    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

    Treatment of renal cell carcinoma has evolved considerably over the last few years. While total nephrectomy is necessary at times, nephron-sparing surgery, with a goal of renal function preservation, should always be considered. Although open partial nephrectomy is considered the gold standard approach for nephron-sparing surgery, laparoscopic- or robotic-assisted techniques allow urologists to perform renal surgery less invasively, with excellent long-term oncological outcomes. Cryotherapy and radiofrequency ablation are less invasive management approaches for carefully selected patients with small renal masses. Active surveillance should be considered in elderly or patients who are unfit for surgery. Ultimately, the method chosen for management of a renal mass is an informed decision made by the physician and patient. PMID:26892144

    Full Text Available Basal cell carcinoma originates from pluripotent cells of basal layer of epiderm, external covering of hair follicles, sebaceous glands or other skin adnexa. It is characterized by local infiltrating and sometimes destructive growth. There are several types of basal cell carcinomas that may be manifested in over 12 clinical forms. Surgical treatment depends to a large extent on the histological type, localization and its clinical manifestation. The analysis included 250 patients of both gender and different age, operated for basal cell carcinoma. Clinical characteristics of basal cell carcinoma and the width of the excision were described. It was concluded that the width of the excision of basal cell cancer was in relation to histological type. .

Angiogenesis inhibitors have been shown to be very effective for the treatment of metastatic renal cancer cell. Axitinib is a third-generation inhibitor of vascular endothelial growth factor receptor and is currently being developed for the treatment of various malignancies. The pharmacokinetic properties of axitinib may have a selective therapeutic effect, with minimal adverse reactions and enhanced safety. In a large Phase III study of previously treated patients with metastatic renal cell carcinoma, axitinib achieved a longer progression-free survival than sorafenib with an acceptable safety profile and good quality of life. This review focuses on the pharmacology, pharmacokinetics, and clinical activity of axitinib in the current treatment of renal cell carcinoma. The role of axitinib in the adjuvant and/or neoadjuvant setting needs to be evaluated in further clinical trials.Keywords: axitinib, renal cell carcinoma, vascular endothelial growth factor receptor, angiogenesis

This breakthrough in science led to the development of a variety of small molecules inhibiting the VEGF-dependent angiogenic pathway, such as sunitinib and sorafenib. These agents prolong overall and progression-free survival, respectively. The result was the development of robust front-line therapies which ultimately fail and are associated with disease progression. In this setting, there existed an unmet need for developing second-line therapies for patients with refractory metastatic renal cell carcinoma (MRCC. Everolimus (RAD 001 is an oral inhibitor of the mammalian target of rapamycin (mTOR pathway. The double-blind, randomized, placebo-controlled phase III trial of everolimus (RECORD-1 conducted in MRCC patients after progression on sunitinib or sorafenib, or both, demonstrated a progression-free survival benefit favoring the study drug (4.9 months vs 1.9 months, HR 0.33, 95% CI 0.25 to 0.43, P ≤ 0 0.001.

    International Nuclear Information System (INIS)

    Continuous follow-up of 244 patients treated for primary invasive squamous cell carcinoma of the vulva during a 20-year period (1960-1979) resulted in the detection of recurrent (or persistent) disease in 60 cases. Forty-one of these cases developed local or regional recurrence, or both, later than six months after treatment, and an analysis of the result of retreatment in this group is presented. Twenty-nine had local recurrences, nine regional metastases and three local recurrences and regional metastases. The treatment technique for local recurrences was surgery, in a few cases combined with irradiation and chemotherapy. In approximately one-third of the cases, this treatment resulted in long-term or permanent cure. In cases of regional metastases the prognosis was often extremely poor, but treatment normally gave good palliation although of short duration. (orig.)

    The risk of developing renal cell carcinoma (RCC) increases with age, and given the constant gain in life expectancy of the general population, both localized RCC and metastatic RCC (mRCC) are more frequently observed in the elderly population. The elderly are a heterogeneous group of patients often characterized by the presence of comorbidities, different compliance to treatment and polypharmacy. Here we review the available data with the aim to analyze the safety and efficacy of new targeted therapies (TTs) in elderly mRCC patients. TTs seem to be effective in both older and younger patients, but elderly patients appear to show reduced tolerance to treatments compared to younger patients. Prospective trials are needed to better understand how to manage mRCC in elderly patients. PMID:26654225

  3. The present approach to treatment of renal cell carcinoma

    International Nuclear Information System (INIS)

    Until the turn of the millennium, metastatic renal cell carcinoma (mRCC) was regarded as one of the most refractory cancers; highly resistant to both radiation and systemic therapy, and only small group of patients responded to immune modulation. Involved targeted therapies, which influence specific signal transduction pathways of tumor formation and progression, opened new options of treatment to give patients a new hope. After the first experiences with the new biologic agents we can claim, that these patients have improved a quality of life, provided stabilization of disease and prolong life of patients, but the cure is not available. However, there are so many studies with target therapies in RCC, but the most correct algorithm of treatment does not exist. Targeted therapies rarely achieve remission, prevailing a stabilisation of disease so patients have to undergo chronic treatment. In choice of optimal treatment is necessary to regard for quality of life, so usually the winner is the drug with the lowest toxic potential. (author)

    Full Text Available Temsirolimus is a novel inhibitor of mammalian target of rapamycin (mTOR, which is a central regulator of the response of tumour cells to growth and survival signals. When heavily pretreated patients with advanced solid tumours received intravenous (IV temsirolimus over a broad dose range, antitumour activity was observed in various tumour types, including advanced renal cell carcinoma (RCC. A study of singleagent temsirolimus in patients with cytokine-refractory metastatic RCC subsequently demonstrated antitumour activity and encouraging progression- free survival and overall survival. Temsirolimus was generally well tolerated over the 3 dose levels tested (25 mg, 75 mg or 250 mg weekly as a 30-minute IV infusion. The most frequent grade 3 or 4 treatment-related adverse events reported (n=110 were hyperglycemia (17%, hypophosphatemia (13%, anemia (9%, and hypertriglyceridemia (6%. Results from a randomized phase III study that enrolled previously untreated patients with advanced RCC and poor-prognostic features have recently demonstrated a significant increase in overall survival (p=0.0089 for patients who received temsirolimus 25 mg IV, 30-minute infusion once weekly compared with those who received interferon-alpha up to 18 million units subcutaneously thrice weekly. On the basis of improved survival, temsirolimus can be considered a first-line treatment for patients with advanced RCC.

    Full Text Available Mehmet Hepgur, Sarmad Sadeghi, Tanya B Dorff, David I Quinn Division of Medical Oncology, University of Southern California Norris Comprehensive Cancer Center, Keck School of Medicine, Los Angeles, CA, USA Abstract: Renal cell carcinoma (RCC is an aggressive malignancy compared to other urological malignancies and has been associated with poor responses to conventional cytotoxic chemotherapy. Interferon-a and interleukin-2 were previously utilized in a limited number of patients with good performance status due to toxicity and safety issues. Over the last decade, through advances in the understanding of the biology and pathology of RCC, the important role of vascular endothelial growth factor (VEGF in RCC has been identified. Data from randomized trials have led to the approval of first-generation tyrosine kinase inhibitors (TKIs sorafenib, sunitinib, and pazopanib; however, these agents inhibit a wide variety of kinase targets and are associated with a range of adverse effects. More recently, a new generation TKI, axitinib, has been approved by the US Food and Drug Administration. Tivozanib is a novel TKI, which is a potent inhibitor of VEGF-1, VEGF-2, VEGF-3, c-kit, and PDGR kinases, with a more restricted target spectrum. Phase II and III studies have demonstrated significant activity and a favorable safety profile as an initial targeted treatment for advanced RCC. This review examines the emerging data with tivozanib for the treatment of advanced RCC. Preclinical investigations as well as Phase I, II, and III data are examined; data on the comparative benefits of tivozanib are reviewed. Finally, we discuss the future potential of tivozanib in combination, biomarkers associated with tivozanib response, and acquisition of resistance and nonkidney cancer indications.

    Survival time of the patients with bronchogenic small cell anaplastic cancer was studied. Combined treatment with six-drug combination chemotherapy ''METVFC'' (mitomycin C + cyclophosphamide + toyomycin + vincristine + 5-FU + cytosine arabinoside) and radiotherapy (5,000 rads in total) was given to 14 cases of limited disease of small cell carcinoma. Median survival was 8 months, one year and two year survival rates were 47% and 27%, respectively. Combined treatment with METVFC and small dose radiotherapy of 100 or 200 rads irradiation 4 hours before chemotherapy, followed by remission consolidation of 3,000 -- 4,000 rads radiotherapy, thereafter second line chemotherapy of ''COAM'' (cyclophosphamide + vincristine + ACNU + methotrexate) was given to 4 cases of limited disease of small cell carcinoma. All cases survived more than 1.5 years and two of them have retained complete remission more than 1.5 years. There are 6 cases with small cell carcinoma survived more than 3 years out of total 128 cases. They are all those of limited disease. They received combined treatment of chemotherapy and radiotherapy simultaneously or alternatively, followed by remission maintenance chemotherapy. One case of them died from cancer. Two cases died from another disease without lung cancer. Three cases survived healthy more than 3 to 8 years. In the limited disease, small cell carcinoma of the lung might be curable if the complete remission could continue more than three years. (author)

This study was aimed to investigate the clinical experience and management of patients with SCC of the urinary tract. We collected data of patients who were diagnosed with genitourinary SCC (GSCC between 2002 and 2013 and were treated in the Fudan University Shanghai Cancer Center. A total of 18 patients were diagnosed with GSCC of which 10 originated from the prostate, seven from the bladder and one from the adrenal gland. The mean follow-up time was 15.5 months and progression-free survival (PFS was 9.3 months. Primary tumor resection was attempted in 13 of 18 patients (72.2% in whom radical surgery was performed in six of 14 (42.9% limited disease patients. Most of the patients (13, 72.2% received cisplatin-based chemotherapy. Patients who had normal lactic dehydrogenase (LDH levels showed a significantly higher median PFS and overall survival (OS compared with patients with high LDH levels (P = 0.030, P= 0.010. Patients with limited disease treated with a radical operation experienced a non-significant (P = 0.211 longer PFS compared with patients who were not treated, but this reached statistical significance after analyzing OS (P = 0.211, P= 0.039. Our patients showed a poor prognosis as reported previously. Serum LDH levels beyond the normal range indicate a poor prognosis. For GSCC patients who are diagnosed with limited disease, radical surgery is strongly recommended along with cisplatin-based chemotherapy.

    To study the clinical biocharacteristics of primary esophageal small-cell carcinoma (PESC) and factors influencing prognosis and to find rational indications for combination therapy. Methods: To analyze the clinical materials of 47 patients who had undergone an operation with PESC and to compare it with those patients with esophageal squamous-cell carcinoma (ESCC) or primary esophageal adenocarcinoma (PEAC). Results: The overall resectability, morbidity and 30-day mortality rates of PESC were 93.6%, 17.0%and 2.1% respectively, similar to those of ESCC or PEAC. TNM staging and lymph node metastasis were the major determinants influencing long-term survival. Tumor length, depth of tumor invasion and type of operation had little influence on long-term prognosis. The 5-year survival rate of PESC was 7.5%, which was much lower than that of ESCC and PEAC (P<0.01). Among the 42 deceased patents, one died of anastomotic leakage and the others died of remote metastasis and recurrence. Adjuvant chemotherapy did not help improve the patients' long-term survival. Conclusions: Compared with ESCC and PEAC, PESC is the most malignant type with early lymphatic and hematogenous metastases and poor prognosis. Lymph node metastasis is the major factor influencing the prognosis. Patients in stage 0, I and II a of PESC are indicated for surgical resection, while those in stage II b, III or IV should be managed with non-surgical combined therapy.

    The efficacy of hypofractionated radiation protocol for feline facial squamous cell carcinoma was evaluated. Hypofractionated radiation therapy was applied to five cats showing single or multiple facial squamous cell carcinomas, in a total of ten histologically confirmed neoplastic lesions. Of the lesions, two were staged as T1, four as T2, two as T3, and two as T4. The animals were submitted to four radiation fractions from 7.6 to 10 grays each, with one week intervals. The equipment was a linear accelerator with electrons beam. The cats were evaluated weekly during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 40% of the lesions had complete remission, 40% partial remission, and 20% did not respond to the treatment. Response rates were lower as compared to other protocols previously used. However, hypofractionated radiation protocol was considered safe for feline facial squamous cell carcinoma. (author)

    Full Text Available Abstract Background Renal cell carcinoma (RCC represents approximately 3% of all adult cancers and is more common in males. Systemic treatment for RCC has improved following the introduction of tyrosine kinase inhibitors, such as sunitinib. The molecular targets of sunitinib are receptor tyrosine kinases (RTKs. Moreover, sunitinib has an additional anti-angiogenic effect through its inhibition of the vascular endothelial growth factor receptor activation. Case presentation We present a case of intra-abdominal abscess formation mimicking disease progression, in a patient with metastatic renal cell carcinoma during sunitinib treatment. Conclusion In the advancing era of molecular therapy of solid tumours, sunitinib has demonstrated significant efficacy in the post-cytokine setting treatment of metastatic renal cancer. Concurrently, however, increasing evidence has emerged to indicate that this class of drugs exert profound immunomodulatory effects on T cells and play major roles in immune tumor surveillance.

    Full Text Available Renal cell carcinoma (RCC is the most common renal tumor and accounts for 3% of all adult cancers. The treatment of metastatic renal cell carcinoma (mRCC has recently evolved from being a predominantly cytokine-based treatment to the use of targeted agents, which include Sorafenib, Sunitinib, Bevacizumab, Temsirolimus, Everolimus, Pazopanib, Axitinib, and most recently Tivozanib. Despite these advances mRCC remains a major health problem. Additional studies are needed to optimize the use of these agents in both advanced and early stage disease, either in combination or sequentially. In addition the development of biomarkers should be a priority in order to guide rational tailored development of emerging agents. This literature review was conducted using PubMed, Medline, and Cochrane databases for articles published until January 2013. Abstracts from relevant meeting of the American Society of Clinical Oncology and the European society of medical oncology were also included.

    2004-01-01

    Artemisinin (AR) is a widely used antimalarial drug. Recently, additional uses for AR as an anticancer drug were discovered. Using TUNEL, immunohistochemistry (IHS) markers and flow cytometry techniques, we evaluated the effect of AR and 5-FU on HPV 16 immortalized and transformed human gingival epithelial (IHGK) cells. The results of TUNEL showed that AR-treated IHGK cells consisted of 82% positive cells, while 5-FU-treated cells consisted of 18% positive cells. The IHS markers demonstrated positive staining with Bax p53, CD40 and CD40L in AR-treated cells and negative staining with Bcl-2. 5-FU-treated cells demonstrated a profile similar to AR but with less intensity. Cell cycle by flow cytometry results showed that only 5-FU-treated cells demonstrated a significant S-phase rate increase to 45%. In conclusion, our results indicate that AR is cytotoxic to transformed oral epithelial cells through apoptosis, while 5-FU is cytotoxic primarily through cell toxicity. PMID:15330155

  10. Interdependence of Gemcitabine Treatment, Transporter Expression, and Resistance in Human Pancreatic Carcinoma Cells

    Full Text Available Gemcitabine is widely used as first-line chemotherapeutic drug in the treatment of pancreatic cancer. Our previous experimental chemotherapy studies have shown that treatment of human pancreatic carcinoma cells with 5-fluorouracil (5-FU alters the cellular transporter expression profile and that modulation of the expression of multidrug resistance protein 5 (MRP5; ABCC5 influences the chemoresistance of these tumor cells. Here, we studied the influence of acute and chronic gemcitabine treatment on the expression of relevant uptake and export transporters in pancreatic carcinoma cells by reverse transcription-polymerase chain reaction (RT-PCR, quantitative RT-PCR, and immunoblot analyses. The specific role of MRP5 in cellular gemcitabine sensitivity was studied by cytotoxicity assays using MRP5-overexpressing and MRP5-silenced cells. Exposure to gemcitabine (12 nM for 3 days did not alter the messenger RNA (mRNA expression of MRP1, MRP3, MRP5, and equilibrative nucleoside transporter 1 (ENT1, whereas high dosages of the drug (20 µM for 1 hour elicited up-regulation of these transporters in most cell lines studied. In cells with acquired gemcitabine resistance (up to 160 nM gemcitabine, the mRNA or protein expression of the gemcitabine transporters MRP5 and ENT1 was upregulated in several cell lines. Combined treatment with 5-FU and gemcitabine caused a 5- to 40-fold increase in MRP5 and ENT1 expressions. Cytotoxicity assays using either MRP5-overexpressing (HEK and PANC-1 or MRP5-silenced (PANC1/shMRP5 cells indicated that MRP5 contributes to gemcitabine resistance. Thus, our novel data not only on drug-induced alterations of transporter expression relevant for gemcitabine uptake and export but also on the link between gemcitabine sensitivity and MRP5 expression may lead to improved strategies of future chemotherapy regimens using gemcitabine in pancreatic carcinoma patients.

  13. Treatment of squamous cell carcinoma of the maxillary alveolus and hard palate

    International Nuclear Information System (INIS)

    We report the treatment and clinical results for squamous cell carcinoma of the maxillary alveolus and hard palate. Fifty-nine cases with squamous cell carcinoma of the maxillary alveolus and hard palate treated between April 2001 and March 2009 were reviewed. For the initial treatment, 3 patients received brachytherapy, 43 patients underwent surgical resection alone, and 13 patients underwent surgical resection combined with radiotherapy or chemoradiotherapy. Local failure developed in 11 patients (18.6%), of which 7 patients were salvaged with further surgery. Five-year cumulative survival rates were 89.1% for all patients, 93.9% for the surgery-alone group and 71.3% for the preoperative treatment group. Further study is necessary to decide the optimal strategy and indications for preoperative treatment. Cervical lymph node metastasis was histologically confirmed in 16 patients (27.1%). Contralateral cervical lymph node metastasis developed in 8 patients. Five-year cumulative survival rates were 94.0% for pN0, 83.3% for pN1 and pN2b, and 70.0% for pN2c patients. Metastasis to the contralateral cervical lymph node should be considered in patients with maxillary alveolus and hard palate carcinoma. (author)

    Full Text Available It has been held studying of the remote results of treatment of 80 patients sick of a bazalioma by 30 % glyciphon ointment in the Republican Oncologic Dispensary of the Ministry of Health of Republic of Tatarstan. It is established that daily use of glyciphon ointment during the 20– 30 days cures patients with primary tumours, both single, and initially-plural I and II stages, in 98,3 % cases. The preparation is effective at recidivations of bazalioma arising after radiotherapy, surgical treatment, criotherapy. The using at recidivations after the combined treatment is inexpedient. Reduction of an exposition of ointment from 24 hours till 6 hours gives good clinical effect with absence of relapses of recidivations of tumors.

  15. Radiation therapy for the treatment of feline advanced cutaneous squamous cell carcinoma

    International Nuclear Information System (INIS)

    The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T1, and six as T4 according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

Traditionally patients with metastatic RCC have been treated with immunotherapy which has limited efficacy. The multikinase inhibitors sunitinib, sorafenib and pazopanib, the VEGF antibody bevacizumab in combination with interferon and the mTOR inhibitor temsirolimus have all been shown to prolong progression-free survival in phase III studies. Here we review another mTOR inhibitor, everolimus (Afinitor®; Novartis, USA which was approved in March 2009 by the US FDA for treatment of targeted-therapy refractory metastatic renal cell cancer. The phase III study of everolimus (the RECORD study was terminated early after a significant difference in efficacy was noted in the treatment arm with everolimus (progression-free survival of 4.0 months in patients on the treatment arm vs 1.9 months in the placebo arm. The most common adverse events were stomatitis, pneumonitis, fatigue and infections.

    International Nuclear Information System (INIS)

    To determine how surgical treatment of the neck for N0 cases of squamous cell carcinoma in the floor of the mouth should be done, the pattern of occult cervical lymph node metastases was evaluated. The number of N0 cases without local failure from 1970 to 1999 was 53 (48 males and 5 females, average age 60.3 years old). T classification was as follows: T1: 14 patients, T2: 35 patients, T3: 4 patients. Initial treatment consisted of surgery only (29 patients), radiation therapy only (7 patients), surgery and radiation therapy (14 patients), surgery and chemotherapy (3 patients). Elective neck dissection (ENT) was performed in 16 patients. Histological cervical lymph node metastasis was detected in 18.9%, 2 of 16 patients who underwent ENT and 8 of 37 patients who underwent therapeutic neck dissection (TND). Frequency of secondary cervical lymph node metastasis by initial treatment and T classification distinction was not different. The sites of metastasis were level III except one case. The 5-year survival rate was 73.1% in the ENT group and 66.9% in the TND group. The results suggest that surgical treatment of the neck is not necessary for initial treatment for N0 cases of squamous cell carcinoma in the floor of the mouth. (author)

    A review of the literature suggested that prolonged treatment time may lessen the probability of cure for patients with advanced squamous cell carcinoma of the upper aerodigestive tract. To shorten treatment time, rapid sequence treatment (RST) was devised in which chemotherapy, surgery, and irradation were administered in a total treatment time of 8 weeks. Twelve patients were treated and followed 3 years or longer. Medical complications were minor. Osteonecrosis occurred in each of the first five patients and was the only major complication of the protocol. Surgical techniques were modified, and no additional patient developed osteonecrosis. No patient developed local or regional recurrence. Two patients developed distant metastases and three other patients developed second primaries. Absolute survival was 50%. Rapid sequence treatment is an aggressive and potentially hazardous protocol that yielded encouraging results in this pilot study.

  4. Clinical evaluation of multimodal treatment for squamous cell carcinoma of the maxillary sinus

    International Nuclear Information System (INIS)

    Seventy-seven patients with squamous cell carcinoma of the maxillary sinus were treated with radiotherapy and surgery (with or without intra-arterial infusion chemotherapy) from 1969 to 1986 at Tokyo Women's Medical College. The treatment given to the subjects was broadly separated into three categories: Treatment I (1969-1974), Treatment II (1975-1977), and Treatment III (1978-1986). Treatment I consisted of surgery and radiotherapy; Treatment II consisted of multimodal treatment by surgery and radiotherapy with 5-FU intra-arterial infusion chemotherapy (IAIC) from the superficial temporal artery; Treatment III consisted of surgery and radiotherapy with Adriamycin IAIC replacing 5-FU IAIC. Radiotherapy involved a total dose of 60 Gy/6 weeks in Treatment I as the standard, 50 Gy/5 weeks with 5-FU (250 mgx20 times/4 weeks) in Treatment III. Surgery by antrotomy was performed before radiotherapy and IAIC, and Denker's operation was done after radiotherapy with IAIC. The influence of patients' age, sex, T stage and N stage were examined as prognostic factors and no statistically significant differences were seen among each treatment periods. The 2-year control rate was 29% in period I, 27% in period II, and 58% in period III. The 5-year cumulative survival rate was 13% for period I, 40% for period II, and 54% for period III; the incidence of side effects during radiotherapy did not appear to increase, and the severity was at a tolerable level considering the results. However, late complications were seen in 6 cases (cataract, 5; obstinate sinusitis, 1). Thus, the study indicates that multimodal treatment using Adriamycin IAIC can minimize face deformity and allows effective function-saving treatment for carcinoma of the maxillary sinus. (author)

  5. Sunitinib treatment for patients with clear-cell metastatic renal cell carcinoma: clinical outcomes and plasma angiogenesis markers

    International Nuclear Information System (INIS)

    Sunitinib is a protein tyrosine kinase-inhibitor targeting VEGFR, c-kit and PDGFR. It has been approved for the treatment of metastatic renal-cell carcinoma and gastrointestinal stromal tumors. Although it has been shown to prolong disease-free and overall survival in renal-cell carcinoma patients, only 70% of the treated population receive a clinical benefit (CB) from the treatment. Markers that could predict clinical benefit to sunitinib would be an important aid in monitoring and following their treatment. We assessed the outcome and plasma proangiogenic factors in patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib in our institution. We have treated 42 patients with metastatic clear-cell renal carcinoma with sunitinib. Plasma concentrations of VEGF-A, sVEGFR2 and PDGF were determined by ELISA. At the time of analysis 39 patients were evaluable for response and 30 patients had obtained a clinical benefit (CB). Median progression-free survival was 268 days (8.93 months) and median overall survival was 487 days (16.23 months). Interestingly, disease stabilization or objective response resulted in comparable overall survival. Most treatment-related adverse events were of mild-to-moderate intensity with one treatment-related death. Plasma sVEGFR2 and PDGF levels had no predictive value. Fold-increase in plasma VEGF was significantly lower in patients that obtained a CB as compared to patients that progressed after two cycles of treatment. Plasma VEGF did not increase in patients with initial CB at the time of progression. Sunitinib showed substantial activity in mRCC. Disease stabilization or objective response resulted in comparable overall survival and both outcomes should be considered positive. Fold-increase in plasma VEGF predicts for CB and could be a candidate marker. Progression after initial CB is not associated with elevated plasma VEGF, implying a different mechanism of resistance

    Current standard of care for muscle-invasive urothelial cell carcinoma (UCC) is surgery along with perioperative platinum-based chemotherapy. UCC is sensitive to cisplatin-based regimens, but acquired resistance eventually occurs, and a subset of tumors is intrinsically resistant. Thus, there is an unmet need for new therapeutic approaches to target chemotherapy-resistant UCC. Yes-associated protein (YAP) is a transcriptional co-activator that has been associated with bladder cancer progression and cisplatin resistance in ovarian cancer. In contrast, YAP has been shown to induce DNA damage associated apoptosis in non-small cell lung carcinoma. However, no data have been reported on the YAP role in UCC chemo-resistance. Thus, we have investigated the potential dichotomous role of YAP in UCC response to chemotherapy utilizing two patient-derived xenograft models recently established. Constitutive expression and activation of YAP inversely correlated with in vitro and in vivo cisplatin sensitivity. YAP overexpression protected while YAP knockdown sensitized UCC cells to chemotherapy and radiation effects via increased accumulation of DNA damage and apoptosis. Furthermore, pharmacological YAP inhibition with verteporfin inhibited tumor cell proliferation and restored sensitivity to cisplatin. In addition, nuclear YAP expression was associated with poor outcome in UCC patients who received perioperative chemotherapy. In conclusion, these results suggest that YAP activation exerts a protective role and represents a pharmacological target to enhance the anti-tumor effects of DNA damaging modalities in the treatment of UCC.

    Forty-two patients with advanced squamous cell carcinoma of the vulva were treated with a combination regimen of bleomycin 180 mg and external irradiation 30-45 Gy. Twenty patients had primary lesions, and 22 patients had recurrent disease. Fifteen (75%) of the patients with primary disease showed objective response (five complete and ten partial response). Four underwent surgery. Of these, one is alive after 60 months with no evidence of disease. Two have died of unrelated causes without signs of recurrence. Seventeen relapsed and died of carcinoma of the vulva. Median survival for patients treated for primary disease was 8.0 months. Thirteen (59%) of 22 patients treated for recurrence showed objective response (two complete and eleven partial responses). None underwent surgery. All these patients died of carcinoma of the vulva. Median survival was 6.4 months. Toxicity was acceptable, and there were no treatment-related deaths. Even taking into account that our patients had very advanced disease, the results are disappointing. An increase of the radiation dose beyond the maximum of 45 Gy given, and more aggressive surgery, might have improved the results. (orig.).

    A 69-year-old man with a 100 pack-year history of smoking developed gross hematuria. His medical history included hypertension, a silent myocardial infarction, and a cerebrovascular accident complicated by seizures. Cystoscopy and biopsy showed a 4-cm mass at the right ureteral orifice positive for a high-grade papillary transitional cell carcinoma (TCC) with muscularis propria invasion (Fig 1). The computed tomography (CT)/positron emission tomography (PET) scan of the chest, abdomen, and pelvis showed hydronephrosis and hydroureter with marked cortical thinning and multiple bilateral PET-avid pulmonary nodules, with the largest in the left upper lung measuring 3.0 × 2.5 cm (Figs 2A, 3A), biopsy of which showed invasive high-grade urothelial carcinoma. The patient consented to join a clinical trial for metastatic TCC (USON [US Oncology Network study] 06040) involving treatment with gemcitabine, cisplatin, and sunitinib (GCS) 37.5 mg per day. Four days later, he experienced a 10-day hospitalization for acute pancreatitis and neutropenia. Sunitinib was discontinued, and he completed four additional cycles of GC. CT/PET showed that the right ureteral mass and all lung nodules had regressed or disappeared (Figs 2B, 3B). The largest remaining lung nodule at 1.4 cm showed no metabolic activity. He underwent a radical cystoprostatectomy and right nephroureterectomy, disclosing residual high-grade urothelial carcinoma infiltrating the full thickness of the ureteral wall. There was carcinoma in situ of the bladder, and 42 nodes were negative for cancer. The surgery was followed by a small, uncomplicated myocardial infarction. A scheduled left thoracotomy to remove the remaining nodule was cancelled. No additional chemotherapy was administered, and the patient remains free of recurrence 2 years from initiation of chemotherapy. The 1.4-cm nodule has calcified and remains stable and metabolically inactive. He has no sequelae of chemotherapy or surgery, with a creatinine

  13. Hyperthermia and PARP1-inhibition for sensitization of radiation and cisplatin treatment of cervical carcinoma cells

    International Nuclear Information System (INIS)

    Ionizing radiation causes single and double strand breaks (SSBs and DSBs). DSBs are among the most critical DNA lesions and can be repaired via either non-homologous end joining (NHEJ) in which PARP1, Ku70 and DNA-PKcs are important, or homologous recombination (HR), where BRCA2 and Rad51 are essential. Hyperthermia disturbs HR by temporary inactivation of BRCA2. Cisplatin disrupts NHEJ and PARP1-inhibitor blocks Poly-(ADP-ribose)polymerase- 1, which is important in SSB repair, NHEJ and backup-NHEJ. Our goal was to investigate the additional effectiveness of hyperthermia and PARP1-inhibition on radiation and/or cisplatin treatment. Cervical carcinoma cells (SiHa) were treated at different temperature levels levels (41.0-43.0℃, PARP1-inhibitor (100 μM; NU1025), gamma-irradiation doses (0-8 Gy) or cisplatin (1'R for 1 h). Clonogenic assays were carried out to measure survival and γH2AX staining was used to visualize DSBs. To elucidate mechanisms of action expression levels of DNA repair proteins BRCA2 and DNA-PKcs were investigated after 42.0℃ (1 h) using western blot. Combined hyperthermia and radiation resulted in an increased number of γH2AX foci as compared to radiation alone. Hyperthermia treatment in combination with cisplatin and PARP1 inhibitor and with radiation and PARP1 inhibitor significantly decreased cell survival. Western blot demonstrated a decreased expression of BRCA2 protein at 30 min after hyperthermia treatment. Adding PARP1-inhibitor significantly improves the effectiveness of combined hyperthermia radiotherapy and combined hyperthermia-cisplatin treatment on cervical carcinoma cells. Hyperthermia affects DNA-DSB repair as is indicated by increased γH2AX foci numbers and decreased BRCA2 expression. (author)

  16. Merkel cell carcinoma in patients on long-term immunosuppressive treatment

    International Nuclear Information System (INIS)

    Merkel cell carcinoma is a rare form of skin cancer of neuroendocrine origin that has been described as one of the most aggressive cutaneous malignancies. The annual incidence is estimated to be 0.23 per 100,000 in the white population. Most cases occur in elderly people, the average age being 69 years. MCC is most common in sun-exposed areas, with nearly 50% of lesions developing within the head and neck. It typically appears as a red-blue nodule with a shiny surface, often with overlying telangiectasia. One of the most important etiological factors is long-term immunosuppression, mainly in organ transplant recipients. Nowadays it is speculated that previously unknown polyoma virus - Merkel cell polyoma virus (MCV) - can be another probable etiologic agent of the disease. This paper presents the latest data on the pathogenesis of Merkel cell carcinoma and analyses the differences between MCC occurring in patients undergoing immunosuppressive treatment and MCC developing in immunocompetent patients.

  17. Treatment Trends and Outcomes of Small-Cell Carcinoma of the Bladder

    International Nuclear Information System (INIS)

    Purpose: Treatment for small-cell carcinoma of the bladder is largely guided by case reports, retrospective reviews, and small prospective trials. This study aimed to study outcomes using a large population-based database. Methods: The Surveillance, Epidemiology, and End Results–Medicare database (1991–2005) was used to analyze how different treatment combinations of specific bladder surgeries, chemotherapy, and radiation affected patient outcomes. Trends in the use of these combinations over time were also analyzed. Results: A total of 533 patients were retrieved from the database. A bladder-sparing approach involving transurethral resection of the bladder tumor (TURBT) combined with chemotherapy and radiation yielded no significant difference in overall survival compared with patients undergoing at least a cystectomy (of whom over 90% received radical cystectomy) with chemotherapy (p > 0.05). The analysis of treatment trends indicated that these two general strategies for cure combined to account for fewer than 20% of patients. A majority of patients (54%) received TURBT as their only surgical treatment, and a subset analysis of these patients indicated that chemotherapy played a role in all stages of disease (p < 0.05) whereas radiation improved overall survival in regional-stage disease (p < 0.05). Conclusion: Relatively few patients with small-cell carcinoma of the bladder receive potentially curative therapies. Chemotherapy should be a major component of treatment. Cystectomy and bladder-sparing approaches represent two viable strategies and deserve further investigation to identify the patients who may benefit from organ preservation or not. In addition, the role of radiation in regional-stage disease should be investigated further, because it positively affects survival after TURBT.

    Objective: To explore the treatment of clinically negative neck (CN0) patients with squamous cell carcinoma of the tongue. Methods: 165 CN0 patients with squamous cell carcinoma of the tongue from 1985 to 2002 were investigated retrospectively. Parts of the patients staged at T1, T2 and T3 underwent resection of primary lesion followed by neck observation, and other patients staged above T2 or at T1 but without follow-up were treated with elective neck dissection (END). All patients were followed up for more than 3 y or until their death. Results: Lymphatic metastasis was identified histologically after operation in 33 of 120 patients treated with END, and 9 of 45 patients treated with resection of primary lesion alone. The overall rate of occult lymphatic metastasis was 25.45%, which increased with the elevating of clinical T stage. The overall rate of neck uncontrolled death was 20.00% for observation group and 5.00% for END group, and significant difference was found between them (P<0.05). For T1 patients in the two groups, the rate of neck uncontrolled death was 7.71% and 4.00% respectively, and no significance was found between them (P>0.05). When stage T2 and T3 were considered as middle stage together, significant difference (P<0.05) could be obtained between observation (70.00%) and END group (0%). Conclusion: The occult metastasis rate of squamous cell carcinoma of tongue increases with the elevating of clinical stage, and elective neck dissection could be considered for N0 patients staged over T2 to improve neck control and survival rate; and regional resection alone of primary lesion could be considered for T1N0 patients to improve quality of life if closely followed up is conducted.

  20. Evaluating the safety and efficacy of axitinib in the treatment of advanced renal cell carcinoma

    International Nuclear Information System (INIS)

    Axitinib is a tyrosine kinase inhibitor of vascular endothelial growth factor receptor, platelet-derived growth factor receptor-α, and c-kit. Phase I studies demonstrated 5 mg twice daily as the recommended starting dose with notable effects seen in renal cell carcinoma, an observation confirmed in Phase II trials. The trial of comparative effectivess of axitinib versus sorafenib in advanced renal cell carcinoma (AXIS) was an international randomized Phase III study designed for registration purposes, compared axitinib to sunitinib. This trial randomized 723 patients with metastatic kidney cancer to axitinib or sunitinib in the second-line setting and demonstrated a median progression-free survival of 6.7 months for axitinib versus 4.7 months for sorafenib (P<0.0001). Clinical benefit was detected regardless of prior therapy, but no overall survival benefit has been observed. Axitinib is well tolerated without a significant effect on quality of life. The most common grade 3 toxicities are hypertension (16%), diarrhea (11%), and fatigue (11%), with other notable side effects being anorexia, nausea, hand–foot syndrome, and rash. Patients who developed diastolic blood pressure >90 mmHg were noted to have significantly longer median overall survival and overall response rates when compared to normotensive patients. Therefore, the manufacturer recommends escalating the twice-daily dose to 7 mg and 10 mg, as tolerated, if there is no significant increase in blood pressure on treatment. Currently, axitinib is approved for use in the second-line setting for patients with metastatic renal cell carcinoma. Research is ongoing in other disease settings

    Full Text Available PURPOSE: The objective of this study was to compare the estimated cost of clinical and surgical treatment for basl cell carcinoma of the eyelid. METHODS: This was a pilot study of 12 patients with basal cell carcinoma receiving treatment with 5% imiquimod cream at the ocular plastic surgery center, medical school University of São Paulo (HC-FMUSP, Brazil. The cost of clinical treatment was estimated based on the time of treatment and amount of medication consumed by patients in the home setting. The cost of surgical treatment was estimated by ophthalmologists with experience in reconstructive plastic surgery based on analysis of images of the same patients. Surgeons responded to a questionnaire with four questions about surgical technique, surgical materials required, estimated duration of surgery and type of anesthesia. RESULTS: Immunotherapy lasted from 8 to 12 weeks.All patients reported each coldstored sachet with 5% imiquimod cream lasted 3 days.According to the institution, a box with 12 sachets costs BRL 480.00. Patients required 1.58-3.11 boxes for complete treatment, corresponding to a total cost of BRL 758.401,492.80. Based on image analysis, surgeons evaluated surgery would require 1-3 hours. The estimated cost of surgery room and staff was BRL 263.00, to which the cost of supplies was added. Thus, the total cost of surgical treatment was BRL 272.61-864.82. On the average, immunotherapy was 57,64% more costly than surgical treatment. CONCLUSIONS: Malignant eyelid tumors are a common finding in clinical ophthalmology. Surgery is still the treatment of choice at our institution, but immunotherapy with 5% imiquimod cream may be indicated for patients with multiple lesions or high surgical risk and for patients declining surgery for reasons of fear or esthetic concerns.The ability to estimate costs related to the treatment of malignant eyelid tumors is an important aid in the financial planning of health care institutions.

    Squamous cell carcinoma arises from multiple anatomic subsites in the head and neck region. The risk factors for development of cancers of the oral cavity, oropharynx, hypopharynx, and larynx include tobacco exposure and alcohol dependence, and infection with oncogenic viruses is associated with cancers developing in the nasopharynx, palatine, and lingual tonsils of the oropharynx. The incidence of human papillomavirus-associated oropharyngeal cancer is increasing in developed countries, and by 2020, the annual incidence could surpass that of cervical cancer. The treatment for early-stage squamous cell cancers of the head and neck is generally single modality, either surgery or radiotherapy. The treatment for locally advanced head and neck cancers is multimodal, with either surgery followed by adjuvant radiation or chemoradiation as indicated by pathologic features or definitive chemoradiation. For recurrent disease that is not amenable to a salvage local or regional approach and for metastatic disease, chemotherapy with or without a biological agent is indicated. To date, molecular testing has not influenced treatment selection in head and neck cancer. This review will focus on the changing epidemiology, advances in diagnosis, and treatment options for squamous cell cancers of the head and neck, along with data on risk stratification specific to oropharyngeal cancer, and will highlight the direction of current trials.

  6. Everolimus – a new approach in the treatment of renal cell carcinoma

    International Nuclear Information System (INIS)

    With the increasing understanding of the biology of the disease and the development of targeted therapy, there has been a paradigm shift in the treatment of clear cell metastatic renal cell carcinoma (mRCC). Traditionally patients with metastatic RCC have been treated with immunotherapy which has limited efficacy. The multikinase inhibitors sunitinib, sorafenib and pazopanib, the VEGF antibody bevacizumab in combination with interferon and the mTOR inhibitor temsirolimus have all been shown to prolong progression-free survival in phase III studies. Here we review another mTOR inhibitor, everolimus (Afinitor®; Novartis, USA) which was approved in March 2009 by the US FDA for treatment of targeted-therapy refractory metastatic renal cell cancer. The phase III study of everolimus (the RECORD study) was terminated early after a significant difference in efficacy was noted in the treatment arm with everolimus (progression-free survival of 4.0 months in patients on the treatment arm vs 1.9 months in the placebo arm). The most common adverse events were stomatitis, pneumonitis, fatigue and infections. We review Phase I–III data with a particular emphasis on safety data and patient focused outcomes

Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449, a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery.

  9. Treatment of patients with Huerthle cell thyroid carcinoma using [Lu-177-DOTAO, Tyr3]octreotate

    International Nuclear Information System (INIS)

    Full text of publication follows. Aim: Huerthle cell thyroid carcinoma (HCTC) is a variant of follicular thyroid carcinoma. Although radioiodine (I-131) is given for ablation of the thyroid remnant to enable serum thyroglobulin levels for follow-up, it is rarely used for the treatment of residual or metastatic disease, related to the Huerthle cell tumour's poor capacity of taking up radioiodine. Since thyroid tumour cells express somatostatin receptors, peptide receptor radionuclide therapy using radiopharmaceuticals such as [Lu-177-DOTA0,Tyr3]octreotate (Lu-177-octreotate) has been proposed as a potential treatment option. Materials and Methods: 15 patients with pathology proven HCTC treated with Lu-177-octreotate between January 2000 and April 2012 were studied. CT or MRI scans were analysed using SWOG criteria for response outcome. Thyroglobulin levels were analysed and a decrease of more than 50% was considered as a significant biochemical response. All patients had received radioiodine to ablate the thyroid remnant. Six patients received an additional treatment dose of I-131 (total cumulative dose range: 0.7 to 14.8 GBq I-131). Results: Acute side effects such as nausea, vomiting, pain, and hair loss were present during 22%, 2%, 8% and 27% of all administrations respectively. WHO grade 3 bone marrow toxicity for both platelets and leukocytes was present in 2% of all treatment cycles. No long-term side effects such as myelodysplasia or kidney failure were found during a median follow-up of 25 months (range 2-119 months). Twelve patients received the intended cumulative dose (22.2-29.6 GBq) of Lu-177-octreotate whereas 3 did not, due to persisting thrombocytopenia, concomitant cardiac atrial fibrillation, or to the diagnosis of rectal adenocarcinoma as a second primary tumour. In 11 out of the 12 remaining patients sufficient follow-up data were available for evaluation. Four (36%) patients had a partial response (PR) at 3 months after the last treatment

Patients and method. - This retrospective study concerns 271 hypopharyngeal squamous cell carcinomas, compiled in the Carcinologic Surgery Department of Head and Neck of the Salah-Azaiz Institute over a period of 25 years (from 1977 to 2002). The average age of the patients was of 56 years; sex-ratio was on average of 1.2 (man/woman). The indication of a curative treatment was initially retained for 149 (55%) patients, who were the only ones retained for the analysis of results. Results. - We retained the indication of a protocol including surgery and post-operating radiotherapy for 26.2% of the patients. Post-operation mortality rate was 5.1%; the operating rate of morbidity was 46.2%. For 13.5% of the patients, post-operating radiotherapy was permanently interrupted because of a gradual deterioration of the patients' health in the course of treatment. We retained the indication of exclusive radiotherapy for 59.7% of the patients. The average age was of 56 years and the sex-ratio of 1.2. The external radiotherapy was conventional. Radiotherapy had to be permanently interrupted in progress in 32.6% of cases on account of an deterioration of the patients' health; the rate of morbidity of the radiotherapy was 33.3%. We indicated a protocol of conservation of organ with induction chemotherapy for 21 patients (14.1%). The average age was of 53 years (28-65 years) and sex-ratio (man/woman) of 0.5. The global survival was 25.5% at one year, 18.1% at two years, 11.4% at three years and 7.4% at five years. All the patients selected for chemotherapy died in the course of treatment. The rates of survival in two and five years according to protocols surgery-radiotherapy and exclusive radiotherapy were

    Advanced basal cell carcinoma (aBCC) encompasses locally advanced BCC (laBCC) and metastatic BCC (mBCC), two variants of BCC with a limited prevalence worldwide. Treatment of aBCC is still very challenging for the lack of randomized controlled trials/guidelines and the scarcity of available therapeutic options. Based on current data, surgical procedures and radiotherapy are considered the treatments of choice for aBCC although often associated with substantial morbidity and/or deformity. Alternatively, systemic chemotherapy and electrochemotherapy can be used but standardized treatment schedules and randomized clinical trials are not available for both treatments. In recent years, novel tumor-specific and pathogenesis-based molecules have been developed for the treatment of aBCC. A number of clinical trials have recently demonstrated the efficacy and tolerability of vismodegib, the first novel systemic, anti-Smo target cancer therapy for aBCC. Additional molecules currently investigated in phase I-III clinical trials include other Smo antagonists and itraconazole. The contribution of a multidisciplinary team composed of dermatologists, surgeons, oncologists, pathologists, radiologists and radiotherapists is required to deal with the spectrum of issues that emerge from managing patients affected by aBCC.

    The aim of the study was to evaluate the effectiveness of combined treatment of locally advanced lung cancer with the use of neoadjuvant chemotherapy and surgery with the use of pre- and intraoperative photodynamic therapy. 20 patients with IIIa (n=7) and IIIb (n=13) stage of non-small cell lung carcinoma were included. At the time of diagnosis the surgical treatment was decided to abstain because of the trachea invasion in 9 patients, wide mediastinal invasion in 2 patients and contralateral mediastinal lymph nodes metastases in 2 patients; pneumonectomy was not possible due to the poor respiratory function in 7 patients. Neoadjuvant therapy included 3 courses of chemotherapy and endobronchial photodynamic therapy. During the operation, along with the lung resection (pneumonectomy - 15, lobectomy - 5), photodynamic therapy of the resection margins were carried out. No adjuvant treatment was done. Preoperative treatment led to partial regress of the disease in all cases; the goal of surgery was the complete tumor removal. No complications of the photodynamic therapy were observed. 18 surgical interventions were radical and two non-complete microscopically (R1). Postoperative morbidity was 20%, one patient died due to massive gastrointestinal bleeding. The average follow-up period was 18 months: 19 patients were alive, of them 18 with no signs of the disease recurrence. The first experience of the combined use of neoadjuvant chemotherapy and surgery with pre- and intraoperative photodynamic therapy demonstrates safety and efficacy of the suggested treatment tactics.

    A case is presented of a patient with a skin basosquamous cell carcinoma of the frontal region infiltrating the cerebral tissue and with a widespread unresectable regional metastatic ulceration of the left parotid region. The patient underwent combined palliative treatment: surgical coverage of the ulceration by means of a pectoralis mayor flap transposition and radiotherapy. After 18 months of follow-up, no signs of tumour progression were noted, the patient is currently free from pain, no increase in trismus was seen, and a slight gain in weight was recorded. Unresectable cancer is mainly treated by concurrent chemoradiation; radiotherapy, however, is contraindicated in deep neoplastic ulcerations with exposure of large vessels. The data reported suggest that surgical coverage of an unresectable neoplastic ulcer is feasible, and combined with early administration of radiation permits a palliative approach in an otherwise untreatable condition.

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

  18. Critical appraisal of pazopanib as treatment for patients with advanced metastatic renal cell carcinoma

    International Nuclear Information System (INIS)

    The management of renal cell carcinoma (RCC) has undergone significant changes during the past 10 years, with the treatment of metastatic RCC undergoing the most radical changes. These developments reflect an enhanced understanding of this tumor’s underlying biology, which was then translated into the development of a new treatment paradigm. Current therapeutic approaches for the management of patients with metastatic RCC utilize knowledge of histology, molecular abnormalities, clinical prognostic factors, the natural history of this malignancy, and the treatment efficacy and toxicity of available agents. The treatment options available for patients with metastatic RCC have changed dramatically over the past 6 years. Interferon-α and interleukin-2 were the previous mainstays of therapy, but since December 2005, six new agents have been approved in the US for the treatment of advanced RCC. Three are multi-targeted tyrosine kinase inhibitors (TKI) including sunitinib, sorafenib, and pazopanib, two target the mammalian target of rapamycin (temsirolimus and everolimus), and one is a humanized monoclonal antibody (bevacizumab in combination with interferon-α). The current review focuses on the newest TKI available to treat patients with metastatic RCC, pazopanib. The development of this agent both preclinically and clinically is reviewed. The efficacy and safety data from the pivotal clinical trials are discussed, and the potential role of pazopanib in the treatment of patients with metastatic RCC in comparison to other treatment alternatives is critically appraised. This agent has a favorable overall risk benefit, and the available data demonstrate efficacy in patients with metastatic RCC who are either treatment-naïve or cytokine refractory. It therefore represents another alternative for treatment of metastatic RCC patients

  19. Study of the diagnosis and treatment of renal cell carcinoma using monoclonal antibodies

    International Nuclear Information System (INIS)

    Among the potential applications of monoclonal antibodies (Mabs) in the diagnosis and treatment of human cancer is the use in the specific detection of cancer sites and the selective destruction of cancer cells. Fetal kidney was used as an immunogen to develop Mab A6H, which is highly reactive to 16/16 renal cell carcinoma (RCC) cell lines and to 16/19 human RCC specimens. RCC xenografts as small as 40 mg have been imaged clearly in radioimmunoscintigraphy studies using A6H labeled with iodine-131. In Mab-targeted radiotherapy studies, 2 doses of 100-150 uCi 131I-labeled A6H or an 131 I-labeled A6H-C5H cocktail caused tumor regression or tumor growth arrest in >80% of treated mice, while no such effect was observed in mice treated with 131I-labeled control Mab or unlabeled A6H. Internal radiation dosimetry, which was calculated by computer analysis of sequential radioimmunoscintigraphy, showed that A6H delivered approximately 35 rad/uCi of the injected dose to RCC xenografts. When the radiation dose to the tumor was 3000 rad resulted in tumor regression or growth arrest in >85% of mice. A clinical trial using 131I-labeled A6H in the diagnosis and treatment of RCC is now underway at our institution

  1. Combination chemotherapy including high dose methotrexate and radiotherapy, in the treatment of small cell carcinoma of the lung

    International Nuclear Information System (INIS)

    Twenty-nine (88%) of thirty-three patients who were treated with multiple drug chemotherapy, including high dose methotrexate, and radiotherapy for small cell carcinoma of the lung showed significant improvement in their clinical condition and quality of life. Treatment was well tolerated and toxicity acceptable. Cerebral metastases were not detected in any patient on presentation and only developed in three patients (9%). Little information exists regarding the use of high dose methotrexate in small cell carcinoma of the lung. There is no evidence, on the data available, that high dose methotrexate is any more effective than conventional doses. (author)

    Treatment options for localized resectable basal cell carcinoma (BCC) include micrographically controlled surgery, simple excision, curettage, laser ablation, cryosurgery, imiquimod, 5-fluorouracil, photodynamic therapy and radiotherapy. The aim of this study was to assess the preferences of patients with BCC for outcome (cure and recurrence rate, cosmetic outcome, risk of temporary and permanent complications) and process attributes (type of therapy, treatment location, anaesthesia, method of wound closure, duration of wound healing, out-of-pocket costs) of these treatments with conjoint analysis. Participants (n = 124) attached greatest importance to recurrence rate (relative importance score (RIS) = 17.28), followed by cosmetic outcome (RIS = 16.90) and cure rate (RIS = 15.02). Participants with BCC on the head or neck were particularly interested in cosmetic outcome. Those with a recurrence were willing to trade risk of recurrence, treatment location and duration of wound healing for a better cosmetic result. In summary, participants particularly valued cure and cosmetic outcome, although preferences varied with individual and tumour-associated characteristics. PMID:26537095

    Small cell carcinoma of the cervix (SCCC) belongs to the neuroendocrine carcinomas, and it is a rare gynecological tumor of high-potential malignancy. It has a poorer prognosis compared to cervical squamous cancer or adenocarcinoma, and the therapeutic regimen of the disease differs. Diagnosis is based on pathomorphological characteristics, i.e., the small and round cancer cells (oat cell) which are uniform in shape and size, with the immunohistochemical marker helpful for diagnosis. Combined therapy is first recommended. Postoperative chemotherapy with platinum/etoposide (PE), vincristine/adriamycin/cyclophosphamide (VAC) and taxel/carboplatin (TP) can markedly improve the prognosis of early SCCC patients.

    Full Text Available Incidence of basal cell carcinoma (BCC, the most common skin cancer in humans, is rising. Surgery is the mainstay of treatment but there is no standard of care for locally advanced or metastatic disease. Hedgehog signaling proteins are critical for cell growth and differentiation during embryogenesis; Hh pathway is silenced in adults. Dysregulated or aberrant Hh signaling has been implicated in the pathogenesis of BCC. This hyperactive pathway can be inhibited by use of smoothened inhibitors such as vismodegib. Food and drug administration approved this oral, once-daily medication in 2012 to treat adults with metastatic BCC or locally advanced, recurrent BCC after surgery and also for patients with locally advanced BCC who are not candidates for surgery or radiation treatment. Clinical studies have shown it to be highly efficacious and the most common adverse effects include, muscle spasms, alopecia and dysgeusia. Use of targeted biologic modifiers, exemplified by Hh directed therapeutics offer a new hope to patients with high-surgical morbidity or inoperable tumors.

    OBJECTIVE To study the diagnosis and treatment of chromophobe cell renal carcinoma (CCRC). METHODS Three cases of CCRC were studied by analyzing the results of an operation, by light microscopy, immunohistochemistry, Hale's colloidal iron staining and electronmicroscopy (EMC). RFESULTS Doppler ultrasonic and CT features were not specific. Histopathology: Grossly the tumor tissue was homogeneous, light brown in color with central necrotic foci; Light microscopy: Macrocyte, fine reticular cytoplasm with clear cell border; Hale's colloidal iron staining: positive; positive EMA, CK19, vimentin, Ckpan, and negative S-100; EMC: numerous intracyto-plasmic membranous small cysts. All patients were followed up for 14.1-31 months (19.7 months on average), one patient had lung metastasis 11 months after resection of a G,~ tumor, two alive patients had no local recurrences and metastases. CONCLUSIONS CCRC is histo-pathologically, immunohistochemically and electron microscopically distinct from other renal cancers. Surgical tumor removal is the best way for treatment. It is probably a type of cancer with low malignant potential and favorable prognosis.

  6. Usefulness of Photodynamic Therapy as a Possible Therapeutic Alternative in the Treatment of Basal Cell Carcinoma

    Full Text Available Basal cell carcinoma (BCC is the most common cancer in individuals with fair skin type (I–II and steadily increasing in incidence (70% of skin malignancy. It is locally invasive but metastasis is usually very rare, with an estimated incidence of 0.0028%–0.55%. Conventional therapy is surgery, especially for the H region of the face and infiltrative lesions; in case of inoperable tumors, radiotherapy is a valid option. Recently, topical photodynamic therapy (PDT has become an effective treatment in the management of superficial and small nodular BCC. PDT is a minimally invasive procedure that involves the administration of a photo-sensibilizing agent followed by irradiation at a pre-defined wavelength; this determines the creation of reactive oxygen species that specifically destroy target cells. The only major side effect is pain, reported by some patients during the irradiation. The high cure rate and excellent cosmetic outcome requires considering this possibility for the management of patients with both sporadic and hereditary BCC. In this article, an extensive review of the recent literature was made, in order to clarify the role of PDT as a possible alternative therapeutic option in the treatment of BCC.

  7. Nephron sparing surgery as the treatment of choice in renal cell carcinoma

    International Nuclear Information System (INIS)

    Advances in imaging diagnostics have contributed to the frequent detection of small kidney tumours both at an early stage and of low grade. Although radical nephrectomy is still the gold standard in Renal Cell Carcinoma (RCC) treatment, yet it slowly ceases to be the standard approach and open or laparoscopic Nephron Sparing Surgery (NSS) is becoming more and more common. Ai m. The purpose of the study was to determine the functional and oncological outcomes of NSS for RCC basing on an analysis of 108 patients. Material and methods. The patients were divided into two groups: T1a (≤ 4 cm) and T1b (≥ 4 ≤ 7 cm). We performed an analysis of all patients with a minimal follow-up time of 24 months. In the majority of patients the diagnosis was clear cell carcinoma(83.9%). Results. G2 tumours were the most common (51.7%). The cumulative proportion of survivors without local relapse within the operated kidney and/or in the local lymph nodes and without distant metastases after 2 and 3 years was 99% and 93%, respectively. Our results support the fact that in pT1a and pT1b patients NSS is a safe and effective procedure. The size of pT1 tumours has no bearing on 2-year and 3-year recurrence-free survivals. Conclusion. Intraoperative ultrasound allows for further identification of additional neo plasmatic foci and for the use of the best surgical approach. Intraoperative ultrasound is useful in NSS, and especially in those cases, where the tumor lies in the central part of the kidney. (authors)

    AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma (SCC). METHODS: A systematic review was conducted according to the preferred reporting items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in concert. RESULTS: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal SCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal SCC’s are in fact an extension of an anal SCC, and cytokeratin markers are a useful adjunct in this distinction. Staging is most accurately reflected by the tumour-node-metastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external site of primary SCC with metastasis to the rectum. While the

    2016-01-01

    Background Axitinib is a next-generation, selective tyrosine kinase inhibitor targeting the vascular endothelial growth factor receptors. It is approved for the treatment of metastatic renal cell carcinoma (mRCC) based on a demonstrated progression-free survival advantage over sorafenib in the second-line treatment setting. However, given the variety of available targeted therapies for mRCC, appropriate patient selection for the available therapies remains a significant clinical challenge. Purpose This review summarizes the available evidence on the clinical, toxicity, and pharmacologic considerations for determining appropriate patient selection for axitinib therapy. In addition, it describes recent data on the use of predictive biomarkers to guide clinical management. This paper consists of material obtained via PubMed and Medline literature searches through October 2015. Conclusion Axitinib has a well-established role in the management of mRCC. Consistent clinical efficacy has been demonstrated across prognostic risk groups and prior therapeutic exposures. Although axitinib is generally well tolerated, appropriate toxicity management is critical to maximizing drug delivery and optimizing treatment outcomes. Although incident hypertension has been associated with improved clinical outcomes on axitinib, there are currently no validated clinical or genetic predictive biomarkers to guide patient selection.

  10. The role of radiotherapy and chemotherapy in the treatment of merkel cell carcinoma

    International Nuclear Information System (INIS)

    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

  11. The importance of postoperative radiation therapy in the treatment of Merkel cell carcinoma

    International Nuclear Information System (INIS)

    Purpose: To determine the role of postoperative radiation therapy in the treatment of Merkel cell carcinoma (MCC). Methods and Materials: Eighty patients with MCC of the skin were treated with curative intent at the Queensland Radium Institute between 1981 and 1991. Fifty-one patients (63.7%) were referred after initial biopsy for further treatment and 29 patients (36.3%) were referred with locally recurrent disease following primary surgery elsewhere. Thirteen patients (16.3%) presented with nodal disease without a clinically definable primary skin lesion. Results: Of the 80 patients, 38 had undergone surgery (S) alone, 34 surgery plus radiotherapy (S + RT), 7 RT after incomplete S, and 1 patient had chemotherapy (CT) plus RT. Overall survival at 36 months for all patients was 68%. All of the 38 patients treated with S alone relapsed. The median time to recurrence was 5.5 months. Ten of the 34 patients treated with S + RT relapsed. The median time to recurrence was 16.5 months. Of the 80 patients, 55 have relapsed after primary treatment, 25 have developed systemic metastases, and 26 patients have died as a direct result of MCC. Conclusion: Our large series confirms earlier reports from this Institute and highlights the importance of S + RT over S alone in preventing local recurrence of this highly malignant skin cancer

    2014-01-01

    Full Text Available Basal cell carcinomas (BCC on the genital area account for less than 1% of all BCCs. Surgical management is indicated. Recurrence rate of vulvar BCC has been reported to be 10-20%. Mohs micrographic surgery (MMS is a superior surgical option. Other treatments include radiation and topical immuntherapy. Cryosurgery for vulvar BCC has not been reported. We present the case of a 88-year-old Hispanic woman with a vulvar ulcer that was confirmed as BCC by histopathology and treated with liquid nitrogen cryosurgery. Control biopsy was performed on day 90 was negative for BCC. No clinical evidence of recurrence was detected after one year. Although, the vulva is considered to be a high-risk site with respect to BCC and MMS is the gold standard for treatment, the delicate nature of the area may preclude complete removal by a surgical technique without compromising vital anatomical function. Liquid nitrogen cryosurgery uses the effects of extreme cold to effect deep destruction of the tumor and surrounding tissues. This is the first report of a vulvar BCC successfully treated with liquid nitrogen cryosurgery. We suggest this technique could be of benefit as an alternative treatment in cases where excisional procedures cannot be performed.

    Sarcomatoid renal cell carcinoma (SRCC) is an aggressive tumor variant thought to arise predominantly from differentiation of clear cell carcinoma. A few reports of SRCC asso-ciated with non-clear cell tumors led to the presumption that SRCC may arise from any renal cell carcinoma, although direct evidence of this is lacking. We report a case of a 70-year-old male patient, who presented with acute left upper quadrant abdominal pain and was diagnosed to have SRCC after pathological examination...

    Merkel cell carcinoma (MCC) is a rare tumour of the skin of neuro-endocrine origin probably developing from neuronal mechanoreceptors. A collaborative group of multidisciplinary experts form the European Dermatology Forum (EDF), The European Association of Dermato-Oncology (EADO) and the European Organization of Research and Treatment of Cancer (EORTC) was formed to make recommendations on MCC diagnosis and management, based on a critical review of the literature, existing guidelines and expert's experience. Clinical features of the cutaneous/subcutaneous nodules hardly contribute to the diagnosis of MCC. The diagnosis is made by histopathology, and an incisional or excisional biopsy is mandatory. Immunohistochemical staining contributes to clarification of the diagnosis. Initial work-up comprises ultrasound of the loco-regional lymph nodes and total body scanning examinations. The primary tumour should be excised with 1-2cm margins. In patients without clinical evidence of regional lymph node involvement, sentinel node biopsy is recommended, if possible, and will be taken into account in a new version of the AJCC classification. In patients with regional lymph node involvement radical lymphadenectomy is recommended. Adjuvant radiotherapy might be considered in patients with multiple affected lymph nodes of extracapsular extension.

    Topical application of anticancer drugs for the treatment of malignancies represents a new challenge in dermatology, potentially being an alternative therapeutic approach for the efficacious treatment of non-melanoma skin cancer, that is, actinic keratoses, and malignant lesions of the skin caused by ultraviolet radiation. Anti-proliferative and antimitotic drugs, including many of the taxanes, are currently under investigation for the treatment of cutaneous malignant transformation of actinic keratoses, particularly the squamous cell carcinoma. Paclitaxel-loaded ethosomes® are proposed as topical drug delivery systems for the treatment of this pathology due to their suitable physicochemical characteristics and enhanced skin penetration ability for deep dermal delivery. Our in vitro data show that the skin application of paclitaxel-loaded ethosomes® improved the permeation of paclitaxel in a stratum corneum-epidermis membrane model and increased its anti-proliferative activity in a squamous cell carcinoma model as compared to the free drug. The results obtained encouraged the use of the paclitaxel-loaded ethosomes® as the formulation for the potential treatment of squamous cell carcinoma, a malignant transformation of actinic keratoses.

    The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T{sub 1}, and six as T{sub 4} according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

  20. Adjunctive radiotherapy with strontium-90 in the treatment of conjunctival squamous cell carcinoma

    International Nuclear Information System (INIS)

    Squamous cell carcinoma of the ocular conjunctiva is a relatively rare malignancy which is attended by a high rate of local recurrence following simple surgical excision. To date, the management of conjunctival squamous cell cancer has been controversial. From 1950 to 1985, 146 consecutive patients with superficial conjunctival squamous cell cancer were treated at the Queensland Radium Institute. All patients were treated by simple surgical excision of the visible conjunctival lesion followed by adjunctive radiotherapy. Of 140 patients with histologically confirmed squamous cell cancer, 123 were treated with a strontium-90 source, 10 with a radon ring, and 7 with superficial X ray therapy. Standard policy since 1960 has been to deliver an incident dose of 30 Gy in a single fraction within the first 48 post-operative hours to the surgical bed using a strontium-90 source on a stand-off eye applicator. This report will largely focus on the 123 patients who were treated with a strontium-90 source, of whom 107 received 30 Gy, 14 received 40 Gy (pre 1960) and one patient each received 20 and 25 Gy incident dose. Of 131 evaluable patients, there were only 3 who developed local recurrence. All 3 local recurrences developed in elderly men who had presented with extensive superficial primary tumors. Two of the three recurrences occurred in the two patients who were treated with doses less than 30 Gy. Both early and late radiation-induced complications following ablative surgery and treatment with strontium-90 were very uncommon. Three patients developed unsightly conjunctival telangiectasia, 2 patients developed a persistent scleral ulcer and 2 patients developed clinically significant cataracts

    2006-01-01

    Full Text Available Basal cell carcinoma (BCC is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation as an important risk factor for development of illness such as severe solar burns during childhood or adolescence. BCC is mainly located on sun-exposed sites, head and neck being the areas of more incidences; although nose, eyelids and periorbitary tissue are unfavorable due to cosmetic results that BCC involves. Tumors can be classified as nodular, superficial, micronodular, morphea variety, infiltrating, pigmented, metatypic and fibroepithelioma of Pinkus. Several treatment options such as surgical and nonsurgical are available. The goal of treatment is complete excision of the tumor with preservation of surrounding structures in a way aesthetically acceptable. Mohs′ micrographic surgery is the standard treatment for all nonmelanoma skin cancers. Orbital exenteration is also used for treatment of malignancies of ocular tissues, mainly squamous cell carcinoma, sebaceous cell carcinoma and BCC. The tissue beneath the surgical site can be left for second-intention granulation or covered with a cutaneous implant of partial thickness. The case of a 77-year-old patient is presented with BCC of inferior eyelid of 14 years′ duration, formerly managed with radiotherapy; however, due to recurrent illness and invasion to the maxillary antrum, he needed supraestructure maxillectomy with left orbital exenteration.

    Background The tyrosine kinase inhibitors (TKIs) sunitinib, the first targeted agent for the first line treatment of metastatic renal cell carcinoma (RCC), targets the vascular endothelial growth factor (VEGF) pathway. The objective of this study was to investigate the efficacy and safety of sunitinib in treating metastatic clear-cell RCC and to confirm if hypertension is an effective predictive factor.Methods A total of 36 patients with metastatic RCC were enrolled between June 2008 and December 2010. Among them 29 cases were first line therapy and 7 cases were in progression on first-line cytokine or sorafinib therapy. The pathology of all patients was confirmed predominant in clear cell type. Sunitinib mono-therapy was administered in repeated 6-week cycles of daily oral therapy for 4 weeks, followed by 2 weeks off in 34 patients; and 3 patients were administered with 37.5 mg/d continuously until disease progression or unacceptable toxicities occurred. Overall response rate and safety were evaluated. We divided patients into Group A and Group B according to the blood pressure level.Results The median follow-up was 15 months (10 cycles, range 1.5-30.0 months (1-20 cycles)). Ten patients (29.4%)achieved partial responses (PR); 23 patients (67.6%) demonstrated stable disease (SD) lasting >2 cycles. Seventeen patients (50%) developed progressive disease (PD) during follow-up. The median progression-free survival (PFS) was 15 months (range 3.0-28.5) months. A total of 9 patients died; the overall survival has not been reached; the median survival time of the deceased patients was 13 months (range 7-24) months. The most common adverse events were hand-foot syndrome (77.8%), thrombocytopenia (75.0%), hypertension (61.1%) and diarrhea (46.0%). Most adverse events were reversible by treatment interruption. Twenty-two patients (61.1%) developed hypertension; and hypertension was associated with a long time to disease progression and long overall survival

  4. Serum squamous cell carcinoma antigen and CYFRA 21-1 in cervical cancer treatment

    International Nuclear Information System (INIS)

    Purpose: To analyze whether serum squamous cell carcinoma (SCC) antigen and cytokeratin-19 fragments (CYFRA) levels can assist in selecting patients with locally advanced cervical cancer who will benefit from combined treatment or additive surgery. Methods and Materials: Of 114 patients with cervical cancer Stage IB-IV, the first 39 patients received radiotherapy, the following 75 patients received identical radiotherapy plus concomitant chemotherapy (3 cycles of carboplatin and 5-fluorouracil). SCC antigen and CYFRA 21-1 serum levels were measured before treatment, after therapy, and during follow-up. Baseline tumor markers were related to tumor stage and size and clinical outcome. Results: Before treatment, SCC antigen was elevated (>1.9 μg/L) in 60% and CYFRA 21-1 (>2.2 μg/L) in 46% of patients. For all patients, disease-free survival (DFS) was better after combined treatment (67% vs. 43%, p<0.0005). For patients with elevated baseline SCC antigen, DFS was better after combination therapy (67% vs. 27%, p=0.001) which resulted more frequently in a normal SCC antigen (93% vs. 65%, p=0.004). In contrast, in those with a normal baseline CYFRA 21-1, combined therapy resulted in a better DFS (p=0.04). Patients who achieved a normal SCC antigen or CYFRA 21-1 after treatment had a better DFS (respectively 63 vs. 17% and 64 vs. 30%). Elevated SCC antigen posttreatment indicated residual tumor in 11/12 patients (92%), elevated CYFRA 21-1 in 7/10 patients (70%). Forty-seven patients had a tumor recurrence. At recurrence, SCC antigen was raised in 70% and CYFRA 21-1 in 69%. Conclusions: In patients with an elevated pretreatment SCC antigen, SCC antigen normalized more frequently with combined treatment and those patients had a better DFS. Elevated SCC antigen or CYFRA 21-1 levels after treatment completion indicated residual tumor in respectively 92% and 70%. The presence of elevated posttreatment levels of SCC antigen or CYFRA 21-1 indicates the need for additional

    Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers in the world with a close relation with some risk factor like, tobacco, alcohol consumption and more recently, with human papilloma virus infection. A review of the literature about actual prognosis and quality of life in HNSCC has been done analysing the results of surgical treatment and their impact on the quality of life of patients. Despite the elevated incidence of HNSCC, the survival rate has increased considerably over the last years thanks to the development of new surgical techniques, such as, microvascular reconstruction or transoral robotic surgery and the most accurate adjuvant radiochemotherapy. Even in bad prognosis cases, there are many options to take into account not only with curative expectation, even, keeping in mind the preservation of the quality of life of patients. Due to the improvement of the prognosis, the interest of surgeons has been focused on preserve the aesthetics, functional and psychosocial aspect of patients without a worsening of the main objective which is the curative result. Although prognosis of HNSCC has improved, further studies are necessary to understand the behaviour in every case and determine how the impact on the quality of life can be a useful tool to individualize the therapies.

  6. Radiotherapy alone or with chemotherapy in the treatment of small-cell carcinoma of the lung

    International Nuclear Information System (INIS)

    Findings at one year are given of a study comparing radiotherapy (Rt) with radiotherapy followed by 3-drug chemotherapy (RtC3) in the treatment of small-cell carcinoma of the lung of limited extent. Over the 12-month period there was a significantly increased survival for the RtC3 patients. The median survival for the Rt series was 25 weeks and for the RtC3 series 43 weeks. There was evidence of recurrence of the primary cancer in 32% of the Rt and 26% of the RtC3 patients who died. Distant metastases appeared earlier and were more frequent in the Rt series. At 12 months only 8% of the Rt but 26% of the RtC3 patients were alive and free of metastases. Adverse reactions occurred much more frequently in the RtC3 series; the most common being nausea and vomiting and the most serious being marrow depression. No important differences were found in general condition, physical activity or respiratory function. It is concluded that radiotherapy plus chemotherapy was superior to radiotherapy alone, although chemotherapy did not protect patients from recurrence of primary growth. (author)

    Background and Purpose: Extrapulmonary small cell carcinoma (EPSCC) is a rare disease, which has a slightly better prognosis than small cell lung cancer, but still dismal. Gynecologic small cell malignancies tend to show a better survival than similar histologies of other regions. However, of five reported cases of vulvar manifestation only one patient was disease-free at the time of publication with limited follow-up. Case Report: The authors describe a case of locally advanced small cell vulva carcinoma infiltrating the anal sphincter and urethra with spread to inguinal lymph nodes treated by radiochemotherapy and regional hyperthermia. After three cycles of carboplatin/etoposide, computed tomography and magnetic resonance imaging indicated only little regressive transformations but overall stable disease. Surgical options were excluded. Therefore, curative radiotherapy to a total dose of > 65 Gy to macroscopic tumor, chemotherapy with cisplatin weekly, and regional hyperthermia were performed. Acute severe toxicity was limited to skin reactions. Despite the disadvantageous situation with inguinal lymph node metastases and chemoresistance, the multimodal therapy yielded a 5-year disease-free survival. Conclusion: Thus, the trimodal regimen of radiochemotherapy plus regional hyperthermia offered a curative chance in spite of resistance to the standard chemotherapy for irresectable, locally advanced small cell carcinoma of the vulva. Therefore, this approach merits further evaluation for limited disease of EPSCC. (orig.)

    Full Text Available The aim of the study was to assess the expression and subcellular localization of visfatin in HCT-116 colorectal carcinoma cells after cytokinesis failure using Cytochalasin B (CytB and the mechanism of apoptosis of cells after CytB. We observed translocation of visfatin’s antigen in cytB treated colorectal carcinoma HCT-116 cells from cytosol to nucleus. Statistical and morphometric analysis revealed significantly higher area-related numerical density visfatin-bound nano-golds in the nuclei of cytB-treated HCT-116 cells compared to cytosol. Reverse relation to visfatin subcellular localization was observed in un-treated HCT-116 cells. The total amount of visfatin protein and visfatin mRNA level in HCT-116 cells was also decreased after CytB treatment. Additionally, CytB significantly decreased cell survival, increased levels of G2/M fractions, induced bi-nuclei formation as well as increased reactive oxygen species (ROS level in HCT-116 cells. CytB treatment showed cytotoxic effect that stem from oxidative stress and is connected with the changes in the cytoplasmic/nuclear amount of visfatin in HCT-116 cells.

    A total of 29 patients with advanced renal cell carcinoma entered a pilot study of combination therapy with interferon alpha (IFN-alpha) and interferon gamma (IFN-gamma). IFN-alpha (HLBI: 3 x 10(6) IU, BALL 1:5 x 10(6) IU, IFN-alpha-2a: 9 x 10(6) IU or IFN-alpha-2b: 6 x 10(6) IU) was given intramuscularly every day and IFN-gamma (IFN-gamma-1a: 3 x 10(6) JRU) was given intravenously by drip infusion 3 times a week (every 2-3 days). The treatment was continued for 3 months as the induction therapy, and then the tumor response was evaluated. Of the 22 evaluable patients, 4 achieved a partial response (PR), 10 showed no change (NC), and in 8 the disease had progressed (PD) during the therapy. Thus, the overall response rate was 18.2% [95% confidence interval (CI) 2.1-34.3%]. A favorable response tended to be obtained in patients with good performance status or small pulmonary metastases, or in those who had no prior therapy with IFN-alpha, who received this treatment immediately subsequent to radical nephrectomy, or who received IFN-gamma as much as possible according to this regimen. Toxicity was evaluated in 28 patients: fever, general fatigue, anorexia, leukocytopenia and impaired liver function were frequently noted, and 3 patients were withdrawn from the study because of such adverse effects. In patients who had a PR or NC, the same dosage of IFN-alpha was continued to be given intramuscularly 2-3 times a week (every 2-4 days) as the maintenance therapy.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7474618

  16. Preoperative radiotherapy in rectal signet-ring cell carcinoma - magnetic resonance imaging and treatment outcome

    International Nuclear Information System (INIS)

    Background. Signet-ring cell carcinoma (SRCC) is an uncommon tumor entity in rectal cancer, often considered to be resistant to non-surgical therapy. In locally advanced primary or recurrent rectal cancer, diagnostic information from magnetic resonance imaging (MRI) is considered superior in planning the optimal treatment strategy, which usually includes preoperative radiotherapy. The recognition of MRI features that correlate with the radiation response might ultimately be used to select patients for tailored treatment and, in addition, avoid potentially toxic therapy in non-responding patients. Material and methods. In a cohort of 120 rectal cancer patients who had received preoperative radiotherapy (50 Gy in 2 Gy fractions), six patients were noted to have SRCC tumor differentiation. Initial diagnostic MRI examination included assessment of local T- and N-stage and tumor morphology. Histological tumor response was subsequently assessed in the resected specimens, and postoperative follow-up data was compiled until disease recurrence. Results. Following the preoperative radiotherapy, two distinctly different histological responses - complete response (ypT0N0) or no response - were observed. Extensive mesorectal lymph node metastasis (N2 disease) at the pretreatment MRI examination was unambiguously associated with lack of response and rapid development of disseminated disease. Importantly, patients with complete response have been observed for 23-52 months postoperatively without evidence of recurrent disease. Discussion. Our review may suggest that patients with locally advanced growth of rectal SRCC, despite poorer outcome when compared to patients with conventional-type rectal adenocarcinoma, when presenting limited lymph node disease should be offered preoperative radiotherapy in a tentatively curative setting

    Neoadjuvant approaches in renal cell carcinoma are currently under investigation, following the demonstration of targeted therapy efficacy in the metastatic setting. It raises the issues of downsizing locally advanced or nonresectable tumor and offering organ-sparing surgery, safety and its potential role in early micrometastatic disease. Relevant studies of the neoadjuvant setting in renal cell carcinoma with targeted therapies were identified from the literature, clinical trial databases and conference abstracts. To date, a neoadjuvant approach appears feasible in terms of safety. Currently available drugs do not achieve major tumor downsizing with primary tumor diameters response rate of 10%. Neoadjuvants should only be considered in clinical trials or as a litmus test in locally advanced patients. PMID:23253222

    BACKGROUND In many centers, 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) is used to monitor treatment response after definitive (chemo)radiotherapy [(C)RT] for head and neck squamous cell carcinoma (HNSCC), but its usefulness remains somewhat controversial. We aimed at assessing the accuracy of FDG-PET/CT in detecting residual disease after (C)RT. METHOD All HNSCC patients with FDG-PET/CT performed to assess treatment response 10–18 weeks after definitive (C)RT at our institution during 2008–2010 were included. The patient charts were reviewed for FDG-PET/CT findings, histopathologic findings, and follow-up data. The median follow-up time for FDG-PET/CT negative patients was 26 months. RESULTS Eighty-eight eligible patients were identified. The stage distribution was as follows: I, n = 1; II, n = 15; III, n = 17; IV, n = 55. The negative predictive value, positive predictive value, specificity, sensitivity, and accuracy of FDG-PET/CT in detecting residual disease were 87%, 81%, 94%, 65%, and 85%, respectively. The corresponding specific figures for the primary tumor site were 91%, 71%, 94%, 59%, and 86% and for the neck 93%, 100%, 100%, 75%, and 94%, respectively. CONCLUSIONS In patients who have received definitive (C)RT for HNSCC, post-treatment FDG-PET/CT has good potential to guide clinical decision-making. Patients with negative scan can safely be followed up clinically only, while positive scan necessitates tissue biopsies or a neck dissection to rule out residual disease. PMID:25210484

  4. Expense and benefit of neoadjuvant treatment in squamous cell carcinoma of the esophagus

    International Nuclear Information System (INIS)

    The effectiveness of neoadjuvant treatment (NT) prior to resection of squamous cell carcinoma of the esophagus (SCCE) in terms of prolonged survival has not been proven by randomized trials. Facing considerable financial expenses and with concerns regarding the consumption of the patient's remaining survival time, this study aims to provide rationales for pretreating resection candidates. From March 1986 to March 1999, patients undergoing resection for SCCE were documented prospectively. Since 1989, NT was offered to patients with mainly upper and middle third T3 or T4 tumors or T2 N1 stage who were fit for esophagectomy. Until 1993, NT consisted of chemotherapy. Since that time chemoradiation has also been applied. The parameters for expense and benefit of NT are costs, pretreatment time required, postoperative morbidity and mortality, clinical and histopathological response, and actuarial survival. Two hundred and three patients were treated, 170 by surgery alone and 33 by NT + surgery. Postoperative morbidity and mortality were 52% to 30% and 12% to 6%, respectively (p = n.s.). The response to NT was detected in 23 patients (70%). In 11 instances (33%), the primary tumor lesion was histopathologically eradicated. Survival following NT + surgery was significantly prolonged in node-positive patients with a median survival of 12 months to 19 months (p = 0.0193). The average pretreatment time was 113 ± 43 days, and reimbursement for NT to the hospital amounted to Euro 9.834. NT did not increase morbidity and mortality. Expenses for pretreatment, particularly time and costs, are considerable. However, taking into account that the results are derived from a non-randomized study, patients with regionally advanced tumor stages seem to benefit, as seen by their prolonged survival

    Purpose: Penile squamous cell carcinoma (SCC) is a rare entity, with few published series on outcomes. We evaluated the stage distributions and outcomes for surgery and radiation therapy in a U.S. population database. Methods and Materials: Subjects with SCC of the penis were identified using the National Cancer Institute Surveillance, Epidemiology and End Results (SEER) Program database between 1988 and 2006. Descriptive statistics were performed, and cause-specific survival (CSS) was estimated using Kaplan-Meier analysis. Comparisons of treatment modalities were analyzed using multivariate Cox regression. Subjects were staged using American Joint Committee on Cancer, sixth edition, criteria. Results: There were 2458 subjects identified. The median age was 66.8 years (range, 17-102 years). Grade 2 disease was present in 94.5% of cases. T1, T2, T3, T4, and Tx disease was present in 64.8%, 17.1%, 9.5%, 2.1%, and 6.5% of cases, respectively. N0, N1, N2, N3, and Nx disease was noted in 61.6%, 6.9%, 4.0%, 3.7%, and 23.8% of cases, respectively. M1 disease was noted in 2.5% of subjects. Individuals of white ethnicity accounted for 85.1% of cases. Lymphadenectomy was performed in 16.7% of cases. The CSS for all patients at 5 and 10 years was 80.8% and 78.6%. By multivariable analysis grades 2 and 3 disease, T3 stage, and positive lymph nodes were adverse prognostic factors for CSS. Conclusion: SCC of the penis often presents as early-stage T1, N0, M0, grade 1, or grade 2 disease. The majority of patients identified were treated with surgery, and only a small fraction of patients received radiation therapy alone or as adjuvant therapy.

    Purpose/Objective(s) We examined practice patterns using the National Cancer Database (NCDB) to determine risk factors for prolonged diagnosis to treatment interval (DTI) and survival outcomes in patients receiving chemoradiation for oropharyngeal squamous cell carcinoma (OPSCC). Methods and Materials We identified 6,606 NCDB patients with Stage III-IV OPSCC receiving chemoradiation from 2003-2006. We determined risk factors for prolonged DTI (>30 days) using univariate and multivariable logistic regression models. We examined overall survival (OS) using Kaplan Meier and multivariable Cox proportional hazards models. Results 3,586 (54.3%) patients had prolonged DTI. Race, IMRT, insurance status, and high volume facilities were significant risk factors for prolonged DTI. Patients with prolonged DTI had inferior OS compared to DTI ≤ 30 days (Hazard Ratio (HR)=1.12, 95% CI 1.04-1.20, p=0.005). For every week increase in DTI there was a 2.2% (95% CI 1.1%-3.3%, pacademic, or high-volume facilities were more likely to experience prolonged DTI (High vs. Low volume: 61.5% vs. 51.8%, adjusted OR 1.38, 95% CI 1.21-1.58; Academic vs. Community: 59.5% vs. 50.6%, adjusted OR 1.26, 95% CI 1.13-1.42; non-IMRT vs. IMRT: 53.4% vs. 56.5%; adjusted OR 1.17, 95% CI 1.04-1.31). Conclusions Our results suggest that prolonged DTI has a significant impact on survival outcomes. We observed disparities in DTI by socioeconomic factors. However, facility level factors such as academic affiliation, high volume, and IMRT also increased risk of DTI. These findings should be considered in developing efficient pathways to mitigate adverse effects of prolonged DTI. PMID:27086482

  10. Combined-modality treatment for advanced oral tongue squamous cell carcinoma

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to investigate prognostic factors in advanced-stage oral tongue cancer treated with postoperative adjuvant therapy and to identify indications for adjuvant concomitant chemoradiotherapy (CCRT). Methods and Materials: We retrospectively reviewed the records of 201 patients with advanced squamous cell carcinoma of the oral tongue managed between January 1995 and November 2002. All had undergone wide excision and neck dissection plus adjuvant radiotherapy or CCRT. Based on postoperative staging, 123 (61.2%) patients had Stage IV and 78 (38.8%) had Stage III disease. All patients were followed for at least 18 months after completion of radiotherapy or until death. The median follow-up was 40.4 months for surviving patients. The median dose of radiotherapy was 64.8 Gy (range, 58.8-72.8 Gy). Cisplatin-based regimens were used for chemotherapy. Results: The 3-year overall survival (OS) and recurrence-free survival (RFS) rates were 48% and 50.8%, respectively. Stage, multiple nodal metastases, differentiation, and extracapsular spread (ECS) significantly affected disease-specific survival on univariate analysis. On multivariate analysis, multiple nodal metastases, differentiation, ECS, and CCRT were independent prognostic factors. If ECS was present, only CCRT significantly improved survival (3-year RFS with ECS and with CCRT = 48.2% vs. without CCRT = 15%, p = 0.038). In the presence of other poor prognostic factors, results of the two treatment strategies did not significantly differ. Conclusions: Based on this study, ECS appears to be an absolute indication for adjuvant CCRT. CCRT can not be shown to be statistically better than radiotherapy alone in this retrospective series when ECS is not present

  11. Treatment of Oral Cavity Squamous Cell Carcinoma With Adjuvant or Definitive Intensity-Modulated Radiation Therapy

    International Nuclear Information System (INIS)

    Purpose: The optimal management of oral cavity squamous cell carcinoma (OCSCC) typically involves surgical resection followed by adjuvant radiotherapy or chemoradiotherapy (CRT) in the setting of adverse pathologic features. Intensity-modulated radiation therapy (IMRT) is frequently used to treat oral cavity cancers, but published IMRT outcomes specific to this disease site are sparse. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for OCSCC. Methods and Materials: Retrospective study of all patients treated at Dana-Farber Cancer Institute for OCSCC with adjuvant or definitive IMRT between August 2004 and December 2009. The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1–3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

  13. Squamous cell carcinoma of the anal canal: treatment by external beam irradiation

    International Nuclear Information System (INIS)

    External beam radiation therapy alone or in combination with curietherapy is the recommended treatment for anal canal carcinoma in some countries. In others, surgery is the sole accepted treatment. The results for 64 patients treated by external radiotherapy alone show excellent survival for stage T1T2 tumors but results are poor for large tumors (stage T4). Complications follow radiotherapy more frequently in those with stage T3 and T4 tumors. The analysis of local recurrences, complications and survival shows that radiation therapy may be sufficient treatment for stage T1 and T2 and for some stage T3 tumors. The importance of anal sphincter involvement and the poor quality of life for patients who are cured but develop complications, shows the need for combined treatment with surgery and perhaps with chemotherapy. For small tumors the results obtained by external radiotherapy alone are comparable with those obtained by external radiotherapy and curietherapy in terms of survival and complications. (Auth.)

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Our knowledge of renal cell carcinoma (RCC) is rapidly expanding. For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC. PMID:24364021

    Directory of Open Access Journals (Sweden)

    Jerome Azike

    2009-07-01

    Full Text Available Squamous cell carcinoma of the scrotum is a tumor that is of interest for clinical and historical reasons. It was the first cancer linked to occupational exposure when, in 1775, Perivall Pott described it in chimney sweeps in England. Other occupations that had a preponderance of the disease included people who worked with the distillates of coal and men exposed to mineral oil. Currently, the disease is very rare and most cases are thought to result from poor hygiene and chronic irritation. Surgery with a negative resection margin offers the best hope of cure as adjunctive therapy has not proved useful. Prognosis correlates with the extent of nodal involvement.

  18. Squamous cell carcinoma of the oropharynx--an analysis of treatment results in 289 consecutive patients

    International Nuclear Information System (INIS)

    In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment

    Merkel cell carcinoma (MCC) is a rare but aggressive cutaneous tumor with a predilection for the head and neck of elderly Caucasian patients. Although much less common than melanoma, MCC has higher rates of sentinel lymph node involvement, local and regional recurrences, and mortality. The majority of MCC cases have been linked to the relatively newly discovered Merkel cell polyomavirus, which is a ubiquitous constituent of the skin flora. Recent discoveries regarding viral integration and carcinogenesis and the immunologic features of MCC have expanded the understanding of MCC. These discoveries have led to the development and application of emerging therapies such as somatostatin analogs, immune checkpoint inhibition, adoptive cell therapy, and other exciting possibilities for targeted therapy.

    External auditory canal (EAC) carcinomas are relatively rare conditions lack on established treatment strategy. We analyzed a treatment modalities and outcome in 32 cases of EAC squamous cell carcinoma treated between 1980 and 2008. Subjects-17 men and 15 women ranging from 33 to 92 years old (average: 66) were divided by Arriaga's tumor staging into 12 T1, 5 T2, 6 T3, and 9 T4. Survival was calculated by the Kaplan-Meier method. Disease-specific 5-year survival was 100% for T1, T2, 44% for T3, and 33% for T4. In contrast to 100% 5-year survival for T1+T2 cancer, the 5-year survival for T3+T4 cancer was 37% with high recurrence due to positive surgical margins. The first 22 years of the 29 years surveyed, we performed surgery mainly, and irradiation or chemotherapy was selected for early disease or cases with positive surgical margins as postoperative therapy. During the 22-years, 5-year survival with T3+T4 cancer was 20%. After we started superselective intra-arterial (IA) rapid infusion chemotherapy combined with radiotherapy in 2003, we achieved negative surgical margins for advanced disease, and 5-year survival for T3+T4 cancer rise to 80%.

  3. A planning study investigating dual-gated volumetric arc stereotactic treatment of primary renal cell carcinoma

    International Nuclear Information System (INIS)

    This is a planning study investigating the dosimetric advantages of gated volumetric-modulated arc therapy (VMAT) to the end-exhale and end-inhale breathing phases for patients undergoing stereotactic treatment of primary renal cell carcinoma. VMAT plans were developed from the end-inhale (VMATinh) and the end-exhale (VMATexh) phases of the breathing cycle as well as a VMAT plan and 3-dimensional conformal radiation therapy plan based on an internal target volume (ITV) (VMATitv). An additional VMAT plan was created by giving the respective gated VMAT plan a 50% weighting and summing the inhale and exhale plans together to create a summed gated plan. Dose to organs at risk (OARs) as well as comparison of intermediate and low-dose conformity was evaluated. There was no difference in the volume of healthy tissue receiving the prescribed dose for the planned target volume (PTV) (CI100%) for all the VMAT plans; however, the mean volume of healthy tissue receiving 50% of the prescribed dose for the PTV (CI50%) values were 4.7 (± 0.2), 4.6 (± 0.2), and 4.7 (± 0.6) for the VMATitv, VMATinh, and VMATexh plans, respectively. The VMAT plans based on the exhale and inhale breathing phases showed a 4.8% and 2.4% reduction in dose to 30 cm3 of the small bowel, respectively, compared with that of the ITV-based VMAT plan. The summed gated VMAT plans showed a 6.2% reduction in dose to 30 cm3 of the small bowel compared with that of the VMAT plans based on the ITV. Additionally, when compared with the inhale and the exhale VMAT plans, a 4% and 1.5%, respectively, reduction was observed. Gating VMAT was able to reduce the amount of prescribed, intermediate, and integral dose to healthy tissue when compared with VMAT plans based on an ITV. When summing the inhale and exhale plans together, dose to healthy tissue and OARs was optimized. However, gating VMAT plans would take longer to treat and is a factor that needs to be considered

    Full Text Available Introduction. Penile cancer is a rare malignancy often treated with neoadjuvant chemotherapy followed by surgery. However, the utility of neoadjuvant chemoradiation, particularly when the tumor is resistant to chemotherapy alone, has not been established. In this study, we report a case of pT3cN3M0 penile squamous cell carcinoma with progression of nodal disease on chemotherapy, which was cured with use of neoadjuvant concurrent chemoradiation. Case Report. A 65-year-old male presented with a fixed left inguinal lymph node with associated firmness of the penile glans. Biopsies of both sites revealed evidence of squamous cell carcinoma. The patient underwent partial penectomy for the primary lesion and began neoadjuvant chemotherapy to reduce the size of the unresectable left inguinal node. However, he displayed disease progression in the left inguinal node. As such, we attempted concurrent chemoradiation therapy with regression of his nodal disease. The patient was able to undergo left inguinal node dissection and has no evidence of disease 18 months since his initial surgery. Conclusion. The use of neoadjuvant chemoradiation for bulky cN2-3 disease seems appropriate in the setting of progressive disease. Further studies are necessary to assess the utility of concurrent chemoradiation both in the neoadjuvant and salvage setting.

    To describe the clinical characteristics, treatment patterns and outcomes in advanced small cell bladder cancer (aSCBC) patients and compare to those with urothelial carcinoma (UC). Individuals in the National Cancer Data Base with a diagnosis of either nodal (TxN+M0) or distant metastatic (TxNxM1) disease were identified from 1998 to 2010. We assessed the relationships between stage, treatment modalities and survival in the aSCBC cohort and compared these to UC patients. In the 960 patient aSCBC cohort (62% M1), 50% received palliative therapy alone, 68% in M1 versus 21% in M0 groups (P carcinoma patients (n = 27,796, 45% M1) lived longer compared to aSCBC patients in the N+M0 group (17.3 months vs. 13.0 months, P = 0.0007). There were not clinically significant differences in OS between UC and aSCBC patients in the M1 group. Advanced SCBC is a rare disease with a poor survival and palliative therapy is common, especially in M1 patients. In comparison to UC, the outcomes for aSCBC patients are worse in those with lymph node only involvement but similar in those with distant disease. PMID:26679712

  7. Concurrent radiochemotherapy in locally-regionally advanced oropharyngeal squamous cell carcinoma: analysis of treatment results and prognostic factors

    International Nuclear Information System (INIS)

    Concurrent radiochemotherapy is a recommended treatment option for patients with locally advanced squamous cell head and neck carcinomas with recent data showing the most significant absolute overall and event-free survival benefit achieved in patients with oropharyngeal tumours. The aim of this study was to analyse the results of three-dimensional conformal radiotherapy given with concomitant weekly cisplatin in patients with advanced oropharyngeal carcinoma and to identify prognostic factors influencing outcomes of this patients category. Sixty-five patients with stage III or IV squamous cell carcinoma of the oropharynx who underwent concurrent radiochemotherapy between January 2005 and December 2010 were retrospectively analyzed. All patients received radiotherapy to 70 Gy/35 fractions/2 Gy per fraction/5 fractions per week. Concurrent chemotherapy consisted of weekly cisplatin (30 mg/m2) started at the first day of radiotherapy. Median age was 57 years (range, 36 to 69 years) and 59 (90.8%) patients were male. Complete composite response was achieved in 47 patients (72.3%). Local and/or regional recurrence was the most frequent treatment failure present in 19 out of 25 patients (76.0%). At a median follow-up of 14 months (range, 5 to 72 months), 2-year local relapse-free, regional relapse-free, locoregional relapse-free, disease-free, and overall survival rates were 48.8%, 57.8%, 41.7%, 33.2% and 49.7%, respectively. On multivariate analysis the only significant factor for inferior regional relapse-free survival was the advanced N stage (p = 0.048). Higher overall stage was independent prognostic factor for poorer local relapse-free survival, locoregional relapse-free survival and disease-free survival (p = 0.022, p = 0.003 and p = 0.003, respectively). Pre-treatment haemoglobin concentration was an independent prognostic factor for local relapse-free survival, regional relapse-free survival, locoregional relapse-free survival, disease-free survival, and

  9. Low Doses of Gamma Rays Reduce the Sensitivity of Cervical Carcinoma Cells to Subsequent Treatment with Cisplatin

    International Nuclear Information System (INIS)

    One of the major challenges of modern genetics is to apply recent advances in mutation research to improve the accuracy of the estimates of the genetic risk for humans. Because of the important implications for radiation protection, biological effects of low-dose radiation have been a focus of research in recent years. Previously we have found that human cervical carcinoma HeLa cells irradiated repeatedly with low doses of gamma rays (HeLa1500 cells) became resistant to cisplatin. In this study we examine whether this effect was caused by inhibition of apoptosis. In HeLa and HeLa1500 cells we determined the induction of apoptosis following the treatment with cisplatin (i) by counting apoptotic cells with characteristic morphological changes, (ii) by analysing the expression of apoptotic genes involved in cytochrome c/Apaf-1/caspase-9 and in Fas/FasL pathways by Western blot method, and (iii) by estimating the activities of caspases by commercial caspase detection kits. Our results show that low doses of gamma rays induced alterations in human cervical carcinoma cells that were reflected in inhibition of p53-independent cisplatin-induced apoptosis due to reduced activity of caspase 3.

    Renal cell carcinoma (RCC) is the eighth most common malignancy in adults in the United States. More than 50% of individuals present with metastatic disease and conventional chemotherapeutic strategies have been associated with poor response rates. Immunotherapy with Interleukin (IL)-2, however, induces durable remission, achieving >10 year recurrence free survival in 5-10% of patients with advanced RCC. First described as a T cell growth factor, IL-2 has a wide spectrum of effects in the immune system. Some of the possible mechanisms by which IL-2 carries out its anticancer effects include the augmentation of cytotoxic immune cell functions and reversal of T cell anergy, enabling delivery of immune cells and possibly serum components into tumor. IL-2 indirectly limits tumor escape mechanisms such as defective tumor cell expression of Class I or Class II molecules or expansion of regulatory T cells. Indirect effects on the tumor microenvironment are also likely and associated with rather dramatic T cell infiltration during the global delayed type hypersensitivity response that is associated with systemic IL-2 administration. The IL-2 signaling pathway, its effects on immune cells, and its role in various independent mechanisms of tumor surveillance likely play a role but little substantive data defining a clear phenotype or genotype of IL-2 responders distinguishing them from nonresponders has emerged in the last 25 years since IL-2 therapy was initiated. At best, we can only speculate that the disturbed homeostatic host/tumor interaction is reset in a small subset of patients allowing an antitumor response to recover or ensue. PMID:19148593

    As extra-pulmonary small cell carcinoma (EPSCC) is a rare entity of tumors, the available treatment recommendations are mainly based on retrospective analyses and deduction from treatment of small cell lung cancer. The aim of this study was to provide a detailed analysis concerning prognostic factors and treatment modalities. A total of 20 patients with limited disease (LD) of EPSCC treated at our institution from 1999-2009 were retrospectively analyzed. Data were gathered from chart review. Localization, lymph node involvement, as well as local and systemic treatment were documented and their impact on pattern of failure and survival times statistically evaluated. With a median follow-up of 21 months, the estimated median overall- and disease-free survival were 59 and 25 months, respectively. Local control was excellent with 100% at 2 years. Nodal involvement was observed in 74% (n = 14/19) of evaluable patients. However, outcome was not altered by this parameter. Local treatment consisted of surgery in 10 cases, radiotherapy in 7 cases, and a combination of both in 3 cases. Only 3 patients (15%) developed hematogenous central nervous system metastases, while none of the patients received prophylactic cranial irradiation. Nodal involvement did not worsen prognosis. Local control was excellent irrespective of local treatment modality and the leading cause of failure was distant metastasis. Therefore, systemic treatment should not be omitted. Prophylactic cranial irradiation might be dispensable but discussed for head and neck malignancies.

  13. Squamous cell carcinoma of the maxillary sinus and the oral part of the upper jaw. Comparison of treatment results

    International Nuclear Information System (INIS)

    The treatment results were compared in 77 patients with maxillary sinus squamous cell carcinoma (MC) and 53 patients with squamous cell carcinoma arising from the oral part of the upper law (OC). Both sets of patients received radiotherapy alone, or radiotherapy combined with surgery and/or chemotherapy. Computerized tomography was useful for the definition of the treatment volume. Intraarterial chemotherapy was given in 89 of 130 patients and in these patients the total radiation dose was reduced by about 10 Gy. No difference was found in the 5-year survival rate between the MC (65%) and the OC (66%) groups. The cumulative incidence of local failure was higher in MC (36%) than in OC (26%), whereas the ultimate incidence of neck node metastasis was higher in OC (43%) than in MC patients (18%). Half of the inoperable patients (9/18) were older than 80 years and had contraindications to anaesthesia and major surgery. The local recurrence rate was high in the inoperable MC patients (6/8). Contralateral simus cancers occurred in 4 patients in the MC group. (orig.)

  16. Combined-modality treatment in advanced oral squamous cell carcinoma. Primary surgery followed by adjuvant concomitant radiochemotherapy

    International Nuclear Information System (INIS)

    The efficacy of adjuvant radiochemotherapy (RCT) in patients with advanced stage head and neck carcinoma has been proven in prospective randomized trials. However, these trials focused on different head and neck sites. Specific analyses for treatment effects in squamous cell carcinoma of the oral cavity (OSCC) are missing. We evaluated our experiences with adjuvant concomitant RCT in advanced OSCC to compare the results with other treatment schemes using adjuvant RCT. A total of 183 patients with OSCC of UICC stages II-IVb were reviewed retrospectively. All patients were treated with radical surgery followed by adjuvant, conventional fractionated concomitant RCT using carboplatin. Overall survival was plotted by Kaplan-Meier analysis. Prognostic factors were identified through univariate and multivariate analysis. Univariate analysis showed a significant impact of T, N, and UICC stage, histopathologic grading, surgical margins, extracapsular spread (ECS), and lymphangiosis carcinomatosa on overall survival (Table 3). Patients with stage IVa had a higher 5-year overall survival rate (42.8%) than patients with stage IVb (25.0%) (Figure 1). The differences were significant in multivariate analysis (p = 0.033) (Table 4). Adjuvant concomitant RCT is an effective treatment in patients with advanced stage OSCC. However, it remains unclear, which patients should be treated with adjuvant RCT. For patients with stage IVb, adjuvant RCT yields poor results. Prospective randomized trials are needed to confirm which patients should be treated with adjuvant RCT. (orig.)

  19. Papillary renal cell carcinoma

    International Nuclear Information System (INIS)

    Between 1976 and 1987, 395 patients with kidney tumors were studied with radiological techniques and sonography. In 37 cases (9.4%) histopathology diagnosed pure papillary renal cell carcinoma. Analyzing the radiographic patterns of these neoplasms, the authors observed constantly diminished vascularity (100%) frequent calcifications (35.1%) and necrotic areas (51.3%). Such X-ray features are not specific: nevertheless, their coexistence is strongly suggestive of papillary renal cell cancer. No consistent US pattern was found; however, necrotic areas were easily demonstrated in most cases. It must be stressed how patients with papillary carcinoma experienced a longer post-operative survival; it has not yet been established whether such favorable behavior is due to low biological aggressiveness or to earlier diagnosis

    Full Text Available Due to the rarity of Merkel cell carcinoma (MCC, prospective clinical trials have not been practical. This study aimed to identify biomarkers with prognostic significance. While sixty-two patients were identified who were treated for MCC at our institution, only seventeen patients had adequate formalin-fixed paraffin-embedded archival tissue and followup to be included in the study. Patients were stratified into good, moderate, or poor prognosis. Laser capture microdissection was used to isolate tumor cells for subsequent RNA isolation and gene expression analysis with Affymetrix GeneChip Human Exon 1.0 ST arrays. Among the 191 genes demonstrating significant differential expression between prognostic groups, keratin 20 and neurofilament protein have previously been identified in studies of MCC and were significantly upregulated in tumors from patients with a poor prognosis. Immunohistochemistry further established that keratin 20 was overexpressed in the poor prognosis tumors. In addition, novel genes of interest such as phospholipase A2 group X, kinesin family member 3A, tumor protein D52, mucin 1, and KIT were upregulated in specimens from patients with poor prognosis. Our pilot study identified several gene expression differences which could be used in the future as prognostic biomarkers in MCC patients.

    Topical photodynamic therapy (PDT) is a promising alternative for malignant skin diseases such as basal-cell carcinoma (BCC), due to its simplicity, enhanced patient compliance, and localization of the residual photosensitivity to the site of application. However, insufficient photosensitizer penetration into the skin is the major issue of concern with topical PDT. Therefore, the aim of the present study was to enable penetration of photosensitizer to the different strata of the skin using a lipid nanocarrier system. We have attempted to develop a nanostructured lipid carrier (NLC) for the topical delivery of second-generation photosensitizer, 5-amino levulinic acid (5-ALA), whose hydrophilicity and charge characteristic limit its percutaneous absorption. The microemulsion technique was used for preparing 5-ALA-loaded NLC. The mean particle size, polydispersity index, and entrapment efficiency of the optimized NLC of 5-ALA were found to be 185.2 ± 1.20, 0.156 ± 0.02, and 76.8 ± 2.58%, respectively. The results of in vitro release and in vitro skin permeation studies showed controlled drug release and enhanced penetration into the skin, respectively. Confocal laser scanning microscopy and cell line studies respectively demonstrated that encapsulation of 5-ALA in NLC enhanced its ability to reach deeper skin layers and consequently, increased cytotoxicity.

    The authors report 1,166 tumors of the eyelids that were treated by single or fractionated exposures to doses of 20-60 Gy. The five year tumor control rate was 95% for basal cell and 93.3% for squamous cell carcinoma. Irradiation was equally successful in primary cases and in those recurrent following surgery. The cosmetic and functional results were generally excellent and readily accepted by most patients. The overall complication rate was 9.6% with fewer than one-half rated as serious; these problems mainly occurred with large tumors that had destroyed normal tissues. In only 14 (1.2%) patients was death related to the tumor. Approximately one-half of the patients received a dose of 35 Gy in five daily fractions, one-quarter, 20 to 22.5 Gy in a single exposure and the others with larger tumors 42.5-60 Gy in 10 to 30 exposures in two to six weeks

    Oncological research and cancer treatment are more common in human medicine than in veterinary medicine. Nevertheless the latest decennium chemotherapy, radiotherapy and surgery also figure largely in the cancer treatment of pets. For this matter, the present study tried to explore the applicability of Photodynamic Therapy (PDT) as a proper and advantageous alternative for those treatments. PDT using topical 5-aminolaevulinic acid (5-ALA) cream was applied on superficial squamous cell carcinomas (SCC) at the nasal planum of two cats. Five hours after the cream was applied, the photosensitizing agent was removed and the sensitized area was irradiated with a red Light Emitting Diode (LED) contrivance with a wavelength of 660 nm. LED irradiation was administrated during 20 minutes, at a power output of 80 mW, with an energy density outcome of 38 J/cm2. The day after ths irradiation, the tumor area became erythematous and somewhat oedematous. After two days a scab occurred. Long-term post treatment observation showed complete removal of the malign cells related with regain of normal skin structure after three weeks. Follow-up period of one year for the first case and of two months for the second case revealed no recurrence. These promising results indicate that PDT is a possible alternative method to treat superficial skin tumors. Especially when taking into account that chemotherapy and radiotherapy are time-consuming treatments and that surgery (complete removal of the nasal planum) is not an esthetical solution.

    Full Text Available Photodynamic therapy (PDT is a clinically approved treatment that causes a selective cytotoxic effect in cancer cells. In addition to the production of singlet oxygen and reactive oxygen species, PDT can induce the release of nitric oxide (NO by up-regulating nitric oxide synthases (NOS. Since non-optimal PDT often causes tumor recurrence, understanding of the molecular pathways involved in the photoprocess is a challenging task for scientists. The present study has examined the response of the PC3 human metastatic prostate cancer cell line, following repeated low-dose pheophorbide a treatments, mimicking non-optimal PDT treatment. The analysis was focused on the NF-kB/YY1/RKIP circuitry as it is (i dysregulated in cancer cells (ii modulated by NO and (iii correlated with the epithelial to mesenchymal transition (EMT. We hypothesized that a repeated treatment of non-optimal PDT induces low levels of NO that lead to cell growth and EMT via regulation of the above circuitry. The expressions of gene products involved in the circuitry and in EMT were analyzed by western blot. The findings demonstrate the cytoprotective role of NO following non-optimal PDT treatments that was corroborated by the use of l-NAME, an inhibitor of NOS.

    Non-invasive real time methods for characterizing biomolecular events that contribute towards apoptotic kinetics would be of significant importance in the field of cancer biology. Effective drug-induced apoptosis is an important factor for establishing the relationship between cancer genetics and treatment sensitivity. The objective of this study was to develop a non-invasive technique to characterize cancer cells that are undergoing drug-induced apoptosis. We used dielectrophoresis to determine apoptotic cells as early as 2h post drug treatment as compared to 24h with standard flow cytometry method using non-small cell lung cancer (NSCLC) adenocarcinoma cell line (HCC1833) as a study model. Our studies have shown significant differences in apoptotic cells by chromatin condensation, formation of apoptotic bodies and exposure of phosphatidylserine (PS) on the extracellular surface when the cells where treated with a potent Bcl-2 family inhibitor drug (ABT-263). Time lapse dielectrophoretic studies were performed over 24h period after exposure to ABT-263 at clinically relevant concentrations. The dielectrophoretic studies were compared to Annexin-V FITC flow assay for the detection of PS in mid-stage apoptosis using flow cytometry. As a result of physical and biochemical changes, inherent dielectric properties of cells undergoing varying stages of apoptosis showed amplified changes in their cytoplasmic and membrane capacitance. In addition, zeta potential of these fixed isolated cells was measured to obtain direct correlation to biomolecular events. PMID:27262539

    Squamous cell carcinoma of the anal canal is rather rare and amounts to 3.5% of all rectal neoplasms. Though it has a clear-cut clinical picture, 29.5% of patients admitted for specialized treatment suffer from stage 4 due to inadequate diagnosis. Surgery is the most effective method of management of squamous cell carcinoma of the anal canal. Radiation therapy may be an adjuvant procedure to surgery

    Summary Background Common skin tumors like basal- and squamous-cell carcinoma present a serious problem in modern medicine. Exposure to ultraviolet solar radiation is the main cause of these lesions. Since application of Aldara® and PDT separately is well documented, we decided to use both methods together. The aim of our study was to evaluate the effectiveness of local photodynamic therapy supplemented with topical application of Aldara® in basal-cell carcinoma. Material/Methods Thirty-four ...

  13. Radiation treatment of glottic squamous cell carcinoma, Stage I and II: analysis of factors affecting prognosis

    International Nuclear Information System (INIS)

    Purpose: At least in some European Countries, there is still considerable controversy regarding the choice between surgery and radiotherapy for the treatment of patients with early laryngeal-glottic carcinoma. Methods and Materials: Two hundred and forty-six patients with laryngeal-glottic neoplasms, Stage I-II, were treated with radical radiotherapy. Before radiotherapy the patients were evaluated to determine the surgical procedure of choice. Either 66-68.4 Gy (33-38 fractions) or 63-65 Gy (28-29 fractions) of radiation therapy (RT) were administered. The overall disease free survival was determined for each subgroup of patients. Univariate and multivariate analyses were performed to determine significant prognostic variables. Results: Five- and 10-year overall survival rates were 83 and 72%, respectively. At a median follow-up of 6 years 204 patients are alive and disease free. No patient developed distant metastases. One patient died of a large local recurrence, 38 patients died of causes unrelated to their tumor, and 3 patients were lost to follow-up. The multivariate analysis confirmed that performance status (PS), macroscopic presentation of the lesion, and persistence of dysphonia after radiotherapy are significant prognostic factors. Conclusions: According to the multivariate analysis, the patients with PS >80 and with exophytic lesions are eligible for radical RT. The surgical procedure proposed for each patient was not found to be an independent prognostic factor

    A total of 12 patients with advanced renal cell carcinoma received interferon alpha (3 million units intramuscularly 6 times weekly) and OK-432 (5 KE (Klinische Einheit) intramuscularly twice weekly). Metastatic lesions appeared before operation in six patients and after operation in six patients. Among them 5 patients had received interferon therapy and this combination therapy was started after the judgment of progressive disease for interferon therapy. Eleven pulmonary and 5 bone metastases were evaluable. The median duration of the combination therapy was 89.3 weeks. There were 4 partial responses and no complete responses among the 12 patients, giving a response rate of 33.3%. The median duration of response was 25 months, with a range of 6 to 54 months. Responses were seen predominantly in patients in whom metastases appeared after operation (3 of 4 responders). However, regarding the individual organs, two complete and 2 partial responses were observed among 11 pulmonary metastases and 2 partial responses among 5 bone metastases. The survival period after discovery of the metastasis was 10 to 67 months and the 5-year survival rate was 70.5%. Almost all patients had fever and induration at the injection site. Other side effects included leukopenia, anorexia, and depression. This combination therapy is thought to be effective against bone or other organs metastasis resistant to interferon alone.

    1982-04-01

    Thirty-four previously untreated patients with histologically proven small cell carcinoma of the lung were treated with a combined modality therapy program that incorporated VP16-213, an epipodophyllotoxin derivative, into the chemotherapy regimen. Initial therapy for two cycles was with V-CAM, VP16-213, cyclophosphamide, doxorubicin and methotrexate. Following two cycles of V-CAM each patient received radiation therapy consisting of 4000 rads to the primary site, both hila and the mediastinum, as well as 2000 rads as prophylaxis to the whole brain. After a one-week rest period the patients received monthly cycles of V-CAM until death. Of 10 patients with stage IIIM0 disease, 7 had a complete response (CR), 1 a partial response (PR) and 2 had progressive disease. The median survival was still not reached by approximately 18 months. Of 24 patients with supraclavicular and/or metastatic disease there were only 5 patients with a CR, 11 with a PR and 8 with progressive disease. Their median survival was approximately 9 months. The 70% overall response rate and 9.3-month median survival of the entire group are essentially the same results as those in previously reported studies. There appears to be no additional benefit when VP16-213 is incorporated into our combined modality program. PMID:6288390

  16. Combined chemotherapy in the treatment of limited small cell lung carcinoma

    International Nuclear Information System (INIS)

    Between 1978 and 1983, 34 patients (32 evaluable) suffering from limited small cell lung carcinoma (SCLC-L) were treated following the protocol polychemotherapy (CAV) plus thoracic telecobaltotherapy and precaucional cranial irradiation (30 Gy in 2 weeks). Minimum follow-up was 30 months. After induction chemotherapy there was complete remission (CR) in 20% of cases whereas at the end of induction chemo-radiotherapy there was complete remission (CR) in 44% (p<0.05) of cases. Median duration of the responds was 12 months. Total median survival is 15 months, median NED survival 32 months (6-90 months). Seven out of 14 CR patients received consolidated thoracic radiotherapy (Rt); 6 of these survived disease-free for over 2 years. No salvage therapy carried out has proved useful. Only in one patient (3%) brain metastasis occurred. Iatric toxicity was also kept within limits of brain level. The role Rt plays in increasing the CR percentage, in drastically diminuishing the incidence of brain metastasis, in improving the quality of life by increasing the disease-free interval must be emphasized. Finally it should be noted that only CR patients have the possibility to become long survivors

    Full Text Available Background. Experience with combination treatment, i.e. systemic therapy in combination with palliative surgery, in the treatment of metastatic kidney cancer is very rarely described in world literature.Objective: to evaluate the efficiency of combination treatment in combination with palliative cytoreductive surgery and targeted therapy and to define optimal indications for combination treatment.Subjects and methods. Data on 47 patients with metastatic renal cell carcinoma (mRCC who received systemic (targeted therapy in combination or after incomplete cytoreduction (iCR were analyzed in this retrospective study. The proportion of men and women was 72.3 % and 27.7 %, respectively; their ratio was 2.6:1. All the patients (100% underwent surgical treatment as nephrectomy or kidney resection for primary tumor. In the patients who had received radical treatment in different periods, the median relapse-free survival was 25.3 (0-187 months; the mean follow-up duration in the study was 33.2 (27.4–39.0 months. Out of the histological characteristics of a primary tumor, its Fuhrman grade was studied. Prior to initiation of mRCC therapy, Memorial Sloan Kettering Cancer Center (MSKCC prognosis groups were assessed; the patients were divided into good (n = 9 (19.1 %, interim (n = 28 (59.6 %, and bad (n = 10 (21.3 % prognosis groups. Their total somatic status was separately rated using the ECOG scale: 0, (n = 10 (21.3%, 1 (n = 24 (51.1 %, and 2, (n = 13 (27.6 %. The sites of metastases were as follows: the lung (n = 29, bones (n = 18, adrenals (n = 11, recurrence in the removed kidney bed (n = 10, and liver (n = 10. Multiple organ involvements were detected in 22 (46.8 % patients. There were more than 5 metastases in one organ in 18 (40.0 % patients and only 15 (33.3 % were found to have a single focus in one organ. Whether iCR might be used as a separate line treatment was studied.

  18. Combined treatment of breast carcinoma cells in vitro by photodynamic therapy and ionizing radiation

    International Nuclear Information System (INIS)

    The toxicity of the 2 photosensitizers zincphthalocyanine (ZnPC) and meso-tetra-hydroxyphenylchlorine (m-THPC) as well as the biological effect of the combination of sensitizers with laser light were tested in vitro by means of a colony forming assay. In addition, the influence on the photodynamic reaction of a previous exposure of the tumor cells to ionizing radiation has been tested. For both sensitizers doses of 5 μg per milliliter of culture medium showed low toxicity, i.e. the survival of the treated cells exceeded 90%. For laser treatments the dose permitting 90% survival was determined to be around 10 J/cm2. With these doses, the combined application of photosensitizers and laser light proved to be very effective and resulted in a nearly complete reduction of survival. As expected, irradiation of the cells with doses of 1 and 2 Gy of X-rays reduced the survival to 66 and 47%, respectively, compared to untreated controls. Cells surviving such treatment showed no changes either in the response to treatments with photosensitizers or to combined applications of photosensitizers and laser light. (orig./MG)

    2014-11-01

    Full Text Available Synchronous bilateral renal cell carcinoma occurs in 1.4 % of cases. The probability of bilateral adrenal metastases from renal cell carcinoma is less than 0.5 %. The clinical observation presents a case of synchronous bilateral renal cell carcinoma and simultaneous metastatic involvement of both adrenal glands. A 55‑year-old male patient was adm tted with the signs of hematuria and anemia to the Unit of Urology, Clinic of General Surgery, Siberian State Medical University. He was found to have synchronous bilateral renal cell carcinoma and simultaneous bilateral adrenal involvement. Sequential surgical treatment – radical nephrectomy (with adrenal gland removal on the right side and, after 3 months, adrenalectomy and kidney resection on the left side were performed. All the organs removed displayed tumors that proved to be renal cell carcinomas (a clear cell variant. There were lymph node metastases in the right-sided renal portal. Postoperatively, the investigators performed hormone replacement therapy for adrenal insufficiency, an immunotherapy cycle, three cycles of targeted therapy withsorafenib and sunitinib (at an interval of 0.5–2 years, and insulin therapy for new-onset diabetes mellitus. The duration of a follow-up was 6.2 years. When describing the case, the patient was alive and showed a generalized tumorous process with extensive tumor involvement of the solitary kidney. Sunitinib therapy was used.

  20. FIGO Stage IIIB squamous cell carcinoma of the uterine cervix: natural history, treatment results, and prognostic factors

    International Nuclear Information System (INIS)

    Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Materials and Methods: The hospital and radiotherapy records of 1007 consecutive patients treated between 1960 and 1989 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. All patients were treated with radiation therapy (RT) either with curative intent (903 patients) or to palliate symptoms (104 patients). Patients who were selected for palliative treatment usually had a combination of adverse characteristics including massive tumor with bilateral pelvic wall fixation, hydronephrosis, bulky adenopathy, pathologic evidence of extrapelvic disease, and poor performance status. 64 (7%) of 903 patients failed to complete planned curative RT either because of progressive disease, complications, or poor compliance. Of 903 patients treated with curative intent, 319 (35%) were treated with external beam radiotherapy (EBRT) alone and 586 (65%) were treated with a combination of EBRT and intracavitary irradiation (ICRT). EBRT was usually delivered using 18-25 MV photons and ICRT was administered with Fletcher-Suit-Delclos applicators. Treatment philosophies evolved during the study period with greater emphasis placed on EBRT between 1966 and 1979 (52% treated with EBRT alone) compared with the other study years (15% treated with EBRT alone). 206 patients received investigational treatments including neutrons (69 pts), hyperbaric oxygen (66 pts), concurrent chemotherapy (29 pts), or neoadjuvant chemotherapy (42 pts). 875 patients have been followed until death. Median follow up for surviving patients is 171 months with only 9 surviving patients followed for 10%, or hgb < 10 gm% before treatment or at any time during radiotherapy. DSS was significantly better for patients whose treatment included ICRT (43% vs 21%; P< 0.0001). Also, patients who received

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

  3. Small cell carcinoma of the urinary bladder

    International Nuclear Information System (INIS)

    Small cell carcinoma of the urinary bladder (SCCUB) is an extremely rare tumor that exhibits aggressive behavior and accounts for approximately less than 1% of all primary bladder tumors. Small cell carcinoma generally occurs in the lung, accounting for 25% of all pulmonary malignancies. SCCUB exhibits a similar microscopic and immunohistochemical appearance to that of small cell carcinoma of the lung. There is no consensus about the standard therapy, owing to its rarity. Surgical resection seems to be the mainstay of treatment for patients with limited stage, together with neoadjuvant or adjuvant platinum-based chemotherapy. Radiation therapy has same small effect for palliative purposes, as well as being an alternative to radical cystectomy. Patients with advanced stage, although given platinum-based chemotherapy, have a poor prognosis. We herein review epidemiology, clinical presentation, diagnosis, pathological features, and current management of small cell carcinoma of the urinary bladder. (author)

  4. Combined modality treatment of regional small cell unidifferentiated carcinoma of the lung: a cooperative study of the RTOG and ECOG

    International Nuclear Information System (INIS)

    Between 1975 and 1979, 271 patients with regional small cell undifferentiated (including oat cell) carcinoma of the lung were entered into a study involving treatment by radiation therapy (4500 cGy (rad) in five weeks) to the primary tumor, mediastinum and supraclavicular lymph nodes, and a randomization to receive or not receive prophylactic treatment of the brain (3000 cGy in two weeks) and a randomization to prophylactic or delayed chemotherapy (cyclophosphamide and CCNU). Analysis of the data indicates that the median survival for responders (53 weeks) was significantly longer than that of the non-responders and partial responders (37 and 34 weeks). Median survival by treatment arm was 48 weeks for thoracic irradiation (TI), brain irradiation (BI), and early chemotherapy (CT), 44 weeks for TI alone, 41 weeks for TI and CT, 38 weeks for TI and BI. Regional complete and partial tumor responses were 52 and 25% for prophylactic chemotherapy and 44 and 35% for delayed chemotherapy. The site of first failure was regional in 12%, regional and distant simultaneously in 21%, and distant only in 46%. Elective brain irradiation significantly reduced the incidence of brain metastases from 21 and 5%, but did not improve survival

    Full Text Available Abstract Introduction Post-stereotactic radiation-induced neoplasms, although relatively rare, have raised the question of benefit regarding CyberKnife® treatments versus the risk of a secondary malignancy. The incidence of such neoplasms arising in the nervous system is thought to be low, given the paucity of case reports regarding such secondary lesions. Case presentation Here we describe a case of a 43-year-old Middle Eastern woman with primary clear cell renal cell carcinoma and a metastatic focus to the left brain parenchyma who presented with focal neurologic deficits. Following post-surgical stereotactic radiation in the region of the brain metastasis, the patient developed a secondary high-grade astrocytoma nearly 5 years after the initial treatment. Conclusion Although the benefit of CyberKnife® radiotherapy treatments continues to outweigh the relatively low risk of a radiation-induced secondary malignancy, knowledge of such risks and a review of the literature are warranted.

    The objective of the study is to perform a national survey of practices in early-stage squamous cell carcinoma (SCC) of the oropharynx (base of tongue and tonsils) targeting surgical and non-surgical procedures in France. A questionnaire concerning practices in surgery, radiotherapy, HPV screening, and two clinical cases were sent to all centers participating in the French Head and Neck Oncology Society, and to public hospitals listed as authorized to treat head and neck cancer according to the French National Cancer Institute (INCa). Sixty-four teams comprising almost all the University Hospitals and most of the Comprehensive Cancer Centers completed the survey questionnaire and responded to the clinical cases. Surgical and radiotherapy strategies were used in similar measure for early-stage SCC of the base of the tongue while tonsil lesions were mainly treated with surgery. The main arguments were disease control for the teams offering patients surgery, and functional results for those offering radiotherapy. However, concomitant chemoradiotherapy was chosen more frequently than radiotherapy alone in early-stage SCC of the base of tongue. Age and tobacco-alcohol addiction were decisive criteria in decision making for the majority of the teams. French oncology teams offered surgical and radiotherapy strategies in similar measure to treat early-stage SCC of the oropharynx (base of tongue and tonsils) as well as a high rate of multimodality therapy. Decision making was guided by the desire to achieve oncologic results adapted to the patient and his age, as well as functional preservation taking into account life expectancy. PMID:26253428

    Full Text Available Background: Basal cell carcinoma (BCC is the most common type of skin cancer in humans. Photodynamic therapy (PDT is a non-invasive therapeutic modality that may be considered as a valuable treatment option for BCC. This study was designed with the aim of evaluating the efficacy of PDT in treatment of BCC and factors that may affect the response rate. Materials and Methods: This clinical trial was conducted on 12 patients (28 BCC lesions who were treated with aminulevulinic acid (ALA-PDT, monthly, up to 6 sessions and the clinical response, cosmetic results, and possible side effects were evaluated. Results: The study was performed on 28 BCC lesions from 12 patients. Complete response was achieved in 9 (32.1% lesions. Complete response rate was higher in younger patients ( P < 0.01 and those with smaller lesions ( P < 0.001. Superficial type also had significant higher response rate ( P < 0.05. Patients with history of radiotherapy for the treatment of tinea capitis in childhood showed less response ( P < 0.05. Cosmetic results were excellent or good in 77.5% cases. After 6 months of follow-up, none of the resolved lesions recurred. Conclusion: PDT would be a good therapeutic option in treatment of BCC with acceptable efficacy and low side effects. Younger patients, superficial BCCs, and smaller lesions show better response to ALA-PDT. History of radiotherapy may be associated with a lower response rate.

    Full Text Available Mitul D Gandhi, Mark Agulnik Division of Hematology and Oncology, Robert H Lurie Comprehensive Cancer Center, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA Abstract: Squamous-cell cancer of the head and neck is a heterogeneous malignancy with treatment predicated on a multimodality therapy involving surgery, chemotherapy, and radiation. However, this approach results in durable responses in only a subset of patients, and is associated with significant toxicity. In advanced disease, multi-agent platinum-based chemotherapy produces only modest improvements in survival. Increased insight into tumor biology has demonstrated several critical oncogenic pathways offering prospects for targeted therapy that may improve upon the existing treatment strategies. The epidermal growth factor receptor is one such target, and directed therapy with the monoclonal antibody cetuximab has been extensively studied. Lapatinib is an oral agent that targets multiple transmembrane receptors within the epidermal growth factor receptor family, and offers a promising new approach to treatment. This paper reviews the rationale for and clinical activity of lapatinib in squamous-cell cancer of the head and neck.

    Full Text Available Abstract Background Despite the recently reported drop in the overall death rate from cancer, the estimated survival rate and number of deaths from oral cancer remain virtually unchanged. Early detection efforts, in combination with strategies for prevention and risk-reduction, have the potential to dramatically improve clinical outcomes. The identification of non-toxic, effective treatments, including complementary and alternative therapies, is critical if the survival rate is to be improved. Epidemiologic studies have suggested a protective effect from certain plant-derived foods and extracts; however, it has been difficult to isolate and identify the compounds most responsible for these observations. The primary purpose of this study was to investigate the response of human oral squamous cell carcinoma (OSCC to proanthocyanidin (PAC, a plant-derived compound that may inhibit the progression of several other cancers. Methods Using a series of in vitro assays, we sought to quantify the effects of PAC on OSCC, cervical carcinoma, and non-cancerous cell lines, specifically the effects of PAC on cell proliferation. Recent data suggest that infection with the human papillomavirus (HPV may also modulate the proliferative potential of OSCC; therefore, we also measured the effects of PAC administration on HPV-transfected OSCC proliferation. Results Our results demonstrated that PAC administration was sufficient to significantly suppress cellular proliferation of OSCC in a dose-dependent manner. In addition, the increased proliferation of OSCC after transfection with HPV 16 was reduced by the administration of PAC, as was the proliferation of the cervical cancer and non-cancerous cell lines tested. Our results also provide preliminary evidence that PAC administration may induce apoptosis in cervical and oral cancer cell lines, while acting merely to suppress proliferation of the normal cell line control. Conclusion These results signify that PAC may be

    The significant association with tobacco and alcohol combined with advanced age at time of diagnosis predispose head and neck squamous cell carcinoma (HNSCC) patients to increased risk of comorbidities. The presence of comorbidity affects treatment, treatment selection and subsequent outcome. Multiple studies have demonstrated comorbidity to be a strong prognostic factor for survival, and therefore comorbidity can be a major confounder in clinical trials. This review provides a summary of the current literature on comorbidity in head and neck cancer, measurements of comorbidity, the impact of comorbidity on treatment, treatment selection, and survival. A systematic search was performed in six electronic databases. In all, 31 papers were selected for this review. A meta-analysis on the prognostic impact of comorbidity was performed including 10 studies. Furthermore, 21 studies concerning comorbidity were reviewed. Several valid indices to classify comorbidity were described in the literature, none proven to be superior over the other. The prevalence of comorbidity increased with age and the presence of comorbidity influenced treatment and treatment selection. Furthermore, comorbidity was associated with lower socio economic status and increased the risk of early retirement after treatment. The meta-analysis on comorbidity as a prognostic factor, including 22,932 patients, showed that overall survival was significantly worsened among patients with comorbidity (HR = 1.38 (1.32–1.43)). Increasing comorbidity-score was associated with increased risk of death. Comorbidity is important in HNSCC and significantly impacts on overall survival. Trials concerning HNSCC should always include information on comorbidity and randomized trials should stratify patients according to comorbidity in order to avoid bias in the study

  12. Planoepitheliale cell carcinoma arising from ampullopancreatic unit

    International Nuclear Information System (INIS)

    Background: We report a case of planoepitheliale cell carcinoma located in the ampulla of Vater. We report the surgical results and pathological findings of a patient with an ampullary planoepitheliale cell carcinoma. From what we know it is the first case with successful surgical treatment. Case Report: A 58-year-old woman who presented with jaundice and preoperative endoscopic and radiological procedures could not show whether the tumour was carcinoma planoepitheliale. The clinical presentation, biochemical, radiographic and endoscopic investigation pronounced advanced pancreatic adenocarcinoma. Results: We performed pancreaticoduodenectomy with curative intention. Histological examination revealed: planoepitheliale cell carcinoma of the ampullo-pancreatic unit. Conclusions: In conclusion, preoperative endoscopic and radiological evaluations can all prove insufficient to distinguish between benign and malignant tumour. Thus, for malignant tumours surgeons may be forced to perform extensive surgery. (authors)

  16. Single-Antenna Microwave Ablation Under Contrast-Enhanced Ultrasound Guidance for Treatment of Small Renal Cell Carcinoma: Preliminary Experience

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the safety, effectiveness, and feasibility of microwave ablation (MWA) of small renal cell carcinomas (RCCs) in selected patients. Institutional review board and informed consent were obtained. From December 2007 to January 2009, 12 patients (8 male, 4 female) were enrolled in a treatment group, in which percutaneous MWA of small RCCs was performed under contrast-enhanced ultrasound guidance. The tumors were 1.7-2.9 cm in diameter (mean diameter, 2.0 cm).Therapeutic effects were assessed at follow-up with computed tomography. All patients were followed up for 3-14 months (mean, 6 months) to observe the therapeutic effects and complications (according to SIR classification). Assessment was carried out with CT imaging. No severe complications or unexpected side effects were observed after the MWA procedures. In all cases technical success was achieved. Clinical effectiveness was 100%; none of the patients showed recurrence on imaging. In conclusion, our preliminary results support the use of MWA for the treatment of small renal tumors. This technology can be applied in select patients who are not candidates for surgery, as an alternative to other ablative techniques.

    Shortly after treatment with the cytostatic combination of cisplatin and paclitaxel was generally accepted as the standard therapy for patients with epithelial ovarian carcinoma, many have come to regard the combination of carboplatin and paclitaxel as a better choice. The latter combination causes fewer side effects and may be used in the outpatient clinic. Conceivably, the carboplatin-paclitaxel scheme will shortly have to be adjusted again owing to results of current research. The intensive basic research of recent years, namely, is beginning to yield benefits for the therapeutic arsenal against ovarian carcinoma. Possibilities are inhibitors of the breakdown of extracellular matrix (such as marimastat) and inhibitors of signal transduction (such as trastuzumab). PMID:10578409

    The worldwide incidence of kidney cancer is estimated at 337,860 new cases per year in the International Agency for Research on Cancer's GLOBOCAN 2012 update, with an estimated 143,369 deaths annually. Over the past 10 years, there have been significant advances in the treatment of advanced/metastatic renal cell carcinoma, including the development of targeted therapies. Currently recommended first-line treatments include sunitinib, temsirolimus, bevacizumab plus interferon, and pazopanib, or high-dose interleukin-2 or sorafenib for selected patients. Recommended second-line treatments include all of the above agents, as well as everolimus and axitinib. Unfortunately, combination therapies have generally resulted in increased toxicity and little improvement in efficacy. Recent studies focused on identification of predictive biomarkers for responses to specific targeted therapies and have not been successful to date. Despite recent advances in targeted treatment for metastatic renal cell carcinoma, important questions regarding biomarkers of efficacy, and optimal combination and sequencing of agents remain to be answered. This paper reviews literature concerned with first-and second-line treatment of metastatic renal cell carcinoma and will discuss key issues in Latin America. PMID:26689508

    The present study shows that an application of cyclophosphamide (CY) supported by dendritic cell (DC)-based vaccines affected differentiation of the activity of CD4+ T cell subpopulations accompanied by an alteration in CD8+ cell number. Vaccines were composed of bone marrow-derived DCs activated with tumor cell lysate (BM-DC/TAgTNF-α) and/or genetically modified DCs of JAWS II line (JAWS II/Neo or JAWS II/IL-2 cells). Compared to untreated or CY-treated mice, the combined treatment of MC38 colon carcinoma-bearing mice resulted in significant tumor growth inhibition associated with an increase in influx of CD4+ and CD8+ T cells into tumor tissue. Whereas, the division of these cell population in spleen was not observed. Depending on the nature of DC-based vaccines and number of their applications, both tumor infiltrating cells and spleen cells were able to produce various amount of IFN-γ, IL-4 and IL-10 after mitogenic ex vivo stimulation. The administration of CY followed by BM-DC/TAgTNF-α and genetically modified JAWS II cells, increased the percentage of CD4+T-bet+ and CD4+GATA3+ cells and decreased the percentage of CD4+RORγt+ and CD4+FoxP3+ lymphocytes. However, the most intensive response against tumor was noted after the ternary treatment with CY + BM-DC/TAgTNF-α + JAWS II/IL-2 cells. Thus, the administration of various DC-based vaccines was responsible for generation of the diversified antitumor response. These findings demonstrate that the determination of the size of particular CD4+ T cell subpopulations may become a prognostic factor and be the basis for future development of anticancer therapy.

    Full Text Available Hepatocellular carcinoma (HCC is an epithelial tumor derived from hepatocytes; it accounts for 80% of all primary liver cancers and ranks globally as the fourth leading cause of cancer-related deaths. HCC treatment is a multidisciplinary and a multimodal task, with surgery in the form of liver resection and liver transplantation (LT representing the only potentially curative modality. However, there are variable opinions and discussions about applying these surgical options and using other supporting treatments. This article is a narrative review that includes articles published from 1984 to 2013 located by searching scientific databases such as PubMed, SCOPUS, and Elsevier, with the main keyword of hepatocellular carcinoma in addition to other keywords such as liver transplantation, liver resection, transarterial chemoembolization, portal vein embolization, bridging therapy, and downstaging. In this review, we focus mainly on the surgical treatment options offered for HCC, in order to illustrate the current relevant data available in the literature to help in applying these surgical options and to use other supporting treatment modalities when appropriate.

    Full Text Available Context Renal cell carcinoma has shown less response to systemic therapies including chemotherapy, radiotherapy andimmunotherapy than other cancers. Metastasis of renal cell carcinoma to the pancreas occurs, even after long term radicalnephrectomy, surgical resection remains the only potentially curative intervention. We performed surgery for pancreatic metastatic renal cell carcinoma and analyzed the results. Methods We retrospectively analyzed 11 patients who had undergone pancreatic resection or metastasectomy at our hospital from January 1994 to January 2010. Patient’s demographics, clinical variables, types of pancreatic resections (standard or atypical resection, primary histopathology, surgical outcomes, survival and disease free interval were examined. We compared the standard pancreatic resection to atypical resection (enucleation or enucleo-resection. Results Eleven patients underwent 14 pancreatic resections or metastasectomy (3 pancreaticoduodenectomy, 4 distal pancreatectomy, 1 completion of pancreatectomy, 4 enucleations and two enucleo-resections for pancreatic renal cell carcinoma metastasis. The median age was 73 years, the median time period between nephrectomy and finding of pancreatic metastasis was 11.4 years. One patient showed synchronous pancreatic metastatic lesions on radiology. One patient died from a splenic artery pseudoaneurysm rupture 35 days after the surgery. Major complications occurred in 4 patients with standard resection (one hemoperitoneum, three pancreatic fistulas, and in one patient with atypical resection (duodenal fistula; six patients with standard resection presented postoperative diabetes mellitus. Median survival age was 6.5 years (range 1-9 years. Two patients died of metastatic disease 5 to 6years, while 7 patients are alive and well 1 to 9 years after surgery. Conclusions According to these results and regardless of the small number of cases, atypical resection of metastatic renal cell

    Background - Squamous cell carcinoma of the esophagus is still a difficult tumor to treat with very poor prognosis. Aim - To compare the response to teletherapy treatment (external beam radiotherapy) alone versus teletherapy combined with brachytherapy for patients with advanced squamous cell carcinoma of the esophagus. Methods - Were studied 49 patients with advanced squamous cell carcinoma of the esophagus on clinical stage III (TNM-1999). They were separated into two groups. The first, underwent radiation therapy alone with linear accelerator of particles, average dose of 6000 cGy and the second to external beam radiation therapy at a dose of 5040 cGy combined with brachytherapy with Iridium 192 at a dose of 1500 cGy. Brachytherapy started one to two weeks after the end of teletherapy, and it was divided into three weekly applications of 500 cGy. Age, gender, race, habits (smoking and drinking), body mass index (BMI), complications with treatment benefits (pain relief and food satisfaction) and survival were analyzed. Results - The quality of life (food satisfaction, and pain palliation of dysphagia) were better in the group treated with external beam radiation therapy combined with brachytherapy. Survival was higher in the brachytherapy combined with external beam radiation therapy alone. Conclusion - Although the cure rate of squamous cell cancer of the esophagus is almost nil when treated with irradiation alone, this therapy is a form of palliative treatment for most patients in whom surgical contraindication exists.

    We studied safety and proof of concept of a phase I/II trial with chimeric antigen receptor (CAR) T-cells in patients with metastatic renal cell carcinoma (mRCC). The CAR was based on the G250 mAb that recognized an epitope of carboxy-anhydrase-IX (CAIX). Twelve patients with CAIX+ mRCC were treated in three cohorts with a maximum of 10 daily infusions of 2×10(7) to 2×10(9) CAR T-cells. Circulating CAR T-cells were transiently detectable in all patients and maintained antigen-specific immune functions following their isolation post-treatment. Blood cytokine profiles mirrored CAR T-cell presence and in vivo activity. Unfortunately, patients developed anti-CAR T-cell antibodies and cellular immune responses. Moreover, CAR T-cell infusions induced liver enzyme disturbances reaching CTC grades 2-4, which necessitated cessation of treatment in four out of eight patients (cohort 1+2). Examination of liver biopsies revealed T-cell infiltration around bile ducts and CAIX expression on bile duct epithelium, adding to the notion of on-target toxicity. No such toxicities were observed in four patients that were pretreated with G250 mAb (cohort 3). The study was stopped due to the advent of competing treatments before reaching therapeutic or maximum tolerated dose in cohort 3. No clinical responses have been recorded. Despite that, from this trial numerous recommendations for future trials and their immune monitoring could be formulated, such as choice of the target antigen, format and immunogenicity of receptor and how the latter relates to peripheral T-cell persistence.

  8. Limited external irradiation and interstitial 192iridium implant in the treatment of squamous cell carcinoma of the tonsillar region

    International Nuclear Information System (INIS)

    Between January 1976 and March 1982, 80 patients with histologically proven diagnosis of squamous cell carcinoma of the tonsillar region were treated with definitive radiotherapy. Sixty-five (81%) of these patients had locally advanced tumors (Stage III and IV); 49% of patients had clinically palpable cervical lymphadenopathy. All patients received a combined external megavoltage and interstitial irradiation. The dose of external irradiation was limited to 4500-5000 cGy over 41/2 to 51/2 weeks. This was followed by interstitial 192iridium implants to doses of 2000-2500 cGy in 50-60 hours for T1, T2 lesions and 3000-4000 cGy in 60-100 hours for T3, T4 lesions. The neck masses were also separately implanted to deliver additional doses of 2000-4000 cGy in 50-80 hours. Overall local tumor control was observed in 84% of patients with a minimum follow-up period of 2 years. An absolute 3-year disease free survival of the entire group was 72%. Treatment related complications such as soft tissue necrosis or osteoradionecrosis occurred in 6% (5/80) of patients. The salvage of neck failures and local failures was possible in 78 and 38% of patients, respectively, either by surgery or by re-irradiation employing interstitial 192iridium implants. Functional and esthetic integrity was well preserved in most cases

The objective of this study was to explore the efficacy and safety of nanoparticle albumin-bound paclitaxel (Nab-PTX combined with cisplatin (DDP in patients with metastatic esophageal squamous cell carcinoma (ESCC. Patients with histologically confirmed ESCC were treated with Nab-PTX 250 mg/m2 and DDP 75 mg/m2 intravenously on day 1, every 21 days. Evaluation was performed after every two cycles of therapy and the therapy was continued until disease progression or unacceptable toxicity. From April 2010 to December 2012, 33 patients were enrolled. Ten patients had recurrent and metastatic tumors after surgery and 23 patients were diagnosed with unresectable metastatic disease. Patients received a median of four cycles of therapy (ranging from two to six cycles. Twenty patients achieved partial response and nine patients achieved stable disease; no complete response was observed. The objective response rate was 60.6% and the disease control rate was 87.9%. The median progression-free survival was 6.2 months (95% confidence interval: 4.0 to 8.4 months and the median overall survival was 15.5 months (95% CI: 7.6 to 23.4 months. Only four patients experienced grade 3 adverse events, including vomiting, neutropenia, and sensory neuropathy. The most common adverse events were nausea/vomiting (81.8%, neutropenia (63.6%, leucopenia (48.5%, anemia (24.2% and sensory neuropathy (24.2%.

    Full Text Available Abstract Introduction In this case series and short review of the literature, we underline the impact of nephrectomy combined with sequential therapy based on cytokines, antiangiogenic factors, and mammalian target of rapamycin inhibitors along with metastasectomy on overall survival and quality of life in patients with metastatic clear cell renal carcinoma. Case presentation In the first of two cases reported here, a 53-year-old Caucasian man underwent a radical left nephrectomy for renal cell cancer and relapsed with a bone metastasis in his right humerus. He was treated with closed nailing and cytokine-based chemotherapy. For 5 years, the disease was stable and he had great improvement in quality of life. Subsequently, the disease relapsed in his lymph nodes, lung, and thorax soft tissue. He was then treated with antiangiogenic factors and mammalian target of rapamycin inhibitors. The disease progressed until September 2009, when he died of allergic shock during a blood transfusion, 9 years after the initial diagnosis of renal cell cancer. In the second case, a 54-year-old Caucasian man underwent a radical left nephrectomy for renal cell cancer. A year later, the disease progressed to his neck lymph nodes, and cytokine-based chemotherapy was initiated. While he was on cytokines, a solitary pulmonary nodule appeared and he underwent a metastasectomy. Nine months later, magnetic resonance imaging of his brain revealed a focal right occipitoparietal lesion, which was resected. After two years of active surveillance, the disease relapsed as a pulmonary metastasis and he was treated with an antiangiogenic factor. Further progressions presenting as enlarged axillary lymph nodes, chest soft tissue lesions, and thoracic spine bone metastases were sequentially observed. He then received a first-generation mammalian target of rapamycin inhibitor, an antiangiogenic factor, and later a second-generation mammalian target of rapamycin inhibitor and

  14. Local thermal ablation of renal cell carcinoma

    International Nuclear Information System (INIS)

    Purpose: With evolving local thermal ablation technology, the clinical application of thermal ablation has been actively investigated in the treatment for renal cell carcinoma. We review the evolution and current status of radiofrequency ablation and microwave ablation for renal cell carcinoma. Materials and methods: All articles published in English on radiofrequency ablation or microwave ablation as a treatment for renal cell carcinoma were identified with a MEDLINE® and PubMed® search from 1990 to 2010. Results: Local thermal ablation has several advantages, including keeping more normal renal units, relatively simple operation, easy tolerance, fewer complications, a shorter hospitalization and convalescence period. Long-term data has determined radiofrequency ablation is responsible for poor surgical candidates with renal cell carcinoma, however, tumor size, location and shape might affect the efficacy of radiofrequency ablation. Microwave ablation can induce large ablation volumes and yield good local tumor control. Associated complications appear to be low. Conclusions: Local ablative approaches seem to represent an attractive alternative to extirpative surgery for the treatment of small renal neoplasms in select patients. Potential developments include concepts to improve the accuracy and effectiveness of thermal ablation by improving the guiding, monitoring capabilities and detection capacity of multi-center lesions to provide at least equivalent cancer control to conventional surgery.

    Full Text Available Hepatocellular carcinoma (HCC is the fifth most common cancer worldwide, and it is responsible for up to one million deaths annually. Although multiple risk factors for HCC have been identifi ed, and despite preventive measures, the incidence of HCC continues to rise to epidemiologic proportions in the United States. In general, tumor resection and orthotopic liver transplantation are the treatment with the best outcome; however, HCC is generally diagnosed late in its course when patients are not eligible for curative treatment options. HCC is a relatively Chemo-refractory tumor secondary to heterogeneity of the tumor and the high rate of multidrug resistant gene expression. There are no standard treatments for HCC, multiple palliative treatment modalities have been used for patients with unresectable disease. None of these modalities have shown any superiority; and the retrospective nature of these available data has confounded any reasonable conclusions. Different institutions use different treatment schema dependent on the center expertise. Sorafenib, a tyrosine kinase inhibitor, has recently demonstrated a survival advantage in metastatic HCC, and if approved by the FDA, might become the standard of care. In this article we will review the rationale behind the currently available treatment options for HCC.

We report a 67-year-old woman with multifocal, infiltratingurothelial carcinoma and unilateral renal cell carcinoma. She was referred to our departmentbecause of painless gross hematuria. Cystoscopy, computed tomography and retrogradepyelography studies revealed bladder, bilateral renal and ureter UC. She was treated withtransurethral resection of the bladder tumor followed by bi...

  18. Intensity-modulated radiation treatment for head-and-neck squamous cell carcinoma-the University of Iowa experience

    International Nuclear Information System (INIS)

    Purpose: To review the University of Iowa experience with intensity-modulated radiotherapy (IMRT) in the treatment of head-and-neck squamous cell carcinoma. Methods and Materials: From October 1999 to April 2004, 151 patients with head-and-neck squamous cell carcinoma were treated with IMRT for curative intent. One patient was lost to follow-up 2 months after treatment and therefore excluded from analysis. Of the remaining 150 patients, 99 were treated with definitive IMRT, and 51 received postoperative IMRT. Sites included were nasopharynx, 5; oropharynx, 56; larynx, 33; oral cavity, 29; hypopharynx, 8; nasal cavity/paranasal sinus, 8; and unknown primary, 11. None of the patients treated with postoperative IMRT received chemotherapy. Of 99 patients who had definitive IMRT, 68 patients received concurrent cisplatin-based chemotherapy. One patient received induction cisplatin-based chemotherapy, but no concurrent chemotherapy was given. Three clinical target volumes (CTV1, CTV2, and CTV3) were defined. The prescribed doses to CTV1, CTV2, and CTV3 in the definitive cohort were 70-74 Gy, 60 Gy, and 54 Gy, respectively. For high-risk postoperative IMRT, the prescribed doses to CTV1, CTV2, and CTV3 were 64-66 Gy, 60 Gy, and 54 Gy, respectively. For intermediate-risk postoperative IMRT, the prescribed doses to CTV1, CTV2, and CTV3 were 60 Gy, 60 Gy, and 54 Gy. Results: The median follow-up was 18 months (range, 2-60 months). All living patients were followed for at least 6 months. There were 11 local-regional failures: 7 local failures, 3 regional failures, and 1 failure both in the primary tumor and regional lymph node. There were 16 patients who failed distantly, either with distant metastasis or new lung primaries. The 2-year overall survival, local progression-free survival, locoregional progression-free survival, and distant disease-free survival rates were 85%, 94%, 92%, and 87%, respectively.

    The number of molecular targeted agents for advanced renal cell carcinoma (RCC) has gradually increased, but evidence on the optimal order of selection for such agents has not yet caught up with this trend. In addition, timing of switching molecular targeted drugs may also become an important issue for controlling the disease as types of these drugs grow in number. Based on the fact that the efficacy of a rechallenge of the drug previously used suggests the recovery of the sensitivity, a cycl...

    Oral voriconazole is commonly used for treatment and prophylaxis of invasive fungal disease post-LTx. Development of cutaneous SCC has been described in adult LTx recipients, although it is extremely rare in children. We describe two Caucasian children who developed cutaneous SCC beyond three yr post-LTx. Both developed severe photosensitivity, actinic keratosis and required curative surgical excision of the cutaneous SCC lesions. Neither patient developed metastatic lesions nor had allograft dysfunction as a result of the SCC or the change in medical treatments. The effect of voriconazole on the development of malignant skin lesions is discussed and a recommendation on dermatologic surveillance, preventive measures against phototoxicity and early treatment of SCC are provided.

  4. CT differentiation of renal tumor invading parenchyma and pelvis: renal cell carcinoma vs transitional cell carcinoma

    International Nuclear Information System (INIS)

    The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

  10. The Essential Role of Radiotherapy in the Treatment of Merkel Cell Carcinoma: A Study From the Rare Cancer Network

    International Nuclear Information System (INIS)

    Purpose: To evaluate the role of postoperative radiotherapy (RT) in Merkel cell carcinoma (MCC). Methods and Materials: A retrospective multicenter study was performed in 180 patients with MCC treated between February 1988 and September 2009. Patients who had had surgery alone were compared with patients who received surgery and postoperative RT or radical RT. Local relapse-free survival (LRFS), regional relapse-free survival (RRFS), and distant metastasis-free survival (DMFS) rates were assessed together with disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) rates. Results: Seventy-nine patients were male and 101 patients were female, and the median age was 73 years old (range, 38–93 years). The majority of patients had localized disease (n = 146), and the remaining patients had regional lymph node metastasis (n = 34). Forty-nine patients underwent surgery for the primary tumor without postoperative RT to the primary site; the other 131 patients received surgery for the primary tumor, followed by postoperative RT (n = 118) or a biopsy of the primary tumor followed by radical RT (n = 13). Median follow-up was 5 years (range, 0.2–16.5 years). Patients in the RT group had improved LRFS (93% vs. 64%; p < 0.001), RRFS (76% vs. 27%; p < 0.001), DMFS (70% vs. 42%; p = 0.01), DFS (59% vs. 4%; p < 0.001), and CSS (65% vs. 49%; p = 0.03) rates compared to patients who underwent surgery for the primary tumor alone; LRFS, RRFS, DMFS, and DFS rates remained significant with multivariable Cox regression analysis. However OS was not significantly improved by postoperative RT (56% vs. 46%; p = 0.2). Conclusions: After multivariable analysis, postoperative RT was associated with improved outcome and seems to be an important component in the multimodality treatment of MCC.

  12. Treatment of small cell carcinoma of lung with combined high dose mediastinal irradiation, whole brain prophylaxis and chemotherapy

    International Nuclear Information System (INIS)

    Survival of patients with small cell carcinoma of lung, treated on a new combined radiotherapy-chemotherapy protocol, compares favorably with other regimens in the literature and our own previous combined approaches. Radiation, given after induction chemotherapy, consisted of whole brain prophylaxis in all 44 evaluable patients. Patients with limited disease were also treated to the primary and mediastinum to a high dose (5000 rad equivalent) using multiple fields. The new chemotherapy regimen consisted of induction with cyclophosphamide, doxorubicin, and vincristine alternated with cis-platinum and VP-16 (an epipodophyllotoxin) for two cycles, followed by consolidation with low dose cyclophosphamide and vincristine concurrent with irradiation. Patients with limited disease who achieved less than complete response, and all patients with extensive disease were not continued on maintenance chemotherapy. Out of 24 evaluable patients with limited disease, there was 73% survival at 1 year by life-table analysis, measured from treatment initiation. After induction, 16/24 of these limited disease patients were CR (complete responders): 20/24 were CR at completion of their irradiation. Out of 20 evaluable patients with extensive disease, there was 59% survival at 1 year by life-table analysis. Only 4/44 (9%) brain parenchymal relapses occurred, one at 3 months and one at 6 months after local failure and two in patients who did not become CRs, implicating a possible re-seeding mechanism. Five patients had central nervous system relapses outside of brain parenchyma (spinal epidural and leptomeningeal); in three patients this was the initial site of failure. Significant complications included leukopenia (50%) and thrombocytopenia (24%) primarily during induction, and chronic pulmonary fibrosis (25%), possibly contributing to two deaths

  14. Investigation of the treatment results of advanced squamous cell carcinoma of the oral cavity and clinical necessity of long-term follow-up

    International Nuclear Information System (INIS)

    It has been considered that oral cancer is cured if more than five years pass without recurrence or metastasis after the initial treatment. Treatment results are usually evaluated as a 5-year survival rate, but we sometimes find recurrence more than five years after the initial treatment. We retrospectively investigated treatment results by long-term follow-up of advanced squamous cell carcinoma of the oral cavity after radical surgery, and analyzed the relation between the period of follow-up and the time to recurrence. One hundred and sixteen patients with advanced squamous cell carcinoma of the oral cavity were enrolled between November 1994 and October 2004 in this study. Seventy-six patients were Stage III and 40 were stage IV, and the mean age of this cohort was 63.0 years. All patients received radical surgery with or without preoperative chemoradiotherapy and were followed for a minimum of 5 years. Overall actuarial survival of all patients was 77.8% at 10 years. The 10-year cumulative local and regional recurrence rates were 20.1% and 12.9%, respectively. The actuarial loco-regional recurrence rate was the highest within 2 years after initial treatment at 19.0%, and was seen in 3.4% even after 5 years. These results showed that it is necessary to follow-up patients with advanced oral cancer even beyond 5 years after the initial treatment because there was delayed loco-regional recurrence in 3.4%.

    International Nuclear Information System (INIS)

    Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.)

    2006-01-01

    BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most frequent primary malignant tumors in the world. Hepatic resection and liver transplantation are considered optimal for potential treatment of HCC. However, only 20%of HCCs can be surgically treated. And most of surgically-noneligible patients have to receive interventional managements including local ablation and transarterial chemoembolization (TACE). In this paper, we review the interventional treatments of HCC. DATA SOURCES:A literature search of PubMed database was conducted and research articles were reviewed. RESULTS: Percutaneous ethanol injection (PEI) is usually applied to small HCC for a complete necrosis. Radiofrequency ablation, an alternative to PEI, also causes tumor necrosis and needs fewer times of ablation. Other methods such as acetic acid injection, laser, microwave, etc have enriched local ablation for HCC. High intensity focus ultrasound (HIFU) is thought to be promising. TACE, another common modality, can improve the survival rate of patients with HCC. The newly developed embolic agents and adjuvant rAd-p53 gene therapy are well reported. CONCLUSIONS:Surgically-noneligible HCC can be treated with interventional procedures. Each method has its advantages and disadvantages. However, it is still pressing to develop ablative methods as well as new embolic agents for a better prognosis of HCC.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais.

    Human lymphoblastoid interferon-alpha was administered intramuscularly at a dose of 5 x 10(6) units/day to 20 metastatic renal cell carcinoma patients. For potentiating the antitumor effect of interferon, cimetidine was also given to them orally at a dose of 800 mg/day. The combination therapy obtained a complete response in three patients (15%) and a partial response in three (15%). Nine patients (45%) had stable disease and five (25%), progressive disease. All six patients who responded to the combination therapy had been nephrectomized and had pulmonary metastases. Two of them also had metastases to other sites (mediastinal lymph nodes and bone). The pulmonary metastases were significantly more receptive to interferon therapy than those at the other sites. The average times before a response was obtained were 2.2 months for a minor response, 2.7 months for a partial response and 3.0 months for a complete response, and the average duration of response was 26 months. The six patients who responded survived for a significantly longer period than the 14 non-responding patients treated with interferon in combination with cimetidine. The major toxicities encountered were fever, fatigue and anorexia due to interferon, and the combination therapy was well tolerated except in three patients. The results suggest that interferon-alpha and cimetidine combination therapy may be of use in the management of patients with metastatic renal cell carcinoma. PMID:2067120

    Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid. PMID:26589365

    Renal preservation therapy has been a promising concept for the treatment of localized renal cell carcinoma (RCC) for 20 years. Nowadays partial nephrectomy (PN) is well accepted to treat the localized RCC and the oncological control is proved to be the same as the radical nephrectomy (RN). Under the result of well oncological control, minimal invasive method gains more popularity than the open PN, like laparoscopic partial nephrectomy (LPN) and robot assisted laparoscopic partial nephrectomy...

    Full Text Available Cutaneous squamous cell carcinoma (SCC is the second most common non-melanoma skin cancer and tends to develop in sun-exposed cosmetic areas, including the ear. In this report, we describe two cases of SCC on the ear successfully treated with intra-arterial administration of peplomycin through a superficial temporal artery. In addition to this selective chemotherapy, we administered oral tegafur, which achieved complete remission of the tumor. These findings suggest that intra-arterial administration of peplomycin with tegafur is one of the optimal therapies for the treatment of SCC developing on the ear.

  17. Strong CD8+ T-cell responses against tumor-associated antigens prolong the recurrence-free interval after tumor treatment in patients with hepatocellular carcinoma

    International Nuclear Information System (INIS)

    We investigated whether tumor-specific CD8+T-cell responses affect tumor-free survival as well as the relationship between CD8+T-cell responses against tumor-associated antigens (TAAs) and the clinical course after tumor treatment in patients with hepatocellular carcinoma (HCC). Twenty patients with HCC that were treated by radiofrequency ablation or trans-catheter chemo-embolization (TACE) and in whom HCC was undetectable by ultrasonography, CT, and/or MRI 1 month after treatment were enrolled in the study. Before and after treatment for HCC, analyses of TAA (glypican-3, NY-ESO-1, and MAGE-1)-specific CD8+T-cell responses were evaluated with an interferon-γ enzyme-linked immunospot (ELISpot) assay using peripheral CD8+T-cells, monocytes, and 104 types of 20-mer synthetic peptide overlapping by 10 residues and spanning the entirety of the 3 TAAs. Sixteen out of 20 patients (80%) showed a positive response (≥10 TAA-specific cells/105 CD8+T-cells) before or after treatment. When we performed univariate analysis of prognostic factors for the tumor-free period in the 20 patients, platelet count, prothrombin time, and the number of TAA-specific CD8+T-cells after treatment were significant factors (P=0.027, 0.030, and 0.004, respectively). In multivariate analysis, the magnitude of the TAA-specific CD8+T-cell response (≥40 TAA-specific cells/105 CD8+T-cells) was the only significant prognostic factor for a prolonged tumor-free interval (hazard ratio 0.342, P=0.022). Our results suggest that strong TAA-specific CD8+T-cell responses suppress the recurrence of HCC. Immunotherapy to induce TAA-specific cytotoxic T lymphocytes by means such as the use of peptide vaccines should be considered for clinical application in patients with HCC after local therapy.

  20. Sensitivity tests of combination treatment with interleukin-2 and radiation against renal cell carcinoma using in vivo like growing culture system

    International Nuclear Information System (INIS)

    We studied the effect of the combined therapy with interleukin-2 (IL-2) and radiation on renal cell carcinoma using an in vivo like growing culture system. We tested renal cell carcinoma obtained at surgery. After tumors were sliced into 2-mm square specimens, they were placed on a collagen gel-matrix filled with medium, and cultured for 7 days. 5 and 10 Gy were irradiated 3 days after the beginning of cell cultures. We also tested 100 JRU/ml of IL-2 added to each culture medium. The killing activity of each treatment was measured by the rate of 3H-thymidine uptake. In the 5 Gy groups (n=9), we observed a significant effect in one treated with radiation alone (11.1%) and in 4 treated with the combined therapy (44.4%). Of these 4 having a significant effect with the combined therapy, one also had it with either radiation alone or combined therapy. The combined therapy was significantly effective compared with radiation alone. One had a significant effect with the combined therapy, and the remaining 2 had a significant effect by either combined therapy or radiation alone. In the 10 Gy group (n=12), a significant effect was seen in one with IL-2 treatment alone (8.3%), one with radiation alone (8.3%), and 4 with the combined therapy (33.3%). Of these 4 cases having a significant effects with the combined therapy, one had it by either radiation alone or the combined therapy, and the combined therapy was more effective than radiation alone. Two cases had a significant effect by the combined therapy, and the remaining one had it by either the combined therapy or radiation alone. We conclude that the combined therapy with IL-2 and radiation is effective for renal carcinoma, especially in the group irradiated with 5 Gy. (J.P.N.)

    1999-06-01

    Patients with metastatic renal cell carcinoma continue to present a therapeutic challenge. Current therapeutic approaches involve surgery and various types of immunotherapy. The rationale for this latter form of therapy include the observations of spontaneous tumor regression, the presence of a T-cell-mediated immune response, and the tumor responses observed in patients receiving cytokine therapy. Analysis of prognostic factors in these patients demonstrates that clinical responses occur most frequently in individuals with good performance status. The cytokines interleukin-2 (IL-2, aldesleukin [Proleukin], interferon-alfa (Intron A, Roferon-A), or the combination produce responses in 15% to 20% of patients. Randomized trials suggest that administration of interferon-alfa may result in a modest improvement in median survival. Investigation of the molecular genetics of renal cell carcinoma and the presence of T-lymphocyte immune dysregulation have suggested new therapeutic strategies. Further preclinical and clinical studies investigating inhibitors of angiogenesis or pharmacologic methods to reverse immune dysregulation are ongoing. Therapeutic results in patients with renal cell carcinoma remain limited, and investigational approaches are warranted. PMID:10378218

    Full Text Available Multiple primary malignant neoplasms (MPMN is a rare clinical entity in which two primary malignancies are encountered in the same individual which can be synchronous (second primary within 6 months or metachronous (beyond 6 months. We present a case of a 41-year-old male who underwent left partial nephrectomy for suspected renal cell carcinoma and it was confirmed based on histopathology. The gallbladder was normal on contrast-enhanced computed tomogram (CECT abdomen. Follow-up CECT done 1 year later showed no enhancing masses in both kidneys, but incidentally porcelain gallbladder was detected. An elective open cholecystectomy was done for acalculous porcelain gall bladder owing to its premalignant nature. We report this case to highlight the relative risk of second primaries in patients treated for primary malignancies and that relevant premalignant conditions should be managed as possible second malignancies to avoid potential complications.

    2004-12-01

    Renal cell carcinoma accounts for 2-3% of all malignancies. The most common subtype [85%] is the clear cell variant. A total of 30% of patients present with metastatic disease at diagnosis and another 30-40% will develop metastases during the course of the disease. Conventional cancer treatment is not effective, but cytokines including recombinant interleukin-2 (aldesleukin) have demonstrated clinical activity of various degrees. This drug profile provides a review of the literature on studies using aldesleukin in patients with metastatic renal cell carcinoma. Aldesleukin has been used in different dose schedules applying various administration routes, as either monotherapy or in combination with other cytokines, chemotherapy, endocrine treatment and adoptive cellular immunotherapy. Although a large number of randomized trials have been performed with different treatment strategies, it still remains uncertain whether the dose or combination of aldesleukin with other agents substantially influence treatment outcome. It appears that factors other than those that are treatment related are responsible for the course of the disease. PMID:15606326

  8. Targeting Btk with ibrutinib inhibit gastric carcinoma cells growth

    2016-01-01

    Bruton’s tyrosine kinase (Btk) is a member of the Tec-family non-receptor tyrosine kinases family. It has previously been reported to be expressed in B cells and has an important role in B-cell malignancies. While the roles of Btk in the pathogenesis of certain B-cell malignancies are well established, the functions of Btk in gastric carcinoma have never been investigated. Herein, we found that Btk is over-expressed in gastric carcinoma tissues and gastric cancer cells. Knockdown of Btk expression selectively inhibits the growth of gastric cancer cells, but not that of the normal gastric mucosa epithelial cell, which express very little Btk. Inhibition of Btk by its inhibitor ibrutinib has an additive inhibitory effect on gastric cancer cell growth. Treatment of gastric cancer cells, but not immortalized breast epithelial cells with ibrutinib results in effective cell killing, accompanied by the attenuation of Btk signals. Ibrutinib also induces apoptosis in gastric carcinoma cells as well as is a chemo-sensitizer for docetaxel (DTX), a standard of care for gastric carcinoma patients. Finally, ibrutinib markedly reduces tumor growth and increases tumor cell apoptosis in the tumors formed in mice inoculated with the gastric carcinoma cells. Given these promising preclinical results for ibrutinib in gastric carcinoma, a strategy combining Btk inhibitor warrants attention in gastric cancer. PMID:27508020

    In the recent years, a number of targeted therapies have been approved for first-line treatment of patients with metastatic renal cell carcinoma. A systematic review was conducted to assess the clinical efficacy, safety and effect of all first-line treatments evaluated to date on health-related quality of life (HRQoL). A systematic search of Embase, Cochrane and MEDLINE databases was performed to identify randomized controlled trials (1980-2015) evaluating any targeted therapy/immunotherapy against placebo or any other targeted intervention/immunotherapy in treatment-naive patients with metastatic renal cell carcinoma. Conference proceedings from major cancer congresses (2007-2015) were handsearched. Sixteen randomized controlled trials were identified, mostly phase III. Overall, targeted therapies were associated with either improved [sunitinib, bevacizumab+interferon α (IFNα) and temsirolimus] or comparable (sorafenib) progression-free survival (PFS) versus IFNα monotherapy. Sunitinib demonstrated comparable PFS and overall survival to pazopanib, comparable PFS to sorafenib and shorter PFS compared with bevacizumab+IFNα (although no conclusions were made with regard to superiority/inferiority). Compared with sorafenib, tivozanib demonstrated a significantly longer PFS, and both tivozanib and axitinib demonstrated higher response rates. Nintedanib demonstrated comparable PFS and overall survival to sunitinib in a phase II trial. Temsirolimus, sunitinib and sorafenib treatment led to better HRQoL versus IFNα; pazopanib was associated with better HRQoL versus sunitinib. No direct meta-analyses or indirect treatment comparison analysis were undertaken because of noncomparability of the trials. In general, targeted therapies demonstrated favourable clinical efficacy and improved HRQoL compared with IFNα monotherapy. The newer therapies, tivozanib and axitinib (but not nintedanib), appeared to exhibit greater clinical benefit (response rate) than older tyrosine

    The outcome of treatment of advanced renal cell carcinoma is disappointing. In interferon (IFN)-treated patients, the high incidence of adverse effects causes many patients to withdraw from treatment. This 12-week randomized study compared the incidence of toxicity associated with high-dose IFN monotherapy (15 x 10(6) U thrice weekly) and treatment with the combination of low-dose IFN (5 x 10(6) U thrice weekly) and 6 mg/m2 vinblastine (VBL) every 14 days in 100 consecutive patients. There was no significant difference in response rate between treatment arms (42% IFN vs. 34% IFN + VBL) or between subgroups (by tumor location). Combined treatment was associated with a significantly lower incidence of fever, fatigue, and weight loss but with a higher incidence of leukopenia. There was no significant difference in the incidence of other events. More patients treated with IFN monotherapy required bed rest, and overall treatment costs were 60% higher than for combined treatment. It is concluded that combined treatment with low-dose IFN and VBL, without loss of short-term efficacy, is better tolerated and less expensive than high-dose IFN monotherapy. PMID:10954911

    Renal cell carcinoma is the most common renal tumor in adults. Clear cell carcinoma represents 85% of all histological subtypes. In February 2012 a 72-year-old woman came to our department due to the appearance of massive hemoptysis and pharyngodinia. Previously, this patient was diagnosed with a renal cell carcinoma treated with left nephrectomy. We observed an exophytic, grayish, and ulcerated mass in the left tonsillar lodge and decided to subject the patient to an immediate tonsillectomy....

  2. Treatment results of combined interstitial high-dose-rate brachytherapy and ablative surgery for advanced-stage oral and oropharyngeal squamous cell carcinoma

    International Nuclear Information System (INIS)

    Oral and oropharyngeal squamous cell carcinoma in 38 patients were treated over a period of 7 years (1988-1994) by HDR interstitial brachytherapy using Gammamed trademark 12i equipment. Pretreatment of patients in terms of irradiation and surgery differed (33 irradiated with a total dose between 60.0 and 75.6 Gy, including 8 patients with additional surgery; 1 patient with surgery alone, and 4 patients without any pretreatment). Indications for interstitial brachytherapy differed according to individual responses to treatment and medical histories. Interstitial brachytherapy was successful in the majority of patients, i.e. complete remission: 12, partial remission: 19, no change: 2, progression: 5. Local control and overall survival including patients with surgical treatment was 59% and 81% at 6 months and 47% and 49% after 12 months, respectively. (orig.)

    The mononuclear phagocytic system is categorized in three major groups: monocyte-derived cells (MCs), dendritic cells and resident macrophages. During breast cancer progression the colony stimulating factor 1 (CSF-1) can reprogram MCs into tumor-promoting macrophages in the primary tumor. However, the effect of CSF-1 during colonization of the brain parenchyma is largely unknown. Thus, we analyzed the outcome of anti-CSF-1 treatment on the resident macrophage population of the brain, the microglia, in comparison to MCs, alone and in different in vitro co-culture models. Our results underline the addiction of MCs to CSF-1 while surprisingly, microglia were not affected. Furthermore, in contrast to the brain, the bone marrow did not express the alternative ligand, IL-34. Yet treatment with IL-34 and co-culture with carcinoma cells partially rescued the anti-CSF-1 effects on MCs. Further, MC-induced invasion was significantly reduced by anti-CSF-1 treatment while microglia-induced invasion was reduced to a lower extend. Moreover, analysis of lung and breast cancer brain metastasis revealed significant differences of CSF-1 and CSF-1R expression. Taken together, our findings demonstrate not only differences of anti-CSF-1 treatment on MCs and microglia but also in the CSF-1 receptor and ligand expression in brain and bone marrow as well as in brain metastasis.

  7. Contribution of transcription factor, SP1, to the promotion of HB-EGF expression in defense mechanism against the treatment of irinotecan in ovarian clear cell carcinoma

    International Nuclear Information System (INIS)

    Ovarian clear cell carcinoma (OCCC) is a worst histological subtype than other ovarian malignant tumor. Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a promising target for ovarian cancer therapy. The aims of this study were to validate the efficacy of HB-EGF–targeted therapy for OCCC and to identify the transcription factor that contributed to the induction of HB-EGF by SN38 treatment in OCCC cells. HB-EGF was highly expressed in OCCC cells, and an increase of HB-EGF was induced by SN38 which had only antitumor effect among conventional anticancer agents on OCCC. A specific inhibitor of HB-EGF, a cross-reacting material 197 (CRM197), led to a synergistic increase in the number of apoptotic OCCC cells with the treatment of SN38. The luciferase assay with 5′-deletion promoter constructs identified a GC-rich element between −125 and −178 (the distal transcription start site was denoted +1) as a cis-regulatory region, and the treatment of SN38 induced luciferase activity in this region. An in silico and chromatin immunoprecipitation analysis estimated that SP1 bound to the cis-regulatory region of HB-EGF in OCCC cells. Real-time PCR and cell viability assays showed that the transfection of a small interfering RNA targeting SP1 suppressed the expression of HB-EGF induced by SN38, resulting in the enhanced sensitivity of SN38. Taken together, these results indicate that induction of HB-EGF expression contributed to defense mechanism against treatment of SN38 through the transcriptional activity of SP1 in OCCC cells

  8. Treatment of squamous cell carcinomas of the floor of the mouth and tongue by interstitial high-dose-rate irradiation using iridium-192

    International Nuclear Information System (INIS)

    The results are presented of afterloading high-dose-rate-radiation with iridium-192 in 34 patients with squamous cell carcinomas of the floor of the mouth and tongue. Some patients were also treated surgically or given percutaneous radio- or chemotherapy. At the time of diagnosis, 28.0% had a T2 tumour, 41.9% a T3 tumour and 30.1% a T4 tumour. 41.2% had positive lymph nodes and 2.9% distant metastases. The response rate was 64.7%, 26.5% of which were complete remissions and 38.2% partial remissions. In 61.8% of cases, the tumour was recurrent and responded with a rate as high as 57.2%, 23.9% of which were complete remissions and 33.3% partial remissions. Survival times were dependent upon therapy results. The mean survival of patients with complete remission was 40.3 months, with partial remission 16.1 months as opposed to 7.2 and 3.5 months respectively in patients showing no change or progressive disease. It can be concluded that afterloading therapy using high-dose-rate-radiation with iridium-192 achieves good palliative results and should be looked at as a supplementary treatment modality for squamous cell carcinomas of the floor of the mouth and tongue.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

  12. Bone Marrow–Derived Stromal Cell Therapy in Cirrhosis: Clinical Evidence, Cellular Mechanisms, and Implications for the Treatment of Hepatocellular Carcinoma

    International Nuclear Information System (INIS)

    Current treatment options for hepatocellular carcinoma (HCC) are often limited by the presence of underlying liver disease. In patients with liver cirrhosis, surgery, chemotherapy, and radiation therapy all carry a high risk of hepatic complications, ranging from ascites to fulminant liver failure. For patients receiving radiation therapy, cirrhosis dramatically reduces the already limited radiation tolerance of the liver and represents the most important clinical risk factor for the development of radiation-induced liver disease. Although improvements in conformal radiation delivery techniques have improved our ability to safely irradiate confined areas of the liver to increasingly higher doses with excellent local disease control, patients with moderate-to-severe liver cirrhosis continue to face a shortage of treatment options for HCC. In recent years, evidence has emerged supporting the use of bone marrow–derived stromal cells (BMSCs) as a promising treatment for liver cirrhosis, with several clinical studies demonstrating sustained improvement in clinical parameters of liver function after autologous BMSC infusion. Three predominant populations of BMSCs, namely hematopoietic stem cells, mesenchymal stem cells, and endothelial progenitor cells, seem to have therapeutic potential in liver injury and cirrhosis. Preclinical studies of BMSC transplantation have identified a range of mechanisms through which these cells mediate their therapeutic effects, including hepatocyte transdifferentiation and fusion, paracrine stimulation of hepatocyte proliferation, inhibition of activated hepatic stellate cells, enhancement of fibrolytic matrix metalloproteinase activity, and neovascularization of regenerating liver. By bolstering liver function in patients with underlying Child's B or C cirrhosis, autologous BMSC infusion holds great promise as a therapy to improve the safety, efficacy, and utility of surgery, chemotherapy, and hepatic radiation therapy in the

  14. Intensity-modulated radiotherapy vs. conventional radiotherapy in the treatment of anal squamous cell carcinoma: A propensity score analysis

    International Nuclear Information System (INIS)

    Background and purpose: Definitive chemoradiation is the standard management for anal squamous cell carcinoma (ASCC); more conformal pelvic radiotherapy using intensity modulated radiotherapy (IMRT) minimizes toxicity but may increase locoregional recurrences (LRR). We compared IMRT and conventional radiotherapy (CRT) outcomes in ASCC patients. Material and methods: We retrospectively reviewed records of 223 ASCC patients treated at Memorial Sloan-Kettering Cancer Center from 1991 to 2010. Forty-five patients received IMRT and 178 CRT. We determined locoregional recurrence-free survival (LRFS), distant metastases-free survival (DMFS), and overall survival (OS) for each radiation modality. A propensity score analysis was performed using potentially confounding variables. Locoregional and distant patterns of failure for CRT and IMRT were compared. Results: Patients treated with IMRT had significantly higher N stage (P < .01), and were less likely to be treated with induction chemotherapy (P = .01). The 2-year LRFS, DMFS, and OS were 87%, 86%, and 93%, respectively, for IMRT; and 82%, 88%, 90%, respectively, for CRT; with no significant difference in outcomes by univariate analysis or in a propensity score analysis adjusted for disparity between the groups. Conclusions: This large, single-institution experience of definitive chemoradiation for ASCC using CRT vs. IMRT demonstrates that outcomes are not compromised by more conformal radiotherapy. In the absence of prospective, multi-institutional, randomized trials of IMRT in ASCC, these retrospective data, using methods to minimize bias, can help to establish the role of IMRT in the definitive therapy of ASCC

  15. Brain natriuretic peptide precursor (NT-pro-BNP) levels predict for clinical benefit to sunitinib treatment in patients with metastatic renal cell carcinoma

    International Nuclear Information System (INIS)

    Sunitinib is an oral, multitargeted tyrosine kinase inhibitor that has been approved for the treatment of metastatic renal cell carcinoma. Although the majority of sunitinib-treated patients receive a clinical benefit, almost a third of the patients will not respond. Currently there is no available marker that can predict for response in these patients. We estimated the plasma levels of NT-pro-BNP (the N-terminal precursor of brain natriuretic peptide) in 36 patients that were treated with sunitinib for metastatic clear-cell renal carcinoma. From the 36 patients, 9 had progressive disease and 27 obtained a clinical benefit (objective response or disease stabilization). Increases in plasma NT-pro-BNP were strongly correlated to clinical outcome. Patients with disease progression increased plasma BNP at statistically significant higher levels than patients that obtained a clinical benefit, and this was evident from the first 15 days of treatment (a three-fold increase in patients with progressive disease compared to stable NT-pro-BNP levels in patients with clinical benefit, p < 0.0001). Median progression-free survival was 12.0 months in patients with less than 1.5 fold increases (n = 22) and 3.9 months in patients with more than 1.5 fold increases in plasma NT-pro-BNP (n = 13) (log-rank test, p = 0.001). This is the first time that a potential 'surrogate marker' has been reported with such a clear correlation to clinical benefit at an early time of treatment. Due to the relative small number of accessed patients, this observation needs to be further addressed on larger cohorts. More analyses, including multivariate analyses are needed before such an observation can be used in clinical practice

    Bauden, Monika; Tassidis, Helena; Ansari, Daniel

    2015-07-01

    Apicidin is a potent histone deacetylase inhibitor (HDACI) that selectively binds to histone deacetylases (HDACs) class I and interferes with the deacetylation process, which results in modification of acetylation level of cellular proteins. The aim of the study was to investigate the potential time and dose dependent cytotoxicity of the test compound, Apicidin, in pancreatic cancer cells Capan-1 and Panc-1 as well as estimate maximal tolerable dose (MTD) of the test agent and determine EC50 using four complementary colorimetric cytotoxicity or viability assays. The cells were treated with increasing concentrations of Apicidin (0-5000nM) for 2, 4 and 6h (short term exposure) or 24, 48 and 72h (long term exposure) before conducting cytotoxic analyses with lactate dehydrogenase assay or viability analyses with sulforhodamine B (SRB), methyl tetrazolium (MTT) and crystal violet (CV) assays. In order to investigate whether Apicidin irreversibly affects the cells already during the short term exposure, the medium containing Apicidin was removed and replaced with fresh culturing medium after 6h of treatment. The cells were then incubated for additional 24, 48 or 72h before carrying out the analysis. The results obtained from cytotoxicity and viability assays indicated, that Apicidin was well tolerated by both cell lines at concentrations below 100nM at any given time point and at all applied concentrations during the short term (6h or less) treatment. Continuous prolonged term exposures (48h or greater) of the cells to Apicidin with concentration exceeding 100nM resulted in significantly increasing cytotoxicity and sustained significant loss of cell viability. Moreover, long term exposure of pancreatic cancer cells Capan-1 and Panc-1 to Apicidin concentrations exceeding 100nM showed an initial anti-proliferative effect before cytotoxicity onset. In summary, MTD was exposure time dependent and estimated to 100nM for long term treatment and to at least 5000nM for treatment

Glyciphon is diglycidyl ether of methylphosphonic acid, which has been synthesized at the A. E. Arbuzov Institute of Organic and Physical Chemistry, Kazan Research Center, Russian Academy of Sciences, belongs to a class of organophosphors epoxides. The drug has been experimentally tested by Kazan scientists who revealed the selectivity of its antiblastoma activity, relatively low toxicity, and high safety when it was used long. The antiproliferatve activity of glyciphon in inhibiting DNA synthesis, retarding all mitotic phases, and blocking the entry of cells into S and M phases plays an important role in its mechanism of antiblastoma action. Glyciphon ointment 30 % is effective in the treatment of primary BCC (solitary tumors and polyneoplasms and its recurrences after radiation and surgery in the absence of a side skin resorption effect. It may be successfully used to treat BCC that are refractory to radiotherapy and surgical dissection and to detect latent foci of multiple BCC.

    Full Text Available We previously published our and Johns Hopkins data titled: "Platinum-based therapy in adenosquamous pancreatic cancer: experience at two institutions” [1]. We will here like to submit a related case report as a letter to the editor to JOP in reference to the above paper. Squamous cell carcinoma of the pancreas has various reported incidence rates, ranging from 0.5% to as high as 5% of pancreatic ductal carcinomas [2, 3]. Of the 1300 cases of pancreatic cancers observed at autopsy in a survey in Japan in 1992, 0.7% were squamous cell carcinoma [4]. A Mayo clinic review of very rare exocrine tumors showed an even rarer incidence of squamous cell carcinoma when compared to acinar and small cell carcinoma of the pancreas [5]. This discrepancy in the reported incidence rates related to the fact that some of the cases represent adenosquamous carcinoma rather than pure squamous cell carcinoma of pancreas. In an analysis of 25 patients, mean age at diagnosis of pancreatic squamous cell carcinoma was 62 years (range: 33–80 years and there was no gender difference [6]. There is no study about the molecular profile of squamous carcinoma of the pancreas. There are no retrospective or prospective studies about the best therapy for these tumors

    Recently, vitamin D analogues have shown antineoplastic effect in several diseases. Vitamin D analogues exert its effect by interacting with the vitamin D receptor (VDR). Studies of VDR in transitional cell carcinoma (TCC) have not been reported. The purpose of the present study was therefore.......05). Similarly, also tumor grade appeared to be related to the number of cells expressing the receptor. Normal urothlium also expressed VDR but only with low intensity. Our study shows that TCC cells possess the VDR receptor which may make them capable to respond to stimulation with vitamin D, but functional...... studies of vitamin D's effect on TCC cells in vitro are necessary before the efficacy of treatment with vitamin D analogues in TCC can be evaluated in patients....

    Full Text Available Spindle cell carcinoma (SpCC is a unique variant of squamous cell carcinoma (SCC. SpCC confined to the nasal cavity is extremely rare, with only one case having been previously reported. We present a case report of nasal cavity SpCC and review the literature on this rare entity. A 29-year-old male presented with intermittent epistaxis from the left nasal cavity. On physical examination, the patient had an ulcerated mass in the left nasal vestibule and a biopsy showed a proliferation of spindle and epitheliod cells. The patient underwent wide local excision of the mass via a lateral alotomy approach and reconstruction with a composite conchal bowl skin and cartilage graft. Histologically, the mass had dyplastic squamous epithelium and spindle-shaped cells admixed with epitheliod cells. Immunohistochemistry was only positive for pancytokeratin AE1/AE3 and vimentin. Six months after surgery, the patient continues to have no evidence of disease. On literature review, only one previous case of SpCC confined to the nasal cavity was identified. We present a rare case of nasal cavity SpCC. No definite treatment protocol exists for this unique entity, but we believe that this tumor should primarily be treated with aggressive, wide local excision. Adjuvant radiation and/or chemotherapy have also been used anecdotally.

    Full Text Available Abstract Background Rectal squamous cell carcinoma (SCC is a rare tumor. The incidence of this malignancy has been reported to be 0.25 to 1 per 1000 colorectal carcinomas. From a review of the English literature 55 cases of SCC of the rectum have been published. In this study we report a rectal metastatic SCC to the liver, discussing the efficacy of aggressive adjuvant and neo-adjuvant therapies on survival and prognosis. Case presentation A 39-year-old female patient with a pure SCC of the rectum diagnosed endoscopically is presented. The patient underwent initially neoadjuvant chemo-radiotherapy and then abdominoperineal resection with concomitant bilateral oophorectomy and hysterectomy, followed by adjuvant chemo-radiotherapy. Five months after the initial operation liver metastasis was demonstrated and a liver resection was carried out, followed by adjuvant chemotherapy. Eighteen months after the initial operation the patient is alive. Conclusion Although prognosis of rectal SCC is worse than that of adenocarcinoma, an aggressive therapeutic approach with surgery as the primary treatment, followed by combined neo- and adjuvant chemo-radiotherapy, may be necessary in order to improve survival and prognosis.

  10. Percutaneous Cryoablation for Renal Cell Carcinoma

    2015-06-01

    Full Text Available Renal cell carcinoma (RCC is the most common type of kidney cancer in adults. Nephron sparing resection (partial nephrectomy has been the “gold standard” for the treatment of resectable disease. With the widespread use of cross sectional imaging techniques, more cases of renal cell cancers are detected at an early stage, i.e. stage 1A or 1B.  This has provided an impetus for expanding the nephron sparing options and especially, percutaneous ablative techniques.  Percutaneous ablation for RCC is now performed as a standard therapeutic nephron-sparing option in patients who are poor candidates for resection or when there is a need to preserve renal function due to comorbid conditions, multiple renal cell carcinomas, and/or heritable renal cancer syndromes. During the last few years, percutaneous cryoablation has been gaining acceptance as a curative treatment option for small renal cancers. Clinical studies to date indicate that cryoablation is a safe and effective therapeutic method with acceptable short and long term outcomes and with a low risk, in the appropriate setting.  In addition it seems to offer some advantages over radio frequency ablation (RFA and other thermal ablation techniques for renal masses.

    Full Text Available Abstract Introduction The differential diagnosis of neutropenia includes medications, infections, autoimmune diseases, and deficiencies of Vitamin B12 and folate. The association of Vitamin B6 deficiency with severe neutropenia is a rare finding. Case presentation A 51-year-old Caucasian woman presented with fever and profound neutropenia (48 neutrophils/uL. Her clinical history included non-Hodgkin lymphoma, in remission following treatment with allogeneic bone marrow transplantation, quiescent chronic graft-versus-host disease, and squamous cell carcinoma of the skin metastatic to cervical lymph nodes. Medications included atenolol, topical clobetasol, Ditropan (oxybutynin, prophylactic voriconazole, prophylactic valganciclovir, Soriatane (acitretin, and Carac (fluorouracil cream. The bone marrow was hypocellular without metastatic cancer or myelodysplasia. Neutropenia did not respond to stopping medications that have been associated with neutropenia (valganciclovir, voriconazole and Soriatane or treatment with antibiotics or granulocyte colony stimulating factor. Blood tests revealed absence of antineutrophil antibodies, normal folate and B12 levels, moderate zinc deficiency and severe Vitamin B6 deficiency. Replacement therapy with oral Vitamin B6 restored blood vitamin levels to the normal range and corrected the neutropenia. Her cervical adenopathy regressed clinically and became negative on scintography following Vitamin B6 therapy and normalization of the blood neutrophil count. Conclusion Severe pyridoxine deficiency can lead to neutropenia. Screening for Vitamin B6 deficiency, along with folate and Vitamin B12 levels, is recommended in patients with refractory neutropenia, especially those with possible malabsorption syndromes, or a history of chronic-graft-versus host disease. Severe neutropenia may facilitate progression of squamous cell carcinoma.

    OBJECTIVE To determine the ideal method of surgical preoperative treatment for perforation with esophageal carcinoma.METHODS 36 cases of perforation with esophageal carcinoma were treated surgically in this series.Perforations occurred into the right lung in14 cases ,the mediastinum in 17 cases and trachea in 5 cases.Open thoracic surgery was performed in 34 cases,in which the right thoracic approach using a 3-incision method was applied in 16 cases,and operation by stages in 15 cases.Of the 34 cases,retrosternal substitution of the esophagus with stomach or colon was performed in 26 cases.RESULTS Surgery was successful in 31 cases and operative death occurred in 3 cases.The postoperative follow up study was from 3~72months.Of these cases 15 wree alive at 7~12 months, 2 at 24 months,and 1 at 72 months. The results can be considered satisfactory.CONCLUSION The therapeutic results of surgical treatment of perforation with esophageal carcinoma were markedly superior to that of conventional conservative treatment. The authors suggest that surgical intervention without delay should be undertaken for patients having a perforation with carcinoma of the esophagus. A right thoracic approach with a 3-incision method (retrosternal replacement of esophagus with stomach or colon) or operation by stages is preferable.

    2013-01-01

    Full Text Available Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm accounting for only 0.3-0.7% of all bladder tumors. Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.

  1. Safety and treatment patterns of multikinase inhibitors in patients with metastatic renal cell carcinoma at a tertiary oncology center in Italy

    International Nuclear Information System (INIS)

    Multikinase inhibitors (MKIs) sunitinib and sorafenib have become a standard of care for metastatic renal cell carcinoma (mRCC). This study assessed safety and treatment patterns for these agents in a real-world clinical practice setting in Italy. A retrospective medical record review was performed at a tertiary oncology center in Italy. The study included MKI-naïve non-trial patients ≥18 years old, with a histological diagnosis of mRCC, and who received sunitinib or sorafenib as first MKI during 9/2005-7/2008. Data were collected on adverse events (AEs), treatment modifications (discontinuations, interruptions, dose changes), and reasons for these modifications. 145 patients were included; 85 received sunitinib and 60 received sorafenib as first-line MKI. Median treatment duration was 6.6 (sunitinib) and 5.8 (sorafenib) months. 97.6% and 70.0% of patients receiving sunitinib and sorafenib, respectively, experienced ≥1 AE; 27.1% and 31.7% had ≥1 grade 3/4 AE. The most common any grade AE for sunitinib was fatigue/asthenia (81.2%), followed by mucositis/stomatitis (58.8%) and decreased taste sensation (42.4%), while for sorafenib this was fatigue/asthenia (43.3%) followed by hand-foot syndrome (38.3%) and diarrhea (31.7%). Treatment discontinuation, interruption, and dose reduction due to AEs occurred in 11.8%, 23.5%, and 30.6%, respectively, of patients receiving sunitinib, and 5.0%, 23.3%, and 36.7%, respectively, of patients receiving sorafenib. In this retrospective study, most patients experienced ≥1 AE during first-line MKI treatment. AEs were reported frequently and resulted in treatment modifications in 40% of patients receiving sunitinib and 45% of patients receiving sorafenib. These results suggest a need for additional effective and more tolerable treatments for mRCC

    2011-12-01

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

  3. A case repot of Merkel cell carcinoma on chronic lymphocytic leukemia: differential diagnosis of coexisting lymphadenopathy and indications for early aggressive treatment

    International Nuclear Information System (INIS)

    Chronic lymphocytic leukemia (CLL) is a monoclonal disorder, characterized by a progressive proliferation of functionally incompetent B lymphocytes. There is increased evidence of association between CLL and skin cancers, including the uncommon Merkel cell carcinoma (MCC). A case report of an 84-year old male, who presented with an aggressively recurrent form of MCC on the lower lip, on the background of an 8-year history of untreated CLL. During the recurrences of MCC, coexisting regional lymphadenopathy, posed a problem in the differential diagnosis and treatment of lymph node involvement. Histopathology and immunoistochemistry showed that submandibular lymphadenopathy coexisting with the second recurrence of MCC, was due to B-cell small lymphocytic lymphoma. The subsequent and more aggressive recurrence of the skin tumor had involved the superficial and deep cervical lymph nodes. Surgical excision followed by involved field radiation therapy has been proven effective for both malignancies. MCC has a high incidence of regional lymphadenopathy at presentation (12–45%) and even when it arises on the background of chronic leucemia, lymphadenopathy at presentation should be managed agressively with elective lymph node dissection. We overview the postulated correlation between Merkel tumor and CCL, the differential diagnosis of regional lymphadenopathy during the recurrences of the skin tumor and the strategies of treatment

  4. Budget impact analysis of first-line treatment with pazopanib for advanced renal cell carcinoma in Spain

    International Nuclear Information System (INIS)

    Due to economic constraints, cancer therapies are under close scrutiny by clinicians, pharmacists and payers alike. There is no published pharmacoeconomic evidence guiding the choice of first-line therapy for advanced renal cell carcinoma (RCC) in the Spanish setting. We aimed to develop a model describing the natural history of RCC that can be used in healthcare decision-making. We particularly analyzed the budget impact associated with the introduction of pazopanib compared to sunitinib under the Spanish National Healthcare System (NHS) perspective. We developed a Markov model to estimate the future number of cases of advanced RCC (patients with favorable or intermediate risk) resulting either from initial diagnosis or disease progression after surgery. The model parameters were obtained from the literature. We assumed that patients would receive either pazopanib or sunitinib as first-line therapy until disease progression. Pharmacological costs and costs associated with the management of adverse events (AE) were considered. A univariate sensitivity analysis was undertaken in order to test the robustness of the results. The model predicted an adult RCC prevalence of 7.5/100,000 (1-year), 20.7/100,000 (3-year) and 32.5/100,000 (5-year). These figures are very close to GLOBOCAN reported RCC prevalence estimates of 7.6/100,000, 20.2/100,000 and 31.1/100,000, respectively. The model predicts 1,591 advanced RCC patients with favorable or intermediate risk in Spain in 2013. Annual per patient pharmacological costs were €32,365 and €39,232 with pazopanib and sunitinib, respectively. Annual costs associated with the management of AE were €662 and €974, respectively. Overall annual per patient costs were €7,179 (18%) lower with pazopanib compared to sunitinib. For every point increase in the percentage of patients treated with pazopanib, the NHS would save €67,236. If all the 1,591 patients predicted were treated with pazopanib, the NHS would save €6

    Full Text Available Tumors of nail unit may be benign or malign. Different histological variants of subungual tumours have been reported. Subungual squamous cell carcinoma is rare, and the disease is often misdiagnosed as a benign condition, therefore it is difficult to estimate the real incidence of this disease. We hereby present a case of subungual squamous cell carcinoma that has previously been treated as leading to a delay in diagnosis and treatment. For this reason, the nail unit changes should be examined carefully and the diagnosis should be done with the histopathological examinations. Proper treatment should be planned according to the histopathological diagnosis.

  8. A comparative study of survival rates after treatment with induction chemotherapy or concurrent chemoradiotherapy in locoregionally advanced head and neck squamous cell carcinoma

    International Nuclear Information System (INIS)

    Since 1989 our treatment approach for head and neck squamous cell carcinoma (HNSCC) has involved comprehensive treatment with chemotherapy, radiation followed by surgery, if needed. Between 1989 and 2005 chemotherapy using fluorouracil and carboplatin div was administered as induction chemotherapy (ICT), and concurrent chemoradiotherapy (CCRT) was administered more recently between 2006 and 2011. In this study we compared the statistical difference in 3-year survival rates between the ICT group and CCRT group. The number of target patients was 137, all of which were previously untreated and suffered from locoregionally advanced HNSCC: 52 with Stage III, 78 with Stage IVA, 7 with Stage IVB. In the ICT and CCRT groups, 3-year cause-specific survival rates were 68.2% and 76.3% respectively, both of which were statistically not recessive compared to those in the other issues. Furthermore, the rate between the two groups was identified as significant for Stage III and not significant for Stage IV. In conclusion, the addition of new modalities for the treatment of far-advanced HNSCC should be mandatory. (author)

Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

  13. The Cost-Utility Analysis of PET-Scan in Diagnosis and Treatment of Non-Small Cell Lung Carcinoma in Iran

    International Nuclear Information System (INIS)

    PET scan is a non-invasive, complex and expensive medical imaging technology that is normally used for the diagnosis and treatment of various diseases including lung cancer. The purpose of this study is to assess the cost effectiveness of this technology in the diagnosis and treatment of non- small cell lung carcinoma (NSCLC) in Iran. The main electronic databases including The Cochrane Library and Medline were searched to identify available evidence about the performance and effectiveness of technology. A standard decision tree model with seven strategies was used to perform the economic evaluation. Retrieved studies and expert opinion were used to estimate the cost of each treatment strategy in Iran. The costs were divided into three categories including capital costs (depreciation costs of buildings and equipment), staff costs and other expenses (including cost of consumables, running and maintenance costs). The costs were estimated in both IR-Rials and US-Dollars with an exchange rate of 10.000 IR Rials per one US Dollar according to the exchange rate in 2008. The total annual running cost of a PET scan was about 8850 to 13000 million Rials, (0.9 to 1.3 million US$). The average cost of performing a PET scan varied between 3 and 4.5 million Rials (300 to 450US$). The strategies 3 (mediastinoscopy alone) and 7 (mediastinoscopy after PET scan) were more cost-effective than other strategies, especially when the result of the CT-scan performed before PET scan was negative. The technical performance of PET scan is significantly higher than similar technologies for staging and treatment of NSCLC. In addition, it might slightly improve the treatment process and lead to a small level of increase in the quality adjusted life year (QALY) gained by these patients making it cost-effective for the treatment of NSCLC

    Full Text Available Abstract Background Bladder small cell carcinoma is an uncommon tumour. Through a retrospective study we will present the evolution of recurrent and metastatic disease and outcome of patients treated at Léon-Bérard Cancer Centre. Methods Only 15 patients having recurrent or metastatic bladder small cell carcinoma were treated at Léon-Bérard Cancer Centre between 1996 and 2007. The patients were divided in two groups: a mixed small cell carcinoma group (9 patients and a pure small cell carcinoma group (6 patients. All the records and informations related to treatment and outcome of the 15 patients were retrospectively analyzed. Various characteristics of small cell carcinoma were investigated. Results The median age of the 15 patients having recurrent or metastatic bladder small cell carcinoma and treated at Léon-Bérard Cancer Centre was 63 years and the disease was at stage IV for all cases. Nine patients were treated by chemotherapy. Four patients were treated by local radiotherapy (3 with radiotherapy without previous surgery and 1 with surgery followed by radiotherapy and chemotherapy. One patient was treated by whole brain radiotherapy. And one patient died before treatment. After 52.4 months median follow up, 12 patients died. Median overall survival was 7.6 months. Survival probability at 1 year was 33%. Median overall survival was 9.9 months in the mixed small cell carcinoma group, and was only 4.6 months in the pure small cell carcinoma group. Survival probability at 1 year in the mixed small cell carcinoma group was 44% as compared to 17% in the pure small cell carcinoma group (Log-rank test: p = 0.228. Conclusion Recurrent and metastatic bladder small cell carcinoma is associated with very poor prognosis. The pure bladder small cell carcinoma appears to have poorer outcome than the mixed bladder small cell carcinoma. Chemotherapy using platinum drugs is a mainstay treatment.

    Small cell carcinoma of the gall bladder (SCCGB) is a rare condition, with only 53 prior cases reported in the world literature when our case was first diagnosed. Our patient was found to have limited stage disease and was treated with sequential laparoscopic cholecystectomy, etoposide/carboplatin chemotherapy followed by consolidating loco-regional radiation therapy. She is alive and well without evidence of disease more than 132 months since diagnosis. We describe here our experience in the diagnosis, staging workup, treatment, and surveillance of a case of SCCGB and review the published literature. Treated aggressively with currently available methods, patients with limited stage SCCGB can have an excellent prognosis. The authors' intent is to provide a reasonable plan of treatment for other physicians facing such an unusual patient. PMID:27197345

    Full Text Available The prognostic value of the Fuhrman renal-cell carcinoma (RCC gradation system has been supported by numerous studies. The high RCC  grade after Fuhrman is a sign of the high risk of recurrence even in patients with the early stages of the disease, in clear-cell tumor in par-  ticular. The anticancer vaccine Oncophage is recommended to prevent a recurrence and/or to increase a relapse-free period in patients with  early stages of RCC. While using this vaccine, one should follow the Fuhrman histological gradation system and use a coordinated multi-  disciplinary approach to treating this group of patients. This paper describes the Fuhrman histological gradation system, indications for the  use of Oncophage in patients with the early stages of ECC and a moderate risk of a recurrence. The role of urological surgeons, oncologists,  and pathomorphologists in the treatment of patients with early stages of ECC is also considered.

  13. Percutaneous radiofrequency ablation with transarterial embolization is useful for treatment of stage 1 renal cell carcinoma with surgical risk. Results at 2-year mean follow up

    International Nuclear Information System (INIS)

    Despite laparoscopic partial nephrectomy and laparoscopic cryotherapy being performed lately, an even less invasive treatment would be desirable in high-risk patients. Under local anesthesia with intravenous (i.v.) sedation, we were able to perform percutaneous radiofrequency ablation (RFA) combined with renal arterial embolization for unresectable stage 1 (T1NoMo) renal cell carcinoma (RCC). We evaluated the feasibility, safety and therapeutic effects of this technique after a 2-year mean follow up. Thirty-one patients who were not candidates for surgery underwent RFA for 36 stage 1 RCC. Twenty-eight tumors were percutaneously ablated 6 days after the tumor vessels were embolized. Dynamic contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) were performed to evaluate treatment at completion. Tumor enhancement was eliminated after two RFA sessions in all tumors. Thirty tumors remained free of enhancement during a mean follow-up period of 24.3 months. There were no major complications related to the procedures though one instance of pyonephrosis, two of subcapsular hematomas, one of retroperitoneal hemorrhage and one of nausea were seen after RFA. Two patients died of other diseases (id est (i.e.) colon cancer and cerebral bleeding) 20 and 26 months after RFA treatment. One patient had a local recurrence of tumor and underwent re-RFA. The recurrence rate of RCC after successful RFA was 2.8%. There was no recurrence in patients who had tumors of less than 4 cm after RFA at a mean follow-up period of 24.3 months. Local control was achieved in 100% of T1NoMo tumors including the recurrence case that underwent re-RFA. The result of the present study at 2-year mean follow up showed percutaneous RFA was a feasible, safe and promising therapy for the treatment of unresectable stage 1 RCC, especially those smaller than 4 cm.

    We report a case of a 73-year-old lady with transitional cell carcinoma and no evidence of metastatic disease presenting with gradual weight loss, pretibial swelling and painful weightbearing. Investigations revealed a lesion of the right tibial diaphysis. The radiological and clinical appearance was that of primary osteosarcoma. Biopsy results revealed metastatic transitional cell carcinoma of the tibia. Intramedullary nailing was performed which relieved pain on weightbearing. The patient declined radiotherapy and was started on a palliative care regimen. This case illustrates the importance of histological diagnosis in the treatment of diaphyseal lesions.

  18. CT staging of renal cell carcinoma

    International Nuclear Information System (INIS)

    Objective: To assess the usefulness of computerized tomography (CT) in the characterization of renal masses, in order to stage them, determine their prognosis and their appropriate clinical and/or surgical management. Material and Methods: Between 1988 and 2001, we selected 63 patients with renal tumors that had been examined by pathology. Patient's ages ranged from 16 to 88 years (25 women, 38 men). The studies were performed with a sequential helical CT, using 5 mm thickness sections every 5mm evaluating the cortico medullar and nephrographic phases. Renal tumors were characterized and staged without any knowledge about the pathological findings; subsequently the tomographic characteristics were compared to such findings. The following characteristics were evaluated: 1) mixed solid-cystic nature; 2) size; 3) borders; 4) enhancement; 5) necrosis; 6) hemorrhage; 7) central scar; 8) presence of fat; 9) collecting system; 10) capsular invasion; 11) perirenal fat invasion; 12) vessels; 13) Gerota's fascia; 14) lymph nodes; and 15) local and/or distant metastases. Results: Of the 63 tumors, 2 were complicated cysts; of the 61 remaining tumors, 10 were angiomyolipomas, 1 was a renal lymphoma, 1 was a focal xantogranulomatose pyelonephritis, 1 was a metanephric adenoma, 3 papillary renal cell carcinoma (RCC), 4 transitional cell tumors, 4 oncocytomas, 37 clear cell renal carcinoma. The CT could correctly characterize the 2 cystic tumors as such, as well as the 9 angiomyolipomas and the 4 transitional cell tumors. The 48 other tumors (1 angiomyolipoma, 1 lymphoma, 1 focal xantogranulomatose pyelonephritis, 1 metanephric adenoma, 3 papillary RCC, 4 oncocytomas, and 37 cell renal carcinomas) remaining were characterized as renal adenocarcinomas and CT staged. Conclusion: CT is a useful method to characterize renal masses since it determines their solid-cystic or fatty structure; aiding in many cases to define a surgical treatment. For the CT staging of renal tumors, the

  19. Results of concurrent radio-chemotherapy for the treatment of head and neck squamous cell carcinoma in everyday clinical practice with special reference to early mortality

    International Nuclear Information System (INIS)

    Randomized controlled trials have established concurrent chemo-radiotherapy as the preferred treatment option for inoperable local-regionally advanced head and neck squamous cell carcinomas (HNSCCs). Because many patients have multiple co-morbidities and would not fulfill the eligibility criteria of clinical trials, the results need to be re-evaluated in daily clinical practice with special reference to early mortality. 167 consecutive patients with HNSCC who received concurrent chemo-radiotherapy at the Basel University Hospital between 1988 and 2006 were analyzed retrospectively with a special focus on early deaths and risk factors for an unfavorable outcome. In our cohort, the 3- and 5-year overall survival rates were 54% and 47%, respectively. The therapy was associated with relevant toxicity and an early mortality rate of 5.4%. Patients dying early were analyzed individually for the cause of death. Patients with elevated white blood cell counts (HR: 2.66 p = 0,016) and vascular co-morbidities (HR: 5.3, p = 0,047) showed significantly worse survival rates. The same factors were associated with a trend toward increased treatment-related mortality. The 3-year survival rate improved from approximately 43% for patients treated before the year 2000 to 65% for patients treated after the year 2000 (Fisher’s exact test p = 0.01). Although many patients who received concurrent chemo-radiotherapy would not have qualified for clinical trials, the outcome was favorable and has significantly improved in recent years. However the early mortality was slightly worse than what is described in the literature

    Full Text Available Hashimoto’s thyroiditis, the most common autoimmune thyroid disease, is due to destruction of the thyroid gland by autoantibodies. Various types of thyroid malignancies may arise in Hashimoto’s thyroiditis. Follicular carcinomas, papillary carcinomas, lymphomas, medullary carcinomas and hurthle cell neoplasms may develop in Hashimoto’s thyroiditis. We present a rare case report of a 35-year-old female who presented with hypothyroidism of a two-year duration. A diagnosis of Hashimoto’s thyroiditis was made for which she was under treatment. Due to the recent increase in size of the thyroid, a fine needle aspiration cytology was done. A preoperative diagnosis of Hurthle cell neoplasm was made based on fine needle aspiration cytology findings. The total thyroidectomy specimen revealed Hashimoto’s thyroiditis with synchronous papillary carcinoma and Hurthle cell carcinoma, which is a very rare occurrence.

    Full Text Available Abstract Small cell carcinoma of the bladder (SCCB is rare, highly aggressive and diagnosed mainly at advanced stages. Hematuria is the main symptom of this malignancy. The origin of the disease is unknown; however the multipotent stem cell theory applies best to this case. Histology and immunohistochemistry shows a tumour which is indistinguishable from small cell lung carcinoma (SCLC. Coexistence of SCCB with other types of carcinoma is common. The staging system used is the TNM-staging of bladder transitional cell carcinoma. The treatment is extrapolated from that of SCLC. However, many patients with SCCB undergo radical resection which is rarely performed in SCLC. Patients with surgically resectable disease ( or = cT4bN+M+ should be managed with palliative chemotherapy based on neuroendocrine type regimens comprising a platinum drug (cisplatin in fit patients. The prognosis of the disease is poor mainly in the case of pure small cell carcinoma. Other research programs are needed to improve the outcome of SCCB.

    2014-06-01

    Full Text Available Basal cell carcinoma (BCC is the most frequent non-melanoma skin cancer. Only 5-15% of BCC cases can be found in patients aged 20-40 years (so-called early onset. The early onset BCC is characterized by active and aggressive tumour growth, clinically presenting in most of the cases as a morpheaform, locally infiltrating or recurrent BCC. Despite the advances in the study of the pathogenesis of this tumour, surgery remains the most used, most effective and most suitable treatment modality. We describe a case of a 39-year-old woman who developed an early onset BCC of the nasolabial fold. After the subsequent surgical excision an excellent cosmetic result was achieved.

  6. Squamous cell carcinoma complicating an hereditary epidermo-lysis bullosa

    International Nuclear Information System (INIS)

    The dystrophic form of hereditary epidermo-lysis bullosa is associated with an increased frequency of squamous cell carcinoma. We report a new case. An 18-year-old patient, carrying a Hallopeau Siemens hereditary epidermo-lysis bullosa, presented a subcutaneous nodular lesion, for 1 year that ulcerated and budded with inguinal lymphadenopathy. The histological study ted to the conclusion of a well differentiated squamous cell carcinoma. The patient was treated surgically. Tumor and metastatic lymph nodes were excised. A radiotherapy was decided but the postoperative course was fatal due to an infection and to a deterioration of her general condition. Squamous cell carcinoma frequently occurs on the cicatricial lesion of hereditary epidermo-lysis bullosa and usually affects males with recessive hereditary epidermo-lysis bullosa. Metastases are frequent, precocious and multiple. The treatment may be surgical. The particularities of our observation are the young age of patient and the localization. (author)

    Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors. Appropriate staging is important to determine appropriate treatment and has an impact on patient prognosis. Multimodality imaging is usually needed, and there is no consensus on the optimal imaging strategy. The purpose of this article is to review various aspects of Merkel cell carcinoma imaging and look in detail at how optimal multimodality staging should be carried out. (orig.)

  8. Thyroid size change by CT monitoring after sorafenib or sunitinib treatment in patients with renal cell carcinoma: Comparison with thyroid function

    International Nuclear Information System (INIS)

    Objective: Hypothyroidism is a common complication in patients receiving tyrosine kinase inhibitors. We evaluated the relationship between thyroid size evident on CT and thyroid function in patients with advanced renal cell carcinoma (RCC) receiving tyrosine kinase inhibitors. Materials and methods: Forty-two patients with metastatic RCC receiving tyrosine kinase inhibitors (sorafenib n = 25; sunitinib n = 17) and, followed-up for ≥12 months were eligible. Patients who had ever shown an elevated thyroid-stimulating hormone (TSH) level of >10 mU/l were defined as having “hypothyroidism”. CT scans were performed before, and 3, 6, 9, and 12 months after the start of treatment. The area of the thyroid in the maximum section at each examination was measured and compared with that before treatment. Using repeated-measures ANOVA, differences in thyroid size were compared over time between patients with and without “hypothyroidism”, in relation to the type of drug employed. Results: Twenty-one patients (sorafenib 9, sunitinib 12) developed “hypothyroidism” 95 ± 88 days (range 12–315 days) after the start of treatment. In such patients, the thyroid was reduced in size to 89 ± 16% after 3 months, 81 ± 21% after 6 months, 71 ± 21% after 9 months and 68 ± 21% after 12 months, whereas the patients without “hypothyroidism” maintained a thyroid size of 90 ± 12% even after 12 months (p = 0.0030). Among the patients with “hypothyroidism”, those treated with sunitinib tended to show greater thyroid size reduction than those with sorafenib (59 ± 23% vs. 79 ± 13%, after 12 months). Conclusion: Tyrosine kinase inhibitors cause an apparent thyroid size reduction in patients with “hypothyroidism”

    Objective: Hypothyroidism is a common complication in patients receiving tyrosine kinase inhibitors. We evaluated the relationship between thyroid size evident on CT and thyroid function in patients with advanced renal cell carcinoma (RCC) receiving tyrosine kinase inhibitors. Materials and methods: Forty-two patients with metastatic RCC receiving tyrosine kinase inhibitors (sorafenib n = 25; sunitinib n = 17) and, followed-up for ≥12 months were eligible. Patients who had ever shown an elevated thyroid-stimulating hormone (TSH) level of >10 mU/l were defined as having “hypothyroidism”. CT scans were performed before, and 3, 6, 9, and 12 months after the start of treatment. The area of the thyroid in the maximum section at each examination was measured and compared with that before treatment. Using repeated-measures ANOVA, differences in thyroid size were compared over time between patients with and without “hypothyroidism”, in relation to the type of drug employed. Results: Twenty-one patients (sorafenib 9, sunitinib 12) developed “hypothyroidism” 95 ± 88 days (range 12–315 days) after the start of treatment. In such patients, the thyroid was reduced in size to 89 ± 16% after 3 months, 81 ± 21% after 6 months, 71 ± 21% after 9 months and 68 ± 21% after 12 months, whereas the patients without “hypothyroidism” maintained a thyroid size of 90 ± 12% even after 12 months (p = 0.0030). Among the patients with “hypothyroidism”, those treated with sunitinib tended to show greater thyroid size reduction than those with sorafenib (59 ± 23% vs. 79 ± 13%, after 12 months). Conclusion: Tyrosine kinase inhibitors cause an apparent thyroid size reduction in patients with “hypothyroidism”.

  10. SU-E-T-275: Radiobiological Evaluation of Intensity Modulated Radiotherapy Treatment for Locally Advanced Head and Neck Squamous Cell Carcinomas

    International Nuclear Information System (INIS)

    Purpose: To evaluate the radiobiological outcome of Intensity Modulated Radiotherapy Treatment (IMRT) for locally advanced head and neck squamous cell carcinomas using HART (Histogram Analysis in Radiation Therapy; J Appl Clin Med Phys 11(1): 137–157, 2010) program and compare with the clinical outcomes. Methods: We have treated 20 patients of stage III and IV HNSCC Oropharynx and hypopharynx with accelerated IMRT technique and concurrent chemotherapy. Delineation of tumor and normal tissues were done using Danish Head and Neck Cancer Group (DAHANCA) contouring guidelines and radiotherapy was delivered to a dose of 70Gy in 35 fractions to the primary and involved lymph nodes, 63Gy to intermediate risk areas and 56 Gy to lower risk areas, Monday to Saturday, 6 Days/week using 6 MV Photons with an expected overall treatment time of 6 weeks. The TCP and NTCP's were calculated from the dose-volume histogram (DVH) statistics using the Poisson Statistics (PS) and JT Lyman models respectively and the Resultwas correlated with clinical outcomes of the patients with mean follow up of 24 months. Results: Using HART program, the TCP (0.89± 0.01) of primary tumor and the NTCP for parotids (0.20±0.12), spinal cord (0.05±0.01), esophagus (0.30±0.2), mandible (0.35±0.21), Oral cavity (0.37±0.18), Larynx (0.30±0.15) were estimated and correlated with clinical outcome of the patients. Conclusion: Accelerated IMRT with Chemotherapy is a clinical feasible option in the treatment of locally advanced HNSCC with encouraging initial tumour response and acceptable acute toxicities. The correlation between the clinical outcomes and radiobiological model estimated parameters using HART programs are found to be satisfactory

    Full Text Available To report on a suspected case of idiopathic radiation recall dermatitis in an individual nine months after radiation and chemotherapy treatment of squamous cell carcinoma of the right tonsil. Radiation recall dermatitis is the development of a reaction in a previously irradiated area of skin after the administration of an aggravating medication. A review of the literature revealed several cases of radiation recall dermatitis that occur following radiation therapy and the institution of chemotherapy. Other medications have also been implicated in radiation recall dermatitis; however, this patient has not started any new medications since completion of his combined therapy. The patient developed this skin reaction in a distribution pattern identical to the area that received the highest radiation dose suggesting a possible link between radiation recall dermatitis and radiation dose. Radiation recall dermatitis is a reaction that is typically seen shortly after the reinstitution of chemotherapy during radiation therapy. This case illustrates that other medical etiologies are possible and suggests a relationship between radiation recall dermatitis and the total radiation dose an area receives.

    Full Text Available Abstract Background Primary squamous cell carcinomas of the colorectum are very uncommon. Until now, to the best of our knowledge, only 114 cases of squamous cell carcinoma in the colorectum exist in the reported literature. Here we report a case of squamous cell carcinoma of the rectum in the ethnic Kashmiri population in northern India. Case Presentation The case of a 60-year-old male patient (Asian with a pure squamous cell carcinoma of the rectum is presented here. The patient underwent a curative surgery with concomitant chemotherapy. Two years after the initial curative resection of the tumor he is still alive. Conclusion The prognosis for squamous cell carcinoma of the colorectum is worse than for that of adenocarcinoma, because of the delayed diagnosis. The etiopathogenicity of squamous cell carcinoma of the colorectum is discussed. Surgical resection of the lesion seems to be the treatment of choice. Chemotherapy also helps in improvement of the prognosis.

  14. Bone Metastasis from Renal Cell Carcinoma

    About one-third of patients with advanced renal cell carcinoma (RCC) have bone metastasis that are often osteolytic and cause substantial morbidity, such as pain, pathologic fracture, spinal cord compression and hypercalcemia. The presence of bone metastasis in RCC is also associated with poor prognosis. Bone-targeted treatment using bisphosphonate and denosumab can reduce skeletal complications in RCC, but does not cure the disease or improve survival. Elucidating the molecular mechanisms of tumor-induced changes in the bone microenvironment is needed to develop effective treatment. The “vicious cycle” hypothesis has been used to describe how tumor cells interact with the bone microenvironment to drive bone destruction and tumor growth. Tumor cells secrete factors like parathyroid hormone-related peptide, transforming growth factor-β and vascular endothelial growth factor, which stimulate osteoblasts and increase the production of the receptor activator of nuclear factor κB ligand (RANKL). In turn, the overexpression of RANKL leads to increased osteoclast formation, activation and survival, thereby enhancing bone resorption. This review presents a general survey on bone metastasis in RCC by natural history, interaction among the immune system, bone and tumor, molecular mechanisms, bone turnover markers, therapies and healthcare burden.

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

    Full Text Available The current standard of care for metastatic urothelial carcinoma (UC is cisplatin-based chemotherapy but treatment is generally not curative. Mechanisms of resistance to conventional cytotoxic regimens include tumor cell drug efflux pumps, intracellular anti-oxidants and enhanced anti-apoptotic signaling. Blockade of signaling pathways with small molecule tyrosine kinase inhibitors has produced dramatic responses in subsets of other cancers. Multiple potential signaling pathway targets are altered in UC. Blockade of the PI3K/Akt/mTOR pathway may prove efficacious because 21% have activating PI3K mutations and another 30% have PTEN inactivation (which leads to activation of this pathway. The fibroblast growth factor receptor 3 protein may be overactive in 50-60% and agents which block this pathway are under active development. Blockade of multiple other pathways including HER2 and aurora kinase also have potential efficacy. Anti-angiogenic and immunotherapy strategies are also under development in UC and are discussed in this review. Novel therapeutic approaches are needed in UC. We review the various strategies under development in this disease and discuss how best to evaluate and optimize their efficacy.

  17. Curative treatment of oesophageal carcinoma: current options and future developments

    International Nuclear Information System (INIS)

    Since the 1980s major advances in surgery, radiotherapy and chemotherapy have established multimodal approaches as curative treatment options for oesophageal cancer. In addition the introduction of functional imaging modalities such as PET-CT created new opportunities for a more adequate patient selection and therapy response assessment. The majority of oesophageal carcinomas are represented by two histologies: squamous cell carcinoma and adenocarcinoma. In recent years an epidemiological shift towards the latter was observed. From a surgical point of view, adenocarcinomas, which are usually located in the distal third of the oesophagus, may be treated with a transhiatal resection, whereas squamous cell carcinomas, which are typically found in the middle and the upper third, require a transthoracic approach. Since overall survival after surgery alone is poor, multimodality approaches have been developed. At least for patients with locally advanced tumors, surgery alone can no longer be advocated as routine treatment. Nowadays, scientific interest is focused on tumor response to induction radiochemotherapy. A neoadjuvant approach includes the early and accurate assessment of clinical response, optimally performed by repeated PET-CT imaging and endoscopic ultrasound, which may permit early adaption of the therapeutic concept. Patients with SCC that show clinical response by PET CT are considered to have a better prognosis, regardless of whether surgery will be performed or not. In non-responding patients salvage surgery improves survival, especially if complete resection is achieved

  2. Postoperative Intensity-Modulated Radiotherapy for Squamous Cell Carcinoma of the External Auditory Canal and Middle Ear: Treatment Outcomes, Marginal Misses, and Perspective on Target Delineation

    International Nuclear Information System (INIS)

    Purpose: To report outcomes of the rare disease of squamous cell carcinoma (SCC) of the external auditory canal (EAC) and middle ear treated with surgery and postoperative intensity-modulated radiotherapy (IMRT). Failure patterns related to spatial dose distribution were also analyzed to provide insight into target delineation. Methods and Materials: A retrospective review was conducted of the records of 11 consecutive patients with SCC of the EAC and middle ear who were treated with curative surgery and postoperative IMRT at one institution between January 2007 and February 2010. The prescribed IMRT dose was 60 to 66 Gy at 2 Gy per fraction. Three patients also received concurrent cisplatin-based chemotherapy, and 1 patient received concurrent oral tegafur/uracil. The median follow-up time was 19 months (range, 6–33 months). Results: Four patients had locoregional recurrence, yielding an estimated 2-year locoregional control rate of 70.7%. Among them, 1 patient had persistent disease after treatment, and 3 had marginal recurrence. Distant metastasis occurred in 1 patient after extensive locoregional recurrence, yielding an estimated 2-year distant control rate of 85.7%. The estimated 2-year overall survival was 67.5%. The three cases of marginal recurrence were near the preauricular space and glenoid fossa of the temporomandibular joint, adjacent to the apex of the ear canal and glenoid fossa of the temporomandibular joint, and in the postauricular subcutaneous area and ipsilateral parotid nodes, respectively. Conclusions: Marginal misses should be recognized to improve target delineation. When treating SCC of the EAC and middle ear, care should be taken to cover the glenoid fossa of the temporomandibular joint and periauricular soft tissue. Elective ipsilateral parotid irradiation should be considered. The treatment planning procedure should also be refined to balance subcutaneous soft-tissue dosimetry and toxicity.

  3. Concurrent intra-arterial carboplatin administration and radiation therapy for the treatment of advanced head and neck squamous cell carcinoma: short term results

    International Nuclear Information System (INIS)

    The aim of the present study was to evaluate the survival, efficacy and safety of a modified RADPLAT-like protocol using carboplatin instead of cisplatin. Fifty-six patients with primary head and neck squamous cell carcinoma received 4 cycles of intra-arterial carboplatin (350 mg/m2 per cycle every 2 weeks), with concurrent three-dimensional conformal radiation therapy. Two major and 4 minor complications were observed. Forty-five of the 56 patients (80%) completed the protocol, while 11 (20%) patients had to discontinue the intra-arterial infusions due to the occurrence of severe haematological toxicity, but were able to complete radiotherapy. Forty-four (98%) of the 45 patients who completed the protocol and 10 (91%) of the 11 who did not, were free of disease at the end of the treatment, for a comprehensive 96% of CR overall. After a median 23.55 months (range: 2 to 58 months) of follow-up, 40 patients (71%) are alive and disease-free, 1 (2%) is alive but affected by disease and 15 (27%) have died of the disease or other causes. Intra-arterial carboplatin administration with concurrent three-dimensional conformal radiation therapy seems to be a promising alternative to RADPLAT in the treatment of advanced head and neck tumours. Haematological and non-haematological toxicities are virtually similar, but carboplatin has the advantage in that it is not nephrotoxic and can be used at very high doses without any significant increase in the extent of side effects

  5. Stages III and IV squamous cell carcinoma of the mouth: Three-year experience with superselective intraarterial chemotherapy using cisplatin prior to definitive treatment

    International Nuclear Information System (INIS)

    Purpose: This study was designed to assess the 3-year experience with superselective intraarterial chemotherapy prior to definitive treatment for stages III and IV squamous cell carcinomas of the mouth.Methods: Twenty-two patients prospectively received superselective intraarterial chemotherapy using relatively low-dose cisplatin via a transfemoral approach. The locations of the tumors were the tongue (n=12), gingiva (n=5), buccal mucosa (n=2), hard palate (n=1), floor of the mouth (n=1), and lip (n=1). After intraarterial chemotherapy, 21 patients underwent surgery (n=14), radiation therapy (n=6), or both (n=1). The survival rate of 25 patients who underwent surgery with/without radiationtherapy until 1992 at Kumamoto University Hospital was also evaluated as a historical control. The survival curve was calculated with the Kaplan-Meier method, and the statistical difference between survival curves was determined with the generalized Wilcoxon test.Results: The overall response rate was 95% [complete response (tumor completely resolved), 24%; partial response (tumor reduction ≥50%), 71%]. Fifty-two intraarterial infusions were performed without any catheter-related complications. Mild and transient local toxicity such as edema or mucositis of the infused area was relatively common. One patient died of renal failure from cisplatin. After a median follow-up of 20 months (range 2-41 months), the estimated 3-year survival rate for patients who underwent intraarterial chemotherapy plus surgery was 91%. The survival of the patients who underwent intraarterial chemotherapy plus surgery tended to be longer than that of the historical control.Conclusions: Early tumor reduction without delay of subsequent treatments can be obtained by intraarterial chemotherapy while minimizing complications and possibly improving survival. Further investigations of long-term survival with larger series need to be performed.

  6. Treatment Results of Postoperative Radiotherapy on Squamous Cell Carcinoma of the Oral Cavity: Coexistence of Multiple Minor Risk Factors Results in Higher Recurrence Rates

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to investigate the treatment results of postoperative radiotherapy (PORT) on squamous cell carcinoma of the oral cavity (OSCC). Materials and Methods: This study included 302 OSCC patients who were treated by radical surgery and PORT. Indications for PORT include Stage III or IV OSCC according to the 2002 criteria of the American Joint Committee on Cancer, the presence of perineural invasion or lymphatic invasion, the depth of tumor invasion, or a close surgical margin. Patients with major risk factors, such as multiple nodal metastases, a positive surgical margin, or extracapsular spreading, were excluded. The prescribed dose of PORT ranged from 59.4 to 66.6Gy (median, 63Gy). Results: The 3-year overall and recurrence-free survival rates were 73% and 70%, respectively. Univariate analysis revealed that differentiation, perineural invasion, lymphatic invasion, bone invasion, location (hard palate and retromolar trigone), invasion depths ≥10mm, and margin distances ≤4mm were significant prognostic factors. The presence of multiple significant factors of univariate analysis correlated with disease recurrence. The 3-year recurrence-free survival rates were 82%, 76%, and 45% for patients with no risk factors, one or two risk factors, and three or more risk factors, respectively. After multivariate analysis, the number of risk factors and lymphatic invasion were significant prognostic factors. Conclusion: PORT may be an adequate adjuvant therapy for OSCC patients with one or two risk factors of recurrence. The presence of multiple risk factors and lymphatic invasion correlated with poor prognosis, and more aggressive treatment may need to be considered.

The local control rate was assessed in front of stage, surgical margins and postoperative radiotherapy. Results: local recurrences were diagnosed in 28 (38%) patients. Only T stage and lymph node metastases were related to recurrences in the primary site. Control of disease in the primary site was achieved in 80% of pn patients and postoperative radiotherapy didn't show any effect in this group. Conclusion: advanced local disease without lymph node metastases can be treated with surgery only. (author)

    Full Text Available Circulating tumor cells (CTCs are those cells present in the blood and have antigenic and/or genetic characteristics of a specific tumor type. CTCs can be detected in the peripheral blood of cancer patients. Various techniques are available for detection of CTCs, which provide evidence for future metastasis. CTCs may provide new insight into the biology of cancer and process of metastasis in oral squamous cell carcinoma (OSCC. The detection of CTCs may represent a new diagnostic tool for predicting the occurrence of metastatic disease in OSCC and endow with the treatment strategies to efficiently treat and prevent cancer metastasis. This review gives an insight into the significance of CTCs and different techniques for detection of CTCs.

    Full Text Available A select group of patients with upper tract urothelial carcinoma may be appropriate candidates for minimally invasive management. Organ-preserving endoscopic procedures may be appropriate for patients with an inability to tolerate major surgery, solitary kidney, bilateral disease, poor renal function, small tumor burden, low-grade disease, or carcinoma in situ. We review the published literature on the use of topical treatment for upper tract urothelial carcinoma and provide our approach to treatment in the office setting.

  11. Clear cell carcinoma of the endometrium: an uncommon entity with a favorable prognosis

    International Nuclear Information System (INIS)

    From 1969 to 1978, 345 patients with endometrial carcinoma were treated at the Medical College of Virginia. Twenty-three of these were clear cell carcinoma (6.6%). Previous reports indicate a poor prognosis with this histological entity. In this series no differences were noticed between clear cell carcinoma and classical adenocarcinoma with regard to variables such as age, race, stage at presentation or response to treatment. Clear cell carcinoma is a distinct histological entity and does not appear to be different than classical adenocarcinoma in its behavior and response to therapy. It is recommended that these tumors be managed by a combination of surgery and radiotherapy

  12. Renal Preservation Therapy for Renal Cell Carcinoma

    Full Text Available Renal preservation therapy has been a promising concept for the treatment of localized renal cell carcinoma (RCC for 20 years. Nowadays partial nephrectomy (PN is well accepted to treat the localized RCC and the oncological control is proved to be the same as the radical nephrectomy (RN. Under the result of well oncological control, minimal invasive method gains more popularity than the open PN, like laparoscopic partial nephrectomy (LPN and robot assisted laparoscopic partial nephrectomy (RPN. On the other hand, thermoablative therapy and cryoablation also play an important role in the renal preservation therapy to improve the patient procedural tolerance. Novel modalities, but limited to small number of patients, include high-intensity ultrasound (HIFU, radiosurgery, microwave therapy (MWT, laser interstitial thermal therapy (LITT, and pulsed cavitational ultrasound (PCU. Although initial results are encouraging, their real clinical roles are still under evaluation. On the other hand, active surveillance (AS has also been advocated by some for patients who are unfit for surgery. It is reasonable to choose the best therapeutic method among varieties of treatment modalities according to patients' age, physical status, and financial aid to maximize the treatment effect among cancer control, patient morbidity, and preservation of renal function.

    Renal cell carcinoma (RCC) is one of the ten most frequent solid tumors worldwide. Recent innovations in the treatment of metastatic disease have led to new therapeutic approaches being investigated in the adjuvant setting. Observation is the only current standard of care after radical nephrectomy, although there is evidence of efficacy of adjuvant use of vaccine among all the strategies used. This article aims to collect published experiences with systemic adjuvant approaches in RCC and to describe the results of past and ongoing phase III clinical trials in this field. We explored all the systemic treatments, including chemotherapy, immunotherapy and targeted drugs while alternative approaches have also been described. Appropriate selection of patients who would benefit from adjuvant therapies remains a crucial dilemma. Although the international guidelines do not actually recommend any adjuvant treatment after radical surgery for RCC, no conclusions have yet been drawn pending the results of the promising ongoing clinical trials with the target therapies. The significant changes that these new drugs have made on advanced disease outcome could represent the key to innovation in terms of preventing recurrence, delaying relapse and prolonging survival after radical surgery for RCC.

El aumento de supervivencia observado en pacientes con carcinoma renal metastásico tras la realización de nefrectomía, rompe un concepto clásico de la oncología según el cual la extirpación del tumor primario en tumores avanzados carece de sentido. Junto con el melanoma, es el único tumor en el que tratamientos inmunomoduladores, como interleukina-2 producen un beneficio clínico al paciente. El tratamiento del cáncer renal metastásico con interleukina-2 intravenosa a dosis altas ha confirmado en estudios aleatorios que puede producir respuestas completas de muy larga duración, en la práctica equivalentes a la curación. Por último, el cáncer renal está siendo empleado como modelo clínico para demostrar la eficacia de múltiples tratamientos dirigidos frente a nuevas dianas. En la actualidad se están estudiando más de 30 nuevos fármacos como tratamiento del cáncer renal, habiendo sido el primer tumor en el que se ha demostrado el beneficio clínico del tratamiento con inhibidores de la angiogénesis. En este artículo se revisan los aspectos más relevantes sobre el cáncer renal, incluyendo epidemiología, factores pronósticos, presentación clínica; bases moleculares y el estado actual de desarrollo de varios de los múltiples fármacos que se están estudiando en esta enfermedad.Renal cell carcinoma presents several unique features, which distinguish it from other tumours. The increase in survival that has been described in patients with renal cell carcinoma following nephrectomy breaks a classical rule of oncology, which states that surgery of the primary tumour has no role in the treatment of patients with advanced disease.

    Advances in surgical and medical treatments for ovarian cancer have improved prognoses. Platinum drugs in particular are pivotal for the medical treatment of ovarian cancer. However, previous studies have revealed that some histological subtypes, such as clear cell carcinoma, are resistant to medical treatment, including that with platinum drugs. Consequently, the clinical prognosis of advanced clear cell carcinoma is remarkably inferior, primarily because of its chemoresistant behavior. The ...

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of pazopanib hydrochloride (GlaxoSmithKline) to submit evidence of the clinical and cost effectiveness of the drug for the first-line treatment of advanced and/or metastatic renal cell carcinoma, as part of the Institute's single technology appraisal (STA) process. The Aberdeen Health Technology Assessment Group were commissioned to act as the Evidence Review Group (ERG). This article provides a description of the company submission, the ERG review and NICE's subsequent decisions. The objective of this paper is to summarize the independent review and critique of the evidence submitted for the consideration of the NICE Appraisal Committee and NICE's subsequently issued guidance. The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology based upon the manufacturer's submission to NICE. The ERG also independently searched for relevant evidence and modified the manufacturer's decision analytic model to examine the impact of altering some of the key assumptions. For progression-free survival (PFS), there was a statistically significant longer survival for pazopanib compared with placebo (as assessed by the ERG, based upon the original manufacturer submission with a clinical cut-off date of 23 May 2008) [median 11.1 vs. 2.8 months; hazard ratio (HR) 0.40; 95 % CI 0.27, 0.60]. Data from the indirect comparison suggested that pazopanib had a greater survival than interferon alpha (IFN-α) [HR 0.512; 95 % CI 0.326, 0.802] but provided no evidence of any difference compared with sunitinib (HR 0.949; 95 % CI 0.575, 1.568). With regard to overall survival, 64 % (n = 99) of patients in the pazopanib arm and 63 % (n = 49) of patients in the placebo arm had died and a total of 51 % (n = 40) of placebo patients had crossed over to receive pazopanib.

Three kinds ofcytoskeleton perturbing agents, colchiclnes (Col),cytochalssin D (CD) and vinblastine (VBL), were used totreat HCC cells and hepatocytes and the effects of thesetreatent on cell viscoelastic coefficients were investigated.The experimental results were analyzed with a thres-elsmentstandard linear solid. Further, the viscoelastic properties ofHTC cells and the adhesion force of different cycle HTC cellswere also investigated. The synchronous G1 and S phasecells were achieved through thymine-2-desoryriboside andcolchicines sequential blockage method and thymine-2-desoryriboside blockage method respectively.RESULTS: The elastic coefficients, but not viscouscoefficient of HCC cells (k1 = 103.6± 12.6N.m-2, k2 =42.5±10.4N. m-2, μ = 4.5 ± 1.9Pa. s), were significantly higherthan the corresponding value for hepatocytes (K1 = 87.5 ±12.1N.m-2, k2 =33.3± 10.3N.m-2, μ=5.9±3.0Pa. s, P<0.01). Upon treatment with CD, the viscoelastic coefficients ofboth hepotocytes and HCC cells decreased consistently,with magnitudes for the decrease in elastic coefficients ofHCC cells (k1: 68.7 N.m-2 to 81.7N.m-2, 66.3 % to 78.9 %;k2: 34.5 N.m-2 to37.1N.m-2, 81.2% to 87.3 %, P<0.001)larger than those for normal hepatocytes (k1: 42.6N. m-2 to49.8N.nt-2, 48.7% to56.9 %; k2: 17.2N.m-2 to 20.4N.m-2,51.7 % to 61.3 %, P< 0.001).

  9. Concomitant chemoradiotherapy versus induction chemotherapy followed by chemoradiotherapy as definitive, first line treatment of squamous cell carcinoma of the head and neck. A retrospective single center analysis

    International Nuclear Information System (INIS)

    Despite the lack of evidence to support its implementation in the clinical practice, induction chemotherapy (IC) before chemoradiotherapy (CRT) is often used in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). We retrospectively examined the tolerability, feasibility, and clinical outcome of both concepts in a single center analysis. In all, 83 patients were treated between 2007 and 2010 with IC + CRT (n = 42) or CRT alone (n = 41). IC consisted of docetaxel, cisplatin and 5-fluorouracil (TPF), or cisplatin and 5-fluorouracil (PF). All patients were scheduled to receive 2 cycles of PF during concurrent CRT. Adverse events were assessed according to the common toxicity criteria of adverse events (CTCAE v. 3.0). Associations were tested using the χ2 test, and survival estimates were calculated according to Kaplan-Meier. The median follow-up was 30.35 months (range 2.66-61.25 months). At 2 years, the overall survival rate was significantly higher for primary CRT compared to IC + CRT group (74.8 % vs. 54 %, respectively; p = 0.041). Significantly more treatment-related overall grade 4 toxicities were documented in the IC + CRT group compared to the CRT group (42.9% vs. 9.8%; p = 0.001). Renal toxicity ≥ grade 2 occurred in 52.4 % vs. 7.3 % (p < 0.001), respectively. In all, 93 % of the patients with primary CRT compared to 71 % with IC + CRT received the planned full radiotherapy dose (p = 0.012). This is, to our knowledge, the largest retrospective study to compare IC + CRT with primary CRT. IC showed high acute toxicity, compromised the feasibility of concurrent CRT, and was associated with reduced overall survival rates compared to primary CRT. The lack of clinical benefit in conjunction with the increased toxicity does not support implementation of IC. (orig.)

    Full Text Available Patients with brain metastasis from renal cell carcinoma (RCC or melanoma have historically had very poor prognoses of less than one year. Stereotactic radiosurgery (SRS can be an effective treatment for patients with these tumors. This study analyzes the effect of pretreatment prognostic factors on overall survival (OS for RCC and melanoma patients with metastasis to the brain treated with SRS. A total of 122 patients with brain metastases from either RCC or melanoma were grouped by age at brain metastasis diagnosis, whether they received whole brain radiation therapy (WBRT in addition to SRS, or they underwent surgical resection, Karnofsky Performance Score (KPS, number of brain metastases, and primary tumor. Median survival times for melanoma patients and RCC patients were 8.20 ± 3.06 and 12.70 ± 2.63 months, respectively. Patients with >5 metastases had a significantly shorter median survival time (6.60 ± 2.45 months than the reference group (1 metastasis, 10.70 ± 13.40 months, p = 0.024. Patients with KPS ≤ 60 experienced significantly shorter survival than the reference group (KPS = 90–100, with median survival times of 5.80 ± 2.46 months (p < 0.001 and 45.20 ± 43.52 months, respectively. We found a median overall survival time of 12.7 and 8.2 months for RCC and melanoma, respectively. Our study determined that a higher number of brain metastases (>5 and lower KPS were statistically significant predictors of a lower OS prognosis.

    The formation of renal cell carcinoma (RCC) is a complicated process including a large number of gene modifications. There are two key mechanisms in this process; ①Genetics of RCC-mutation formation by means of DNA nucleotide sequences alteration ;②Epigenetics of RCC-the levels of genes change through base modification without DNA nucleotide sequences alteration. As the major member of epigenetic family, abnormal DNA methylation can induce the RCC occurrence through influencing the transcription of RCC associated genes. Now we summarizes the roles of DNA methylation in clinical diagnosis, treatment, prognosis and pathologic staging of RCC.%肾癌的发生与形成是多基因改变的复杂过程,而参与其中的机制主要有2类:①遗传学机制,即通过DNA核苷酸序列改变而形成突变,引起肿瘤形成;②表观遗传学机制,即在DNA核苷酸序列不变的情况下,通过碱基修饰而引起基因水平的变化.作为表观遗传学家族中的重要成员,DNA甲基化程度的异常变化可影响肾癌相关基因的转录,从而影响肾癌的发生.现对DNA甲基化在肾细胞癌中的早期诊断、治疗靶点、预后监测和病理分期等临床应用作一综述.

    Fifteen patients with inoperable squamous cell carcinoma of the vulva were treated with Bleomycin and irradiation. Only 2 patients were also treated with vulvectomy and bilateral lymphadenectomy 2 weeks later. One patient survived more than 4 years without signs of recurrence, another survived 2 1/2 years and 2 more 18 and 12 months respectively. The rest died less than 6 months after the treatment. Three patients developed signs of lung fibrosis. Bleomycin and irradiation may render a tumor operable, but in most cases this regime merely aims at palliation.

    Immunotherapy has long played a role in urothelial cancers with the use of bacille Calmette Guérin (BCG) being a mainstay in the treatment of nonmuscle invasive bladder cancer. Novel therapeutic approaches have not significantly impacted mortality in this population and so a renaissance in immunotherapy has resulted. This includes recombinant BCG, oncolytic viruses, monoclonal antibodies, vaccines, and adoptive T-cell therapy. Herein, we provide a review of the current state of the art and future therapies regarding immunotherapeutic strategies for urothelial carcinoma. PMID:27247630

    Full Text Available BACKGROUND: Accurate detection and analysis of circulating tumor cells plays an important role in the diagnosis and treatment of metastatic cancer treatment. METHODS AND FINDINGS: A cell microarray chip was used to detect spiked carcinoma cells among leukocytes. The chip, with 20,944 microchambers (105 µm width and 50 µm depth, was made from polystyrene; and the formation of monolayers of leukocytes in the microchambers was observed. Cultured human T lymphoblastoid leukemia (CCRF-CEM cells were used to examine the potential of the cell microarray chip for the detection of spiked carcinoma cells. A T lymphoblastoid leukemia suspension was dispersed on the chip surface, followed by 15 min standing to allow the leukocytes to settle down into the microchambers. Approximately 29 leukocytes were found in each microchamber when about 600,000 leukocytes in total were dispersed onto a cell microarray chip. Similarly, when leukocytes isolated from human whole blood were used, approximately 89 leukocytes entered each microchamber when about 1,800,000 leukocytes in total were placed onto the cell microarray chip. After washing the chip surface, PE-labeled anti-cytokeratin monoclonal antibody and APC-labeled anti-CD326 (EpCAM monoclonal antibody solution were dispersed onto the chip surface and allowed to react for 15 min; and then a microarray scanner was employed to detect any fluorescence-positive cells within 20 min. In the experiments using spiked carcinoma cells (NCI-H1650, 0.01 to 0.0001%, accurate detection of carcinoma cells was achieved with PE-labeled anti-cytokeratin monoclonal antibody. Furthermore, verification of carcinoma cells in the microchambers was performed by double staining with the above monoclonal antibodies. CONCLUSION: The potential application of the cell microarray chip for the detection of CTCs was shown, thus demonstrating accurate detection by double staining for cytokeratin and EpCAM at the single carcinoma cell level.

    The traditional view that adult human liver tumors, mainly hepatocellular carcinoma (HCC), arise from mature cell types has been challenged in recent dec-ades. The results of several studies suggest that HCC can be derived from liver stem cells. There are four levels of cells in the liver stem cell lineage: hepatocytes, hepatic stem cells/oval cells, bone marrow stem cells and hepato-pancreas stem cells. However, whether HCC is resulted from the differentiation block of stem cells and, moreover, which liver stem cell lineage is the source cell of hepatocarcinogenesis remain controversial. In this review, we focus on the current status of liver stem cell research and their roles in carcinogenesis of HCC, in order to explore new approaches for stem cell therapy of HCC.

    Treatment of hepatocellular carcinoma (HCC) is guided by the tumour stage. The Barcelona clinical liver cancer (BCLC) score endorsed by the European Society of the Liver EASL divides patients into five prognostic categories, each with a distinct treatment indication. Hepatic resection, orthotopic liver transplantation and percutaneous local ablation are strongly indicated in accurately selected patients with very early (BCLC 0) and early stage (BCLC A) tumours providing a survival rate of between 50 and 75% at year five. In patients with a large tumour burden such as those with intermediate stage BCLC B, repeated treatments with transarterial chemoembolization (TACE) are advocated with clinical benefits (from 16 to 22 months). Survival may also improve in patients who are in poor condition or who do not respond to TACE and those with an advanced HCC (BCLC C), following oral therapy with the multikinase inhibitor, sorafenib. However, most recommendations are based on uncontrolled studies and expert opinions rather than well-designed controlled trials, and up to one-third of patients do not fit recommendations because of advanced age, the presence of significant comorbidities or a strategic location of the nodule. For these patients, treatment of HCC beyond guidelines is often advocated. PMID:26725909

    Full Text Available Malignancy in pregnancy is rare. Carcinomas in pregnancy are mostly kidney cell mass. Renal cell carcinoma (RCC is the commonest malignancy in pregnancy. Because of softness and increased vascularity, rupture of renal cell carcinoma is not uncommon. Here we are presenting a rare case of renal cell carcinoma in pregnancy with spontaneous rupture resulting in massive hemoperitoneum and serious outcome because of late presentation renal cell carcinoma seldom ruptures. A 26 year old woman G2P1L1 with term pregnancy was referred to hospital 80kms away from periphery with non-progression of labour. There was antenatal record suggesting hypertensive disorder of pregnancy in second trimester. On examination, patient was in hypovolemic shock with profuse distension of abdomen. Diagnosis of abruption grade 3 or rupture uterus was made and immediate laparotomy was done. On opening the abdomen, there was hemoperitoneum but uterus was intact. Emergency LSCS done extracted a stillborn baby. There were no retro placental clots also. There was lot of necrotic tissue in the abdomen and there was a tumour arising from lower pole of left kidney which had invaded the renal vessels and had ruptured. Peripartum hysterectomy and left nephrectomy was done. Women did not respond to treatment and died. The objective of presenting this case is the dilemmas faced by the obstetrician in case of shock in 2nd stage of labour. Simple diagnostic tool like renal ultrasound will help to detect at an early stage which could improve the outcome. All cases of hypertensive disorders of pregnancy should be investigated for secondary causes of hypertension. Abdominal USG must be done for all cases of hypertensive disorders of pregnancy in 2nd trimester. Prompt diagnosis and early treatment is the key in management of such condition in pregnancy.

    A randomized controlled trial including 601 patients previously showed that the effectiveness of imiquimod and fluorouracil cream were not inferior to methyl aminolevulinate photodynamic therapy (MAL-PDT) in patients with superficial basal cell carcinoma after 1 year of follow-up. We now present the 3-year follow-up results. The probability of tumor-free survival at 3 years post-treatment was 58.0% for MAL-PDT (95% confidence interval [CI] = 47.8-66.9), 79.7% for imiquimod (95% CI = 71.6-85.7), and 68.2% for fluorouracil (95% CI = 58.1-76.3). The hazard ratio for treatment failure comparing imiquimod with MAL-PDT was 0.50 (95% CI = 0.33-0.76, P = 0.001). Comparison of fluorouracil with MAL-PDT and fluorouracil with imiquimod showed hazard ratios of 0.73 (95% CI = 0.51-1.05, P = 0.092) and 0.68 (95% CI = 0.44-1.06, P = 0.091), respectively. Subgroup analysis showed a higher probability of treatment success for imiquimod versus MAL-PDT in all subgroups with the exception of elderly patients with superficial basal cell carcinoma on the lower extremities. In this subgroup, the risk difference in tumor-free survival was 57.6% in favor of MAL-PDT. In conclusion, according to results at 3 years post-treatment, imiquimod is superior and fluorouracil not inferior to MAL-PDT in treatment of superficial basal cell carcinoma. PMID:27113429

  6. Metastatic renal cell cancer treatments.

    Sternberg, C N

    2003-01-01

    Metastatic renal cell carcinoma has been considered to be resistant to chemotherapy, with responses observed in only limited numbers of patients. For this reason, therapeutic options have ranged from no treatment, to immunotherapy with cytokines such as IL-2 and interferon-alpha, chemotherapy alone or in combination with cytokines, and to a variety of new investigational approaches. Interferon and interleukin-2 (IL-2) have led to long-term survival in selected patients. Immunotherapy with cytokines, monoclonal antibodies, new agents, dendritic cell therapy, and allotransplantation offer promise. Novel therapeutic strategies include combining cytokines, and antiangiogenic approaches such as thalidomide and antivascular endothelial growth factor therapy. Pathologic, cytogenic and molecular studies have proven that renal cell carcinoma is not a single tumor entity. Efforts to improve results also include the identification of prognostic factors, which allow treatment to be better directed towards those patients most likely to benefit. Increasing understanding of cancer biology is beginning to allow for a more targeted approach to the therapy of metastatic renal cell carcinoma. Adequate positioning of known treatments is essential and many trials of new targeted therapies are underway. PMID:14988745

    Full Text Available Francesco Perri1, Francesco Longo2, Franco Ionna2, Francesco Caponigro11Head and Neck Medical Oncology Unit, 2Head and Neck Surgery Unit, National Tumor Institute of Naples, Naples, ItalyAbstract: Cetuximab is a chimeric monoclonal antibody that targets the epidermal growth factor receptor. The role of cetuximab is paramount in several subsets of head and neck cancer. In particular, the EXTREME study has indicated cetuximab as the only drug to improve survival when associated with cisplatin and 5-fluorouracil in patients with recurrent/metastatic disease. Furthermore, cetuximab, both alone and in combination with cisplatin, is active in patients with recurrent/metastatic disease who have failed prior platinum-based chemotherapy. Cetuximab, given in association with radiation therapy, is a treatment of choice in first-line therapy of patients with locally advanced inoperable disease. In the same setting, the role of induction chemotherapy has gained considerable interest over the last few years and a number of efforts are being pursued to optimally integrate induction chemotherapy with radiation therapy plus cetuximab. The combination of cetuximab and other targeted therapies is among the most promising new perspectives for patients with head and neck cancer.Keywords: cetuximab, head and neck cancer, locally advanced, recurrent/metastatic

    To evaluate efficacy and feasibility of chemo-radiotherapy in patients with non-metastatic anal squamous-cell-cancer. TNM staged anal squamous-cell cancer patients were treated with pelvic radiotherapy concomitant to continuous infusion fluorouracil plus cisplatin for at least 2 cycles. In T3-T4 or any T - N+ tumours or in 'slow-responder' cases, 1-2 chemotherapy courses were subsequently administered. Tumour assessment was performed at baseline and 6-8 weeks after radiotherapy to evaluate response. 29 patients were enrolled: 4 males, 25 females; median age 57 years; baseline T1/T2/T3/T4 2/12/7/8; N involvement 17. Median dose pelvic radiotherapy was 59.4 Gy (range: 54-74). In 5 patients 2 chemotherapy courses, in 12 patients three and in 12 patients four courses were performed. At first evaluation, 27 CR (93.1%; 95% CI: 78% - 98%) and 2 SD were observed. Main grade (G) 3 toxic events were neutropenia (8%), diarrhoea (8%) and dermatitis (62%). Most frequent late events G3-G4 occurred in 14 patients: proctitis (5), dermatitis (4), bladder dysfunctions (2), sexual dysfunctions (9), lower extremity venous thromboses (2), dysuria (1), stenosis (1) and tenesmus (1). Five patients reported G1 leucopoenia. The rate of colostomy was 14%. After a median follow up of 42 months (range: 4-81), 20 patients are still alive without relapse and 3 died due to PD. The estimated 7-year DFS was 83.4% (C.I.: 68.3%-98.5%) and the estimated 7-year OS was 85.7% (C.I.: 70% - 100%). The 1-year and the estimated 7-year colostomy-free survivals were 85.9% (C.I.: 73.1% - 98.7%). Concurrent cisplatin plus fluorouracil and radiotherapy is associated with favourable local control rates and acute toxicity. Future investigations will be directed towards research into molecular biomarkers related to disease progression and resistance to chemo-radiotherapy and to the evaluation of new cytotoxic agents or targeted drugs, such as anti-epidermal growth factor receptor, concomitant to RT and to

    Full Text Available : Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by microscopic aggregation of activated macrophages which often develop epithelioid appearance and multinucleate giant cells. Granulomas are encountered in limited number of infectious and some non-infectious conditions. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin’s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC is uncommon, with only few published reports in the literature. We describe a case of conventional (clear cell RCC associated with epithelioid cell granulomas within the tumor parenchyma.

    Full Text Available Abstract Background Renal cell carcinoma can cause various paraneoplastic syndromes including metabolic and hematologic disturbances. Paraneoplastic hypereosinophilia has been reported in a variety of hematologic and solid tumors. We present the first case in the literature of severe paraneoplastic hypereosinophilia in a patient with renal cell carcinoma. Case presentation A 46 year-old patient patient with a history of significant weight loss, reduced general state of health and coughing underwent radical nephrectomy for metastasized renal cell carcinoma. Three weeks after surgery, the patient presented with excessive peripheral hypereosinophilia leading to profound neurological symptoms due to cerebral microinfarction. Systemic treatment with prednisolone, hydroxyurea, vincristine, cytarabine, temsirolimus and sunitinib led to reduction of peripheral eosinophils but could not prevent rapid disease progression of the patient. At time of severe leukocytosis, a considerable increase of cytokines associated with hypereosinophilia was measurable. Conclusions Paraneoplastic hypereosinophilia in patients with renal cell carcinoma might indicate poor prognosis and rapid disease progression. Myelosuppressive therapy is required in symptomatic patients.

    Full Text Available Pelvic squamous cell carcinoma of unknown primary origin has been described in several case reports of female patients. However, there have been no published reports describing male patients with pelvic squamous cell cancer of unknown primary origin. Our case describes a 52-year-old man who presented with right buttock pain, rectal urgency, and constipation. His physical examination demonstrated tenderness to palpation around his gluteal folds. Computed tomography scan of his abdomen and pelvis demonstrated a large mass in his retroperitoneum. The mass was determined to be squamous cell carcinoma of unknown primary origin. Additionally, the patient had small nodules in his right lower lung lobe and right hepatic lobe. The patient was treated with concomitant chemoradiation, including cisplatin and intensity-modulated radiation therapy, followed by carboplatin and paclitaxel. The patient achieved partial remission, in which he remained one year after his presentation. Our case is consistent with the literature which suggests that squamous cell carcinoma of unknown primary origin occurring outside of the head and neck region may have a more favorable prognosis than other carcinomas of unknown primary origin. Further studies are necessary to determine the most appropriate work-up, diagnosis, and optimal treatment strategies.

    Small cell carcinoma (SmCC) is a rare and aggressive neuroendocrine carcinoma of the bladder. Neuroendocrine carcinomas expressing somatostatin receptors (SSTR) in other viscera such as lung, pancreas, and gastrointestinal system respond to therapy with somatostatin analogs. In the present study, expressions of SSTRs 1 to 5 including type 2A are investigated by immunohistochemistry (IHC) and their relationship with clinicopathologic factors was evaluated. Hundred primary bladder SmCC cases were collected from 12 centers in Turkey. Forty-three cases were pure SmCC. Other cases had mostly papillary urothelial carcinoma as a second component. The percentage of the SmCC component ranged from 5% to 100%. SSTR-2A expression was membranous, whereas the other receptors showed cytoplasmic staining. The percentages of positive cases for SSTR-1, SSTR-2A, SSTR-3, SSTR-4, and SSTR-5 were 4% (3/75), 61.4% (54/88), 2.4% (2/84), 24.4% (20/82), and 6.25% (5/80), respectively. The percentage of SmCC component was positively correlated with the percentage of SSTR-2A expression (P=0.003) while negatively correlated with patient age (P=0.032). SSTR-2A expression was correlated with survival as a bad prognostic factor (P=0.018). SSTR-1, SSTR-3, SSTR-4, and SSTR-5 expressions did not show any statistical significance with any parameter. In conclusion, although the limited number of cases with adequate term follow-up, SSTR-2A expression could be a prognostic factor and somatostatin analogs therapeutic candidate for SmCCs of the bladder as these tumors show high percentage of SSTR-2A expression.

The exact incidence of basal cell carcinoma is not known from India but non melanoma skin cancers comprises about 1-2% of cutaneous tumour in India. The most common skin tumour is squamous cell carcinoma in albinism and the incidence of basal cell carcinoma is less. Hereby, we report a peculiar case of basal cell carcinoma in albinism to highlights the importance of early recognition and diagnosis of suspected lesions by performing histopathological examination in unusual circumstances.

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Full Text Available Xp11.2 translocation renal cell carcinomas (TRCCs are a rare family of tumors newly recognized by the World Health Organization (WHO in 2004. These tumors result in the fusion of partner genes to the TFE3 gene located on Xp11.2. They are most common in the pediatric population, but have been recently implicated in adult renal cell carcinoma (RCC presenting at an early age. TFE3-mediated direct transcriptional upregulation of the Met tyrosine kinase receptor triggers dramatic activation of downstream signaling pathways including the protein kinase B (Akt/phosphatidylinositol-3 kinase (PI3K and mammalian target of rapamycin (mTOR pathways. Temsirolimus is an inhibitor of mammalian target of rapamycin (mTOR kinase, a component of intracellular signaling pathways involved in the growth and proliferation of malignant cells. Here we present a case of a 22-year old female who has been treated with temsirolimus for her Xp11.2/TFE3 gene fusion RCC.

  4. Ethacrynic acid: a novel radiation enhancer in human carcinoma cells

    International Nuclear Information System (INIS)

    Purpose: Because agents that interfere with thiol metabolism and glutathione S-transferase (GST) functions have been shown to enhance antitumor effects of alkylating agents in vitro and in vivo, the present study was conceived on the basis that an inhibitor of GST would enhance the radiation response of some selected human carcinoma cells. Ethacrynic acid (EA) was chosen for the study because it is an effective inhibitor of GST and is a well known diuretic in humans. Methods and Materials: Experiments were carried out with well-established human tumor cells in culture growing in Eagle's minimum essential medium (MEM) supplemented with 10% fetal calf serum (FCS). Cell lines used were MCF-7, MCF-7 adriamycin resistant (AR) cells (breast carcinoma), HT-29 cells (colon carcinoma), DU-145 cells (prostate carcinoma), and U-373 cells (malignant glioma). Cell survival following the exposure of cells to drug alone, radiation alone, and a combined treatment was assayed by determining the colony-forming ability of single plated cells in culture to obtain dose-survival curves. The drug enhancement ratio was correlated with levels of GST. Results: The cytotoxicity of EA was most pronounced in MCF-7, U-373, and DU-145 cells compared to MCF-7 AR and HT-29 cells. The levels of GST activity were found to be lower in those EA-sensitive cells. A significant radiation enhancement was obtained with EA-sensitive cells exposed to nontoxic concentrations of the drug immediately before or after irradiation. The sensitizer enhancement ratio (SER) of MCF-7 cells was 1.55 with EA (20 μg/ml), while the SER of MCF-7 AR was less than 1.1. Based on five different human tumor cells, a clear inverse relationship was demonstrated between the magnitude of SER and GST levels of tumor cells prior to the combined treatment. Conclusion: The present results suggest that EA, which acts as both a reversible and irreversible inhibitor of GST activity, could significantly enhance the radiation response of

  5. Study of a new tumor marker, CYFRA 21-1, in squamous cell carcinoma of the cervix, and comparison with squamous cell carcinoma antigen

    International Nuclear Information System (INIS)

    The diagnosis value of a new tumor marker, CYFRA 21-1, was studied in the blood samples collected from 22 controls, and 87 pre-treatment patients with squamous cell carcinoma of the cervix. Sensitivity and specificity of CYFRA 21-1 was was compared with those of squamous cell carcinoma antigen (SCC) measured in the sera of the same patients. Serum CYFRA 21-1 levels were higher in patients with squamous cell carcinoma than in controls (p < 0.05), and correlated with FIGO stage (Stage IIb-IV vs. Stage Ib-IIa, p = 0.0477). Using 2.5 ng/ml as cut-off value, elevated CYFRA 21-1 levels were found in 13.6% of controls, 34.8% of patients with Stage Ib-IIa squamous cell carcinoma of the cervix, and 63.5% of patients with Stage IIb-IV squamous cell carcinoma of the cervix. However, there was less sensitivity and specificity of CYFRA 21-1 than those of SCC in detecting squamous cell carcinoma of the cervix. CYFRA 21-1 may not be a better tumor marker than SCC for squamous cell carcinoma of the cervix. (author)

    Metastasis is the major cause of death among cancer patients, yet early detection and intervention of metastasis could significantly improve their clinical outcomes. We have sequenced and analyzed RNA (Expression) and DNA (Mutations) from the primary tumor (PT), tumor extension (TE) and lymphatic metastatic (LM) sites of patients with clear cell renal cell carcinoma (CCRCC) before treatment. Here, we report a three-nucleotide deletion near the C-region of Plk5 that is specifically associated with the lymphatic metastasis. This mutation is un-detectable in the PT, becomes detectable in the TE and dominates the LM tissue. So while only a few primary cancer cells carry this mutation, the majority of metastatic cells have this mutation. The increasing frequency of this mutation in metastatic tissue suggests that this Plk5 deletion could be used as an early indicator of CCRCC metastasis, and be identified by low cost PCR assay. A large scale clinical trial could reveal whether a simple PCR assay for this mutation at the time of nephrectomy could identify and stratify high-risk CCRCC patients for treatments. PMID:26908440

    Laryngeal spindle cell carcinoma (SpCC) is an uncommon subtype of squamous cell carcinoma which represents 0.5% of all laryngeal squamous cell carcinomas. It is a biphasic tumor consisting of the combination of a malignant mesenchymal spindle cell component and a squamous cell component that includes dysplasia, carcinoma in situ, or invasive carcinoma. Although it has aggressive biological features, the probability of making a diagnosis in the early stages is high as it often leads to obstructive symptoms in the early period. Due to its low incidence, there is no clear consensus on prognostic factors and optimal treatment strategies yet. In this paper, a 60-year-old laryngeal SpCC case that was effectively treated with wide local excision followed by adjuvant radiotherapy was presented with the literature. PMID:26788392

    Basal cell carcinomas of the skin and subcutaneous tissue of the face can spread into to orbit directly through the anterior orbit. Nine patients with radiological evidence of orbital involvement by basal cell carcinoma were studied with computed tomography. None of the patients had any previous treatment of the tumor. Ulcerated lesion of the eyelid was the most common sign of the disease (67%) whereas the inferior eyelid was the most frequent site of origin of the neoplasm (44%). All carcinomas extended into the orbit through the anterior orbit, involving mainly the extraconal space (89%). The orbital regions most frequently involved were the anterior, medial and superior compartments. Orbital extension of these carcinomas can result in orbital exenteration. Computed tomography is a valuable method for evaluating tumoral extension into the orbit and should be done when there is clinical suspicion of orbital involvement. (author)

    Full Text Available Context Squamous carcinoma of the ampulla of Vater is a very rare tumor with only three cases been reported so far. Case report Here, we report the case of a 68-year-old man who presented with painless obstructive jaundice, general fatigue, loss of appetite and weight loss. Laboratory tests revealed hypochromic anemia. Total and direct bilirubin, alkaline phosphatase, liver enzymes, carbohydrate antigen 19-9 (CA 19-9 and carcinoembryonic antigen (CEA were all elevated. Abdominal ultrasonography and computed tomography showed a distended gallbladder, dilatation of the intra- and extra-hepatic bile ducts and enlargement of the pancreatic head. Endoscopic retrograde cholangiopancreatography revealed a bulging papilla with infiltrative growth at the ampulla of Vater but endoscopic biopsies were inconclusive. The patient was treated with classical Whipple’s pancreaticoduodenectomy. Histopathological examination showed a moderately differentiated squamous cell carcinoma. Multiple serial sectioning of the tumor specimen failed to detect an adenomatous component. Regional lymph nodes and resection margins were free of tumor and the disease was classified as stage IIA (T3N0M0 according to the TNM system. Adjuvant treatment was not given. Despite curative resection, multiple liver metastases developed after four months and the patient succumbed to progressive hepatic failure 5 months after the operation. Conclusion Primary pure squamous cell carcinoma of the ampulla of Vater is a very rare histological type of carcinoma. Clinical characteristics and optimal treatment are obscure. Primary surgical treatment with curative intent should be performed although this type of carcinoma associates with dismal prognosis.

  18. Review of photodynamic therapy with 5-methyl aminolevulinate in actinic keratosis, epidermoid carcinoma and basal cell carcinoma

    International Nuclear Information System (INIS)

    A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities

    This retrospective study was undertaken to analyze data from patients receiving iodine-125 ([{sup 125}I]) seed brachytherapy postoperatively for the treatment of acinic cell carcinoma (ACC) of the parotid gland along with the following risk factors: residual tumor, recurrent tumor, facial nerve invasion, positive resection margins, advanced tumor stage, or tumor spillage. Twenty-nine patients with ACC (17 females, 12 males; age range, 13-73 years; median age, 37.3 years) were included. Median follow-up was 58.2 months (range, 14-122 months). Patients received [{sup 125}I] seed brachytherapy (median actuarial D90, 177 Gy) 3-41 days (median, 14 days) following surgery. Radioactivity was 18.5-33.3 MBq per seed, and the prescription dose was 80-120 Gy. The 3-, 5-, and 10-year rates of local control were 93.1, 88.7, and 88.7 %, respectively; overall survival was 96.6, 92, and 92 %; disease-free survival was 93.1, 88.4, and 88.4 %; and freedom from distant metastasis was 96.6, 91.2, and 91.2 %. Lymph node metastases were absent in all patients, although two patients died with distant metastases. Facial nerve recovery was quick, and no severe radiotherapy-related complications were noted. Recurrence history, local recurrence, and distant metastasis significantly affected overall survival. Postoperative [{sup 125}I] seed brachytherapy is effective in treating ACC and has minor complications. Patients with a history of recurrence showed poor prognosis and were more likely to experience disease recurrence and develop metastases. (orig.)

    International Nuclear Information System (INIS)

    To report our long-term results with postoperative intensity-modulated radiation therapy (IMRT) in patients suffering from squamous-cell carcinoma (SCC) of the oral cavity or oropharynx. Seventy five patients were retrospectively analyzed. Median age was 58 years and 84 % were male. 76 % of the primaries were located in the oropharynx. Surgery resulted in negative margins (R0) in 64 % of the patients while 36 % suffered from positive margins (R1). Postoperative stages were as follows: stage1:4 %, stage2:9 %, stage3:17 %, stage4a:69 % with positive nodes in 84 %. Perineural invasion (Pn+) and extracapsular extension (ECE) were present in 7 % and 29 %, respectively. All patients received IMRT using the step-and-shoot approach with a simultaneously integrated boost (SIB) in 84 %. Concurrent systemic therapy was applied to 53 patients, mainly cisplatin weekly. Median follow-up was 55 months (5–150). 13 patients showed locoregional failures (4 isolated local, 4 isolated neck, 5 combined) transferring into 5-year-LRC rates of 85 %. Number of positive lymph nodes (n > 2) and presence of ECE were significantly associated with decreased LRC in univariate analysis, but only the number of nodes remained significant in multivariate analysis. Overall treatment failures occurred in 20 patients (9 locoregional only, 7 distant only, 4 combined), transferring into 3-and 5-year-FFTF rates of 77 % and 75 %, respectively. The 3-and 5-year-OS rates were 80 % and 72 %, respectively. High clinical stage, high N stage, number of positive nodes (n > 2), ECE and Pn1 were significantly associated with worse FFTF and OS in univariate analysis, but only number of nodes remained significant for FFTF in multivariate analysis. Maximum acute toxicity was grade 3 in 64 % and grade 4 in 1 %, mainly hematological or mucositis/dysphagia. Maximum late toxicity was grade 3 in 23 % of the patients, mainly long-term tube feeding dependency. Postoperative IMRT achieved excellent LRC and good OS with

    Full Text Available Objective: The aim of this study was to investigate p53 and COX-2 expressions in basal cell carcinoma, squamous cell carcinoma and actinic keratoses, and to determine a possible relationship.Material and Method: 50 basal cell carcinoma, 45 squamous cell carcinoma and 45 actinic keratosis cases were evaluated. The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

  5. Metastatic Renal Cell Carcinoma Initially Presented as a Tongue Mass

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Renal cell carcinoma is one of the most common tumours after lung and breast cancer to metastasize to the head and neck. Initial presentation by tongue metastasis is extremely rare. A 67-year-oldmale presented with a 4.8 cm mass on his tongue. The result of the punch biopsy from the tongue was diagnosed as a clear cell variant of squamous cell carcinoma. The biopsy was reevaluated due to the renal mass found during the check-up and the rapid enlargement of the mass. The excision of the tongue mass and the radical nephrectomy material confirmed the diagnosis of a metastatic renal cell carcinoma in the tongue and renal cell carcinoma in the kidney. Since metastasis of renal cell carcinoma to the tongue is uncommon it may cause difficulties in diagnosis and proper management. The metastasis of renal cell carcinoma should always be considered in the differential diagnosis among the clear cell neoplasms.

    Full Text Available Large cell neuroendocrine tumor of the urinary bladder is very rare. It is a type of neuroendocrine carcinoma that is morphologically different from small cell carcinoma.This manuscript describes a 67-year-old man who presented with hematuria. Ultrasonogrophic and computer tomography revealed a 5 cm mass in right posterolateral wall of the bladder that invaded perivesical tissue and he subsequently underwent transurethral resection. Microscopic examination showed a tumor with a sheet-like and trabecular growth pattern comprising necrotic areas which infiltrated the muscularis propria. Tumoral cells had coarse chromatin, prominent nucleoli, moderate amount of cytoplasm and immunohistochemically stained strongly positive with synaptophysin, chromogranin and CD56.There are only few case reports of large cell neuroendocrine tumor of the urinary bladder so the biological behavior and the treatment protocol of these tumors are still obscure. Appropriate management protocols and prognostic estimation could be achived by the increased number of cases being reported. Therefore in a case of a poorly differentiated tumor in bladder, although rare, it is important to consider large cell neuroendocrine carcinoma in differential diagnosis.

    Full Text Available Squamous cell carcinomas are the most commonly diagnosed oral malignancy, accounting for about 90% of all malignant oral lesions. Detection of the condition at early stages is rare; as a result, the clinical and histological characteristics and prognosis of this tumor have not been extensively investigated. The objective of this study was to evaluate clinical and microscopic features of squamous cell carcinomas using immunohistochemical analysis and assessing biological markers of angiogenesis and tumor vascular activity (anti-CD31, anti-CD34, Factor VIII, cell proliferation (Ki-67, and loss of cell suppression (p53. Tolonium chloride 1% was used to determine the optimal biopsy site. Six patients seen at the Stomatology Service of a university hospital in Canoas, southern Brazil, with a suspected diagnosis of squamous cell carcinoma were analyzed. All patients were male, with a mean age of 56.6 years, and four had a white skin color. Lesions were detected in the tongue (4 and tonsillar pillar (2. All diagnoses were confi rmed by microscopy (hematoxylin-eosin staining. Immunohistochemical analysis revealed p53 expression in 5 of the cases, Ki-67 in 6, and anti-CD34 in 1; anti-CD31 and Factor VIII were not detected in any patient. Our fi ndings suggest an important contribution of tumor markers in the diagnosis and prognosis of these malignancies, as well as in treatment planning.

    Full Text Available Relata-se caso incomum de carcinoma basocelular que simulava tumor intranasal de crescimento expansivo, na cavidade da narina esquerda. Operado com cirurgia micrográfica pelo método de Munique, foi possível demonstrar que o tumor se originava da pele aparentemente normal e suprajacente do nariz. Por ser tridimensional, esse método de cirurgia micrográfica permite estudo mais preciso da peça cirúrgica. Discutem-se também aspectos peculiares da cirurgia micrográfica pelo método de Munique, o que contribui para a ampliação do conceito das cirurgias microscopicamente controladas.A rare case of basal cell carcinoma mimicking an expansive intranasal tumor in the left nostril is reported. Through the Munich micrographic surgery method, it was possible to demonstrate that the tumor originated from the apparently normal nose skin. Since this micrographic surgery is a tri-dimensional method, it enables a more accurate study of the specimen. Some peculiar aspects of the micrographic surgery using the Munich method are discussed, thus contributing to further understanding about the concept of microscopically controlled surgeries.

    A case of clear cell odontogenic carcinoma of the oral cavity is described in this sine qua non radiology-pathology correlation article. CT demonstrated a solid and cystic mass arising from the mandible. Histology demonstrated variably-sized nests of clear to pale eosinophilic cells with occasional central necrosis embedded in a hyalinized to fibrocellular stroma. The specimen was also positive for the characteristic rearrangement of the EWSR1 (22q12) locus in 93.5 % of interphase cells. PMID:25994920

    Multilocular Cystic Renal Cell Carcinoma (MCRCC) represents a rare variant of clear cell (conventional) renal cell carcinomas. Attributable to its distinct characteristics in prognosis and its natural history, MCRCC was recognised as a separate subtype of renal cell carcinoma in the 2004 WHO classification of adult renal tumors. We report this case of MCRCC from antemortem surgical specimen, due to its unusual gross appearance and a rare clinical entity.

    Sarcomatoid renal cell carcinomas of the kidney are rare neoplasms constituting about 1-5% of all renal malignant neoplasms. These are aggressive tumors and are commonly associated with conventional (clear cell) renal cell carcinomas, but cases associated with chromophobe renal cell carcinomas are sparse. Cytological features of such lesions have rarely been reported. Here, we report a unique case of a 48-year-old male patient who presented with right flank lump and pain. A fine needle...

    Immunohistochemical analysis of the protein expression c-myc, ets 1, ets 2, TPR-met, c-fos, c-jun, c-ras-pan, p53, yes, src in 79 samples of normal, metaplastic squamous epithelium, intraepithelial and invasive squamous cell carcinoma of uterine cervix was performed using polyclonal rabbit antibodies to the synthetic peptides homologous active areas of corresponding oncoproteins. Higher content of myc, fos, ets2, p53, ras is noted in metaplasia, dysplasia and in tumours as compared to the normal tissues. Protein myc is revealed in the cytoplasm at a grave dysplasia and in the nucleus in the intraepithelial carcinoma: this may serve as a criterion at a differential diagnosis of these conditions. Expression of the oncoproteins fos, ets2, p53, src in the metaplastic squamous cell carcinoma was higher than in the true squamous cell (ectocervical) carcinoma. When compared to the advanced carcinomas, increase of ets2, p53, and at some degree that of myc, the increase is noted in the latter. Invasive carcinoma with a high level of oncoproteins showed a tendency to the synchronization of myc and ras expression. Poor prognosis was associated with a low level (before treatment) of the expression of the majority of the oncoproteins studied. PMID:7848100

    Metastatic renal cell carcinoma (RCC) has historically been refractory to cytotoxic and hormonal agents; only interleukin 2 and interferon alpha provide response in a minority of patients. We reviewed RCC biology and explored the ways in which this understanding led to development of novel, effective targeted therapies. Small molecule tyrosine kinase inhibitors, monoclonal antibodies and novel agents are all being studied, and phase II studies show promising activity of sunitinib, sorafenib a...

    Basal cell carcinoma (BCC) presents with diverse clinical features, and several morphologic and histologic variants of BCC have been reported [Sexton et al.: J Am Acad Dermatol 1990;23:1118-1126]. Linear BCC was first described as a new clinical subtype in 1985 by Lewis [Int J Dematol 1985;24:124-125]. Here, we present a case of linear BCC that we recently encountered in an elderly Japanese patient, and review other cases reported in Japan.

    Full Text Available Clear cell odontogenic carcinoma is a rare neoplasm with very few cases reported in the literature. We report a case of a 50-year-old female patient with the malignancy at a less common location. Diagnosis was given based on the histopathologic findings. The demographic data and understanding for this tumor needs to be strengthened by reporting all new cases, which are diagnosed, in literature.

    Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. Most BCCs are found on areas of UV-damaged skin, The study of BCCs of sun-protected regions, however, suggests a more complex pathogenesis. We present a case of BCC of the perineum in a man with no previous history of skin cancer. This is the first report of BCC in this region and one of a small body of cases arising on or near the genital and perianal regions.

    Full Text Available Acinar cell pancreatic carcinoma is a rare solid malignant neoplasm. Recent review of the literature showed occasional cases with papillary or papillocystic growth patterns, ranging from 2 to 5 cm in diameter. We report a large 10 cm pancreatic tumor with papillocystic pathology features involving the pancreatic head. The growth pattern of these tumors could be mistaken for intraductal papillary mucinous tumors or other pancreatic cystic neoplasms.
