Outcome of surgical treatment of carcinoma of the pancreas

AIMS AND BACKGROUND: Pancreatic resections for neoplastic diseases have a high risk of severe intra- and postoperative complications and are associated with high mortality rates. They should be performed as a rule in centers specializing in this type of surgery. However, it is becoming increasingly likely that such tumors may have to be treated in surgery units which are not specifically dedicated to pancreatic surgery. The aim of this study was to assess the improvements in clinical results in a non-specialized general surgery setting in the light of the most recent progress in surgical techniques, drug treatments and nutritional support. METHODS AND STUDY DESIGN: We analyzed 48 patients with pancreatic cancer treated in our institution over the period from 1980 to 1998: 36 had cancer of the head of the pancreas, 5 of the ampulla, 1 in the second duodenal portion, and 6 of the body-tail. The operations performed consisted of 13 Whipple pancreaticoduodenectomies with cutting and stapling of the distal pancreatic stump at the level of the isthmus, 4 left pancreasectomies, 2 local resections of the ampulla, 21 palliative operations, and 2 exploratory laparotomies. RESULTS AND CONCLUSIONS: The patients were submitted to follow-up including clinical examinations, blood-chemistry tests, and instrumental investigations. The mean survival was 18 months in the cases where radical surgery was performed, compared to 11 months after palliative surgery. We conclude that an improved prognosis can obtain after pancreatic resection. This is attributable to a more accurate preoperative staging and to the aid of the various forms of nutritional support and pharmacological prophylaxis currently available.     

Computation of a radiodosage equivalent of the effect of bleomycin

The responses of in vitro cultured mammalian cells to X-rays and bleomycin were compared for establishing a general rule to convert X-ray dose to bleomycin dose for a given biological effect. There was no significant difference in the radiosensitivities according to cell lines used in this experiment, while the responses of cells to bleomycin varied from cell to cell. The X-ray dose-response curves for the cells were convex upward if plotted on a semilogarithmical scale, while bleomycin dose-response curves were convex downward. These results indicated that the ratio of X-ray dose and bleomycin dose required for a comparable biological effect would vary with the X-ray dose and from cell to cell. Preliminary treatment with bleomycin sensitized mammalian L5 cells to X-rays. When the cells were exposed to bleomycin following irradiation, no significant synergestic effect was observed, in spite of the fact that the bleomycin dose was sufficient to result in a survival of 4.5%.

The course of life of survivors of childhood cancer

The developmental consequences in adulthood of growing up with childhood cancer are not well understood. The Course of life questionnaire was developed to assess the attainment of developmental milestones retrospectively and socio-demographic outcomes in young adulthood. The aim of this study was to assess the course of life and socio-demographic outcomes in young adult survivors of childhood cancer. Knowledge about possible gaps in the course of life could enable health care providers to aim for the most favourable course of life. A total of 353 Dutch survivors and a comparison group of 508 peers without a history of cancer, all aged between 18 and 30, filled in the Course of life questionnaire. The course of life of the survivors was found to be hampered. The young adult survivors of childhood cancer in the Netherlands turned out to have achieved fewer milestones than their peers with respect to autonomy development, social development, and psycho-sexual development, or to have achieved the milestones when they were older than their peers. In addition, survivors displayed less risk behaviour than the comparison group. The survivors and the comparison group also differed on some socio-demographic issues. A considerably lower percentage of survivors than peers in the comparison group were married or living together, and/or employed. Their educational level, on the other hand, was as high as that of their peers.     

A Study of Clinicopathological Profile of Patients of Hoarseness of Voice Presenting to Tertiary Care hospital

Hoarseness is subjective term used to describe abnormal voice quality which may occur due to many causes because it is just a symptom. Proper knowledge and clinicopathological profile is important to treat the underlying pathology. This prospective study was carried out in 100 patients presented in Department of ENT, Gandhi Medical College, Bhopal from April 2013 to September 2014 with complaint of hoarseness of voice for more than 15 days. Objective of this study is to study incidence, duration and sex predilection for hoarseness of voice. Also to study different etiological and predisposing factors for hoarseness of voice. After taking detailed history of the patient, complete examination of ear, nose and throat has been carried out. Indirect laryngoscopy, direct laryngoscopy, FOFE is done. Any suspicious tissue is sent for histopathological evaluation. X-ray soft tissue neck and if required CT SCAN larynx is done. Out of 100 patients maximum were from 50 to 70 years age group. 89% were males while only 11% were females. Labourers (37%) and farmers (32%) were the major groups affected. Smoking habit found in 60% of patients and tobacco chewing in 33% of patients and both, also having. Most common cause for hoarseness was found out to be laryngeal neoplasms of which supraglottic growth being commonest (37%) in our study. Hoarseness of voice may be present due to various underlying pathologies. So proper diagnosis, through detailed history, clinical examination and investigations is warranted to find out the cause and starting treatment.     

Cytotoxicity of enantiomers of gossypol

The effect of gossypol on cell proliferation was studied using 24-well multiwell dishes. Cells were added to each well and incubated for 24 hours before the addition of different concentration of gossypol, which was dissolved in dimethyl sulfoxide immediately prior to use. After a further 3-day incubation, cell growth was determined by measuring cellular protein content. Standards and controls were included and dose response curves constructed by plotting increase in protein content over the 3-day growth period against gossypol concentration. Gossypol inhibited proliferation in tumor-derived cells as well as normal fibroblasts. BCL-D1 cells, a human diploid strain of fibroblasts, were sensitive to gossypol and further studies were undertaken using these cells. In contrast of most of the tumor-derived cells that have been used, these cells maintained consistent patterns of growth over periods of many months. The enantiomers of gossypol were prepared and analyzed as described in Matlin & Zhou (1984). The (-) enantiomer of gossypol was more cytotoxic than the (+) form. In the case of all the tumor-derived cells, the concentration of the (-) enantiomer required to produce cytotoxicity was -10% of that required in the case of the (+) enantiomer. At lower concentration, gossypol inhibited cellular proliferation, but at higher concentrations the compound was responsible for complete cell lysis. Even with high doses of (-), gossypol cell lysis did not occur rapidly. When gossypol was added to cultures and then removed with thorough washing at time intervals, it was found that 30 minute exposure was adequate to bring about the cytolytic effect. Thus, the biochemical effects of gossypol occurred rapidly after addition even though cellular changes may not be obvious for some hours. Once gossypol has been added to tissue culture medium, there is a loss of cytotoxic potential. When gossypol was added to culture fluid and incubated at 37 degrees Centigrade before addition to cells, the chemical lost -10%/hour of its cytotoxic potential. The likely explanation is a binding of gossypol to plasma proteins that form the serum supplement to the growth medium. More than 10,000 men have participated in clinical trials relating to the anti-fertility effects of gossypol; a low incidence of side effects has been reported. The question arises as to why gossypol fails to have an effect on bone marrow cell proliferation. Most likely the answer lies in the protection afforded by higher protein concentrations.

Analysis of load status and management strategies of main caregivers of patients with malignant tumors of digestive tract

Caregiver load refers to the subjective and objective negative impact of caregivers in the care of patients, and excessive load will have a serious impact on patients and caregivers themselves and can reduce their quality of life. For the main caregivers, it not only needs to care for the patients in life and daily life, but also needs to pay the cost of treatment for the patients, coupled with the need to carry out their own original work, life, etc. excessive life pressure, economic pressure, work pressure, emotional pressure, etc. lead to heavy load of the main caregivers, which can easily cause caregivers to have different degrees of psychological problems, which will cause serious adverse effects on the caregivers themselves and cancer patients, not conducive to the construction of a harmonious family and society. This article analyzes the current situation of primary caregiver burden in patients with gastrointestinal malignant tumors, analyzes its influencing factors, and specifies specific treatment strategies. It is hoped to provide scientific guidance for later related research and application.     

A Preliminary Survey of Oncologists' Perceptions of Quality of Life Information

Quality of life (QOL) of cancer patients has become the focus of increasing research in oncology, and a frequently measured endpoint in clinical trials. Very little attention has been paid to the perspective of physicians on quality of life information, and its role in clinical decision-making. This report describes the findings of research focused on exploring the perspectives of physicians about quality of life information that is available for cancer patients. On the basis of qualitative data gathered through in-depth interviews with 60 oncologists in the first phase of this project, we have developed a self-administered questionnaire (MD-QOL survey) designed to assess oncologists' views on QOL. This survey was administered to an international group of gynecologic oncologists. The objectives of this study were to assess the face validity of the initial items in the MD-QOL, to expand the pool of items, and to assess the feasibility of utilizing a self-administered questionnaire to assess physicians' perspectives on QOL information. Twenty-eight oncologists responded to the questionnaire. The majority of respondents felt that QOL can be measured and that it should be measured from the patient's own perspective. Half of the physicians felt that currently available QOL information is useful in clinical practice. Ninety-three percent of respondents felt that the greatest benefit of QOL information is ‘being able to treat the whole patient’. Forty one percent of respondents felt that length of survival is more important to patients than quality of life. However, only 7% of the respondents felt that the primary job of physicians is to save lives, and that QOL should not be a predominant concern for physicians. The inclusion of QOL in randomized trials was perceived as encouraging both patient and physician participation. The results of this survey are being used to further explore these critical issues. © 1997 John Wiley & Sons, Ltd.     

Economic burdens and quality of life of family caregivers of cancer patients

OBJECTIVES: We conducted this study to identify factors influencing the burdens cancer brings to a patient's family and to evaluate the association between the burdens and the caregiver's quality of life (QOL). METHODS: Participants were drawn from the primary family caregivers of cancer patients at 6 university hospitals and the National Cancer Center in Korea. Of the 738 eligible caregivers, 704 (95.4%) completed the questionnaire packets (Family Impact Questions and Caregiver's QOL-Cancer). RESULTS: Caregivers, who were poor (OR, 2.11; 95% CI, 1.44-3.10), whose health status was poor (OR, 1.87; 95% CI, 1.29-2.70), who were married (OR, 1.75; 95% CI, 1.12-2.72), who provided care for a long time (OR, 2.29; 95% CI, 1.59-3.28), who cared for patients with poor performance status (OR, 1.35; 95% CI, 1.00-1.82), and who paid high medical expenses (OR, 1.70; 95% CI, 1.21-2.40), were more likely to lose their family savings. In multiple regression analysis, most burden variables--including requiring caregiving assistance, major life change, inability to function normally, loss of savings, loss of income, and altered educational plans--were associated with caregiver QOL. Loss of family income, which was related to economic issues, was most strongly associated with it (16.0%). CONCLUSIONS: Our study suggests that to improve caregiver QOL, we should give priority to decreasing the economic burden that cancer places on patient's family.
