Background Immediate breast reconstruction (IBR) is often deferred, when postmastectomy radiotherapy (PMRT) is anticipated, due to high complication rates. Nonetheless, because of robust data supporting improved health-related quality of life associated with reconstruction, physicians and patients may be more accepting of tradeoffs. The current study explores national trends of IBR utilization rates and methods in the setting of PMRT, using the National Cancer Database (NCDB). The study hypothesis is that prosthetic techniques have become the most common method of IBR in the setting of PMRT...

Radio- and chemo-resistance represent major obstacles in the therapy of non-small-cell lung cancer (NSCLC) and the underlying molecular mechanisms are not known. In the present study, during induction of radio- or chemo-resistance in NSCLC cells, dynamic analyses revealed that decreased expression of let-7 induced by irradiation or cisplatin resulted in increased expression of its target gene LIN28, and increased expression of LIN28 then contributed to further decreased expression of let-7 by inhibiting its maturation and biogenesis...

BACKGROUND: Desmoplastic Small Round Cell Tumor (DSRCT) is a rare disease affecting predominantly children and young adults and for which the benefit of hyperthermic intraperitoneal chemotherapy (HIPEC) after complete cytoreductive surgery (CCRS) remains unknown. METHODS: To identify patients with DSRCT without extraperitoneal metastases (EPM) who underwent CCRS between 1991 and 2015, a retrospective nation-wide survey was conducted by crossing the prospective and retrospective databases of the French Network for Rare Peritoneal Malignancies, French Reference Network in Sarcoma Pathology, French Sarcoma Clinical Network and French Pediatric Cancer Society...

Real-time monitoring and amendment of patient position is important for the radiotherapy. However, using electronic portal imaging device (EPID) and cone beam computer tomography (CBCT) in the clinical practice generate different degrees of delay, so that they cannot achieve the purpose of real-time application. Meanwhile, a few products come with the function of the real-time monitoring and amendment, such as CyberKnife, which is too expensive for the common people. The objective of this study is to develop and test a novel independent system to monitor treatment center and amend the position of patient, which is applicable to most accelerators, based on binocular location...

The biological cause of clinically observed variability of normal tissue damage following radiotherapy is poorly understood. We hypothesized that machine/statistical learning methods using single nucleotide polymorphism (SNP)-based genome-wide association studies (GWAS) would identify groups of patients of differing complication risk, and furthermore could be used to identify key biological sources of variability. We developed a novel learning algorithm, called pre-conditioned random forest regression (PRFR), to construct polygenic risk models using hundreds of SNPs, thereby capturing genomic features that confer small differential risk...

The treatment of cervical cancers according to FIGO staging is well defined. For FIGO stage IB2 or more, chemoradiotherapy followed by uterovaginal brachytherapy boost is the standard treatment. Surgery is the preferred choice for less advanced tumors. However, most French institutions propose preoperative brachytherapy followed by hysterectomy with pelvic lymphadenectomy for FIGO stage IB1 tumors over 2cm. Brachytherapy is also used for the boost after adjuvant pelvic external beam radiotherapy. Tridimensional dosimetry with optimization allows better treatment planning, delivering high doses to target volumes with limited irradiation to the organs at risk...

OBJECTIVE: To evaluate the clinical, radiological and histological factors that can predict local recurrence of fibromatosis. METHODS: A retrospective study was conducted on 51 patients diagnosed with fibromatosis in this hospital from 1983 to 2014. The mean follow-up was 83 months. A study was made of the clinical parameters, location, depth, size, surgical margins, and proliferation index (Ki-67). An evaluation was also made of the risk of recurrence depending on the adjuvant treatment and the relationship between treatment and patient functionality...

BACKGROUND: Erectile dysfunction remains the most common side effect from radical treatment of localized prostate cancer. We hypothesized that the use of vessel-sparing radiotherapy, analogous to the functional anatomy approach of nerve-sparing radical prostatectomy (RP), would improve erectile function preservation while maintaining tumor control for men with localized prostate cancer. OBJECTIVE: To determine erectile function rates after vessel-sparing radiotherapy...

BACKGROUND: Pediatric nonrhabdomyosarcoma soft tissue sarcomas (NRSTS) may rarely occur in visceral tissues, and little is known about their clinical history. The present study retrospectively analyzed a group of patients prospectively registered in Italian pediatric protocols conducted between 1979 and 2004. METHODS: Inclusion criteria for the study were as follows: a pathological diagnosis of "adult-type NRSTS," arising at visceral sites (lung-pleurae, liver, kidney, and mesentery-bowel); age under 18 years; no previous treatment except for primary surgery; available clinical data; and written consent...

Epithelioid sarcoma (ES) is a very rare soft-tissue sarcoma with a high tendency of recurrence and metastasis. We analyzed clinical features of ES and aimed to identify the potential role of radio- and chemotherapy in ES. Fifty-five patients diagnosed with ES between 1997 and 2014 were enrolled from seven tertiary hospitals in Korean Cancer Research Group. The clinical variables were retrospectively reviewed and analyzed. Forty-six (84%) patients underwent surgical resection of ES, and among them, 27 experienced recurrence...

Pancreatic cancer is a type of common malignant tumors with high occurrence in the world. Most patients presented in clinic had pancreatic cancer at advanced stages. Furthermore, chemotherapy or radiotherapy had very limited success in treating pancreatic cancer. Complementary and alternative medicines, such as natural products/herbal medicines, represent exciting adjunctive therapies. In this review, we summarize the recent advances of using natural products/herbal medicines, such as Chinese herbal medicine, in combination with conventional chemotherapeutic agents to treat pancreatic cancer in preclinical and clinical trials...

: Lung cancer resists radiation therapy, making it one of the deadliest forms of cancer. Here we show that human lung cancer cell lines can be rendered sensitive to ionizing radiation (IR) by RNAi knockdown of Cterminus of Hsc70-interacting protein (CHIP/STUB1), a U-box-type E3 ubiquitin ligase that targets a number of stress-induced proteins. Mechanistically ubiquitin-dependent degradation of the cyclin-dependent kinase (CDK) inhibitor p21 protein is reduced by CHIP knockdown, leading to enhanced senescence of cells in response to exposure to IR...

Radiation-induced proctitis (RIP) is the most common clinical adverse effect for patients receiving radiotherapy as part of the standard course of treatment for ovarian, prostate, colon, and bladder cancers. RIP limits radiation dosage, interrupts treatment, and lowers patients' quality of life. A prophylactic treatment that protects the gastrointestinal tract from deleterious effects of radiotherapy will significantly improve patient quality of life and may allow for higher and more regular doses of radiation therapy...
