In this work, we brought together two existing clinical techniques used in cancer treatment-X-ray radiation and photodynamic therapy (PDT), whose combination termed X-PDT uniquely allows PDT to be therapeutically effective in deep tissue. To this end, we developed mitochondrially targeted biodegradable polymer poly(lactic--glycolic acid) nanocarriers incorporating a photosensitizer verteporfin, ultrasmall (2-5 nm) gold nanoparticles as radiation enhancers, and triphenylphosphonium acting as the mitochondrial targeting moiety. The average size of the nanocarriers was about 160 nm. Read More

A 78-year-old man was referred for investigation of prostate cancer following incidental uptake on 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET). Despite normal PSA and benign digital rectal exam, he was referred for consideration of trans-perineal biopsy to exclude prostate cancer. It was only on review of imaging that it became clearly apparent that the 18F-FDG uptake was due to urinary tracer pooling in a trans-urethral resection cavity. Read More

Introduction: Anus-preserving surgery for a large rectal gastrointestinal stromal tumor (GIST) may be difficult because of the location of the tumor in the pelvis. Therefore, rectal GIST might require extensive surgery, such as abdominoperineal resection.

Relapsing or far advanced rectal and anal cancers remain difficult to treat and require interdisciplinary approaches. Due to modern standard protocols all patients receive irradiation and neoadjuvant chemotherapy-and in case of a relapse a second irradiation-rendering the surgical site prone to surgical site infections and oftentimes long lasting sinus and septic complications after exenteration in the pelvis. Despite an improved overall survival rate in these patients the downside of radical tumor surgery in the pelvis is a major loss of quality of life, especially in women when parts of the vagina need to be resected.

Neuroendocrine neoplasms (NENs) comprise a heterogeneous group of tumours, which can be classified into neuroendocrine tumours (NETs), neuroendocrine carcinomas (NECs) and mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs). To date, there is no consensus regarding the optimal therapy, which usually depends on the primary location and classification, according to morphological features of differentiation and proliferation rates. Nevertheless, multidisciplinary strategies combining medical treatments and locoregional strategies have yielded better efficacy results. Read More

At the time of diagnosis, approximately 15%-20% of patients with rectal cancer (RC) presented synchronous liver metastasis (SLM), which is the most common cause of death in patients with RC. Therefore, preoperative, noninvasive, and accurate prediction of SLM is crucial for personalized treatment strategies. Recently, radiomics has been considered as an advanced image analysis method to evaluate the neoplastic heterogeneity with respect to diagnosis of the tumor and prediction of prognosis. Read More

Purpose: Obesity, neoadjuvant-radiotherapy, tumour proximity to the anal verge and previous abdominal surgery are factors that might increase the intra-operative difficulty of laparoscopic rectal cancer surgery. However, whether patients with these 'high-risk' characteristics are subject to worse short- or long-term outcomes is debated. The aim of this study is to examine the short- and long-term clinical and oncological outcomes of patients receiving laparoscopic rectal surgery with any of these high-risk characteristics and compare them with patients that do not possess any of these high-risk features.

Background: Preoperative radiochemotherapy (RCT) is recommended in France prior to total mesorectal excision in patients with mid or low locally advanced rectal cancer (LARC) (cT3/T4 and/or N+) because it has been shown to improve local control. Preoperative RCT has also disadvantages including the absence of proven impact on metastatic recurrence and the risk of late side effects on bowel and genitourinary function. In patients with primarily resectable LARC, preoperative systemic chemotherapy without pelvic irradiation could be used as an alternative to RCT. Read More
