Background: Paragangliomas and extra-adrenal pheochromocytomas are uncommon neuroendocrine tumors with ubiquitous distribution. Malignant paraganglioma is a relatively rare entity. We report the treatment and pathological characteristics of a patient with malignant paraganglioma, and summarize the latest advances in the treatment of malignant paraganglioma based on a literature review.

Article Synopsis
  • - The study aimed to assess whether adding high-dose vitamin C to the standard chemotherapy (FOLFOX ± bevacizumab) would improve outcomes for patients with metastatic colorectal cancer (mCRC).
  • - Results showed that there was no significant difference in progression-free survival (PFS), overall survival (OS), or response rates between the vitamin C group and the control group, although patients with RAS mutations did experience longer PFS with vitamin C.
  • - Overall, high-dose vitamin C did not provide a clear benefit over standard chemotherapy for mCRC, except potentially for patients with specific genetic mutations (RAS mutation).

Gastric cancer (GC) is the second most common cancer in China. The ToGA study showed that trastuzumab in combination with fluoropyrimidine plus cisplatin prolonged overall survival (OS) in patients with human epidermal growth factor receptor 2 (HER2)-positive advanced GC (AGC). However, some patients may not be able to receive this regimen.

Purpose: To evaluate the safety and clinical effectiveness of computed tomography (CT)-guided cryoablation for adrenal pheochromocytoma (AP).

Materials And Methods: From July 2015 to October 2018, we observed 8 patients that underwent CT-guided cryoablation for AP. The blood pressure and pulse before treatment did not exceed 150/90 mm Hg and 90 times/min, respectively.

To evaluate the feasibility, local control, and survival after computed tomography (CT)-guided cryoablation for adrenal metastases.This study included 31 consecutive patients with adrenal metastases who were treated by CT-guided cryoablation in our center from July 2011 to October 2017. The technical success rate, local progression rate, local progression-free survival (LPFS), systemic progression-free survival (SPFS), and overall survival were assessed.

Background: Circulating cell-free DNA (ccf-DNA) in plasma may contain both specific and non-specific of tumor markers. The concentration and integrity of ccf-DNA may be clinical useful for detecting and predicting cancer progression.

Methods: Plasma samples from 40 healthy controls and 73 patients with gastric cancers (two stage 0, 17 stage I, 11 stage II, 33 stage III, and 10 stage IV according to American Joint Committee on Cancer stage) were assessed respectively.

Previous studies have drawn attention to dendritic cell (DC) vaccines; particularly the application of the tumor-associated antigen-targeted DC vaccine. The present study analyzed DCs derived from a normal individual and pulsed the cells with heat shock protein 70 peptide (Hsp70) and/or hepatitis B virus x antigen (HBxAg), a hepatocellular carcinoma (HCC)-associated antigen. It was then investigated whether this method of vaccination induced strong therapeutic antitumor immunity.

Purpose: To report the results of a safety analysis from a phase II trial comparing administration of weekly paclitaxel plus S-1 (TS) versus paclitaxel plus 5-fluorouracil (5-FU)/calcium folinate (LV) (TLF) as first-line therapy for advanced gastric cancer.

Methods: Patients (n = 240) with previously untreated advanced gastric cancer were randomly assigned to receive either TS or TLF in a 28-day cycle for six cycles.

Results: The clinical features of both sets of patients were similar, with the exception of the incidence of prior chemotherapy (P>0·05).

Aim: S-1 is an oral anticancer fluoropyrimidine formulation consisting of tegafur, 5-chloro-2,4-dihydroxypyridine and potassium oxonate. The aim of this study was to evaluate the pharmacokinetics and bioequivalence of a newly developed generic formulation of S-1 in Chinese cancer patients in comparison with the branded reference formulation of S-1.

Methods: A single-dose, randomized-sequence, open-label, two-way self-crossover study was conducted in 30 Chinese cancer patients.

Objective: To evaluate the efficacy and safety of weekly paclitaxel combined with S-1 or fluorouracil in the first line treatment of advanced gastric carcinoma.

Methods: Two hundred and forty patients with untreated advanced gastric carcinoma were randomized into two arms, patients in the experimental arm were given paclitaxel and S-1, while those in the control arm received paclitaxel and fluorouracil. The regimen of experimental arm was paclitaxel 60 mg/m(2) by intravenous infusion, day 1, 8, 15; S-1 80 - 120 mg/day given by oral administration, day 1 - 14.

Background: Accumulating evidence demonstrates that the microenvironment of the host has an important effect on the chemoresistance of tumors. We also found that the formation of intrinsic multidrug resistance is related to environmental factors that are common with tumor growth of hepatocellular carcinoma. The aim of this study was to explore the molecular mechanisms by which multidrug resistance of hepatocellular carcinoma is induced by the microenvironment.

Objective: To analyze the efficacy and quality of life and safety for paclitaxel and carboplatin (TC) and TC combined with endostar in the treatment of advanced non-small cell lung cancer (NSCLC).

Methods: This is a prospective, multicenter, randomized, double-blind, placebo-controlled clinical study. A total of 126 cases of untreated advanced NSCLC were enrolled in this study.

Objective: To investigate the clinical safety and effects of auto-dendritic cells pulsed with HLA-A201-binding peptides prostate-specific antigen (PSA) , prostate-specific membrane antigen (PSMA) and prostatic acid phosphatase (PAP) in the treatment of hormone-refractory metastatic prostate cancer (HRPC).

Methods: Sixteen HRPC patients with positive HLA-A201 were enrolled and their monocytes isolated and induced into dendritic cells with the combination of rhGM-CSF and rhIL4. The patients were inoculated subcutaneously near the inguinal region with auto-DCs pulsed with peptides PSA (KLQCVDLHV) , PSMA (ALDVYNGL L) and PAP (LLHETDSAV) every 2 weeks for 4 times, and the immunological and clinical responses were examined within 1 -2 weeks after the final vaccination.
