Nivolumab-associated Stevens-Johnson syndrome in a patient with lung cancer.

Nivolumab is a fully human immunoglobulin G4 immune checkpoint inhibitor antibody approved for use in the treatment of several malignancies such as lung cancer. Cutaneous reactions to checkpoint inhibitors are frequent, appearing in approximately 40% of patients. Although most of the reactions are well tolerated, these drugs can lead to severe cutaneous adverse reactions, but a quick recognition of the symptoms can significantly decrease their mortality.

Prospective Biomarker Study in Advanced RAS Wild-Type Colorectal Cancer: POSIBA Trial (GEMCAD 10-02).

Background: RAS testing is used to select patients with anti-epidermal growth factor receptor (EGFR) therapies sensitivity in metastatic colorectal cancer (mCRC). However, other biomarkers such as BRAF, PIK3CA/PTEN, and p-IGF-1R+/MMP7+ (double positive [DP] phenotype) have not been prospectively assessed to predict anti-EGFR resistance.

Materials And Methods: We designed a multicenter prospective trial (NCT01276379) to evaluate whether the biomarkers BRAF mutation, PIK3CA mutation/PTEN loss, and DP phenotype can improve the prediction for 12-months progression-free survival (PFS) over the use of clinical variables exclusively in patients with RAS wild-type (WT) mCRC treated with standard chemotherapy plus biweekly cetuximab as first-line therapy.

HIF pathway and c-Myc as biomarkers for response to sunitinib in metastatic clear-cell renal cell carcinoma.

Background: Clear-cell renal cell carcinoma (ccRCC) is a heterogeneous disease with a different clinical behavior and response to targeted therapies. Differences in hypoxia-inducible factor (HIF) expression have been used to classify von Hippel-Lindau gene (VHL)-deficient ccRCC tumors. c-Myc may be driving proliferation in HIF-2α-expressing tumors in a growth factor-independent manner.

Biochemical markers of bone turnover and clinical outcome in patients with renal cell and bladder carcinoma with bone metastases following treatment with zoledronic acid: The TUGAMO study.

Background: Levels of bone turnover markers (BTM) might be correlated with outcome in terms of skeletal-related events (SRE), disease progression, and death in patients with bladder cancer (BC) and renal cell carcinoma (RCC) with bone metastases (BM). We try to evaluate this possible correlation in patients who receive treatment with zoledronic acid (ZOL).

Methods: This observational, prospective, and multicenter study analysed BTM and clinical outcome in these patients.

Usefulness of bone turnover markers as predictors of mortality risk, disease progression and skeletal-related events appearance in patients with prostate cancer with bone metastases following treatment with zoledronic acid: TUGAMO study.

Background: Owing to the limited validity of clinical data on the treatment of prostate cancer (PCa) and bone metastases, biochemical markers are a promising tool for predicting survival, disease progression and skeletal-related events (SREs) in these patients. The aim of this study was to evaluate the predictive capacity of biochemical markers of bone turnover for mortality risk, disease progression and SREs in patients with PCa and bone metastases undergoing treatment with zoledronic acid (ZA).

Methods: This was an observational, prospective and multicenter study in which ninety-eight patients were included.

Skull metastasis from rectal gastrointestinal stromal tumours.

Gastrointestinal stromal tumours (GIST) are the most common mesenchymal neoplasm of the gastrointestinal tract. Rectum localisation is infrequent for these neoplasms, accounting for about 5% of all cases. Distant metastases of GIST are also rare.

Serum markers and prognosis in locally advanced breast cancer.

Background: Locally advanced breast cancer (LABC) represents a heterogeneous subgroup of breast cancer with an often dismal outcome. Identifying prognostic factors has acquired great significance for the selection of optimal treatment in individual patients.

Methods: Between January 1993 and December 1997, 103 patients were treated in our institution with multimodality treatment consisting of neoadjuvant chemotherapy followed by surgery, adjuvant chemotherapy and radiotherapy; tamoxifen was added in hormone receptor-positive cases.

Neoadjuvant cisplatin and etoposide, with or without tamoxifen, prior to radiotherapy in high-grade gliomas: a single-center experience.

Neoadjuvant chemotherapy (CT), prior to radical radiotherapy (RT), in the treatment of high-grade gliomas may offer several advantages over standard adjuvant CT. The addition of tamoxifen, which can circumvent P-glycoprotein (P-gp)-mediated chemo-resistance, also merits attention. We have evaluated the neoadjuvant regimen of cisplatin and etoposide after surgery of grade III-IV gliomas and prior to radical RT, with regard to response rates (RRs), overall survival (OS) and time to progression (TTP).

Lethal toxicity after 5-fluorouracil chemotherapy and its possible relationship to dihydropyrimidine dehydrogenase deficiency: a case report and review of the literature.

5-fluorouracil (5-FU) is a chemotherapeutic agent widely used in the treatment of solid malignancies, especially in colorectal cancer. A characteristic note seen with its use is the considerable interindividual variation in the incidence and severity of the toxicities seen among patients. We report the case of a 55-year old woman who presented with severe, lethal toxicity to standard doses of 5-fluorouracil (5-FU) and folinic acid.

Hepatic resection in breast cancer metastases: should it be considered standard treatment?

A 34-year-old woman was diagnosed in October 1994 with a stage I breast cancer and treated with conservative surgery, locoregional radiotherapy and adjuvant chemotherapy. Nonetheless, 47 months after the initial diagnosis, an isolated liver metastasis was diagnosed in segments VII and VIII. A subsegmentectomy was performed, and chemotherapy with doxorubicin and paclitaxel was given for five cycles.

Central nervous system metastases of a pulmonary epitheloid haemangioendothelioma.

The case of a 55-yr-old male with a right pleural effusion and multiple bilateral nodules is reported. A diagnostic thoracothomy was necessary to obtain a definitive histological diagnosis. During the postoperative course, the subject's neurological condition deteriorated and multiple cerebral mass lesions were discovered.

Analysis of clinical prognostic factors for survival and time to progression in patients with metastatic colorectal cancer treated with 5-fluorouracil-based chemotherapy.

Colorectal cancer (CRC) is one of the most common malignant tumors in adults. Twenty-five percent of patients are not amenable to surgical resection because they have locally advanced or metastatic disease. For these patients, median survival time is between 4 and 13 months, and chemotherapy is used mainly with palliative intent.
