-HIPEC and suggests a role for systemic inflammation in the development of postoperative delirium. © 2017 Wiley Periodicals, Inc.

    The aim was to evaluate the feasibility and the effectiveness of neoadjuvant systemic chemotherapy using FLOT - protocol followed by cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC) followed by systemic chemotherapyand in patients with peritoneal carciriomatosis (PC) from gastric cancer. Twenty six (median age 53 years, range 39 - 71) were scheduled for three cycles of neoadjuvant systemic chemotherapy using bi-weekly FLOT - protocol followed by CRS + HIPEC. Thereafter 3 additional cycles of FLOT were given. During HIPEC in Colliseum technique Oxaliplatin was given in a dosage of 200 mg/m2 and Docetaxel in a dosage of 80 mg/m2. All patients underwent cytoreductive surgery plus HIPEC. Peritoneal Cancer index was > 15 in 3 cases only. Complete resection could be carried out in all cases (CC-O 18, CC-18). Postoperative complication rate was 23% with no mortality withi
