Laryngeal cancer is the second most common cancer after the lip and oral cavity cancer ofhead and neck region1. Laryngeal malignancy is the seventh most common malignancy in males in India. Total number of new laryngeal cancer and death from laryngeal cancer have been estimated 12410 and 3760 respectively in 20192. As per last survey available the number of new cases diagnosed and total number of deaths from laryngeal malignancy were 25,460 and 17,560 respectively in 2012 in India3 . The incidence of cancer larynx is 1.26-8.18 per 100,000 populations in different regions of India. Carcinoma larynx constitutes40% of all Head and Neck cancers. Squamous cell carcinoma constitutes 95% of all malignancies of larynx. Glottis being the most common subsite followed by supraglottis and the least common site is the subglottis. There is an increasing incidence rate of this malignancy among middle aged and elderly men and women throughout the world. Expression of Biomarkers at different stages of laryngeal cancers and their impact on survival can play a crucial role in future management of laryngeal malignancies. In spite of having different modalities of treatments like surgery, radiotherapy, chemoradiation, the prognosis of laryngeal malignancies is still poor. The most common adverse factor for laryngeal cancer has been found lymph node metastasis. The process of progression of LSCC is complex and difficult to know it completely. Despite multi-modality therapeutic advances in recent decades, improvements in overall survival and disease free survival is very less. In this study we emphasized the role of expression of biomarkers vimentin and metastasis associated 1(MTA1) protein in different stages of laryngeal cancer and their impacts on survival.

Breast cancer is the most common malignancy in women. It is an immensely heterogeneous disease, characterised by a broad variety of clinical development. The research in recent years has focused on finding new markers of prognosis. This study investigates the role of expression of the bcl-2 protein in breast cancer. We analysed bcl-2 expression in 57 women with primary breast carcinoma who were treated with neoadjuvant (primary) chemotherapy, followed by a surgical procedure. The bcl-2 expression was correlated with other clinicopathological characteristics of the tumour – histological grade, stage, expression of hormonal receptors, proliferation rate, and with the survival of the patients. No significant association of bcl-2 expression with either overall survival or disease free survival was found.

Common Malignancy

Breast cancer is the most common malignancy in females globally. Various factors are responsible for its development which include both genetic and hormonal causes. An important discovery is the role of the PD-1/PD-L1 axis in the development of cancers. The PD-1-/PD-L1 pathway plays a part in allowing tumour cells escape from the hosts immune response and hence permits the proliferation of tumour cells. PD-L1 expression has been observed in various breast cancers at distinct levels such as in tissues and in blood. Different methods have been utilized for its detection including immunohistochemistry, RNA sequencing and ELISA, amongst others. The results have been conflicting regarding the expression of PD-L1 and the prognosis of breast cancer based on parameters such as overall survival and disease free survival. Different immunotherapies have also emerged as a new modality to treat breast cancer. This review intends to explore the prognostic significance of PD-L1 expression in breast cancers.

The introduction of aromatase inhibitors (AI) has provided more options for adjuvant treatment of postmenopausal women; they are associated with improved disease-free survival, but less commonly with improvements in overall survival. Current evidence suggests that women at high risk of recurrence, especially those with node-positive disease, should receive an AI for 2 years as part of their treatment, but routine prescription of AIs to postmenopausal patients with low-risk disease is not appropriate. Not only the expected benefits but also the specific toxicity of the prescribed hormone therapy, and its cost, should be considered when selecting treatment.

AbstractTotal laryngectomy for advanced carcinoma of the larynx is effective but functionally disabling. In an effort at laryngeal preservation, 33 patients of stage III/IV carcinoma larynx were treated between 1987 and 1991 with induction chemotherapy followed by definitive radiation. Two chemotherapy protocols were administered. Group I patients received one to three cycles of cisplatin 100 mg/m2 (day 1), bleomycin 15 U/m2 (day 1), and 5-fluorouracil 1000 mg/m2/day (day 2 to 5) at three weekly intervals. This was then followed by radiotherapy. Group II received one to six weekly injections of single agent methotrexate 50 mg/m2 with or without leucocovorin rescue followed by radiotherapy. Any recurrence was salvaged by surgery.Midway through the study, Group II protocol was discontinued as the initial results were not comparable with Group I or standard treatment. The Group I protocol, however, yielded an initial locoregional control rate of 83.3 per cent With the addition of surgical salvage the locoregional control rate was 94.4 per cent and the control rate with laryngeal preservation was 88.8 per cent. The Kaplan-Meier probability of two years and five years disease-free survival was 81.9 per cent and 61.4 per cent respectively. For disease-free survival with laryngeal preservation the corresponding figures for two years and five years were 58.3 per cent and 41.7 per cent.The control group of 51 patients treated with radical surgery followed by radiotherapy yielded survival figures at two years and five years of 64.3 per cent and 57.2 per cent. The difference in the survival of Group I and the control group was not statistically significant (p value = 0.280). These initial results indicate that for stage III and for surgically resectable stage IV laryngeal carcinomas, a protocol of induction combination chemotherapy consisting of cisplatin, bleomycin and 5-fluorouracil followed by radiotherapy and combined with surgical salvage whenever required, can lead to comparable cure rates. In addition, a large proportion of patients are spared the morbidity of a total laryngectomy.

Background/Aims: Several recent studies have demonstrated that Stathmin 1expression may be closely associated with prognosis in patients with various types of cancers. In the present study, we conducted a meta-analysis of all available studies in the English literature to assess the prognostic value of Stathmin 1expression in patients with solid cancers. Methods: The online databases PubMed, Embase, and Web of Science were searched for literature regarding Stathmin 1 and its association with patient outcomes associated with solid cancers. Results: A total of 23 articles including 26 studies that contained 5 335 patients were retrieved and analyzed. Our results indicated that high Stathmin 1 expression yielded a worse overall survival (OS) (hazard ratio [HR] = 2.17, 95% confidence interval [CI]: 1.81–2.60), disease-free survival (DFS) (HR = 2.46, 95% CI: 2.00–3.02), disease-specific survival (DSS) (HR = 1.98, 95% CI: 1.58– 2.47) and progression-free survival (PFS)/recurrence-free survival (RFS) (HR = 2.09, 95% CI: 1.51–2.89). Furthermore, the association of high Stathmin 1 expression with poor survival was significant even for sub-group analyses of different tumor types, ethnicities, methods used to calculate HRs, detected methods, and analysis types. Conclusion: In summary, this meta-analysis determined that high Stathmin 1 expression is associated with poor prognosis in patients with solid cancers and expression of this protein could be a clinically useful prognostic biomarker.

AbstractObjective:To evaluate the clinical and histopathological factors affecting the prognosis of patients with squamous cell locoregional advanced laryngeal cancer.Methods:A retrospective chart review was conducted of 121 patients with locoregional advanced laryngeal cancer, primarily treated with surgery from 2007 to 2011. Disease-free survival and overall survival rates were analysed as oncological outcomes. Prognostic variables, namely gender, pharyngeal invasion, pathological assessment of tumour and nodal stage, adjuvant therapy, margin status, nodal extracapsular extension, tumour differentiation, lymphovascular and perineural invasion, and predominant growth pattern, were also analysed.Results:One-year and three-year disease-free survival rates were 81.3 per cent and 63.5 per cent, respectively. One-year and three-year overall survival rates were 88.3 per cent and 61.4 per cent, respectively. Multivariate analysis showed that nodal extracapsular extension (p < 0.05) and an infiltrative growth pattern (p < 0.05) were associated with disease progression. Nodal extracapsular extension (p < 0.05) was associated with higher mortality.Conclusion:Nodal extracapsular extension and an infiltrative growth pattern were the main prognostic factors in locoregional advanced laryngeal cancer. The presence of pharyngeal invasion, pathologically confirmed node-positive stage 2–3 disease, close or microscopic positive margins, and lymphovascular and perineural invasion have a negative impact on prognosis.

Gata3 Protein

Several mutations act as driver mutations in breast cancer, including GATA3 mutations. Reports of the relation between GATA3 mutations and breast cancer prognosis remain conflicting. Also, the role of GATA3 germline mutations is not well studied. We hypothesize that different mutation types could have different effects. Also, this study aims to assess effect of GATA3 mutations on GATA3 protein function as a transcription factor, and target pathways affected. DNA from de novo breast cancer female patients was sequenced to detect exon 6 GATA3 mutation. Sequence analysis was performed along with clinical and prognostic parameters and disease-free survival. Public datasets were analyzed for differentially expressed genes and pathways with mutant GATA3 patients. Mutations in GATA3 exon 6 were detected in 56.1% of patients (including 2 novel, Lys368fs, Pro354Lys). Intronic mutations were significantly higher in long disease-free survival group, while frameshift mutations were significantly higher in short DFS group. Patients with tumor size ≥20 had significantly higher protein coding and lower intronic mutations compared to patients with tumor size <20 mm. Differential expression and pathway analysis showed that mutant GATA3 had lost its negative regulatory effect on several pathways such as: signaling by interleukins, regulation of TP53 expression, and RUNX3 regulated CDKN1A transcription pathway. PIK3CA, SKP1, FBP1, SMAD3, ANXA9 and CLSTN2 were positively correlated to wild-type GATA3 expression, but not mutant GATA3. Intronic germline mutations of GATA3 could be related to better prognosis, while protein coding GATA3 germline mutations could be related to unfavorable prognosis. GATA3 mutations lead to dysregulation of pathways related to immunity, breast cancer development, and metabolism. Impact statement GATA3 mutations are known to play an important role in breast cancer progression. The exact role and mechanisms of these mutations remain controversial as some studies suggest a relation to breast tumor growth, while others suggest a relation to longer survival. GATA3 germline mutations are not well studied in breast cancer. In this study, it was hypothesized that different types of GATA3 mutations could contribute to the breast cancer progression in different ways. GATA3 exon 6, which is important for GATA3 protein functions, was reported to have hotspots, and hence it was selected for study. Intronic GATA3 germline mutations were found to be related to favorable prognosis, while protein coding mutations were found to be related to unfavorable prognosis. Bioinformatics study of large publically available datasets showed that GATA3 mutations lead to dysregulation of pathways related to T-cells activation, inflammation, and breast cancer development.

Actuarial Method

The authors report on 283 primary, non-metastatic, breast cancer cases consecutively referred after surgery and followed-up from a minimum of 10 months to a maximum of 3.5 years. All cases were studied according to the presence of estrogen receptors (ER). ER presence was correlated with age and menstrual status, with ER+ cases more frequent in older patients. No correlation was found between ER and nodal status. Prognosis was evaluated in terms of disease-free survival at 2 years (actuarial method). No correlation between ER and survival was evident for N– cases, whereas a better prognosis was recorded for ER+N+ patients compared to ER-N+, although the difference was not statistically significant. The observed results are compared with recent literature data and agree with other recent reports, which did not confirm the previously undiscussed statement regarding the prognostic role of ER determination. According to these studies and to the present study, the prognostic role of ER determination seems at least questionable and particularly the postoperative adjuvant treatment of ER-N– cases should be reconsidered.
