Depression and socio-economical burden are more common in primary caregivers of patients who are not aware of their cancer: TURQUOISE Study by the Palliative Care Working Committee of the Turkish Oncology Group (TOG).

In this study, we aimed to determine the personal, social and economic burden and the frequency of depression, as well as in caregivers of cancer patients who are being treated with chemotherapy in Turkey. The study is designed as a cross-sectional survey study using a 5-point Likert-type response scale, and the last part of the questionnaire includes the Beck Depression Inventory. The depression rate was found to be 64% (n = 476) among all subjects (n = 968), with 91% of those with depression demonstrating signs of mild depression. In this study, a significant difference was found between the presence of depression and age (young), sex (female), educational level (high), economic status (low), financial loss during treatment, patient's lack of knowledge about his/her diagnosis, metastatic disease and short survival time. In addition, 64% of all subjects had concerns of getting cancer, and 44% of all subjects had feelings of anger/rage against other people. In a multivariate regression analysis, the patient's lack of knowledge of the diagnosis was the independent risk factor. In conclusion, depression incidence and burden rate increased among cancer caregivers, and care burden was highly associated with depression. Accordingly, approaches to reducing the psycho-social effects of cancer should focus intensively on both the patients and their caregivers in Turkey.

The development of metachronous prostate cancer and chronic myeloid leukemia in a patient with metastatic rectal cancer.

We report herein an unusual case of metachronous triple cancers (rectum, prostate and Philadelphia(+) [Ph(+)] chronic myeloid leukemia [CML]). A metastatic rectal cancer was diagnosed in a 76-year-old male patient, who was treated with transanal tumor resection and chemotherapy. Thirty months from the initial rectal cancer diagnosis, prostate cancer was diagnosed and the patient was administered maximal androgen blockade and received palliative radiotherapy to the lumbar spine because of painful bone metastases. Thirty months after the diagnosis of rectal cancer and 12 months after the diagnosis of prostate cancer the patient developed Ph(+) CML and imatinib treatment was started. After one-year period in remission, CML evolved into accelerated phase and the patient died of intracranial hemorrhage.

Awareness of breast and cervical cancer risk factors and screening behaviours among nurses in rural region of Turkey.

Breast and cervical cancer are the most common causes of cancer mortality among women worldwide, but actually they are largely preventable diseases. There is limited data on breast and cervical cancer knowledge, screening practices and attitudes of nurses in Turkey. A self-administered questionnaire was used to investigate the knowledge and attitude of nurses on risk factors of the breast and cervical cancer as well as screening programmes such as breast self-examination (BSE), clinical breast examination, mammography (MMG) and papanicolaou (pap) smear test. In total, 125 out of 160 nurses participated in the study (overall response rate was 80.6%). The risk factors and symptoms of breast cancer was generally well known, except for early menarche (23.2%) and late menopause (28.8%). For cervical cancer, the correct risk factors mostly indicated by the nurses were early age at first sexual intercourse (56%), smoking (76%), multiple sexual partners (71.2%). As for screening methods, it was believed that BSE was a beneficial method to identify the early breast changes (84.8%) and MMG was able to detect the cancer without a palpable mass (57.6%). Little was known about the fact that women should begin cervical cancer screening approximately 3 years after the onset of sexual intercourse (23.2%) and if repeated pap smear test were normal, it could be done every 2-3 years. Most of the nurses considered that MMG decreases the mortality in breast cancer (65.6%) and also believed that pap smear test decreases the mortality in cervical cancer (75.2%). Despite high level of knowledge of breast cancer risk factors, symptoms and screening methods, inadequate knowledge of cervical cancer screening method were found among nurses.

5-fluorouracil increases the number and complexity of premature complexes in the heart: a prospective study using ambulatory ECG monitoring.

The cardiac toxicity of LV5FU2 (de Gramont) regimen which is a widely used chemotherapy regimen in gastrointestinal system cancers is not well defined. We aimed to evaluate the impact of this regimen on cardiac rhythm. Two Holter ECG recordings were obtained in all patients with gastrointestinal system cancers treated with LV5FU2 regimen as first-line chemotherapy (one before and the second during the first 24 h of chemotherapy). Records were reviewed for the heart rate, rhythm, atrial premature complexes (APC), ventricular premature complexes (VPC), grades according to Lown-Wolf grading system and ST segment changes. Holter ECG recordings were evaluated in 27 patients. In the baseline evaluation, neither clinical symptom nor ST segment changes were observed. During the treatment period, chest pain was observed in two patients without any cardiac enzyme and ST segment changes. Moreover, a decrease in mean heart rate, and an increase in the number and complexity of premature complexes secondary to treatment were observed. The mean heart rate, APC per hour and VPC per hour (+/-SD) before vs. during treatment were, respectively, 93.1+/-16.4 vs. 81.6+/-12.7 (p=0.001), 18.9+/-54.0 vs. 45.3+/-53.8 vs. (p=0.049) and 12.7+/-29.6 vs. 38.1+/-42.1 (p=0.002). LV5FU2 regimen leads to a decrease in mean heart rate and a significant increase in APC and VPC which may lead to serious arrhythmias. These effects must be better understood for a safer administration of this useful and widely used drug regimen.

Bax, bcl-2 and c-kit expression in non-small-cell lung cancer and their effects on prognosis.

In non-small-cell lung cancer (NSCLC), stage of the disease is still the most important prognostic factor. Other than stage, many biological markers and many other prognostic factors are studied to define their effects on prognosis of lung cancer. In this study, we aimed to evaluate the expressions of Bax and bcl-2 genes which are important in apoptosis and c-kit, which is a tyrosine kinase transmembrane receptor, as well as searched their response to treatment modalities and effects on survival. Sixty-nine NSCLC cases' pathological samples were stained with specific Bax, bcl-2 and c-kit dyes by immunohistochemical (IHC) methods. IHC evaluation was done by the semichantitative method according to the distribution and intensity of the staining. Twelve of 69 cases (17.4%) were stage I, 28 (40.5%) were stage II, 17 were (24.6%) stage IIIA, nine cases were (13.1%) stage IIIB and three cases (4.4%) were stage IV patients. Their histological subtypes were as follows: of 69 cases, 36 (52.2%) were squamous cell carcinoma, 28 (40.6%) were adenocarcinoma, five (7.2%) were adenosquamous cell carcinoma (two patients) and large-cell carcinoma (three patients). The positive immunostaining rates for Bax and bcl-2 in whole group, squamous cell carcinoma and adenocarcinoma groups were 40.6%/36.2%, 55.6/69.4% and 25.0/0.0%, respectively. The positive immune staining rates for c-kit in whole group, squamous cell carcinoma and adenocarcinoma groups were 7.2, 5.6 and 7.1%, respectively. We didn't find any correlation with Bax, bcl-2 and c-kit expressions and clinicopathological parameters such as age, tumour size, lymph node involvement, smoking, stage of the disease, response to radiotherapy and chemotherapy. Results are interpreted according to survival; bax and bcl-2 expressions were not so effective both in whole group and histologically subgrouped patients. C-kit expression was also found not related with survival in whole group whereas found as a bad prognostic factor in patients with squamous cell carcinoma. These findings could indicate that the expression of apoptotic pathway markers and c-kit may have a role in the prognosis of early stage NSCLC, especially with squamous cell carcinoma subtype.

Lower motor neuron disease associated with myelofibrosis.

We present a patient who has signs pointing to the involvement of lower motor neurons and myelofibrosis. To our knowledge, unlike lymphoproliferative disorders, co-occurrence of myelofibrosis and lower motor neuron disease (MND) has not been reported so far. A 64-year-old male patient was admitted to our hospital with the complaint of painful cramps in his neck and forearms. On physical examination marked hepatomegaly and splenomegaly were found. On neurologic examination nasal quality of the voice and slight palatal weakness were detected. There were generalised slight weakness and atrophy in both proximal and distal muscle groups. Fasciculations were observed especially in forearm muscles and it was observed that he had been avoiding head movements because of painful muscle cramps. Deep tendon reflexes were hypoactive. Nerve conduction studies were normal. By needle electromyography, giant motor unit action potentials (amplitudes up to 8 mV), fibrillation potentials, positive sharp waves and fasciculation potentials were detected in all muscles which were investigated. A hypercellular bone marrow (100%) was determined by bone marrow biopsy. In addition to increased production of the myeloid and megakaryocytic lines, abnormal aggregation and grouping of megakaryocytes were seen. Reticular fibers were increased. He had some benefit of dyphenilhydantoin treatment given for the painful cramps in his neck and forearm muscles. Hydroxyurea treatment was started for myelofibrosis. Six months later, his general condition was better, and the painful cramps were completely resolved. No marked deterioration has been detected in neurologic examination and electromyography for 1 year.
