Gemcitabine pulmonary toxicity

Gemcitabine is a cytotoxic drug commonly used in the treatment of several types of cancer. While gemcitabine is generally considered safe and effective, it can cause some side effects, including pulmonary toxicity. Interstitial lung disease is a rare but potentially serious event. We report a case of a 63-year-old patient with advanced pancreatic adenocarcinoma. She received Gemcitabine 1000 mg/m2 on day 1, and day 8, and presented on day 15 of the first cycle with respiratory distress rapidly aggravating...

Gemcitabine is a nucleoside analogue of deoxycytidine and has been reported to be a broad-spectrum antiviral agent against both DNA and RNA viruses. Screening of a nucleos(t)ide analogue-focused library identified gemcitabine and its derivatives (compounds 1 , 2a , and 3a ) blocking influenza virus infection. To improve their antiviral selectivity by reducing cytotoxicity, 14 additional derivatives were synthesized in which the pyridine rings of 2a and 3a were chemically modified. Structure-and-activity and structure-and-toxicity relationship studies demonstrated that compounds 2e and 2h were most potent against influenza A and B viruses but minimally cytotoxic...

BACKGROUND: Extra-pulmonary neuroendocrine carcinomas (EP-NECs) are rare, accounting for ~1/100,000 of NECs, aggressive neoplasms and poor prognosis. Sometimes, a non-neuroendocrine component is also accompanying these EP-NECs. Curative surgery is suggested for early stage patients while system chemotherapy and locoregional radiotherapy are considered for advanced inoperable disease. Nonetheless, there was lack of standard second-line treatment strategy. Herein, we report a case of NEC involving a large cell neuroendocrine carcinoma (LCNEC) and adenocarcinoma of the gallbladder treated with a surufatinib-containing regimen in the second-line treatment setting and establish the efficacy of this regimen in the treatment of EP-NECs...

Carboplatin is a chemotherapy agent widely used in veterinary oncology to treat various types of tumors including carcinomas. Carboplatin has previously been used in combination with 5-Fluoro uracil (5-FU) or gemcitabine for the treatment of various carcinomas. Bleomycin is a chemotherapy drug commonly used in humans, but its use has been uncommonly reported in dogs. The combination of carboplatin and bleomycin chemotherapy treatment has never been reported in dogs. Dogs diagnosed with carcinoma and treated with a combination of carboplatin and bleomycin, at a single veterinary referral center, were retrospectively evaluated...

INTRODUCTION: The standard of care (SoC) for unresectable stage III non-small-cell lung cancer (NSCLC) is durvalumab maintenance therapy after concurrent chemoradiation in patients with PD-L1 > 1%. However, the concurrent approach is only amenable for about one-third of patients due to co-morbidities. Although sequential regimens are usually not regarded as curative, these schedules applied in a dose-escalated manner may be similarly radical as SoC. As combining high-dose radiation and durvalumab remains a question of debate this retrospective bi-center study aims to evaluate pulmonary toxicity after high-dose chemoradiotherapy beyond 70 Gy compared to SoC...

BACKGROUND: CEND-1 is a novel cyclic peptide that targets αV integrins and neuropilin-1 and enhances tumour delivery of co-administered anticancer drugs. We investigated the safety, tolerability, and biological activity of CEND-1 in patients with metastatic pancreatic ductal adenocarcinoma in combination with nab-paclitaxel and gemcitabine. METHODS: This open-label, multicentre, phase 1 study, conducted at three hospitals in Australia, enrolled participants aged 18 years or older with histologically confirmed metastatic pancreatic ductal adenocarcinoma who had one or more lesions measurable on MRI or CT, an Eastern Cooperative Oncology Group performance status score of 0 or 1, and a life expectancy of at least 3 months...

BACKGROUND: Data are currently insufficient to support the use of adjuvant chemotherapy (ACT) after surgical resection for stage II or III non-small cell lung cancer (NSCLC) in patients aged ≥ 75 years. In this study we evaluated efficacy and safety profile of ACT in this population. METHODS: We retrospectively evaluated 140 patients ≥ 75 years who underwent curative surgical resection for stage II-III NSCLC from 2010 to 2018 with an indication to ACT according to current guidelines...

PURPOSE: VEGF receptor-2 (VEGFR-2)-mediated angiogenesis contributes to pathogenesis of biliary tract cancers (BTC). We investigated ramucirumab, a monoclonal antibody targeting VEGFR-2 for treatment of advanced, chemo-refractory BTC. EXPERIMENTAL DESIGN: This is a phase II, single-arm trial for advanced, unresectable, pre-treated BTC patients with ECOG 0/1, adequate liver, renal, and marrow functions. Ramucirumab was administered at 8 mg/kg, 2 weekly with restaging performed 8 weekly...

Background Pulmonary toxicity due to chemotherapeutic agents can occur with many established and new drugs. Strong clinical suspicion is important as the clinical presentation is usually with nonspecific symptoms like cough, dyspnea, fever, and pulmonary infiltrates. Timely discontinuation of the offending agent alone can improve the condition. Methods A prospective observational study on patients receiving chemotherapy at an 800-bedded tertiary care hospital was performed from 2014 to 2016. Consecutive patients on chemotherapy, presenting with nonresolving respiratory symptoms were evaluated with contrast-enhanced computerized tomography of chest, diffusion lung capacity for carbon monoxide (DLCO), fiberoptic bronchoscopy with lavage, and biopsy, after excluding all causes for pulmonary infections...

INTRODUCTION: The present systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs) aimed to compare the mortality rates related to adverse events (AEs) and discontinuation of treatment due to toxicity as well as all AEs of currently used chemotherapy regimens for first-line therapy of advanced or metastatic urothelial carcinoma of the bladder (UCB). MATERIAL AND METHODS: The MEDLINE and EMBASE databases were searched for articles published between January 2000 and June 2020 according to the Preferred Reporting Items for Systematic Review and Meta-analysis extension statement for NMA...

We describe a case of unusually persistent vasoplegia in the postoperative course of a patient recovering after elective right robotic nephroureterectomy with intravesical salvage gemcitabine. In the treatment of patients with intravesical adjuvant therapy, gemcitabine may precipitate persistent vasoplegia requiring further fluid resuscitative efforts, vasopressor support, and other supportive management. This potential adverse event should be considered when all common causes of persistent vasoplegia are ruled out, such as shock related to bleeding, infection, allergic reaction, or pulmonary embolic phenomenon...

BACKGROUND: Biliary tract cancers are aggressive, rare, gastrointestinal malignancies with a poor prognosis; approximately half of patients with these cancers survive for less than 1 year after diagnosis with advanced disease. We aimed to evaluate the efficacy and safety of ramucirumab or merestinib in addition to first-line cisplatin-gemcitabine in patients with locally advanced or metastatic biliary tract cancer. METHODS: We did a randomised, double-blind, phase 2 study at 81 hospitals across 18 countries...

BACKGROUND: Hodgkin lymphoma (HL) is lymphoid neoplasm usually affecting lymphatic system; it accounts 3.6% of cancers in Saudi Arabia. Modern treatment protocols had shown particular success rates in overall-survival (OS) and event-free-survival (EFS). In our study, we reviewed the medical records of 80 pediatric and young adolescent patients diagnosed HL from January 2006 to July 2020, treated at tertiary care hospital in Riyadh, Saudi Arabia. Demographic, clinical, and pathological data were explored...

Various chemotherapies are used to treat testicular cancer. The most common therapy regimens are BEP (cisplatin, etoposide, bleomycin), carboplatin mono (AUC 7), PEI (cisplatin, etoposide, ifosfamide), TIP (cisplatin, ifosfamide, paclitaxel) and GOP (gemcitabine, oxaliplatin, paclitaxel). This is accompanied by acute and late toxicities. These include general side effects such as anemia, neutropenia, nausea, vomiting, diarrhea, mucositis or paravasation as well as special toxicities like ototoxicity, nephrotoxicity, pulmonary toxicity, neurotoxicity or Raynaud's syndrome...

BACKGROUND: Pulmonary sarcomatoid cancer (PSC) is a very rare subtype of poorly differentiated non-small-lung-cancer (NSCLC) with very poor prognosis. To date, the optimal treatment for PSC has not been elucidated, and the efficacy of anlotinib in PSC has not been previously reported. CASE PRESENTATION: A 77-year-old male patient was admitted with cough, expectoration, and blood-stained sputum for one month. CT showed a soft mass in the inferior lobe of the right lung, which was diagnosed as spindle cell carcinoma (PSC) by histopathology...

Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are rare tumors composed of two different histological components, one of which is of a neuroendocrine origin. Given its suggested underdiagnosis and consequent low prevalence, no clear diagnostic and treatment guidelines are available, and treatment usually follows regimens similar to that of the most aggressive component. On the other hand, multiple primary tumors (MPTs) are also rare neoplastic entities that usually confer a challenge regarding treatment options, for a regimen that comprises both the primary and the synchronous/metachronous malignancy should be used...

BACKGROUND: Almost all patients with malignant mesothelioma eventually have disease progression after first-line therapy. Previous studies have investigated maintenance therapy, but none has shown a great effect. We aimed to assess the efficacy and safety of switch-maintenance gemcitabine in patients with malignant mesothelioma without disease progression after first-line chemotherapy. METHODS: We did a randomised, open-label, phase 2 trial in 18 hospitals in the Netherlands (NVALT19)...

BACKGROUND: Gemcitabine is a chemotherapy agent with relatively low toxicities, as a valid option for elderly patients with underlying diseases. Gemcitabine-induced pulmonary toxicities are rare and various, ranging from self-limited episodes of bronchospasm to fatal, progressive, severe, interstitial pneumonitis and respiratory failure. Intravesical gemcitabine instillations are commonly used to reduce recurrence or progression for non-muscle-invasive bladder cancer or urothelial cancer...

The regimen of oxaliplatin with 5-fluorouracil plus l-leucovorin (FOLFOX) has become one of the most commonly used first-line chemotherapy for patients with advanced colorectal cancer and it provides an increase in disease-free survival as well as an overall survival benefit. Although FOLFOX chemotherapy has helped to improve the clinical outcomes in these patients, the regimen is associated with some therapeutic issues or uncontrolled side effects. Gastrointestinal, neurosensory, and hematological toxicities have frequently been observed in patients treated with FOLFOX, and consequently, some palliative treatment has been established to combat such complications...

BACKGROUND: Second-line salvage therapy for patients with metastatic germ-cell cancer (GCC) after the first-line combination of VIP (etoposide, ifosfamide, cisplatin) therapy has not been established. This study evaluated the efficacy and tolerability of the TGP (paclitaxel, gemcitabine, cisplatin) combination chemotherapy as a second-line salvage therapy. PATIENTS AND METHODS: The medical records of 16 consecutive patients with metastatic GCC who had been treated with first-line VIP therapy followed by second-line TGP therapy between 2005 and 2019 were reviewed and statistically analyzed...
