AIM: Full thickness local excision after neoadjuvant chemoradiotherapy (CRT) for patients with rectal cancer and incomplete clinical response has been a treatment strategy for organ preservation. Follow up of these patients is challenging since anatomic distortion and postoperative changes may be clinically indistinguishable from tumor recurrence. Magnetic resonance imaging (MRI) may have a role in detecting recurrence. The aim of this study is to describe the MRI findings during follow-up in patients having local excision following CRT with and without local recurrence...

BACKGROUND: Head and neck cancers positive for human papillomavirus (HPV) are exquisitely radiosensitive. We investigated whether chemoradiotherapy with reduced-dose radiation would maintain survival outcomes while improving tolerability for patients with HPV-positive oropharyngeal carcinoma. METHODS: We did a single-arm, phase 2 trial at two academic hospitals in the USA, enrolling patients with newly diagnosed, biopsy-proven stage III or IV squamous-cell carcinoma of the oropharynx, positive for HPV by p16 testing, and with Zubrod performance status scores of 0 or 1...

A temporary stoma is often used in rectal cancer surgery to protect a distal anastomosis, which remains a major concern after rectal cancer surgery, particularly after low anterior resection. The temporary stoma is scheduled for closure. However, the optimal time of closure of the protecting stoma remains unclear because of sparse studies and data. We aimed to detect the efficacy between early and late temporary ileostomy closure in patients with rectal cancer during or after neoadjuvant chemoradiotherapy. We conducted a prospective, 2-group design between early and late ileostomy closure group in patients after rectal cancer surgery with temporary stoma...

For high-risk low-grade gliomas (LGGs), adjuvant radiotherapy (RT) with procarbazine/lomustine/vincristine (PCV) chemotherapy increases overall survival (OS) over RT alone. However, in practice, temozolomide (TMZ) is often used instead of PCV. Using the National Cancer Data Base (NCDB), we provide the first investigation of practice patterns and outcomes of chemoradiotherapy with single-agent chemotherapy (SAC, analogous to TMZ) or multi-agent chemotherapy (MAC, analogous to PCV) for LGG. Patients with high-risk Grade II LGGs were queried in the NCDB...

BACKGROUND: Considering that pneumonectomy itself is a disease, avoidance of pneumonectomy needs to be deliberated. Herein, we evaluated the role of neoadjuvant chemoradiotherapy for avoidance of pneumonectomy in patients with centrally located locally advanced non-small cell lung cancer. METHODS: Patients who underwent neoadjuvant chemoradiotherapy after being judged to require pneumonectomy by cancer board between 1997 and 2011 were retrospectively evaluated. RESULTS: Twelve patients, including 10 males and 2 females with median age 63...

In general, prognosis of stage IV non-small cell lung cancer is poor, and treatment is mostly palliative. However, oligometastatic disease is currently recognized as a specific entity with a better prognosis. We report a patient where combined chemoradiotherapy and salvage surgery led to extraordinary long-term survival.

Background: Concurrent chemoradiotherapy followed by adjuvant chemotherapy (CCRT-AC) has been established as the standard of care in locally advanced nasopharyngeal carcinoma (LA-NPC). The survival benefit of induction chemotherapy (ICT) for LA-NPC remains controversial. We analyzed the efficacy and feasibility of docetaxel, cisplatin and 5-fluorouracil (TPF) ICT followed by CCRT for LA-NPC with nodal Stage N2-3. Methods: We performed a retrospective analysis of 28 LA-NPC patients with nodal Stage N2-3 receiving induction TPF followed by CCRT (TPF group; n = 12) or CCRT-AC (CCRT group; n = 16) between October 2006 and May 2016...

Lots of controversies were found about the treatment in relation to radiation therapy (RT) for esophageal squamous cell carcinoma (ESCC). We designed a questionnaire of these controversies to do a pan-Chinese survey of radiation oncologists (ROs). For operable ESCC, 53% ROs chose surgery plus postoperative chemoradiotherapy (CRT), while 40% chose preoperative CRT plus surgery. For target volume of postoperative RT, most ROs (92%) would delineate tumor bed plus involved lymph nodes region before surgery. For definitive RT, most ROs (81%) would give patients higher RT dose to 60-65Gy...

PURPOSE: To define the role of immediate-early 5 (IER5) gene as a promising biomarker in predicting the radiosensitivity and prognosis of cervical cancer patients receiving cisplatin-based concurrent chemoradiotherapy (DDP-CCRT). RESULTS: Our investigations found that IER5 level was markedly elevated in cervical cancer patients after being treated with irradiation, which indicated IER5 was closely dose induced. By contrast, the correlation between IER5 and radiosensitivity cannot be confirmed by the present study...

Cancer stem cells (CSCs) have been hypothesized to initiate tumor growth and be resistant to chemoradiotherapy, and these processes appear to be closely related to CSC quiescence. Here, a CSC-like cell population with a high level of CD44 expression was obtained from the human gastric cancer cell lines MKN45 and MKN74. Using a PKH26-labeling retention assay, quiescent CSC-like cells with low levels of Ki67 and PCNA expression were found in spheres formed in serum-free medium, and exhibited resistance to drug and radiation treatments...

BACKGROUND: Esophageal cancer including squamous cell carcinoma (SCC) and adenocarcinoma represents 4% of all cancers in the United States. Patients with esophageal cancer frequently present with locally advanced disease, and about 40% of patients have evidence of metastatic disease on presentation. Common sites of metastasis include liver, lung and bone. Here, we present a rare case of colonic metastasis from primary esophageal SCC. CASE PRESENTATION: A 60-year-old Caucasian male with a history of 20-pack-year cigarette smoking received surgery and adjuvant chemoradiotherapy for locally advanced SCC of larynx...

BACKGROUND: To compare cumulative acute toxicity in head and neck cancer patients treated with concurrent chemoradiotherapy alone (CCRT) versus induction chemotherapy (IC) followed by CCRT (I/CCRT). METHODS: 77 patients underwent definitive CCRT (30 I/CCRT and 47 CCRT). Toxicity was graded using the Common Terminology Criteria for Adverse Events version 4.0. Using the TAME adverse event reporting system, short-term toxicity (T) scores were generated for IC (TIC), CCRT (TCCRT), total treatment duration (TRx), post-treatment period (TPT) and an overall score (Toverall) from treatment start to post treatment period...

(18)F-fluorodeoxyglucose PET/CT ((18)F-FDG-PET/CT) is widely applied in oncology for disease staging, assessment of therapy response, relapse diagnosis, follow-up and target volume delineation. In particular, it can detect early response during chemoradiotherapy (interim) because functional modifications usually precede morphological ones. This ability is crucial to the radiation oncologist for the management of patients, to avoid persisting with ineffective therapy - often leading toxicity - and to shift to potentially more effective alternatives...
