Personalized treatment in oncology is the most innovative method of care. The best method to establish personalized treatment is by genetic characterization of the malignant cell. Theoretically, the more detailed the characterization, the more effective the choice of treatment becomes. Currently, there are fast and relatively low-cost options that allow such genetic characterization. However, test results sometimes do not detect targetable alterations and, even if they do detect, the use of the treatment-alteration combination does not always generate a satisfactory oncological response. The present paper aims to answer two questions. First, how targetable can the most common gene alterations in colorectal cancer be. Second, whether it makes sense to use broad molecular testing as a standard in all metastatic patients.

There is ongoing debate regarding the role of neck dissection in differentiated thyroid cancer, about its usefulness in elective settings, and the increased costs regarding morbidity and operative time. This retrospective study aimed to determine the rate of metastases in cervical lymph nodes, to examine the morbidity of this surgery, and to assess whether a pattern of distribution of tumor cells concerning neck lymphatic compartments exists. The most frequent type of cancer to metastasize was papillary cancer, the majority of patients were young with a median of 30 years, predominantly females. Differentiated thyroid cancer frequently metastasizes to the central and lateral compartments of the neck. The morbidity is minimal in a high-volume center. Radical neck dissection is safe and feasible in selected patients with confirmed invaded or enlarged lymph nodes due to differentiated thyroid cancer, and postoperative complications are minimal if the anatomy is correctly identified and the cases strictly selected.

Introduction. The latest histological classification of lung adenocarcinoma includes lepidic, acinar, papillary, micropapillary, and solid as subtypes. Testing these subtypes for their prognostic and predictive value is an ongoing scientific challenge. The present research article aims to describe the influence this classification has on patient survival. Materials and Methods. Thirty-three patients were included in the trial. The most important enrollment criterion was the clear specification of the adenocarcinoma subtype in the pathology report. Patients were stratified into three groups which included the adenocarcinoma pathological subtypes as follows: lepidic (LEP), acinar and papillary (ACN/PAP), and micropapillary/solid (MIP/SOL). The primary endpoint was progression-free survival. Other endpoints included overall survival. Results. The lepidic subtype of ADC had superior PFS and OS, regardless of stage. Papillary and acinar subtype showed an intermediate prognosis, whereas micropapillary and solid subtypes were the most aggressive. Conclusions. The experience of this single center confirmed data in the literature. Further studies are needed to demonstrate all the possible implications of this pathology classification.

Background. This study evaluated the difference between boys and girls in terms of nutritional status, lifestyle, and dietary habits during school life. Materials and Methods. A descriptive and observational study was conducted in 2016, in which 251 children, aged 7-17, from 3 elementary schools and a high school inBucharest,Romania, were evaluated. A questionnaire was used to assess food behavior, eating, and lifestyle habits. Results. Boys had a significantly higher waist circumference (71.18±9) than girls (67.46±9.91) (p=0.004). Thus 27% of boys were overweight or obese compared with only 22% of the girls. Differences were also seen between the two groups in terms of main meals and snacks and following a rhythm of meals: a statistically significant percentage of girls (36.3%) skip breakfast, while most boys (63.8%) take a food package to school. A total of 23.8% of the boys and 24% of the girls state that they eat while sitting in front of the computer or TV. Conclusions. We found that boys are more overweight or obese than girls. Obesity in the pediatric population of Romania could be explained by the country’s emergence from communism 25 years ago, pattern typical of all Eastern European countries and which currently involve an overexposure of people to fast food, fizzy drinks and sweets, as well as to a high consumption of salt and food additives. Unbalanced and highly caloric food had been preferable to healthy food in the last period. Leisure time is rather spent in front of the TV, tablet, detrimental to rational physical exercise, recreational sports or hiking. The family environment is very important and all our actions should be focused on continuous education about the risks of unhealthy food and a sedentary lifestyle.

Microsatellite instability (MSI) is a feature of colorectal tumors that develops as a result of inactivation of the DNA mismatch repair system. It is found in about 15% of all colorectal cancers and is an important prognostic molecular marker when assessing patients with colorectal cancer. It can influence prognosis and treatment decisions in both the advanced and early stages. Although in early stages this marker suggests a favorable prognosis and presents an important argument against adjuvant treatment in stage II disease, in metastatic stages it no longer associated with such an optimistic outcome. The present trial is a prospective, single-center study which included 122 colorectal cancer patients who were tested for MSI using immunohistochemistry. The trial included patients with stage II to IV colorectal cancer, treated in the Prof. Dr. Agrippa Ionescu Emergency Hospital, Bucharest, Romania. Follow-up data were collected during a 24-month period. The study attempted to determine whether differences exist in overall survival for MSI (microsatellite instability) vs. MSS (microsatellite stable) colorectal cancer and to ascertain whether sex of the patient influences prognosis in MSI patients, irrespective of stage or treatment. Results demonstrated no significant differences in survival for MSI vs MSS colorectal patients, and patients’ gender proved not to influence the outcome in MSI patients.

The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative risk for each sex to develop thyroid carcinoma. The incidence of thyroid carcinoma was higher for women than for men, with a higher relative risk in the female subgroup. Incidence was also highest in the 50-60-year-old group. Given that studies show better survival for women and for younger patients, even when presenting with advanced disease, compared with older, male patients, such prognostic indicators should be a factor in the treatment decision.
