NPC-0501 trial on the value of changing chemoradiotherapy sequence, replacing 5-fluorouracil with capecitabine, and altering fractionation for patients with advanced nasopharyngeal carcinoma.

Background: A current recommendation for the treatment of patients with locoregionally advanced nasopharyngeal carcinoma (NPC) is conventional fractionated radiotherapy (RT) with concurrent cisplatin followed by adjuvant cisplatin and 5-fluorouracil (PF). This randomized NPC-0501 trial evaluated the therapeutic effect of changing to an induction-concurrent sequence or accelerated-fractionation sequence, and/or replacing 5-fluorouracil with capecitabine (X).

Methods: Patients with American Joint Committee on Cancer/International Union Against Cancer stage III to stage IVB NPC initially were randomly allocated to 1 of 6 treatment arms (6-arm full-randomization cohort).

Prediction model for short-term mortality after palliative radiotherapy for patients having advanced cancer: a cohort study from routine electronic medical data.

We developed a predictive score system for 30-day mortality after palliative radiotherapy by using predictors from routine electronic medical record. Patients with metastatic cancer receiving first course palliative radiotherapy from 1 July, 2007 to 31 December, 2017 were identified. 30-day mortality odds ratios and probabilities of the death predictive score were obtained using multivariable logistic regression model.

The Value of Prognostic Nutritional Index in Follicular Lymphoma.

Objectives: Previous studies reported that prognostic nutritional index (PNI), a marker of host inflammatory and nutritional status, is associated with prognoses in a number of cancer types. Thus, we investigated PNI at diagnosis as a prognostic factor in FL.

Methods: We reviewed FL patients in Tuen Mun Hospital, Hong Kong from 2000 to 2014 (n=88).

Combined stereotactic body radiotherapy and trans-arterial chemoembolization as initial treatment in BCLC stage B-C hepatocellular carcinoma.

Purpose: We retrospectively evaluated the efficacy and safety of stereotactic body radiotherapy (SBRT) combined with trans-arterial chemoembolization (TACE) as initial therapy in Barcelona Clinic Liver Cancer (BCLC) system stage B-C hepatocellular carcinoma (HCC).

Patients And Methods: Seventy-two patients received a single dose of TACE followed by SBRT 4 weeks later. All patients had tumor sizes ≥5 cm, at least 700 ml of disease-free liver, Child-Pugh (CP) score ≤ B7 and tumor nodules ≤5.

Analysis of Plasma Epstein-Barr Virus DNA in Nasopharyngeal Cancer After Chemoradiation to Identify High-Risk Patients for Adjuvant Chemotherapy: A Randomized Controlled Trial.

Purpose The contribution of adjuvant chemotherapy after chemoradiation therapy (CRT) in nasopharyngeal cancer (NPC) remains controversial. Plasma Epstein-Barr virus (EBV) DNA is a potential biomarker of subclinical residual disease in NPC. In this prospective, multicenter, randomized controlled trial, we used plasma EBV DNA to identify patients with NPC at a higher risk of relapse for adjuvant chemotherapy.

Throwing the dart blind-folded: comparison of computed tomography versus magnetic resonance imaging-guided brachytherapy for cervical cancer with regard to dose received by the 'actual' targets and organs at risk.

Purpose: Computed tomography (CT) is inferior to magnetic resonance imaging (MRI) in cervical tumor delineation, but similar in identification of organs at risk (OAR). The trend to over-estimate high-risk and low-risk clinical target volume (HRCTV, IRCTV) on CT can lead to under-estimation of dose received by 90% (D) of the 'actual' CTV. This study aims to evaluate whether CT-guided planning delivers adequate dose to the 'actual' targets while spares the OAR similarly.

Survival analysis of malignant epidural spinal cord compression after palliative radiotherapy using Tokuhashi scoring system and the impact of systemic therapy.

Background: Previous studies have shown similar clinical outcomes of both single and multi-fraction (Fr) radiation therapy among malignant epidural spinal cord compression (MSCC) patients with poor prognosis; whereas, patients expected to have longer survival may require long-course radiotherapy to prevent local failure. However, such a poor prognosis risk group has not yet been clearly identified for use in daily clinical practice. We examined if the known predictive Tokuhashi scoring system could be adapted in MSCC patients treated with palliative radiation therapy.

Outcome of neoadjuvant chemoradiation in MRI staged locally advanced rectal cancer: Retrospective analysis of 123 Chinese patients.

Background: For advanced rectal cancer with involved or threatened mesorectal fascia (MRF), current standard is pre-operative long course chemoradiotherapy (PLCRT) with either capecitabine or 5-fluorouracil (5-FU). However, few Chinese data on its clinical outcome are available, especially for those with pelvic MRI staging.

Methods: Between Jan-2009 and Oct-2014, 123 consecutive patients with biopsy proven adenocarcinoma of rectum, all with pelvic MRI staging, selected for PLCRT after multi-disciplinary team discussion were recruited.

Aspirin and risk of multiple myeloma in adults: A systematic review and meta-analysis.

Multiple myeloma is a relatively uncommon plasma cell malignancy. Preclinical and clinical studies have suggested that aspirin might modify the risk of multiple myeloma. We performed a systematic review and meta-analysis of studies to examine the association between regular aspirin use and risk of multiple myeloma.

The Role of Radiotherapy in Early-stage Primary Diffuse Large B-Cell Lymphoma of the Waldeyer Ring: A Retrospective Cohort Study.

Objectives: The role of radiotherapy (RT) in improving survival of patients with diffuse large B-cell lymphoma (DLBCL) of the Waldeyer ring (WR) remains controversial. Therefore, this retrospective cohort study aimed to determine the role of RT in the treatment of DLBCL of the WR as well as the effects of associated covariates.

Materials And Methods: Patients (n=35) with stage I to II DLBCL of the WR who underwent treatment at our center between 1994 and 2010 were retrospectively investigated.

Severe ileitis associated with capecitabine: Two case reports and review of the literature.

Capecitabine is a commonly used anticancer drug, which has been associated with adverse events, including skin and gastrointestinal symptoms, such as vomiting and diarrhea. We herein present treated two rare cases of capecitabine-associated ileitis. In one of the patients, ileitis occurred during combination chemotherapy for metastatic colon cancer, despite previous good tolerance to this drug; the other patient developed ileitis following adjuvant single-agent treatment.

Lipiodol versus diaphragm in 4D-CBCT-guided stereotactic radiotherapy of hepatocellular carcinomas.

Purpose: The purpose of this work was to investigate the potential of lipiodol as a direct tumor surrogate alternative to the diaphragm surrogate on four-dimensional cone-beam computed tomography (4D-CBCT) image guidance for stereotactic radiotherapy of hepatocellular carcinomas.

Methods: A total of 29 hepatocellular carcinomas (HCC) patients treated by stereotactic radiotherapy following transarterial chemoembolization (TACE) with homogeneous or partial defective lipiodol retention were included. In all, 4-7 pretreatment 4D-CBCT scans were selected for each patient.

Current controversies in radiotherapy for nasopharyngeal carcinoma (NPC).

Radiotherapy has a good track record in the treatment of NPC, yet the late toxicity profile and local failure rate for locally advanced disease remain a concern. Modern RT techniques incorporating IMRT and IGRT have widened our potential in treating NPC more effectively, and shall be regarded as the standard of care. Out of the various dose fractionation regimens in IMRT, 70 Gy in 35 fractions or the mini-SIB proves to be safe in combination with chemotherapy, but any further attempt of dose escalation must be tried out with extreme caution to avoid severe toxicities.

Nasopharyngeal intracavitary brachytherapy: the controversy of T2b disease.

Background: Locally persistent nasopharyngeal carcinoma (NPC) carries an increased risk of local failure if additional treatment is not given. It has been shown that intracavitary brachytherapy is effective in the treatment of patients with T1 and T2a NPC, although its role in the treatment of T2b disease had remained uncertain. The objectives of the current study were to evaluate the outcomes of patients with T2b, locally persistent NPC who were treated with high-dose-rate (HDR) intracavitary brachytherapy and to explore whether routine brachytherapy boost could improve the local control of patients who had T2b NPC at initial diagnosis.
