Objectives: The resection status is one of the most important prognostic factors for patients with head and neck squamous cell carcinoma (HNSCC) concerning overall survival (OS) and recurrence free interval (RFI). To assess whether therapy concepts changed depending on different resection margins and extracapsular extension, OS and RFI data were set into clinical context. Methods: All HNSCC patients who underwent head and neck surgery with/without adjuvant therapy (n=534) were selected over a ten-year period (2001-2011)...

The role of acetylsalicylic acid (aspirin) as a chemo-preventive and adjuvant therapeutic agent for cancers is generating attention. Mounting evidence indicates that aspirin reduces the incidence and mortality of certain obesity-related cancers, particularly colorectal cancer. In endometrial cancer, previous studies examining the effect of aspirin remain inconsistent as to the reduction in the risk of endometrial cancer. While some evidence indicates protective effects in obese women, other studies have showed a potential deleterious effect of these medications on endometrial cancer outcomes...

Lower-extremities sarcoma patients, with bone tumor and soft-tissue sarcoma, are a unique population at high risk of physical dysfunction and chronic heart diseases. Thus, providing an adequate physical activity (PA) program constitutes a primary part of the adjuvant treatment, aiming to improve patients' quality of life. The main goal of this paper is to offer clear suggestions for clinicians regarding PA around the time between diagnosis and offered treatments. These preliminary recommendations reflect our interpretation of the clinical and preclinical data published on this topic, after a systematic search on the PubMed database...

Survival of all non-small cell lung cancer (NSCLC) patients is disappointing, with a 5-year survival of 18%. Staging NSCLC patients is crucial because it determines the choice of treatment and prognosis. Clinical staging is a complex process that comes with many challenges and with low accuracy between the clinical and pathological stage. Treatment modalities for stage I-III NSCLC consist of surgical resection, radiotherapy and chemotherapy. This review describes the current evidence on staging and the implications on adjuvant chemotherapy...

Hypopharynx cancer has the worst prognosis of all head and neck squamous cell cancers. Since the 1990s, a treatment shift has appeared from a total laryngectomy towards organ preservation therapies. Large randomized trials evaluating treatment strategies for hypopharynx cancer, however, remain scarce, and frequently this malignancy is evaluated together with larynx cancer. Therefore, our aim was to determine trends in incidence, treatment and survival of hypopharynx cancer. We performed a population-based cohort study including all patients diagnosed with T1-T4 hypopharynx cancer between 1991 and 2010 in the Netherlands...

BACKGROUND: The prognosis of stage IV gastric cancer (GC) still remains unfavorable. Multidisciplinary approaches should therefore be considered to improve the survival of patients with stage IV GC. We report here a case of primary GC with potentially unresectable metastasis, successfully treated by a multidisciplinary approach including chemotherapy, immunotherapy, and surgery. CASE PRESENTATION: A 74-year-old man presented with multiple left neck masses. Abdominal computed tomography showed a thickened gastric wall and multiple lymphadenopathies including left supraclavicular lymph node...

Cancer stem cells (CSCs) have been identified to exert tumor-initiating ability, resulting in the recurrence, metastasis and chemoresistance of oral squamous cell carcinomas. In the present study, we showed that GMI, an immunomodulatory protein from Ganoderma microsporum, induc ed a cytotoxic effect in oral carcinomas stem cells (OCSCs). Treatment of GMI dose-dependently inhibited the expression of CSC markers, including ALDH1 activity and CD44 positivity. Moreover, GMI suppressed the self-renewal property, colony formation, migration, and invasion abilities as well as potentiated chemo-sensitivity in OCSCs...

Bladder cancer is nowadays a common tumor. Non-muscle invasive bladder cancer (NMIBC) has still chances of recurrence and progression in spite of surgery and adjuvant treatments. New therapies are being developed to reduce these percentages with less adverse effects - Apaziquone (EO9) is an example. Areas covered: A literature search has been performed using Pubmed, UpToDate and Google verified information (mainly from Food and Drug Administration and Spectrum Pharmaceutics websites). We have included data from the most representative clinical trials and reviews published...

Small invasive breast cancers (cancers with maximum diameter <1cm, T1a,b) become more prevalent form of breast cancer as a result of the introduction of breast cancer mammographic screening programs. Although associated with an excellent prognosis, T1a,b breast cancers are heterogeneous group of tumors with prognostically unfavorable subset of cases, primarily those with axillary lymph node metastases. To determine if the HER2 overexpression is associated with the prognostically unfavorable traditional clinicopathological features in this group of breast cancers, clinicopathological features (age, tumor size, histological type, histological grade, nodal status, hormone receptor status, proliferation index, lymphovascular invasion, ploidy) of 38 HER2 positive T1a,b cancers were compared with those of the control group consisting of 315 HER2 negative T1a,b cancers...

Ovarian neoplasms are a heterogeneous group of tumors with varying incidence in the general population. The most common are the surface epithelial tumors which include transitional cell tumors. Transitional cell tumors include both transitional cell carcinoma and Brenner tumor. The vast majority of Brenner tumors are benign, often incidental findings; however, malignant Brenner tumors (MBT) do occasionally occur. MBT present similarly to other ovarian neoplasms with abdominal pain and bulk symptoms. On imaging, these tumors demonstrate nonspecific findings...

BACKGROUND: Chordomas are very rare tumors of the skull base and the sacrum. They show infiltrating and destructive growth and are known to be chemo- and radio-resistant. After surgical resection, the recurrence rate is high and overall survival limited. As current adjuvant treatments are ineffective, new treatment concepts are urgently needed. 5-aminolevulinic acid-based photodynamic therapy (5-ALA based PDT) showed promising results for malignant gliomas. However, it is unknown so far, whether chordomas accumulate protoporphyrin IX (PPIX) after application of 5-ALA and whether they are sensitive to subsequent 5-ALA based PDT...

NF-κB essential modulator (NEMO) binds and regulates IκB kinase (IKK) and is required for NF-κB activation. The NEMO-binding domain peptide (NBDP) of IKK was found to inhibit NF-κB activation and promote apoptosis in cancer cells. Studies have shown that constitutive NF-κB activation, one of the signature molecular alterations in pancreatic ductal adenocarcinoma (PDAC), is a potential therapeutic target. However, preclinical and therapeutic evidence that supports direct targeting of IKK activation in therapy is lacking...

BACKGROUND: Tumour response to neo-adjuvant radiotherapy for rectal cancer varies significantly between patients, as classified by Tumour Regression Grade (TRG 0-3), with 0 equating to pathological complete response (pCR) and 3 denoting minimal/no response. pCR is associated with significantly better local recurrence rates and survival, but is achieved in only 20-30% of patients. The literature contains limited data reporting factors predictive of tumour response and corresponding outcomes according to degree of regression...

Colon cancer is the third most frequent cancer and the fourth most common cause of cancer-related mortality worldwide and the standard therapy is surgical resection plus adjuvant chemotherapy. Photodynamic therapy (PDT) has been proposed as an adjuvant therapy because it can prevent the tumor recurrence after surgical excision in colon cancer patients. Hypoxia is a common feature in solid tumors and leads to chemo/radioresistance. Recently, it has been shown that in response to hypoxia, cells can induce HIF-1α-mediated autophagy to survive in this hostile microenvironment...

Breast cancer is one of the leading reasons for the morbidity and mortality of cancer related death globally. The modern therapies are basically the combination of the breast-preserving surgeries or ablation with or without node biopsy or destroying the carcinoma cells adjuvant with chemotherapy, radiotherapy, hormonal or biological therapies depending upon the nature of the receptor of the cancerous cells, nature of the lymph node, as well as the tendency of the recurrence. For decade's carcinoma management suffered by the limitation of imagining, targeting and penetrability problem associated with management and cure of this deadly disease leads to unwanted chemo-toxicity and side effects...

BACKGROUND: Kidney transplantation (KT) is the treatment option for patients with end stage renal disease (ESRD) to prolong survival and improve quality of life. Although the use of potent immunosuppressive agents increases graft survival in kidney transplantation recipients (KTRs), it may lead to the development of malignancy, including transitional cell carcinoma (TCC). TCC developing in the pelvis of graft kidney is very rare in KTRs. CASE PRESENTATION: A 40-year-old male visited hospital with complaints of nausea, vomiting and gross hematuria...

BACKGROUND: Complete resection for stage II thymic tumors can be easily accomplished even if the capsula and adjacent mediastinal tissue are macroscopically involved; however, also at this stage, recurrence may occur, particularly for B2, B3 and thymic carcinoma. The criteria for the administration of adjuvant therapy remain controversial and it is unclear whether patients at this stage may benefit from it. We reviewed a series of patients at this stage receiving adjuvant chemo-radiotherapy (chemo-RT) based on histology...
