A case report and mini literature review of thyroid metastasis from colorectal cancer: Challenges in the diagnosis and treatment of a rare clinical entity.

The incidence of thyroid metastases among patients suffering from primary colorectal cancer is rare. As these metastases are usually asymptomatic, they present as incidentalomas on follow-up imaging. Hereby, we present and discuss a case of metastatic sigmoid adenocarcinoma to the thyroid gland, diagnosed and treated at our institution.

Mediastinal and hilar sarcoid-like reaction in a patient treated with dabrafenib and trametinib for metastatic melanoma: A case report and review of the literature.

BRAF/MEK inhibitors are considered standard of care in the treatment of advanced BRAF-mutated malignant melanoma, and have been, in rare cases, associated with granulomatous reactions, mostly limited to skin lesions. The present study reported the case of a patient with metastatic melanoma developing a sarcoid-like reaction manifesting as asymptomatic mediastinal and right hilar lymphadenopathy while on antineoplastic therapy with dabrafenib and trametinib. To the best of our knowledge, this is the first reported case of isolated lymphadenopathy as a manifestation of drug-induced sarcoid-like reaction under dabrafenib and trametinib.

Association between homeobox protein transcript antisense intergenic ribonucleic acid genetic polymorphisms and cholangiocarcinoma.

Background: Cholangiocarcinoma (CCA) represents a rare but highly aggressive malignancy that is often challenging to diagnose, especially in early stages. The role of existing tumor biomarkers for CCA diagnosis, remains controversial due to their low sensitivity and specificity. Increasing evidence has implicated long non-coding ribonucleic acid polymorphisms with cancer susceptibility in a variety of tumor types.

Exosomal noncoding RNAs in cholangiocarcinoma: Laboratory noise or hope?

Currently, extracellular vesicles and particularly exosomes have gained a lot of research interest due to their unique roles in several biological processes. Noncoding RNAs (microRNAs, long noncoding RNAs and circular RNAs) represent a class of functional RNA with distinct regulatory roles in tumorigenesis and cancer progression. Cholangiocarcinoma is a rare but highly aggressive type of malignancy that is very challenging to diagnose, especially in early stages; surgical resection still represents the sole potentially curative treatment option.

MiR-218 and miR-100 polymorphisms as markers of irinotecan-based chemotherapy response in metastatic colorectal cancer.

Purpose: Colorectal cancer is the fourth cause of cancer-related death. Drug toxicity and resistance remain concerns of major importance. miR-100 and miR-218 are micro-RNAs that regulate cellular proliferation, differentiation and apoptosis acting as oncogenes and tumour suppressors; their functions and have been linked with toxicity development and drug resistance.

Fluoropyrimidine-induced toxicity and DPD deficiency.. A case report of early onset, lethal capecitabine-induced toxicity and mini review of the literature. Uridine triacetate: Efficacy and safety as an antidote. Is it accessible outside USA?

Fluoropyrimidine-based regimens are among the most commonly used chemotherapy combinations for the treatment of solid tumors. Several genetic polymorphisms that are implicated with fluoropyrimidine anabolism and catabolism have been associated with the development of life-threatening toxicities. Uridine triacetate is an FDA-approved antidote for 5-fluorouracil or capecitabine overdose and early-onset, life-threatening toxicity within 96 h of last chemotherapy dose.

An anatomic anal sphincter-saving procedure for rectal cancers located at anorectal junction.

Background: This study aims to present the feasibility of the open approach of hemilevator excision (HLE) as a promising alternative of the laparoscopic and/or robotic ones for the treatment of low rectal cancer extending to the ipsilateral puborectalis muscle.

Methods: A 60-year-old male patient with a high-grade differentiated rectal adenocarcinoma at the right side of the lower rectum invading puborectalis muscle. The proposed operation consists of a combination of extralevator abdomino-perineal excision (ELAPE), intersphicteric resection (ISR), and low anterior resection (LAR) since it resects the ipsilateral to tumor levator ani muscle (LAM) from its attachment at the internal obturator fascia and the deep part of ipsilateral external anal sphincter (EAS), while the distal part of dissection is completed in the intersphincteric space taking out the internal anal sphincter (IAS).

Long non-coding RNA polymorphisms and prediction of response to chemotherapy based on irinotecan in patients with metastatic colorectal cancer.

Background: Colorectal cancer is the fourth cause of cancer related death. Drug resistance and toxicity remain major clinical issues. HOTAIR and MALAT1 are long non-coding RNAS that affect cellular proliferation, apoptosis and drug resistance; their up-regulation has been linked with a poor prognosis.

AMALTHEA: Prospective, Single-Arm Study of the Hellenic Cooperative Oncology Group (HeCOG) Evaluating Efficacy and Safety of First-Line FOLFIRI + Aflibercept for 6 Months Followed by Aflibercept Maintenance in Patients With Metastatic Colorectal Cancer.

Background: The efficacy and safety of the FOLFIRI (leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin) regimen combined with aflibercept has not been studied in the first-line management of patients with metastatic colorectal cancer (mCRC).

Patients And Methods: In the context of a prospective single-arm trial (NCT02129257), patients with mCRC received standard doses of a maximum of 12 cycles of FOLFIRI combined with aflibercept (4 mg/kg body weight delivered intravenously) every 2 weeks, followed by aflibercept maintenance. Endpoints were 12-month progression-free survival rate, efficacy, and toxicity.

Anti-PD1/PDL1 induced psoriasis.

Background: Immune checkpoint inhibitors are novel agents approved for the treatment of late-stage malignancies. Despite its important clinical benefits, checkpoint inhibition is associated with a unique spectrum of side effects known as immune-related adverse events. Skin toxicities are the most frequent immune-related adverse events during anti-PD1 blockade therapies.

Lessons from the past: Long-term safety and survival outcomes of a prematurely terminated randomized controlled trial on prophylactic vs. hemoglobin-based administration of erythropoiesis-stimulating agents in patients with chemotherapy-induced anemia.

Prophylactic erythropoiesis-stimulating agent (ESA) administration for chemotherapy-induced anemia (CIA) is not supported by current guidelines. Long-term follow-up of patients WHO had been treated with ESA for CIA in the past may provide useful information. In 2002, we undertook a prospective, randomized phase III trial of prophylactic vs.

Gastrointestinal Stromal Tumors (GIST): A Prospective Analysis and an Update on Biomarkers and Current Treatment Concepts.

Gastrointestinal stromal tumors (GIST) are the most common sarcomas of the gastrointestinal tract, with transformation typically driven by activating mutations of cKIT and less commonly platelet-derived growth factor receptor alpha (PDGFRA). Successful targeting of tyrosine-protein kinase Kit with imatinib, a tyrosine kinase inhibitor, has had a major impact in the survival of patients with GIST in both the adjuvant and metastatic setting. A recent modification of treatment guidelines for patients with localized, high-risk GIST extended the adjuvant treatment duration from 1 year to 3 years.

Feasibility of Induction Docetaxel, Cisplatin, 5-Fluorouracil, Cetuximab (TPF-C) Followed by Concurrent Cetuximab Radiotherapy for Locally Advanced Head and Neck Squamous Cell Carcinoma.

Purpose: To report our experience with a sequential regimen of induction TPF-C followed by radioimmunotherapy with cetuximab in patients with locally advanced head and neck squamous cell carcinoma (HNSCC).

Patients And Methods: Toxicity and outcome was retrospectively analyzed in 22 patients receiving sequential therapy with induction TPF-C followed by radioimmunotherapy between October 2008 and December 2011. Outcome was estimated using Kaplan-Meier analyses.

Sequential treatment with sorafenib and sunitinib in metastatic renal cell carcinoma: clinical outcomes from a retrospective clinical study.

Sorafenib and sunitinib are inhibitors of receptor protein tyrosine kinases (TKIs) and are approved for the treatment of metastatic renal cell carcinoma (mRCC). Although the mTOR inhibitor everolimus is effective for the treatment of patients who have failed TKI therapy, it is important to consider all available treatment options before switching therapy mode of action. Herein, we report outcomes in patients with mRCC switched to sorafenib following disease progression on sunitinib treatment.

Current chemotherapeutic options for the treatment of advanced bladder cancer: a review.

Advanced bladder cancer is a disease with a high recurrence rate and metastatic capacity exhibiting a poor outcome. The pathologic stage and nodal involvement are independent prognostic factors for survival after cystectomy, and in locally advanced or metastatic disease, the performance status and the presence of visceral metastases have been correlated with treatment outcome. The regimen methotrexate-vinblastine-adriamycin-cisplatin (MVAC) has been the treatment of choice for decades and later the combination of cisplatin with gemcitabine became also the new standard of care, by demonstrating a more favorable toxicity profile.

Targeted treatment for metastatic renal cell carcinoma and immune regulation.

New targeted agents have become the mainstream of treatment in metastatic renal cell carcinoma (mRCC) and substituted the previous cytokine-based therapies. Vascular endothelial growth factor (VEGF) pathway is the principle target for drugs like sunitinib, sorafenib and bevacizumab. As VEGF is regulating dendritic cell (DC) function, inhibition of VEGF results in activation of DCs and a shift towards cellular (type 1) immunity, which is believed to favor cancer rejection.

Extramedullary (EMP) relapse in unusual locations in multiple myeloma: Is there an association with precedent thalidomide administration and a correlation of special biological features with treatment and outcome?

Extramedullary relapse constitutes an uncommon manifestation of multiple myeloma (MM), characterized by highly malignant histology, special biological features, resistance to treatment and poor outcome. Its incidence has been increased during the last years, probably due to the introduction of novel strategies in the management of MM, including intensified treatment and immunomodulatory drugs. Here we report nine cases of extramedullary relapse of MM, presented in unusual locations, seven of which had previously been treated with thalidomide-containing regimens (TCR).

Paraneoplastic pemphigus regression after thymoma resection.

Background: Among human neoplasms thymomas are associated with highest frequency with paraneoplastic autoimmune diseases.

Case Presentation: A case of a 42-year-old woman with paraneoplastic pemphigus as the first manifestation of thymoma is reported. Transsternal complete thymoma resection achieved pemphigus regression.

Erythropoiesis-stimulating agents are associated with reduced survival in patients with multiple myeloma.

The impact of erythropoiesis-stimulating agent (ESA) on cancer patients' survival has recently become a matter of extensive discussion. Studies in solid tumors demonstrated that ESA adversely affects survival. This issue has not been sufficiently studied in patients with multiple myeloma.
