Squamous cell carcinoma of the penis is a rare tumor in Europe, whose prognosis and survival are influenced by metastatic lymph node involvement. Its frequency in France is estimated at less than 1% of human cancers. This spread follows a sequential process via the superficial and deep inguinal lymph nodes and then to the pelvic lymph nodes before metastatic dissemination. The management of inguinal areas is the cornerstone of penile cancer. It is curative in about 80% of patients with 1 or 2 inguinal metastases. 5-years overall survival was on average 85% for pN0 patients and 40% for pN+ patients. For pN+ patients, 5-year overall survival was 70 to 80% for pN1 (only 1 lymph node invasion), 30 to 40% for pN2, and 0 to 10% for pN3. The risk of local recurrence is 5-10% for pN0 and 20-30% for pN+ after local treatment by lymphadenectomy alone without chemotherapy. The average time to recurrence was 10 months. Disease-free survival at 5 years is 75-85% for pN0 and 30-45% for pN+. Its indication depends on clinical examination (presence or absence of lymph nodes palpated) and the risk of nodal disease (≥pT1bG2). Currently, a fine needle biopsy is the best clinical diagnosis method because it is a simple, low risk, and possible in consultation. When the result is positive, it allows an early dissection. Single or double fine needle biopsy will be used in cN+ patients. For patients at risk of lymp nodes involvement (cN0 and ≥pT1B or G2), the sentinel node diagnosis may be followed by modified or bilateral lymphadenectomy. Although lymphadenectomy alone has a curator action, it sometimes remains insufficient in patients with metastatic lymph node involvement. Therefore it seems important to develop a multimodal approach in the management of these patients in order to increase the response rate to treatment and survival. From a Phase II trial conducted on 30 patients, the combination TIP (paclitaxel, ifosfamide, and cisplatin) appears to have an efficacy / toxicity acceptable. The TIP protocol has therefore been chosen for this trial as adjuvant or neo-adjuvant treatment in patients with high risk of lymph nodes involvement (cN0 and ≥pT1B or G2), and with inguinal mobile palpated lymph nodes (cN+) respectively, after lymph nodes involvement proven (pN+).
Esophageal squamous cell carcinoma (ESCC) is one of the ten leading cancers in Taiwanese male. The prognosis is poor with a five-year overall survival rate of 10 to 30 %. Randomized clinical trials have demonstrated that trimodality therapy (TMT), consisted of neoadjuvant concurrent chemoradiation (CCRT) and radical esophagectomy, improves the overall survival for patients with locally advanced disease. Despite of the advancement, the outcome remained unsatisfactory with the median progression-free survival around 20 to 25 months and median overall survival around 30 months. It is know that the most important prognostic factor is whether a pathological complete response can be achieved after neoadjuvant CCRT. However, the use of new generation chemotherapeutic agent taxanes and epidermal growth factor inhibitors (such as Cetuximab) failed to significantly improve prognosis comparing to the standard platinum-fluorouracil (PF) regimen. As a consequence, it is mandatory to develop new chemotherapeutic regimen for CCRT. In previous prospective studies, investigators used proximal ligation assay technology to identify serum VEGF-A in correlation with the pathological response and prognosis for patients receiving neoadjuvant CCRT plus radical esophagectomy for locally advanced ESCC. Other investigators also showed high VEGF expression correlating to poor outcome. Therefore, investigators generate the hypothesis that adding vascular endothelial growth factor (VEGF) monoclonal antibody, Bevacizumab, to standard neoadjuvant CCRT may improve outcome for patients with ESCC. Meanwhile, several prospective clinical studies have shown the feasibility, safety, and activity of adding Bevacizumab to chemotherapy, CCRT, or combined modality therapy including surgery, either in head and neck cancer, esophageal cancer, or esophagogastric junction adenocarcinoma. However, its efficacy should be further investigated in larger prospective trials and little is known about the activity and toxicity of Bevacizumab in ESCC due to small number of reported cases. In the present clinical trial, investigators plan to investigate whether incorporation of Bevacizumab into standard neoadjuvant PF-CCRT will improve treatment response and increase pathological complete response rate. Investigators will also evaluate associated biomarkers in relation to prognosis. By the present research, investigators expect to develop a new TMT regimen for this poor prognostic disease.
The aim of the study is to test whether a resource-sparing 4-week, 20-fraction course of accelerated hypofractionated radiotherapy is non-inferior to accelerated radiotherapy delivering 33 fractions over 5.5 weeks in the treatment of patients with Stage I-IV squamous cell carcinoma of the pharynx, larynx and oral cavity with the exception of paranasal sinus, nasopharyngeal and stage I-II glottic carcinomas.
The purpose of this study is to determine whether cervical lymph node dissection is necessarily performed in the presence of early-stage oral squamous cell carcinoma.
The research and development of novel anti-tumor agents in oral cancer is slow, the investigation of repositioning use of currently available drugs in clinical, such as a selective cyclooxygenase-2 (COX-2) inhibitor (Celebrex/Celecoxib) maybe a potential alternative strategy.
This phase II trial studies how well radiation therapy with or without cisplatin works in treating patients with stage III-IVA squamous cell carcinoma of the head and neck who have undergone surgery. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known if radiation therapy is more effective with or without cisplatin in treating patients with squamous cell carcinoma of the head and neck.
Aim of the study is to verify wether it is possible to have a more sensitive diagnostic tool using pancytokeratin immunohistochemistry for desmoplastic squamous cell carcinoma compared to regular H&E staining. The investigators therefore plan to include 73 participants with a confirmed diagnosis of desmoplastic squamous cell carcinoma and do regular follow up.
The purpose of this study is to see how useful the information provided from Positron Emission Tomography (PET) scans can be in the actual planning and delivery of radiation treatment to patients who have head and neck cancers. Patients participating in this study, will have (in addition to their routine tests) a PET scan before and during their radiation treatment. Following the intervention, patients will be followed as per standard practice.
