Increasing physical activity level during and after treatment is recommended by the American Cancer Society because of the many benefits namely reducing fatigue and improves psychological distress which leads to an improvement in the quality of life. This study is aimed to compare physical activity level and body composition between oncology patients who are still undergoing treatment and those on medical follow-up. Patients were recruited based on convenience sampling from the Oncology Outpatient Clinics of Universiti Kebangsaan Malaysia Medical Center (UKMMC). Anthropometric measurements and body compositions were measured using calibrated tools while physical activity level were assessed using Global Physical Activity Questionnaire (GPAQ). Medical treatment history was obtained from patients medical records. A total of 53 patients (n=38 were undergoing treatment and n=15 was on follow-up) consisting of Malays (54.7%) and Chinese (45.3%) and with mean age of 55.3 ± 9.3 years. Most patients were previously diagnosed with ovarian cancer (39.6%) and colon cancer (18.9%) patients and they were at cancer stage III (18.8%). Body mass index (BMI) and percent fat mass were significantly different (p<0.05) between patients undergoing treatment (22.8 ± 2.7 kg/m2, 28.7 ± 7.2%) and on follow-up (26.2 ± 5.5 kg/m2, 37.1 ± 11.9%). Majority of the patients undergoing treatment were categorized under low physical activity compared to those on follow-up (p<0.05). Physical activity level measured as METS-minutes/week is also found to be significantly different (p<0.05) between patients on treatment and follow-up. As a conclusion, cancer patients undergoing treatment have low physical activity, with lower BMI and fat mass compared to those on follow-up. This is consistent with their nature of living where during treatment the patients will resting while coping with side effects of treatments.

Human papillomavirus (HPV) is a necessary cause of cervical cancer and its precursors. Increased
expression of high-risk hrHPV viral oncogenes in abnormal cells might increase the expression of
p16INK4a. We aimed to determine the role of p16INK4a in detecting hrHPV-transformed epithelial
cells in liquid-based cervical cytology, and compared the results with hrHPV DNA testing by realtime
polymerase chain reaction (RT-PCR). Fifty-seven cytological samples were tested for p16INK4a
immunomarker and hrHPV DNA. Test performance of both tests was determined by comparing
sensitivity, specificity and predictive values using available histological follow-up data as gold
standard. Of 57 samples, 36 (63.2%) showed immunoreactivity for p16INK4a and 43 (75.4%) were
hrHPV-infected. A fairly low concordance rate (k = 0.504) between p16INK4a immunolabelling
and hrHPV DNA status was noted. For prediction of cervical intraepithelial neoplasia (CIN) II and
worse lesions, p16INK4a had a sensitivity and specificity of 93.5% and 60%; whereas hrHPV DNA
testing had a sensitivity and specificity of 100% and 20%. Dual testing by combining p16INK4a
and hrHPV showed sensitivity and specificity of 100% and 33.3%. In conclusion, p16INK4a is
useful in predicting severity of the cytological abnormalities. Although p16INK4a is more specific
but less sensitive than hrHPV in detecting high-grade cervical lesions, a combination of both tests
failed to demonstrate significant improvement in diagnostic sensitivity, specificity and predictive
value. Larger-scale prospective studies are required to assess further whether this biomarker should
be routinely used as primary screening tool independently or in combination with hrHPV testing to
improve diagnostic accuracy in cervical cytology.
