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...

BACKGROUND/AIM: Radiotherapy is not routinely used in metastatic pancreatic ductal adenocarcinoma (PDAC). We conducted a phase I study to investigate concurrent chemoradiotherapy (CCRT) followed by chemotherapy. MATERIALS AND METHODS: S-1 was administered at 50-70 mg/m2 /day with radiotherapy in 2.5-3.6 Gy/day for 10-12 fractions. After CCRT, gemcitabine (1,000 mg/m2 on days 1 and 15) and S-1 (60-100 mg/day on days 1-7 and 15-21), were administered in a 4-week cycle...

BACKGROUND/AIM: Metastases involving the adrenal glands can be treated surgically or with radiation therapy. Retrospective studies indicate that radiotherapy for this indication is safe, well-tolerated and associated with symptom palliation and good local control. We conducted this analysis to report on patterns and outcomes of patients with adrenal metastases treated with hypo- or conventionally fractionated image-guided radiotherapy. PATIENTS AND METHODS: Patients with adrenal metastases from solid tumors treated at our department between 01/2010-12/2017 were reviewed...

PURPOSE: Research on symptom clusters is a newly emerging field in oncology; however, little evidence regarding symptom clusters in head and neck cancer (HNC) is currently available. To clarify this under-researched area, we investigated symptom clusters among patients with HNC treated with surgery and postoperative radiotherapy. We also examined the pattern of symptom clusters throughout the treatment course. METHOD: A convenience sample of 100 patients with HNC was recruited in the Ear, Nose, and Throat unit of a medical center in Taiwan...

Locally advanced rectal cancer (LARC) carries higher risks of local and distant recurrence when treated with surgical resection alone. Multiple treatment strategies have been investigated to reduce recurrence risk and improve survival. Currently, there are 3 primary strategies for managing LARC: (1) preoperative long-course radiotherapy (RT) combined with radiosensitizing chemotherapy, which is better tolerated than postoperative chemoradiotherapy and provides tumor downstaging and improved pathologic complete response (pCR), followed by postoperative chemotherapy; (2) preoperative short-course RT alone as an alternative strategy for reducing the risk of local recurrence, followed by adjuvant postoperative chemotherapy; and (3) total neoadjuvant therapy with induction chemotherapy followed by chemoradiotherapy to improve pCR and reduce the difficulty of delivering chemotherapy in the postoperative setting...

BACKGROUND AND PURPOSE: The role of preoperative short-course radiotherapy (SCRT) in rectal cancer treatment, when compared to long-course radiochemotherapy (LCRT), is still controversial. Thus the meta-analysis with trial sequential analysis (TSA) was performed to evaluate the long-term survival of SCRT and LCRT as therapeutic regimens for locally advanced rectal cancer. MATERIAL AND METHODS: PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched up to August 2017 for eligible studies...

Methionine dependency describes the characteristic rapid in vitro death of most tumor cells in the absence of methionine. Combining chemotherapy with dietary methionine deprivation (MDD) at tolerable levels has vast potential in tumor treatment; however, it is limited by MDD-induced toxicity during extended deprivation. Recent advances in imaging and irradiation delivery have created the field of stereotactic body radiotherapy (SBRT), where fewer large-dose fractions delivered in less time result in increased local-tumor control, which could be maximally synergistic with an MDD short course...

Purpose: Salvage radiation therapy (RT) is a potentially curative treatment option for head and neck sarcomas (HNS) that did not respond to previous treatment(s). We report the first clinical experience of carbon ion radiotherapy (CIRT) for salvage treatment of locally recurrent (LR) or RT-induced secondary HNS after surgery and/or radiotherapy. Methods and Materials: A retrospective analysis of the ongoing prospective data registries from the Shanghai Proton and Heavy Ion Center was conducted. Patients with LR-HNS who underwent surgery and/or RT and those with RT-induced second primary HNS were included...

Background: It is unclear whether emergency weekend colon and rectal cancer surgery are associated with worse outcomes (ie, weekend effect) because previous studies mostly used administrative data, which may insufficiently adjust for case-mix. Materials and Methods: Prospectively collected data from the 2012-2015 Dutch ColoRectal Audit (n=5,224) was used to examine differences in 30-day mortality and severe complication and failure-to-rescue rates for emergency weekend (Saturday and Sunday) versus Monday surgery, stratified for colon and rectal cancer...

BACKGROUND: The safety and efficacy of preoperative short-course radiotherapy had been verified in rectal cancer. However, the timing of surgery after radiation had not been well defined. Thus, we performed this meta-analysis to compare the interval time of surgery after short-course radiotherapy in rectal cancer: immediate surgery (<4 weeks) vs delayed surgery (>4 weeks). METHODS: We searched the PubMed, EMBASE, MEDLINE, and Cochrane Library database. The primary endpoints were survival rates and pathological outcomes, and the second endpoints included sphincter preservation rate, R0 resection rate and postoperative complications...

RATIONALE: This combination of fluticasone propionate (FP) and the long-acting β2-agonist salmeterol (Salm) can control the symptoms of asthma and COPD better than FP or Salm on their own and better than the combination of inhaled corticosteroids plus montelukast. FP/Salm has been shown to control symptoms of asthma and COPD better than a double dose of inhaled steroids. The patient in our report had a history of COPD, and suffered relapse of RP when given only steroids. It is possible that COPD history helps explain this patient's more difficult treatment course...

BACKGROUND: Radical resection by multivisceral resection of colorectal T4 tumours is important to reduce local recurrence and improve survival. Oncological safety of laparoscopic resection of T4 tumours is controversial. However, robot-assisted resections might have advantages, such as 3D view and greater range of motion of instruments. The aim of this study is to evaluate the initial results of robot-assisted resection of T4 rectal and distal sigmoid tumours. METHODS: This is a cohort study of a prospectively kept database of all robot-assisted rectal and sigmoid resections between 2012 and 2017...
