Oncology Case Report - When Is the Appropriate Time to Integrate Palliative Care?

Many patients with advanced, non-curable cancer experience disease progression to a stage requiring symptomatic care alone. The integration of palliative care into oncology practice is therefore important, with many studies showing the benefits of early introduction of palliative care. In addition to symptom relief, palliative care can include psychological, social, and spiritual support. Although all oncologists provide basic palliative care, recent data indicate that the parallel involvement of a specialist palliative team that addresses the psychological, social, and spiritual needs of patients may be advantageous for both patients and their families. This mode of early integration of palliative care has been found to enhance patient quality of life and to provide more effective use of costly treatments. In Czech hospitals, however, this mode is rarely employed. Palliative care is usually perceived as an end-stage approach, which is initiated only when all other anticancer treatment modalities have been exhausted. This case describes the challenges and missed opportunities when palliative care was initiated late during the dying phase of a young female patient with metastatic colorectal cancer, and it discusses the potential benefits of early integration of palliative care.

Global epidemiology of gastrointestinal stromal tumours (GIST): A systematic review of population-based cohort studies.

BACKGROUND: Gastrointestinal stromal tumours (GISTs) are rare, yet the most common mesenchymal tumour within the digestive tract. Lack of diagnostic criteria and no specific code in the ICD system has prevented epidemiological evaluation except from overt malignant cases in the past. A global estimate of incidence and disease patterns has thus not been available. METHODS: A systematic literature search of all available population-based studies on GIST published between January 2000 and December 2014 were reviewed. Descriptive epidemiological data are presented. RESULTS: The search found 29 studies of more than 13,550 patients from 19 countries that reported sufficient data for regional or national population-based statistics. Age at diagnosis ranged from 10 to 100 years, with median age being mid 60s across most studies. Gender distribution was equal across studies. On average, 18% of patients had an incidental diagnosis (range from 5% to 40%). Anatomical location of primary tumour in 9747 GISTs demonstrated gastric location as the most frequent (55.6%) followed by small bowel (31.8%), colorectal (6.0%), other/various location (5.5%) and oesophagus (0.7%). Most studies reported incidence at 10-15 per million per year. Notably, lowest incidence was in China (Shanxi province) with 4.3 per million per year. Highest incidence rates were reported also from China (Hong Kong and Shanghai areas), and in Taiwan and Norway (Northern part), with up to 19-22 per million per year. CONCLUSIONS: Epidemiology of GIST demonstrates some consistent features across geographical regions. Whether the reported extreme differences in incidence reflect real variation in population risk warrants further investigation.

Influence of mutation type on prognostic and predictive values of TP53 status in primary breast cancer patients.

High rates of mutation in the TP53 tumor suppressor gene have been found in many human cancers, including breast tumors, making p53 one of the most studied proteins in oncology. However, the prognostic and predictive value of alterations in this gene remains ambiguous. To analyze the clinical value of somatic TP53 mutations, we collected clinical and molecular data on 210 women with primary breast cancer. We found significant associations of p53 mutations with tumor grade, metastasis, molecular subtype, Her2 status and inverse correlations with estrogen and progesterone receptor status. Cox proportional hazard analysis confirmed a strong prognostic value of p53 mutation for overall survival rate and highlighted significant interactions with lymph node involvement and tumor size. In relation to treatment options, TP53 mutations were associated with poor response to anthracyclines and radiotherapy. Categorization of TP53 mutations according to their type and location revealed that patients with nonsense mutation have the poorest prognosis in comparison with wild-type cases and other types of mutations in this gene. Classification of TP53 mutations with respect to the degree of disturbance of protein structure showed association of disruptive mutations with poorer patients' outcome in contrast to wild-type and non-disruptive mutations. In conclusion, the present study confirms p53 as a potential predictive and prognostic factor in oncology practice and highlights the growing evidence that distinct types of mutations have different clinical impacts.
