This non-interventional, multicenter, prospective study aimed to evaluate the real-world activity of trabectedin, and its impact on symptom burden and quality of life in patients with advanced soft tissue sarcoma (aSTS) treated in routine clinical settings in Greece. Patients with histologically confirmed aSTS newly initiated on trabectedin were enrolled. The primary endpoint was progression-free survival (PFS) rate at 6 months.

Thromboprophylaxis, as a preventive measure for cancer-associated thrombosis (CAT), may be beneficial for patients with active cancer and high-risk for thrombosis. The present post hoc analysis include a total of 407 patients enrolled in the Greek Management of Thrombosis study, who received thromboprophylaxis with tinzaparin. The objectives of the present analysis were: i) To obtain sufficient evidence for the administration of prophylaxis in patients with active cancer, irrespective of Khorana risk assessment model score; ii) to identify the selection criteria for both dose and duration of tinzaparin; and iii) to evaluate the efficacy and safety of tinzaparin administered for CAT prophylaxis.

Pancreatic cancer (PaC) induces a prothrombotic and hypercoagulable state. The aim of this study was to investigate the effect of tinzaparin in combination with chemotherapy. The PaCT (pancreatic cancer and tinzaparin) study was a retrospective observational study that collected data regarding progression free survival (PFS) in advanced or metastatic PaC patients who received thromboprophylaxis with tinzaparin during chemotherapy with nab-paclitaxel (N) and gemcitabine (G).

Cancer patients are at high risk for cancer-associated thrombosis (CAT). CAT is the second leading cause of death in these patients but it can be preventable with thromboprophylaxis. An observational, prospective, multicenter study aiming to record CAT management in clinical practice was conducted by the Hellenic Society of Medical Oncology (HeSMO).

Background: Cancer-associated thrombosis (CAT), the second leading cause of death in patients with cancer can be treated with low molecular weight heparin (LMWH) according to guidelines.

Patients And Methods: A multicenter prospective observational study was carried out to record anti-thrombotic treatment practice, assess thrombosis recurrence and bleeding, and identify potential risk factors. Adult patients from 18 Oncology Departments throughout Greece were followed-up for 12 months.

Background/aims: There is little information in the literature on the use of bevacizumab (BV) combination chemotherapy in multiple lines with regimens including irinotecan and oxaliplatin, in metastatic colorectal cancer (mCRC) patients with disease progression. The aim of this small retrospective institutional study is to compare the efficacy and safety of the continuation of BV in combination with various chemotherapeutic agents, within the framework of multiple line therapy in progressed mCRC patients.

Methodology: Our retrospective study included 21 patients with mCRC that had received at least one course of irinotecan-based or oxaliplatin-based chemotherapy with BV before disease progression.

Background/aims: Although research on new effective treatments against pancreatic cancer is intense, limited therapeutic schemes are currently approved. The aim of the present study was to record the efficacy and safety of gemcitabine-erlotinib plus docetaxel combination therapy in patients with advanced and/or metastatic pancreatic cancer.

Methodology: Twenty-five chemotherapy naive patients with histologically confirmed unresectable pancreatic cancer and documented extrapancreatic metastases, received biweekly gemcitabine 1,500mg/m2 during a 28-day long cycle; daily erlotinib 100mg per os; and docetaxel 80mg/m2 as intravenous infusion administered every 15 days.

Small-cell lung cancer is the most aggressive lung cancer, with a dismal prognosis. The authors present a case report of a patient with limited-stage small-cell lung cancer who underwent a thoracotomy for diagnostic purposes, with the diagnosis being made after surgical excision. Combination chemotherapy remains the cornerstone of treatment for both limited and extensive disease.
