BACKGROUND: After experiencing a distant recurrence, breast cancer patients have a poor prognosis; fewer than 5% survive for ten or more years. However, the time to death is highly variable, ranging from a few months to many years. The purpose of this study is to identify, in a large hospital-based series of patients with early-stage breast cancer, factors which predict survival after distant recurrence. METHODS: We studied a cohort of 2312 women diagnosed with invasive breast cancer at Women's College Hospital between 1987 and 2000 (stages I-III)...

The main clinical goal for patients with advanced or metastatic thoracic cancer is palliation of tumor-related symptoms and improvement of quality of life. The aim of this phase I-II trial was to define the maximum tolerated dose (MTD) of a short-course of palliative radiotherapy (RT) and to evaluate its efficacy in terms of palliative response. A phase I trial was planned with escalating dose increments. Total doses ranged from 16 to 20 Gy delivered (BID) in two consecutive days. Dose limiting toxicity was defined as any acute grade ≥ 3 toxicity based on the RTOG scale...

Background: Chemoradiation (CRT) or short-course radiotherapy (SCRT) are standard treatments for locally advanced rectal cancer (LARC). We evaluated the efficacy/safety of two neoadjuvant chemotherapy (NACT) regimens as an alternative prior to total mesorectal excision (TME). Methods/design: This multi-centre, phase II trial in patients with magnetic resonance imaging (MRI) defined high-risk LARC (>cT3b, cN2+ or extramural venous invasion) randomised patients (1:1) to FOLFOX + Bevacizumab (Arm 1) or FOLFOXIRI + bevacizumab (Arm 2) every 14 days for 6 cycles prior to surgery...

PURPOSE: This study aimed to assess the feasibility to plan and deliver highly heterogeneous doses to symptomatic large tumors using volumetric modulated arc therapy (VMAT) and simultaneous integrated boost (SIB) during a short course palliative accelerated radiotherapy. METHODS: A patient with a large symptomatic chordoma infiltrating the right gluteal region was selected. A modified SIB treatment was implemented to irradiate the central volume of the tumor (boost target volume, BTV) up to 10 Gy/fraction in a dose escalation trial while maintaining the remaining tumor volume (planning target volume, PTV) and the surrounding healthy tissues within 5 Gy/fraction in twice daily fractions for two consecutive days...

Introduction and background: Second-line treatment of platinum-resistant relapsed/metastatic (R/M) head and neck cancer (HNC) is a currently unmet clinical need. Clinical trials showed improvement in overall survival and quality of life of R/M-HNC patients treated with anti-PD-1 regardless of the number of prior chemotherapy lines; however, the percentage of long-term survivors remains limited.This study aims to test the hypothesis that attacking the tumor microenvironment at multiple levels can increase immunogenicity of R/M-HNC without worsening the safety profile of immune checkpoint inhibitors...

PURPOSE: We previously reported preventive and therapeutic effects of Smad7, a multifunctional protein, on radiation-induced mucositis in mice without promoting human oral cancer cell survival or migration in vitro. The current study aims to determine whether a Smad7-based biologic can treat existing oral mucositis during radiotherapy for oral cancer and whether this treatment compromises RT-induced cancer cell killing in neighboring oral cancer. EXPERIMENTAL DESIGN: We transplanted human oral cancer cells into the tongues of mice and applied craniofacial irradiation to simultaneously kill tumor cells and induce oral mucositis, thus modeling RT and mucositis in oral cancer patients...

Intensity-modulated radiation therapy is recommended in anal squamous cell carcinoma treatment and is increasingly used in rectal cancer. It adapts the dose to target volumes, with a high doses gradient. Intensity-modulated radiation therapy allows to reduce toxicity to critical normal structures and to consider dose-escalation studies or systemic treatment intensification. Image-guided radiation therapy is a warrant of quality for intensity-modulated radiation therapy, especially for successful delivery of the dose as planned...

PURPOSE: Day-to-day shape variation in the rectum CTV results in considerable geometric uncertainties during rectal cancer radiotherapy. To ensure coverage a large CTV-to-PTV margin is required. The purpose of this study was to increase the accuracy of treatment delivery by building a population based library of planning CTVs for rectal cancer patients and to evaluate its potential for rectum PTV margin and PTV volume reduction. METHODS: Analysis was done retrospectively on 33 early-stage rectal cancer patients with daily repeat CTs who received short-course pre-operative radiotherapy in 5 fractions of 5 Gy...

Metastases with soft tissues invasion, impending fractures or spinal cord compression (complicated bone metastases) represent a common clinical problem in advanced cancers and frequently lead to deterioration of patients' quality of life (QoL). A phase I-II study was planned to define the maximum tolerated dose (MTD) of a short-course radiotherapy (RT) and its efficacy in palliation of complicated bone metastases. A phase I trial was designed with three dose-escalation steps: 16, 18, and 20 Gy. Total dose at each level was delivered in 2 days, twice daily...

BACKGROUND: Neoadjuvant chemotherapy (NAC) allows earlier treatment of rectal cancer micro-metastases but is not standard of care. There are currently no biomarkers predicting long-term progression-free survival (PFS) benefit from NAC. PATIENTS AND METHODS: In this single arm phase II trial, patients with non-metastatic magnetic resonance imaging (MRI)-defined operable rectal adenocarcinoma at high risk of post-operative metastatic recurrence, received 8 weeks of oxaliplatin/fluorouracil NAC then short-course preoperative radiotherapy (SCPRT) before immediate surgery...

Thirty percent of patients with head and neck cancer are over 70 years. Radiotherapy approach in elderly is a challenge. On one hand, radiotherapy side effects, as well as the number of sessions required, could be a burden. On the other hand, omission of local treatment is not an option due to the symptoms of the tumor. Patients in good general condition may receive standard fractionnated radiotherapy. For frail patients unsuitable for standard fractionated radiotherapy, more convenient shorter course of radiotherapy are commonly used...

BACKGROUND: Although radical gastrectomy with D2 lymph node dissection has become the standard surgical approach for locally advanced gastric cancer, patients still have a poor prognosis after operation. Previously, we proposed laparoscopic distal gastrectomy (D2 lymphadenectomy plus complete mesogastrium excision [D2 + CME]) as an optimized surgical procedure for locally advanced gastric cancer. By dissection along the boundary of the mesogastrium, D2 + CME resected proximal segments of the dorsal mesogastrium completely with less blood loss, and it improved the short-term surgical outcome...

BACKGROUND: Lateral nodal disease in rectal cancer remains a subject of debate and is treated differently in the East and the West. The predictive value of lateral lymph node and MRI-detected extramural vascular invasion (mrEMVI) features on oncological outcomes was assessed in this study. METHODS: In this retrospective cohort study, data on patients with cT3-4 rectal cancer within 8 cm from the anal verge were considered over a 5-year period (2009-2013). Lateral lymph node size, malignant features and mrEMVI features were evaluated and related to oncological outcomes...
