Perceived Barriers to Symptoms Management among Family Caregivers of Cancer Patients.

INTRODUCTION: Caring for patients with advanced disease involves many concerns for caregivers. All aspects of health of the caregiver is compromised in the process of caring for the cancer patients. Usually, most of the terminally ill cancer patients live with their caregivers at home. OBJECTIVES: The aims of the present study was to identify the barriers to symptom management among caregivers of cancer patients and to find the association between perceived barriers to symptom management of caregivers' with their demographic variables and their patients' disease-related variables. MATERIALS AND METHODS: A descriptive study was conducted among 768 family caregivers (FCGs) of cancer patients, and they were selected using convenient sampling technique. Data was collected from caregivers who were caring for their beloved one at least 2-3 h/day and who were above 20 years of age. Data was collected through a structured interview using barriers questionnaire and demographic pro forma after obtaining the consent from the caregivers. RESULTS: The result shows that among 768 FCGs, 216 (28.1%) of them were in the age group between 31 and 40 years and most of them were spouses (45.6%). The perceived barriers of caregivers were less confidence on the management of symptoms. A total of 423 (55.1%) had lack of awareness about pain assessment and management of cancer by 681 (88.6%). Majority, i.e., 654 (85.1%) of them had financial problems in the family. CONCLUSION: FCGs take the major responsibilities both at the hospital and at home in caring for the cancer patients. Since FCGs had lack of knowledge on caring of cancer patients, there is a need for awareness program on the assessment and management of symptoms among cancer patients.

Quality of Life among Cancer Patients.

INTRODUCTION: Cancer is a leading cause of death. People living with cancer experience a variety of symptoms. Quality of life (QOL) is a major concern of patients with terminal cancer. Symptoms affect their QOL. Management of symptoms improves distress and QOL. OBJECTIVE: The objective of the study was to assess the QOL among cancer patients. MATERIALS AND METHODS: A survey was conducted among 768 cancer patients selected by a convenient sampling technique. Data was collected from cancer patients by interview technique using structured and validated interviewed schedule. RESULTS: Out of 768 cancer patients, 30.2% patients were in the age group of 51-60 years, majority with head-and-neck cancer (40.1%), and 57.7% had stage III disease. QOL of majority of patients was influenced by their symptoms. 82.3% of them had low QOL scores. CONCLUSION: Cancer patients experienced many symptoms that affected their QOL. There is a need to develop interventions for effective management of symptoms that will empower the patients to have a greater sense of control over their illness and treatment and to improve the QOL.

Emotional Aspects and Pranayama in Breast Cancer Patients Undergoing Radiation Therapy: A Randomized Controlled Trial.

OBJECTIVE: Emotional disturbances are commonly experienced by cancer patients. The aim of this study was to determine the effectiveness of certain Pranayama techniques on the emotional aspects such as impatience, worry, anxiety, and frustration among breast cancer patients undergoing radiation therapy in India. METHODS: The study was conducted as a randomized controlled trial. Patients were recruited when they were seeking radiation therapy for breast cancer. They were allocated into two groups using block randomization technique. The experimental group performed Pranayama along with radiation therapy, whereas the control group received only routine care. RESULTS: Emotional aspects of the two groups were compared at the end of the treatment. Mann-Whitney U-test was used for comparison as the data were not following normality. It showed a significant difference between the two groups with the group who performed Pranayama showing a lesser mean score for these negative emotions. CONCLUSIONS: Pranayama might help in controlling the negative emotions likely to be faced by breast cancer patients, and it can be used as a supportive therapy for breast cancer patients receiving radiation therapy.

The prognostic implication of the expression of EGFR, p53, cyclin D1, Bcl-2 and p16 in primary locally advanced oral squamous cell carcinoma cases: a tissue microarray study.

Oral squamous cell carcinomas comprise a heterogeneous tumor cell population with varied molecular characteristics, which makes prognostication of these tumors a complex and challenging issue. Thus, molecular profiling of these tumors is advantageous for an accurate prognostication and treatment planning. This is a retrospective study on a cohort of primary locally advanced oral squamous cell carcinomas (n = 178) of an Indian rural population. The expression of EGFR, p53, cyclin D1, Bcl-2 and p16 in a cohort of primary locally advanced oral squamous cell carcinomas was evaluated. A potential biomarker that can predict the tumor response to treatment was identified. Formalin-fixed paraffin-embedded tumor blocks of (n = 178) of histopathologically diagnosed cases of locally advanced oral squamous cell carcinomas were selected. Tissue microarray blocks were constructed with 2 cores of 2 mm diameter from each tumor block. Four-micron-thick sections were cut from these tissue microarray blocks. These tissue microarray sections were immunohistochemically stained for EGFR, p53, Bcl-2, cyclin D1 and p16. In this cohort, EGFR was the most frequently expressed 150/178 (84%) biomarker of the cases. Kaplan-Meier analysis showed a significant association (p = 0.038) between expression of p53 and a poor prognosis. A Poisson regression analysis showed that tumors that expressed p53 had a two times greater chance of recurrence (unadjusted IRR-95% CI 2.08 (1.03, 4.5), adjusted IRR-2.29 (1.08, 4.8) compared with the tumors that did not express this biomarker. Molecular profiling of oral squamous cell carcinomas will enable us to categorize our patients into more realistic risk groups. With biologically guided tumor characterization, personalized treatment protocols can be designed for individual patients, which will improve the quality of life of these patients.

Adjuvant treatment for Stage I seminoma: Why radiotherapy is better than carboplatin.

Adjuvant treatment options for Stage I seminoma include active surveillance, chemotherapy, and radiotherapy. Active surveillance may not be ideal for the average Indian patient. Of the two accepted adjuvant therapy options, namely single-dose carboplatin chemotherapy and radiotherapy to the retroperitoneal nodes, though it intuitively appears more appealing, a deeper review reveals the potential drawbacks of chemotherapy. This article highlights the misconceptions regarding carboplatin and provides reasons for an argument why radiotherapy is better when a patient with Stage I seminoma chooses to undergo adjuvant treatment.

Symptoms experienced by cancer patients and barriers to symptom management.

BACKGROUND: People living with cancer experience wide variety of symptoms. If symptoms are not managed well, it may hamper an individual's ability to continue his or her activities of daily life. Treatment of symptoms relieves suffering and improves the rate of recovery as well as the quality of life. OBJECTIVES: To assess the symptoms of suffering among cancer patients and to identify the perceived barriers to their symptom management. MATERIALS AND METHODS: A cross-sectional study was carried out among 768 cancer patients selected by stratified sampling with a proportionate selection from each stratum. Data were collected from cancer patients by interview technique using structured validated questionnaire. RESULTS: Majority of the samples (30.2%) belonged to the age group of 51-60 years, most of them were diagnosed with head and neck cancer (40.1%) and 57.7% had stage III disease. The majority of the patients studied had pain (77%), tiredness (96.5%), disturbed sleep (96.4%), weight loss (63.3%), and irritability (85.7%). Most of the patients had lack of appetite (89.4%), feeling of sadness (96.6%), worry (94.5%), and feeling of nervousness (82.8%). Majority of the patients had some misconception regarding symptoms, that is, increasing pain signifies disease progression (92.7%), medicine to control pain may weaken the immune system (89.9%) and pain is inevitable for cancer patients (78.5%). Seventy-seven percent of samples reported that the anxiety or depression is expected after the diagnosis of cancer. CONCLUSION: This study provides an overview of symptoms among cancer patients and barriers experienced by them.

Nimotuzumab provides survival benefit to patients with inoperable advanced squamous cell carcinoma of the head and neck: a randomized, open-label, phase IIb, 5-year study in Indian patients.

OBJECTIVE: Overexpression of epidermal growth factor receptor (EGFR) in many cancers makes it an attractive therapeutic target. This study evaluated the clinical utility of nimotuzumab, a monoclonal anti-EGFR antibody, used concurrently with radiotherapy (RT) and chemoradiotherapy (CRT) in squamous cell carcinoma of the head and neck (SCCHN). METHODS: This open-label study randomized 92 treatment-naïve patients (1:1) with advanced SCCHN into chemoradiation (CRT ± nimotuzumab) or radiation (RT ± nimotuzumab) group by investigator's discretion; these were further randomized into CRT + nimotuzumab or CRT and RT + nimotuzumab or RT groups, respectively. Treatment included 6 cycles each of cisplatin (50 mg/week), nimotuzumab (200 mg/week), and RT (total dose, 60-66 Gy). Response (tumor size reduction) was assessed at Month 6 post-treatment and survival, at Month 60. RESULTS: Forty and 36 patients in the chemoradiation and radiation groups, respectively (intent-to-treat population) were evaluated. Overall response at Month 6 post-treatment was 100% with CRT + nimotuzumab, 70% with CRT, 76% with RT + nimotuzumab, and 37% with RT. At Month 60, overall survival was 57% with CRT + nimotuzumab, 26% with CRT (P = 0.03), 39% with RT + nimotuzumab, and 26% with RT (P > 0.05). Median overall survival was not reached for CRT + nimotuzumab; it was 21.94 months for CRT (P = 0.0078), 14.36 months for RT + nimotuzumab, and 12.78 months for RT (P = 0.45). Risk of death was 64% lower with CRT + nimotuzumab than with CRT (95%CI: 0.37, 1.56), and 24% lower with RT + nimotuzumab than with RT (95%CI: 0.16, 0.79). Thus nimotuzumab was safe and well tolerated with few mild to moderate self-limiting adverse events. CONCLUSION: Concurrent use of nimotuzumab with CRT/RT is safe and provides long-term survival benefit.

Effect of exercise training on functional capacity & quality of life in head & neck cancer patients receiving chemoradiotherapy.

BACKGROUND & OBJECTIVES: Patients with head and neck cancer (HNC) undergoing chemoradiotherapy (CRT) suffer from fatigue causing a decrease in functional capacity and quality of life (QoL). Limited research in the field of exercise training among these patients demanded the need for this study to assess the effects of exercise training on functional capacity and quality of life. METHODS: A randomized controlled trial was conducted on 48 patients with HNC undergoing CRT. The exercise group received an individually tailored, supervised, exercise programme for six weeks, while the control group did not receive any form of exercise. Functional capacity and QoL were assessed at baseline and at the end of the intervention using the six minute walk distance (6MWD) and medical outcomes survey short form 36 (SF 36). RESULTS: The mean age of patients was 52 yr with 42 males. After six weeks, the 6MWD improved by 42 metres (P<0.05) in the exercise group while the control group showed a decrease by 96 metres (P<0.001). There was an improvement on the mental component score (MCS) of SF36 for the exercise group (4.8; P<0.05) and the physical component score (PCS) remained almost the same, while a decrease in PCS and MCS was seen in the control group (-5.9; P=0.064 and -17.3; P<0.05). When 6MWD and SF36 were compared between the groups, there was a statistically significant difference (P<0.001) seen after six weeks. INTERPRETATION & CONCLUSIONS: Our results showed that the functional capacity and QoL decreased among those not receiving a supervised exercise program, while exercise training improved functional capacity and QoL in HNC patients undergoing CRT.

Non-Hodgkin's lymphoma: is India ready to incorporate recent advances in day to day practice?

BACKGROUND: Non Hodgkin's Lymphoma (NHL) cure rates are increasing and morbidities are decreasing, with more active pharmacological agents and technological advancements. In spite of this, India is still battling with the prejudices of an economically and educationally impoverished patient base. METHODS AND RESULTS: We analyzed NHL cases from 2000 to 2006 using data from case sheets. Of 303 cases, only 100 patients had complete workup and received some form of treatment. For 203 patients, reasons for non-compliance were: financial constraint (119), distance from center (38), inability of physician to provide guarantees of cure (13), poor prognosis/fear of recurrence (28)), preferences for alternate medicine (5). Most common investigations that could not be afforded for staging were whole body CT scans and bone marrow aspiration and biopsy. Thirteen patients were in stage III and 53 in Stage IV. The most common regimen was CHOP (Cyclophosphamide, Adriamycin, Vincristine, Prednisolone). Forty-five patients did not complete six courses of CHOP and 35 patients had significant delay. Reasons for delay were intermittent availability of cash (35), intolerable toxicities (30), absence of supportive care (21), given-up attitudes (17). Eighty-three patients suffered Grade III/IV debilitating toxicities. Overall survival at five years was 50%. CONCLUSIONS: NHL in India is no different from the developed world. However, there are disparities in survivorship and outcomes, due to un-affordability and attitudes of the patients. Therefore, we suggest the development of Community Health Insurance Schemes (CHIs), with the hospital as the nodal center to address the above mentioned issues.

Diffuse large B-cell lymphoma of the uterine cervix: a rare case managed novelly.

Non-Hodgkin's lymphoma (NHL) of the uterine cervix is exceedingly rare. The management of the disease is not standardized. A 44-year-old lady presented with a history of bleeding pervaginum and a foul-smelling discharge of 2 months' duration. A 7 x 7 growth was seen in the cervix. A biopsy revealed it to be a CD20-positive diffuse large B-cell (DLBCL)-type NHL. She was diagnosed as stage IE after staging work-up, and managed with three courses of rituximab, cyclophosphamide, vincristine, adriamycin, and prednisolone followed by external beam radiotherapy (46 Gy in 23 fractions) by 3D conformal technique. She attained a complete response, and has been in remission for 1 year 3 months.

An overview on applications of optical spectroscopy in cervical cancers.

Despite advances in the treatment modalities, cervical cancers are one of the leading causes of cancer death among women. Pap smear and colposcopy are the existing screening methods and histopathology is the gold standard for diagnosis. However, these methods have been shown to be prone to reporting errors, which could be due to their subjective interpretation. Radiotherapy is the mainstay of treatment for the locally advanced stages of cervical cancers. The typical treatment regimen spans over 4 months, from the first fraction of radiation to clinical assessment of tumor response to radiotherapy. It is often noticed that due to intrinsic properties of tumors, patients with the same clinical stage and histological type respond differently to radiotherapy. Hence, there exists a need for the development of new methods for early diagnosis as well as for early prediction of tumor radioresponse. Optical spectroscopic methods have been shown to be potential alternatives for use in cancer diagnosis. In this review, we provide a brief background on the anatomy and histology of the uterine cervix and the etiology of cervical cancers; we briefly discuss the optical spectroscopic approach to cervical cancer diagnosis. A very brief discussion on radiation therapy and radiation resistance is also provided. We also share our experiences with the Raman spectroscopic methodologies in cervical cancer diagnosis as well as in the prediction of tumor radioresponse.

Prediction of radiotherapy response in cervix cancer by Raman spectroscopy: a pilot study.

Radiotherapy is the choice of treatment for locally advanced stages of the cervical cancers, one of the leading female cancers. Because of intrinsic factors, tumors of same clinical stage and histological type often exhibit differential radioresponse. Radiotherapy regimen, from first fraction of treatment to clinical evaluation of response, spans more than 4 months. Clinical assessment by degree of tumor shrinkage is the only routinely practiced method to evaluate the tumor response. Hence, a need is created for development new methodologies that can predict the tumor response to radiotherapy at an early stage of the treatment which can lead to tailor-made protocols. To explore the feasibility of prediction of tumor radioresponse, Raman spectra of cervix cancer tissues that were collected before (malignant) and 24 h after patient was treated with 2nd fraction of radiotherapy (RT) were recorded. Data were analyzed by Principal Components Analysis (PCA) and results were correlated with clinical evaluation of radioresponse. Mean Raman spectra of RT tissues corresponding to different levels of tumor response, complete, partial, and no response, showed minute but significant variations. The unsupervised PCA of malignant tissues failed to provide any classification whereas RT spectra gave clear classification between responding (complete and partial response) and nonresponding conditions as well as a tendency of separation among responding conditions. These results were corroborated by supervised classification, by means of discrimination parameters: Mahalanobis distance and spectral residuals. Thus, findings of the study suggest the feasibility of Raman spectroscopic prediction of tumor radioresponse in cervical cancers.

Efficacy of He-Ne Laser in the prevention and treatment of radiotherapy-induced oral mucositis in oral cancer patients.

OBJECTIVE: The objective of this study was to evaluate the efficacy of low-level lasers for the prevention and treatment of radiotherapy-induced oral mucositis in oral cancer patients. MATERIAL AND METHODS: Twenty-four hospitalized patients with oral cancer, scheduled to undergo radiotherapy at KMC, Manipal, were enrolled in the present study and assigned to laser (Group I)/control group (Group II). They were treated using He-Ne laser (lambda = 632.8nm, output = 10 mW and energy density = 1.8 J/cm(2)). Patients were subjected to treatment using laser scanner for 8 days and subsequently were treated using laser probe at 6 anatomic sites in the oral cavity for 5 minutes each. The patients were evaluated on each day of treatment for pain severity (NRS), functional impairment (FIS), and oral mucositis (RTOG) and were followed until the end of cancer treatment. Statistical analysis was done using SPSS version 10. RESULTS: Laser therapy applied prophylactically during radiotherapy can reduce the severity of oral mucositis, severity of pain, and functional impairment.

Survey of palliative care concepts among medical students in India.

BACKGROUND: Students must develop a "tension for change" before new material is learned. Therefore, a needs assessment generally precedes curriculum change in order to identify what the target population thinks they already know about a subject. Undergraduate medical education in India is a 4(1/2) -year course. This is followed by a 1-year internship before the new physician can practice independently. AIM: To assess the level of awareness in palliative care concepts among final-year students at Kasturba Medical College, Manipal, India. MATERIALS AND METHODS: One hundred eleven final-year students participated in a survey study 6 months before graduation. The data were collected after the survey and the responses were analyzed. RESULTS: The reported theoretical knowledge of palliative care concepts was better than the level of confidence in performing practical aspects of palliative care. CONCLUSION: Before this survey, we hypothesized that medical students in India would have low levels of self-reported understanding of palliative care and its components. In contrast, they reported a high level of understanding of palliative care but very little understanding and confidence in performing the associated skills. From this, we conclude that these medical students are ready for instruction in the practical skills of palliative care.

Survey of palliative care concepts among medical interns in India.

BACKGROUND: Medical knowledge, if theoretical, will fade away if not reinforced especially if not clinically implemented. We conducted a survey study amongst interns to assess awareness and confidence of common palliative care issues. Undergraduate medical education in India is a 4(1/2) -year course. This is followed by a 1-year internship before the new physician can practice independently. AIM: To compare the level of awareness in palliative care concepts among interns to that of final-year medical students at Kasturba Medical College, Manipal, India. MATERIALS AND METHODS: Forty-four interns participated in a survey study. The data were collected after the survey and the responses were analyzed. We compared these data with those obtained from conducting the same survey among medical students. RESULTS: The reported theoretical knowledge of palliative care concepts was better than the level of confidence in performing practical aspects of palliative care. The interns, overall, did not out-perform the students. CONCLUSION: Before this survey, we hypothesized that interns in India would have low levels of self-reported understanding of palliative care and its components. We were hoping to see an improvement in knowledge and confidence with training. In contrast, there was not much of an improvement but rather a decline in some areas. From this, we conclude that when medical students become interns, they need reinforcement of knowledge and more hands-on experience.

Vibrational spectroscopy studies of formalin-fixed cervix tissues.

Optical histopathology is fast emerging as a potential tool in cancer diagnosis. Fresh tissues in saline are ideal samples for optical histopathology. However, evaluation of suitability of ex vivo handled tissues is necessitated because of severe constraints in sample procurement, handling, and other associated problems with fresh tissues. Among these methods, formalin-fixed samples are shown to be suitable for optical histopathology. However, it is necessary to further evaluate this method from the point of view discriminating tissues with minute biochemical variations. A pilot Raman and Fourier transform infrared (FTIR) microspectroscopic studies of formalin-fixed tissues normal, malignant, and after-2-fractions of radiotherapy from the same malignant cervix subjects were carried out, with an aim to explore the feasibility of discriminating these tissues, especially the tissues after-2-fractions of radiotherapy from other two groups. Raman and FTIR spectra exhibit large differences for normal and malignant tissues and subtle differences are seen between malignant and after-2-fractions of radiotherapy tissues. Spectral data were analyzed by principal component analysis (PCA) and it provided good discrimination of normal and malignant tissues. PCA of data of three tissues, normal, malignant, and 2-fractions after radiotherapy, gave two clusters corresponding to normal and malignant + after-2-fractions of radiotherapy tissues. A second step of PCA was required to achieve discrimination between malignant and after-2-fractions of radiotherapy tissues. Hence, this study not only further supports the use of formalin-fixed tissues in optical histopathology, especially from Raman spectroscopy point of view, it also indicates feasibility of discriminating tissues with minute biochemical differences such as malignant and after-2-fractions of radiotherapy.

Evaluation of intraperitoneal vincristine in malignant peritoneal effusion.

The efficacy and safety of intraperitoneal administration of vincristine sulphate was determined in mice bearing Ehrlich ascitic carcinoma. The tumor bearing animals were administered with 0.5 mg/kg body weight (b.wt) of freshly prepared vincristine sulphate intraperitoneally on day 6 after tumor transplantation followed by drug administration once daily 5 days a week consecutively. The observations regarding the survival, alteration in the volume of peritoneal fluid, increase in life span and pathological changes in the liver, kidney, gastrointestinal tract and bone tissues were made. The vincristine sulphate treatment reduced the malignant cell population significantly and there were no significant changes in the histological picture of liver, kidney, bone, except the intestine, where atropy of villi demonstrating nests and cords of uniform small round cells were observed. Our experimental data suggests that intraperitoneal administration of vincristine is beneficial in malignant peritoneal effusion.

Evaluation of micronuclei frequency in the cultured peripheral blood lymphocytes of cancer patients before and after radiation treatment.

The frequency of micronucleated binucleate lymphocyte (MNBNC) was determined in the peripheral blood lymphocytes of patients suffering from various types of cancer before the onset of radiation treatment, middle (mid-) of the treatment and after completion of the treatment (post-treatment). The frequency of micronuclei increased significantly in the pretreatment sample of cancer patients when compared with the normal untreated healthy volunteers. During the middle of the radiotherapy an approximate two or > two-fold increase was observed in the micronuclei frequency in most of the patients when compared with the concurrent pretreatment samples. Immediately after the completion of treatment, the frequency of micronuclei further increased, and this increase was significantly higher than that of pretreatment and mid-treatment samples. Out of 27 patients analyzed, only nine patients did not have any history of smoking, tobacco chewing or alcohol consumption, while the remaining 18 patients had a history of either smoking, tobacco chewing or alcohol consumption or combination of two or all habits at the time of blood collection.

Vincristine (Vinca-alkaloid) as a sclerosing agent for malignant pleural effusions.

Vincristine, extracted from Vinca rosea Linn., is an effective antineoplastic chemotherapeutic drug used in oncology practice. This drug has never been used as a sclerosing agent for the treatment of malignant pleural effusion for reasons unknown. A study was conducted to examine the use of Vinca-Alkaloid as a sclerosing agent (pleurodesis) for the palliative treatment of malignant pleural effusions. The study included 15 patients, all diagnosed to have cytology-proven malignant pleural effusions. Intercostal tube drainage followed by chemical sclerotherapy with 2 mg vincristine was performed on all patients and a high success rate was noted. Twelve procedures out of 15 (12/15) achieved complete resolution of pleural fluid with a success rate of 80%. In two procedures the pleural effusion was reduced and then recurred but did not require re-aspiration. One procedure failed and repeated pleural aspiration was required. In this study, with adequate pleural drainage and the proper technique, vincristine was found to be an effective sclerosing agent for malignant pleural effusion. Further randomized trials are necessary in order to establish the role of this drug.
