Active clinical trials for "Carcinoma"

Occult lymph node metastasis is common in micro papillary thyroid cancer. However, the role of lymph node dissection in the treatment of microPTC remains controversial. The investigators want to investigate the usefulness routine central dissection and sentinel lymph node biopsy in prognosis of micro PTC. This is a prospective randomized control study. The investigators started this study from May of 2009 and this study will be continued until Dec. 2011.

The purpose of this study is to elucidate the influence of anti-hepatitis B virus therapy on safety and survival of HCC patient after transcatheter arterial chemoembolization.

The primary objective of this study is to assess the efficacy of SIRT as compared with Sorafenib in patients with locally advanced liver cancer in terms of overall survival (OS). The Study null hypothesis is, there is no difference in overall survival between patients receiving SIRT and those receiving Sorafenib therapy.

Evaluation of the effectiveness of escitalopram on depressive symptoms after 3 months in patients with head and neck squamous cell carcinomas (oral cavity, larynx, oropharynx and hypopharynx) and with an HADS total score > 11

This research trial studies chitinase 3-like 1 (cartilage glycoprotein-39) (YKL-40) in serum samples from patients with newly diagnosed stage III-IV ovarian epithelial, primary peritoneal cavity, or fallopian tube cancer receiving chemotherapy. Studying samples of serum in the laboratory from patients receiving chemotherapy may help doctors learn more about the effects of chemotherapy on cells. It may also help doctors understand how well patients respond to treatment.

Most hepatocellular carcinomas are associated with hepatitis B virus, it is hypothesized that anti-viral treatment may be helpful in treating HBV-related hepatocellular carcinoma.

The purpose of this study is to investigate safety and potential therapeutic benefits for patients with hepatocellular carcinoma by transcatheter chemoembolization with the recombinant endostatin (commercially available in China)which is also administrated via the hepatic artery. The hypothesis of this protocol is that TACE with antiangiogenic treatment may inhibit the proangiogenic effects induced by the hypoxia of TACE.

Hepatoma ranks the first on the cancer mortality list in Taiwan, and there are currently no other effective treatment options for advanced HCC. Therefore, alternative medical intervention is needed to improve the survival and quality of life of these patients. Dendritic cells are the most potent type of antigen presenting cells in the human body, and are involved in the regulation of both innate and adoptive immune responses. If we use matured antigen presenting cells pulsed in vitro with appropriate tumor associated antigens under optimal activation conditions. It is anticipated that such treatment might generate or reactivate a cytotoxic T lymphocyte response against tumor cells and thereby inhibit tumor growth. Although there are excited results of tumor vaccine in animal models but successful clinical tries are rare. There are still some problems needed to be resolved such as immune deficiency of the cancer patients or the defect of T cell receptors or the problems of tumor escape. There are complex compositions in tumor cells to be a tumor antigen that will influence the efficacy of tumor vaccine, so we are going to use tumor lysate to be a tumor antigen. In this study, the generation of dendritic cells from the patient's peripheral blood will use rhGM-CSF and rhIL-4 as stimulating factors, and matured dendritic cells will pulse with tumor lysate, the ex vivo T cell cytotoxicity for the primary tumor cell will be test. We hope to cooperate with basic study group in our hospital to do more ex vivo tests and clinical trials in the future.

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant or tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving fulvestrant or tamoxifen before surgery may be an effective treatment for breast cancer. PURPOSE: This randomized clinical trial is studying how well giving fulvestrant or tamoxifen works in treating postmenopausal women who are undergoing surgery for ductal carcinoma in situ of the breast.

Primary Objective: To analyse time to tumor progression in patients cystectomized for locally advanced transitional cell carcinoma (TCC) of the bladder, who are not suitable for cisplatin-based chemotherapy (i.e. postoperative reduced renal function, advanced age). Patients are randomized to receive either adjuvant gemcitabine immediately after radical operation (treatment arm A) or no treatment (control arm B). Patients in the control arm are to be treated with gemcitabine as soon as tumor progression becomes evident clinically and/or radiologically. Secondary Objectives: The secondary objectives of this study are: Estimation of time-specific survival probabilities irrespective of causes of death. Assessment of toxicity and tolerability of gemcitabine Description of survival experience of patients in the control arm beyond the time of initiating chemotherapy. Assessment of quality of life (European Organization for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire [QLQ]-C30). Study Design: This is an open-label, prospective, multicenter, randomized, controlled phase 3 two-arm study using gemcitabine as a single agent in chemonaive cystectomy patients with locally advanced TCC of the bladder in an adjuvant setting. The patients will receive the following treatment: Arm A (treatment): gemcitabine 1250 mg/m2 intravenously once a week for 2 weeks (days 1 and 8) followed by 1-week rest period. Repeat cycle on day 22. Maximum of 6 cycles. Begin treatment until 3 months after radical operation (within first 6 weeks is recommended). Arm B (control): No immediate post-surgery treatment. Watchful waiting; treatment only conditionally in case of progression with gemcitabine (dose and schedule as in arm A).
