Expression of Tumor Markers in Circulating Tumor Cells of Metastatic Hormone-sensitive Prostate...

Prostate Cancer

As prostate cancer progresses, tumor cells dissociate and enter the bloodstream. Considered a "liquid biopsy," these circulating tumor cells (CTC) can show how a patient's cancer evolves and responds to treatments. The purpose of this study is to determine whether sequentially analyzing the expression of tumor markers in circulating tumor cells in newly diagnosed metastatic hormone-sensitive prostate cancer patients can predict the outcome of these patients.

The Value Of Circulating Tumor Cells In Patient With NSCLC In Postoperative Recurrence Monitoring...

Non-small-cell Lung Carcinoma

The purpose of this study is to assess the value of circulating tumor cells (CTC)for non-small cell lung cancer in the postoperative recurrence monitoring by comparing the CTCs, CT and tumor markers at different time points.The time of CTC and carcinoembryonic antigen(CEA) detection is baseline, 2~7 days, 3 months, 6 months, 12 months, 24 months, 36 months after the surgery. And the time of CT detection is 6 months, 12 months, 24 months, 36 months after the surgery.

Circulating Tumor Cells in mCRC for Liver Resection

Metastatic Colorectal CancerCirculating Tumor Cell

Resection of liver metastasis is potentially curative in patients with colorectal cancer bearing liver metastasis. However, early recurrence occurs in up to 30% in 3 months after liver resection. To optimize patient selection, the investigators propose to evaluate the the value of incorporating circulating tumor cells enumeration to clinical factors in a prospective study

Effects of Chemotherapy on Circulating Tumor Cells and Recurrences in Cervical Cancer Patients

Cervical Cancer

Cervical cancer is a major health problem for Chinese women. It is estimated that nearly 100,000 new cervical cancer cases occur in China every year, which accounts for about 20 percent of global new cases. Surgery and radiotherapy are two major radical treatment methods for IB-IIB cervical cancer. Unlike the United States and some other countries, most of operable women with IB-IIB cervical cancer received radical surgery other than radiotherapy in China. Patients with recurrence risk factors (lymph node metastasis, deep stromal invasion, positive lymphatic vascular space, et al. ) also received adjuvant therapy after surgery, such as radiotherapy or chemoradiotherapy that are recommended in the NCCN guidelines. However, in China a substantial part of patients especially those admitted to tertiary hospitals received several courses of chemotherapy instead of radiotherapy if they had recurrence risk factors . In our previous study, we found that patients with intermediate risk factors (deep stromal invasion, positive lymphatic vascular space, bulky tumor>4cm) had better disease-free survival and recurrence-free survival when they received chemotherapy compared with radiotherapy. The objective in this study is to investigate whether the advantage of postoperative chemotherapy is a result of circulating tumor cells (CTC) in some of the patients with intermediate risk factors.
