BACKGROUND: Complete tumour response (pCR) to neo-adjuvant chemo-radiotherapy for rectal cancer is associated with a reduction in local recurrence and improved disease-free and overall survival, but is achieved in only 20-30% of patients. Drug repurposing for anti-cancer treatments is gaining momentum, but the potential of such drugs as adjuncts, to increase tumour response to chemo-radiotherapy in rectal cancer, is only just beginning to be recognised. METHODS: A systematic literature search was conducted and all studies investigating the use of drugs to enhance response to neo-adjuvant radiation in rectal cancer were included...

BACKGROUND/AIMS: The neoadjuvant therapy for locally advanced rectal cancer has been changed from radiotherapy (RT) to chemoradiotherapy (CRT). This study is aimed at evaluating the benefit of CRT in patients with stage II or III lower rectal cancer, with regard to the impact on recurrence. METHODS: A total of 474 patients with clinical stage II or III lower rectal cancer who received either preoperative RT (n = 221) or CRT (n = 253) followed by total mesorectal excision were identified from our institutional database...

BACKGROUND: Recently, nomograms have been used as models for risk prediction in malignant tumor because they can predict the outcome of interest for a certain individual based on many variables. This study aimed to establish an effective prognostic nomogram for osteosarcoma based on the clinicopathological factors and microRNA-203. RESULTS: The results showed that miR-203 expression was significantly lower in osteosarcoma tissues compared with the corresponding adjacent tissues (P < 0...

This pilot study explored predictors of adherence to exercise during and after neoadjuvant chemoradiotherapy (NACRT) in rectal cancer patients. Eighteen rectal cancer patients were prescribed three supervised aerobic exercise sessions/week during NACRT followed by ≥150 min/week of unsupervised aerobic exercise after NACRT. Although not statistically significant, adherence to supervised exercise during NACRT was meaningfully better for patients who were women (d = .82; P = .12), younger (d = -.62; P = ...

BACKGROUND: Anastomotic leakage following colorectal resection remains one of the most significant complications with relevant morbidity and mortality. There is evidence that a higher number of stapler firings for rectal division can affect the leak rate in double stapling anastomosis. However, there are no data concerning compression anastomosis. We present our institutional experience addressing this issue. DESIGN: This is a retrospective review of a prospective institutional database of patients undergoing colonic and rectal resection for benign and malignant indications between January 2008 and December 2014 at the surgical department of the St...

Here, we report an unusual case of sarcomatoid carcinoma mimicking extraskeletal osteosarcoma that manifested as recurrent rectal cancer. Five years earlier, a 76-year-old male patient had undergone neoadjuvant chemoradiotherapy followed by a laparoscopic low anterior resection due to adenocarcinoma of the rectum. He was admitted because of pain in the anus and left hip. He underwent abdominal computed tomography that revealed a newly developed left perirectal mass with gluteus maximus invasion measuring up to 8 cm, and therefore, an abdominoperineal resection was performed...

The management of bronchopleural fistulas can be challenging. The initial treatment is usually conservative, but operative intervention with transposition of vascularized pedicled flaps may be required in refractory cases. We present the case of a 67-year-old man with stage IIIa squamous cell carcinoma of the lung who underwent a lower and middle bilobectomy after receiving neoadjuvant chemoradiation. His postoperative course was complicated by empyema and a bronchopleural fistula. Because of difficulty accessing the fistula, endobronchial-guided vascularized tissue flaps were successfully used to close the fistula...

Perioperative chemotherapy is likely to improve survival in both the neoadjuvant and the adjuvant setting. Therefore, it is an integral part of the modern treatment of patients with muscle-invasive urothelial bladder cancer. All patients who are suitable for cisplatin-based chemotherapy should be involved in a corresponding concept.Cisplatin-based combinations are standard regimens in the perioperative and palliative systemic treatment of urothelial cancer. Carboplatin is only an inferior substitute for "unfit" patients in the palliative treatment situation...

Treatment for locally-advanced rectal cancer (LARC) typically consists of neoadjuvant chemoradiation followed by total mesorectal excision. Recently, there has been growing interest in non-operative management for patients who are medically-inoperable or wish to avoid surgical morbidity and permanent colostomy. Approximately 50% of patients who receive pre-operative neoadjuvant chemoradiation develop some degree of pathologic response. Approximately 10-20% of patients are found to have a complete pathologic response, a finding which has frequently been shown to predict better clinical outcomes, including local-regional control, distant metastasis and survival...

PURPOSE: The potential of diffusion weighted imaging (DWI) in assessing pathologic response and surgical margins in locally advanced breast cancer patients (n=38) undergoing neoadjuvant chemotherapy was investigated. METHODS: DWI was performed at pre-therapy (Tp0), after I (Tp1) and III (Tp3) NACT at 1.5T. Apparent diffusion coefficient (ADC) of whole tumor (ADCWT), solid tumor (ADCST), intra-tumoral necrosis (ADCNec) was determined. Further, ADC of 6 consecutive shells (5mm thickness each) including tumor margin to outside tumor margins (OM1 to OM5) was calculated and the data analyzed to define surgical margins...

BACKGROUND: The Ewing sarcoma family of tumors (ESFT) is a rare but curable bone neoplastic entity. The current standard of care involves chemotherapy and local disease control with surgery or radiation regardless of the extent of disease at presentation. Data that document the effectiveness of the current approach in the adult patient population are limited. METHODS: We performed a retrospective review including all ESFT patients older than 19 years of age who received systemic therapy between January 2002 and December 2013 at our institution...

INTRODUCTION: The current standard of care for ovarian cancer is optimal cytoreduction with adjuvant chemotherapy based on a platinum/taxane combination. Although the response rate to this therapy is high, most patients ultimately relapse. Response to second-line therapy and prognosis are linked to the platinum-free interval (PFI); when both improve, the PFI increases. As a result, there is an increasing interest in the PFI extension strategies including platinum-free combinations. CASE PRESENTATION: A 50-year-old postmenopausal woman presented with ovarian serous carcinoma with peritoneal carcinomatosis...

We report a rare case of squamous cell carcinoma (SCC) in bladder diverticulum producing granulocyte colony stimulating factor (G-CSF). A 59-year-old man complaining of hematuria and right hip pain was admitted with a large cancer in the bladder diverticulum. His laboratory data showed leukocytosis of 20,100/ μ l (neutrophils : 92%) with an elevated G-CSF of 76. 6 pg/ml in the peripheral blood. After neoadjuvant chemotherapy (gemcitabine and cisplatin), radical cystectomy was performed to normalize serum leukocytosis and G-CSF...

Discrimination of pancreatic ductal adenocarcinoma (PDAC) from chronic pancreatitis (CP) or peritumoral inflammation is challenging, both at preoperative imaging and during surgery, but it is crucial for proper therapy selection. Tumor-specific molecular imaging aims to enhance this discrimination and to help select and stratify patients for resection. We evaluated various biomarkers for the specific identification of PDAC and associated lymph node metastases. Using immunohistochemistry (IHC), expression levels and patterns were investigated of integrin αvβ6, carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5), Cathepsin E (Cath E), epidermal growth factor receptor (EGFR), hepatocyte growth factor receptor (c-MET), thymocyte differentiation antigen 1 (Thy1), and urokinase-type plasminogen activator receptor (uPAR)...

INTRODUCTION: Acellular dermal matrix (ADM) assisted implant-based breast reconstruction (IBBR) has grown in popularity over traditional submuscular techniques. Numerous human, bovine or porcine derived ADMs are available with the type used varying considerably worldwide. Yet, comparative evidence for the efficacy of different ADMs particularly xenogenic is limited. This study directly compares early outcomes of porcine (Strattice™) and bovine (Surgimend™) ADMs in IBBR. METHOD: Retrospective study of sequential experience of immediate IBBR using Strattice or Surgimend ADM...
