This document is based on consensus among the experts and best available evidence pertaining to the Indian population and is meant for practice in India. Evaluation of a patient with newly diagnosed colorectal cancer (CRC) should include essential tests: A complete colonoscopy with biopsy, imaging (for colon cancer: Contrast-enhanced computed tomography (CECT) scan of the chest, abdomen and pelvis and for rectal cancer: Magnetic resonance imaging (MRI) of the pelvis, or an endoscopic ultrasound (EUS), with a chest and abdomen CECT), complete blood counts, liver and kidney function tests, carcinoembryonic antigen (CEA) and carbohydrate antigen 19.9 (CA19.9). For patients with localized colon cancer, resection is the treatment of choice, with consideration given to adjuvant chemotherapy for the patient with stage III and high-risk Stage II cancers. In patients with early rectal cancer (T1/T2, N0) surgery is the treatment of choice. Patients with locally advanced rectal cancer (T3/T4, N1, circumferential resection margin (CRM) threatened or involved) benefit from neoadjuvant therapy. Short course radiotherapy can be given if the CRM is not threatened. Others should undergo long course chemoradiotherapy. Adjuvant therapy is given to all patients receiving neoadjuvant therapy. Patients with potentially resectable metastatic liver limited disease should undergo synchronous or staged metastatectomy, along with neoadjuvant and adjuvant chemotherapy. Nonresectable metastatic disease must be assessed for chemotherapy versus best supportive care on an individual basis. Clinical examination and serum tumor markers are recommended at each followup visit, with imaging only done when either is abnormal or rising. Colonoscopic surveillance is also recommended for these patients. Source

B-cell lymphoma 2 (BCL2) and BCL2-associated X protein (BAX) proteins are anti-apoptotic and pro-apoptotic determinants of mitochondrial-mediated apoptosis, and their relative expression determines the cell fate. The promoter polymorphisms in these genes were shown to alter the protein function or expression and exert an impact on apoptosis regulation. Deregulation in the expression of any of these genes leads to disruption of cellular homeostasis and malignant transformation. The present study was aimed to determine the association of BCL2-938C>A and BAX-248G>A promoter polymorphisms with origin and progression of acute myeloid leukemia (AML). We also have performed combined genotype analysis to evaluate the cumulative effect of risk genotypes in the AML development. These polymorphisms were genotyped by polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) in 221 AML patients and 305 age- and sex-matched healthy controls. Our study revealed that BCL2-938CA (p = 0.018) and BAX-248GG (0.043) genotypes were significantly associated with increased risk for AML occurrence. BAX-248A allele had shown decreased risk for AML. The combined analysis had shown that BCL2-938CA+AA-BAX-248GG group had a 1.63-fold (95 % CI: 1.08–2.45, p = 0.02) increased risk for AML. None of the clinical variables had shown any significant association with both polymorphisms. With respect to complete remission (CR) rate, BAX-248GG genotype (p = 0.002) and G allele (p = 0.009) had conferred significant risk for complete remission failure. Although the log rank test was not significant, survival analysis had shown a trend where BCL2-938CA genotype, and BAX-248GG had reduced median disease-free survival (DFS) of 9 and 10 months, respectively. In conclusion, BCL2-938C>A and BAX-248G>A gene polymorphisms might contribute to the origin of AML. Moreover, influence of BAX-248GG genotype on CR and DFS rate suggests that the BAX-248G>A polymorphism can serve as marker for poor prognosis in AML. © 2015, International Society of Oncology and BioMarkers (ISOBM).

Hypoxia-inducible factor 1α (HIF-1α) is an important transcription factor that regulates different cellular responses to hypoxia. HIF-1α is rapidly degraded by von Hippel–Lindau (VHL) protein under normoxic conditions and stabilized under hypoxia. A common variant of HIF-1α (1772C>T) (rs 11549465) polymorphism, corresponding to an amino acid change from proline to serine at 582 position within the oxygen-dependent degradation domain, results in increased stability of the protein and altered transactivation of its target genes. The present study was aimed to find the association between HIF-1α (1772C>T) (rs 11549465) polymorphism and breast cancer development. For this purpose, 348 primary breast cancer patients and 320 healthy and age-matched controls were genotyped through PCR-RFLP method. The genotype frequencies were compared between patients and controls, and their influence on clinical characteristics of breast cancer patients was analyzed. Our study revealed a significant increase of TT genotype in breast cancer patients compared to controls (p = 0.038). Further, TT genotype and T allele were found to be associated with progesterone receptor (PR)-negative status (p < 0.09). None of the clinical variables revealed significant association with HIF-1α (1772C>T) (rs 11549465) polymorphism. © 2014, International Society of Oncology and BioMarkers (ISOBM). Source

Understanding spirituality during palliative care training is not easy. It slowly unravels itself when one starts caring for patients and meeting their caregivers. One such experience in the hospice has been described in this narrative. A person with advanced incurable cancer is initially in severe distress. Over time, he slowly comes to terms with the situation and eventually, a question from his illiterate wife - an insightful question about any last wish - brings out his desire to have certain religious rituals that were alien to his own religion. After his death, the family members concur with his last wish and also indulge in some religious rituals of their own choice. This story reaffirms that the essence of spirituality is the coexistence of harmony and humanity. © 2015 Taylor & Francis Group, LLC. Source

Objective: Altered differentiation is a common feature of haematopoietic malignancies with poor prognosis. CAAT/enhancer binding protein alpha (C/EBPα) is a key transcription factor that regulates myeloid differentiation. This study is aimed to know the prognostic value of CAAT/enhancer binding protein alpha expression and correlate its expression with response to imatinib therapy. Methods: We quantified the expression of C/EBPα gene in 126 chronic myeloid leukaemia samples (82 from newly diagnosed and 44 from imatinib-resistant patients) and 20 control samples. C/EBPα mRNA level was measured by real-time quantitative polymerase chain reaction using the ΔΔCT method. Results: C/EBPα expression level was significantly lower in the imatinib-resistant group than in the pretreatment and control group (P = 0.0398). Low CAAT/enhancer binding protein alpha levels in the imatinib-resistant group were significantly associated with advanced phase (P = 0.04), with more peripheral blasts (P = 0.0001), high BCR-ABL levels (P = 0.018) and T315I and P-loop mutations (P = 0.0002). In the pretreatment group, low expression showed association with high EUTOS risk score (P = 0.03) and possible partial cytogenetic response (P = 0.010). Conclusions: Our results suggest that lowexpression of CAAT/enhancer binding protein alpha might have a role in the response to imatinib and progression of disease in patients with chronic myeloid leukaemia. © The Author 2015.
