Optimizing the combination of chemotherapeutic drugs along with radiotherapy for extranodal NK/T-cell lymphoma.

Background: Extranodal natural killer/T-cell lymphoma (ENKTCL) has a unique treatment principle. However, the optimal combination of drugs along with radiotherapy (RT) is unknown.

Design: Retrospective cohort study.

Outcome and risk prediction of early progression in patients with extranodal natural killer/T cell lymphoma from the CLCG study.

Recently, progression-free survival at 24 months (PFS24) was defined as clinically relevant for patients with extranodal NK/T cell lymphoma. Herein, the clinical data from two independent random cohorts (696 patients each in the primary and validation datasets) were used to develop and validate a risk index for PFS24 (PFS24-RI), and evaluate its ability to predict early progression. Patients achieving PFS24 had a 5-year overall survival (OS) of 95.

Tracheoesophageal fistula closure after staged dose-escalated radiotherapy for esophageal squamous cell carcinoma: a case report.

An esophageal fistula can be caused by an esophageal tumor as well as the surgery, radiotherapy (RT), or chemoradiotherapy used to treat the tumor. The most dangerous complications are massive hemoptysis and asphyxia. This report describes a 58-year-old man with a >1-month history of dysphagia and hemoptysis.

Evidence of cure for extranodal nasal-type natural killer/T-cell lymphoma with current treatment: an analysis of the CLCG database.

Survival from extranodal nasal-type NK/T-cell lymphoma (ENKTCL) has substantially improved over the last decade. However, there is little consensus as to whether a population of patients with ENKTCL can be considered "cured" of the disease. We aimed to evaluate the statistical "cure" of ENKTCL in the modern treatment era.

Clinical characteristics, treatment, and survival of 30 patients with gastrointestinal natural killer/T-cell lymphoma.

Background: The gastrointestinal (GI) tract is the second most frequent extranasal involvement site for ENKTL. This study aimed to explore the clinicopathological features, treatment models, survival outcomes, and prognosis of gastrointestinal ENKTL (GI-ENKTL).

Methods: The clinical data of GI-ENKTL patients were extracted from the China Lymphoma Collaborative Group (CLCG) database and were analyzed retrospectively.

Characteristics and prognosis of distant metastasis after primary treatment for early-stage extranodal nasal-type natural killer/T-cell lymphoma from the China Lymphoma Collaborative Group database.

This study aimed to investigate the characteristics and prognosis of distant metastasis (DM) after primary treatment for early-stage extranodal nasal-type natural killer (NK)/T-cell lymphoma (ENKTCL). A total of 1619 patients from the China Lymphoma Collaborative Group database were retrospectively reviewed. The cumulative incidence of DM was assessed using Fine and Gray's competing risk analysis.

Progression-free survival at 24 months and subsequent survival of patients with extranodal NK/T-cell lymphoma: a China Lymphoma Collaborative Group (CLCG) study.

Limited evidence supports the use of early endpoints to evaluate the success of initial treatment of extranodal NK/T-cell lymphoma (ENKTCL) in the modern era. We aim to analyze progression-free survival at 24 months (PFS24) and subsequent overall survival (OS) in a large-scale multicenter cohort of patients. 1790 patients were included from the China Lymphoma Collaborative Group (CLCG) database.

Risk-based, response-adapted therapy for early-stage extranodal nasal-type NK/T-cell lymphoma in the modern chemotherapy era: A China Lymphoma Collaborative Group study.

We aimed to determine the survival benefits of chemotherapy (CT) added to radiotherapy (RT) in different risk groups of patients with early-stage extranodal nasal-type NK/T-cell lymphoma (ENKTCL), and to investigate the risk of postponing RT based on induction CT responses. A total of 1360 patients who received RT with or without new-regimen CT from 20 institutions were retrospectively reviewed. The patients had received RT alone, RT followed by CT (RT + CT), or CT followed by RT (CT + RT).

Validation of nomogram-revised risk index and comparison with other models for extranodal nasal-type NK/T-cell lymphoma in the modern chemotherapy era: indication for prognostication and clinical decision-making.

Derived from our original nomogram study by using the risk variables from multivariable analyses in the derivation cohort of 1383 patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL) who were mostly treated with anthracycline-based chemotherapy, we propose an easily used nomogram-revised risk index (NRI), validated it and compared with Ann Arbor staging, the International Prognostic Index (IPI), Korean Prognostic Index (KPI), and prognostic index of natural killer lymphoma (PINK) for overall survival (OS) prediction by examining calibration, discrimination, and decision curve analysis in a validation cohort of 1582 patients primarily treated with non-anthracycline-based chemotherapy. The calibration of the NRI showed satisfactory for predicting 3- and 5-year OS in the validation cohort. The Harrell's C-index and integrated Brier score (IBS) of the NRI for OS prediction demonstrated a better performance than that of the Ann Arbor staging system, IPI, KPI, and PINK.

Salvage radiotherapy in patients with local recurrent esophageal cancer after radical radiochemotherapy.

Purpose: The aim of this study was to evaluate the salvage radiotherapy outcome in patients with local recurrent esophageal cancer after radical radiochemotherapy (RCT).

Methods: A total of 114 patients with local recurrent esophageal squamous cell carcinoma after initial radical RCT were retrospectively analyzed. Fifty-five (55) patients belonged to the salvage radiotherapy group (SR group) and 59 patients to the non-salvage radiotherapy group (NSR group).

Literature analysis of radiotherapy for esophageal cancer in China.

Background And Objective: Many patterns of treatment have been used to treat esophageal carcinoma in the past years, however, an optimal treatment is still the key issue to be explored. Therefore, we analyzed the published literature about radiotherapy for esophageal cancer in recent 15 years in China, and observed the survival rate, local control rate, adverse events, and so on.

Methods: A total of 56 eligible papers about radiotherapy for esophageal squamous cell carcinoma published in Chinese core periodicals between 1994 and 2009 were selected.

The value of radiotherapy in patients with T1 and T2 breast cancer with one to three positive nodes after modified radical mastectomy.

Background And Objective: The role of adjuvant radiotherapy to the regional nodes in women with T1 to T2 breast cancer and one to three positive nodes is controversial. This study compared and analyzed the prognosis of patients with T1-T2 breast cancer with one to three positive nodes after modified radical mastectomy with or without postoperative radiotherapy.

Methods: The cases of 434 women patients with T1 to T2 breast cancer with one to three positive lymph nodes after modified radical mastectomy were reviewed, of which 196 patients received postoperative radiotherapy and 238 patients did not.

TGF-beta1 in serum and induced sputum for predicting radiation pneumonitis in patients with non-small cell lung cancer after radiotherapy.

Background And Objective: Research has confirmed that transforming growth factor-beta1 (TGF-beta1) is one of the cytokines related to radiation pneumonitis. But the level of TGF-beta1 in serum needed to predict radiation pneumonitis is still not clear. This study assessed the value of TGF-beta1 in both serum and induced sputum in predicting radiation pneumonitis, providing a reference for the radiotherapy of patients with non-small cell lung cancer (NSCLC).

[Association of single nucleotide polymorphism of MnSOD gene with carcinogenesis and development of esophageal squamous cell carcinoma].

Objective: To investigate the association of single nucleotide polymorphism (SNP) of manganese superoxide dismutase (MnSOD) gene with carcinogenesis and progression of esophageal squamous cell carcinoma.

Methods: The MnSOD9 T-->C SNP was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 103 patients with esophageal squamous cell carcinoma and 195 healthy controls.

Results: A significant difference was observed in the MnSOD allelotype distribution among esophageal squamous cell carcinomas and healthy controls (chi(2) = 4.

[Phase II clinical trial of concurrent chemoradiotherapy (cisplatin plus 5-fluorouracil) for esophageal cancer].

Background & Objective: Concurrent chemoradiotherapy is a standard treatment for local advanced esophageal cancer in overseas countries; however, the treatment outcomes are various in China. This study was to evaluate the efficacy of concurrent chemoradiotherapy with cisplatin plus 5-fluorouracil (PF) regimen on esophageal cancer, and observe the adverse events.

Methods: Forty-four patients with esophageal squamous cell carcinoma (ESCC) were randomized into two groups.

Phase I trial of escalating-dose cisplatin with 5-fluorouracil and concurrent radiotherapy in Chinese patients with esophageal cancer.

We defined the maximum-tolerated dose (MTD) of chemoradiotherapy (cisplatin (CDDP) with 5-fluorouracil (5-FU) and concurrent chemoradiotherapy) for Chinese patients with esophageal cancer. Twenty-one previously untreated patients with primary esophageal cancer were entered into this study. Escalating doses of CDDP with 5-FU were administered in a modified Fibonacci sequence, with concurrent conventional fractionation radiotherapy (CFR) of 60 Gy or 50 Gy.

Comparison of efficacy of regional and extensive clinical target volumes in postoperative radiotherapy for esophageal squamous cell carcinoma.

Purpose: To compare and analyze the effect of different clinical target volumes (CTVs) on survival rate after postoperative radiotherapy (RT) for esophageal squamous cell carcinoma (SCC).

Methods And Materials: We studied 102 patients who underwent postoperative RT after radical resection for esophageal SCC (T3/4 or N1). The radiation dose was > or =50 Gy.

Late course accelerated hyperfractionation radiotherapy concomitant with cisplatin in patients with esophageal carcinoma.

The purpose of this study was to examine whether combined cisplatin and late course accelerated fractionation radiotherapy (LCAH) (the combined group) can confer a better outcome over LCAH alone in treating esophageal carcinoma. Eighty-one eligible patients were randomly entered into two groups: the LCAH alone group, and the combined group. There was a better outcome in the combined group compared to the LCAH group, but the difference was not significant.
