RESUMO
AIMS AND OBJECTIVES: To evaluate the effectiveness of specialist nurse interventions in the care of women with breast cancer. BACKGROUND: Nurses perform a crucial role in physical and psychosocial support of women with breast cancer. However, only few reviews have explored and discussed the roles and interventions carried out by specialised nurses in breast cancer care. DESIGN: Systematic review based on PRISMA guidelines. METHODS: A comprehensive literature search was conducted in PubMed, CINAHL, Scopus, Web of Science, Science Direct, Cochrane Library, IndMed and Shodhganga databases for articles published in English language from 1980 to 2018. Only RCTs were included. Quality assessment, data extraction and analysis were completed on all included studies. RESULTS: Sixteen papers were assessed for methodological quality. Due to methodological heterogeneity of the papers, a meta-analysis was not performed. The reviewers categorised the main outcomes under different domains like physical problems, psychological problems, patient satisfaction, patient needs, quality of life and cost data. DISCUSSION: This review provides evidence on specialist nurses' role in breast cancer care. The methodological aspects of studies in this review vary in different aspects. More studies with rigorous scientific methods are needed to provide robust evidence on effectiveness of specialist nurses' role. CONCLUSION: Even though specialist nursing interventions can contribute to health outcomes of women with breast cancer, there is limited number of studies reported from developing countries. This warrants the need for specialist nurse interventions in breast cancer care from developing countries. RELEVANCE TO CLINICAL PRACTICE: Offering a specialist nurse service helps the patients to meet their informational and educational needs, supportive care and coordination of care. Specialist breast nurse services can be integrated into hospital setting to improve patient care and treatment adherence.

PURPOSE: Fatigue, decreased functionality, and impaired quality of life are some of the most common adverse outcomes of chemo-radiotherapy (CRT). Head and neck cancers (HNC) affect more than half a million individuals globally and its treatment takes a heavy toll on the patient, often affecting their speech, swallowing, and respiratory functions, and as a result they often develop fatigue, depression, and physical inactivity. The purpose of this study was to evaluate the effectiveness of exercise-based rehabilitation on functional capacity, quality of life, fatigue, hemoglobin, and platelet counts in patients with HNC on CRT. PATIENTS AND METHODS: A randomized controlled trial was conducted on 148 patients with head and neck cancer undergoing CRT to evaluate the effectiveness of exercise on functional capacity measured by the 6-min walk test, quality of life measured by the Medical Outcomes Survey Short Form 36 v2 questionnaire, fatigue by the NCCN (0-10) scale, hemoglobin, and platelets. The control group received standard physical activity recommendations while the exercise group received a structured exercise program of aerobic and active resistance exercises for a period of 11 weeks. RESULTS: There was a significant improvement in the functional capacity (p < 0.001), quality of life (p < 0.001), and prevention of worsening of fatigue (p < 0.001) in the exercise group. The blood parameters did not show a significant difference between the control group and the exercise group. CONCLUSION: Our results elucidate that an 11-week structured exercise program for HNC patients receiving CRT helps in improving their functional capacity and quality of life. It also prevents deterioration of fatigue levels in the exercise group.

AIM: The aim of this study was to report the patterns of recurrence, locoregional control, and survival of patients diagnosed with endometrial adenocarcinomas over a 7-year period after reclassifying them under the recent ESMO-ESGO-ESTRO (European Society of Medical Oncology/European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology) consensus classification. METHODS: Archives of a single institution from 2008 to 2014 were studied and patients with stages I-II endometrial adenocarcinoma were reclassified as per the new classification for uniformity. On magnetic resonance imaging, if found to be stage I, total abdominal hysterectomy with bilateral salpingo-oophorectomy alone was performed. The indications for adjuvant external beam radiotherapy (EBRT) and vaginal brachytherapy (VBT) were based on standard recommendations. Survival was calculated from Kaplan-Meier curves, and toxicity was recorded using Common Terminology Criteria for Adverse Events version 3. RESULTS: Of the 132 patients registered, 101 patients were included for analysis. A total of 18 patients have died, and information on outcome is available for 84% of patients. Five patients were metastatic at presentation. Five patients received definitive EBRT + intracavitary brachytherapy because of surgical inoperability, four of whom are disease-free locoregionally with median overall survival of 33.8 months. Of the 91 patients operated on, the incidence of low, intermediate, high-intermediate, and high risk was 34%, 29%, 2%, and 19%, whereas 16% were stage III. The overall recurrence rates were 10%, 15%, and 23% for low, intermediate, and high risk, respectively. With median follow-up of 32 months (range, 2-93 months), the disease-free survival for low, intermediate, and high risk and stage III were 92%, 81%, and 64% and 55%, whereas the mean survival for the same groups were 53, 44, and 34 and 22 months, respectively (P = 0.047). External beam radiotherapy resulted in significantly higher proctitis than VBT alone (P = 0.02). The median time to cystitis, proctitis, and enteritis were 27, 19, and 28 months, respectively. CONCLUSIONS: Recurrence rates, survival rates, and the patterns of recurrence are comparable with published literature and partly validates the ESMO-ESGO-ESTRO consensus statement. Addition of EBRT significantly increases risk of late proctitis as compared with VBT alone.

AIM: To evaluate the effectiveness of a Nurse Navigator Programme on anxiety, psychological distress and quality of life in people with breast cancer. BACKGROUND: Breast cancer is the most frequently detected malignancy and a major cause of cancer death among women around the world. The lengthy course of illness from initial diagnosis to treatment and subsequent follow-up causes deterioration in physical, psychological and social status among patients. Nurses have a major role in cancer care. As women with breast cancer have to undergo various treatment modalities, continued care by a pivot nurse is thought to enhance treatment adherence. Limited studies have been reported from developing countries on Nurse Navigation Programmes. DESIGN: A Stratified Randomized controlled trial with repeated measures. METHODS: One hundred and twenty newly diagnosed women with breast cancer admitted to surgery wards of a tertiary care hospital in South India will be recruited. (Project funded in Octo"ber 2014). Women are randomly allocated to a control and intervention group. The outcome variables are anxiety, psychological distress and quality of life. Data on outcome measures will be collected at five different time points: before surgery, at discharge, beginning of adjuvant therapy, middle of adjuvant therapy and at the end of adjuvant therapy. DISCUSSION: This study may give evidence on the effectiveness of a Nurse Navigator Programme for women with breast cancer. If significant effects were detected, the programme could be integrated into hospital services to improve the patient care.

PURPOSE: Chemoradiotherapy (CRT)-induced oral mucositis (OM) adversely affects a patient's oral functions and quality of life (QOL). Low-level laser therapy (LLLT) showed some preventive and curative effects against clinically reported objective measures of OM in few trials including our recently published study. There is dearth of evidence regarding the effects of LLLT on patient's subjective experience of OM and QOL. Hence, we did this study to evaluate the effects of LLLT on a patient's reported measures of OM and QOL in head and neck cancer (HNC) patients receiving CRT. METHODS: This triple blinded study randomized 220 HNC patients scheduled for CRT (three weekly Cisplatin + RT = 66 Gray (2 Gy/session), five fractions/week for 6.5 weeks, total 33 fractions) into laser (110) and placebo (110) groups. The laser group received LLLT (Technomed Electronics Advanced Laser Therapy 1000, He-Ne, λ = 632.8 nm, power density = 24 mW/cm(2), dosage = 3.0 J at each point, total dose/session = 36-40 J, spot size 1 cm(2), irradiation time/point 125 s) before each radiation session, while the placebo group did not receive laser therapy. Methodology was similar to our recently published study (Gautam et al. Radiother Oncol 104:349-354, 2012). In this part of our study, a blinded assessor collected subjective outcomes of the patient's reported measures of OM using Oral Mucositis Weekly Questionnaire-Head and Neck (OMWQ-HN) and QOL using Functional Assessment of Cancer Treatment-Head and Neck (FACT-HN) Questionnaire. Data were analyzed using repeated measure ANOVA through general linear model. Statistical significance was kept at p < 0.05. RESULTS: Results analysis revealed that OMWQ-HN (F = 12.199, df = 6,1314, p < 0.001) and FACT-HN (p < 0.05) scores were significantly lower in LLLT than placebo group patients. Also, a significant reduction (p < 0.001) in incidence of severe OM, need for opioid analgesics, and total parenteral nutrition was observed. CONCLUSIONS: LLLT was effective in improving the patient's subjective experience of OM and QOL in HNC patients receiving CRT.

BACKGROUND: The dedicated devices for blood irradiation are available only at a few centers in developing countries thus the irradiation remains a service with limited availability due to prohibitive cost. OBJECTIVE: To implement a blood irradiation program at our center using linear accelerator. MATERIALS AND METHODS: The study is performed detailing the specific operational and quality assurance measures employed in providing a blood component-irradiation service at tertiary care hospital. X-rays generated from linear accelerator were used to irradiate the blood components. To facilitate and standardize the blood component irradiation, a blood irradiator box was designed and fabricated in acrylic. Using Elekta Precise Linear Accelerator, a dose of 25 Gy was delivered at the centre of the irradiation box. Standardization was done using five units of blood obtained from healthy voluntary blood donors. Each unit was divided to two parts. One aliquot was subjected to irradiation. Biochemical and hematological parameters were analyzed on various days of storage. Cost incurred was analyzed. RESULTS: Progressive increase in plasma hemoglobin, potassium and lactate dehydrogenase was noted in the irradiated units but all the parameters were within the acceptable range indicating the suitability of the product for transfusion. The irradiation process was completed in less than 30 min. Validation of the radiation dose done using TLD showed less than ± 3% variation. CONCLUSION: This study shows that that the blood component irradiation is within the scope of most of the hospitals in developing countries even in the absence of dedicated blood irradiators at affordable cost.

OBJECTIVES: To document the dose received by brachial plexus (BP) in patients treated with intensity-modulated radiotherapy (IMRT) for head-and-neck squamous cell carcinoma (HNSCC) and report the incidence of brachial plexopathy. METHODS: Newly diagnosed patients of HNSCC treated with radical or adjuvant IMRT were included in this retrospective study. No dosimetric constraints were applied for BP maximum dose equivalent dose (EQD2 α/ß = 3). Patients with minimum 6-month follow-up were included and patients with suspicion of plexopathy were evaluated further. RESULTS: Sixty-seven patients were eligible and 127 BP were analyzed. The mean BP maximum dose (BPmax) was 62.4 Gy (+6.9), while mean BP volume was 28.1 cc (+4.1). Proportion of patients receiving BPmax >66 and >70 Gy were 34.7% and 14.2%. The mean BPmax for T4 tumors was significantly higher than T1 tumors (65 vs. 57.5 Gy, P = 0.005) but when adjusted for N-category, T-category was not independently significant in accounting for BPmax >66 or >70 Gy. Mean BPmax for N0 versus N2+ was 59.8 versus 65.6 Gy (P = 0.0001) and N1 versus N2+ was 61.6 versus 65.6 Gy (P = 0.018). After adjusting for T-category, patients with N2+ had a mean 4.2 Gy higher BPmax than N0-N1 (P = 0.0001). Stage III-IV patients had a mean six Gy higher BPmax doses than Stage I-II disease (P = 0.0001). With a median follow-up of 28 months (interquartile range 16-42), no patient had brachial plexopathy. CONCLUSION: Clinically significant plexopathy was not seen in spite of majority having over 2-years follow-up and a third of patients having dose above the recommended tolerance. Only nodal category independently influenced dose to the brachial plexii.

Although metastasis to the eye is the most common ophthalmic malignancy, it is usually asymptomatic and rarely a presenting symptom that leads to the diagnosis of a primary. Here, we report a patient who was evaluated for visual symptoms and was eventually diagnosed to have disseminated adenocarcinoma of the lung. He was treated with external radiotherapy to the choroidal metastasis, attaining an excellent response that was sustained until his death. A brief review on the role of radiotherapy in the management of uveal metastases is also presented.

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.

OBJECTIVE: A study was conducted to develop and validate a screening model using risk scores to identify individuals at high risk for developing oral cancer in an Indian population. METHODS: Life-course data collected from a multicentre case-control study in India were used. Interview was conducted to collect information on predictors limited to the time before the onset of symptoms or cancer diagnosis. Predictors included statistically significant risk factors in the multivariable model. A risk score for each predictor was derived from respective odds ratios (OR). Discrimination of the final model, risk scores and various risk score cut-offs was examined using the c statistic. The optimal cut-off was determined as the one with good area under curve (AUC) and high sensitivity. Predictive ability of the regression model and cut-off risk score was determined by calculating sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Models were validated from a bootstrap sample. RESULTS: Smoking, chewing quid and/or tobacco, alcohol, a family history of upper aero-digestive tract cancer, diet and oral hygiene behaviour were the predictors. Risk scores ranged from 0 to 28. Area under the receiver operating characteristic (ROC) curve for risk scores was good (0.866). The sensitivity (0.928) and negative predictive value (0.927) were high, while specificity (0.603) and positive predictive value (0.607) were low for a risk score cut-off of 6. CONCLUSION: A risk score model to screen for individuals with high risk of oral cancer with satisfactory predictive ability was developed in the Indian population. Validation of the model in other populations is necessary before it can be recommended to identify subgroups of the population to be directed towards more extensive clinical evaluation.

OBJECTIVES: Radiotherapy (RT) is treatment of choice for Elderly Head and Neck Cancer (HNC) patients. Oral mucositis (OM) during RT affects patient's routine oral activities and overall health. Low Level Laser Therapy (LLLT) provided some promising results against cancer therapy induced OM in children and adults. No study specifically evaluated effects of LLLT against RT induced OM in elderly HNC patients until date, hence we did this study. MATERIAL AND METHODS: This double blinded study randomized 46 elderly HNC patients scheduled for RT [Dosage=66 Gray (2 Gy/fraction), 5 fractions/week, total 33 fractions for 6.5 weeks], into laser (22) and placebo (24) groups. Laser group patients received LLLT [Helium-Neon, λ=632.8 nm, power density=0.024 W/cm(2), dosage=3.0 J/point at six anatomical sites bilaterally i.e. 12 locations, total dose/session=36 J, beam aperture diameter=0.6 mm, beam spot size=1 cm(2), irradiated area diameter=1 cm(2), irradiation time/point=125 s, 5 sessions/week, non-contact method-distance between probe and irradiated tissues <1 cm, whereas placebo group did not receive laser. OM grades (RTOG/EORTC Scale), oral pain, weight loss, need for morphine analgesics and tube feeding, and RT break were recorded by a blinded assessor. Descriptive statistics and repeated measures ANOVA were used for analysis keeping p<0.05. RESULTS: Significant reduction in the incidence and duration of severe OM (p=0.016) and severe pain (p=0.023) and weight loss (p=0.004) was observed in laser than placebo group. No difference was found for enteral feeding use (p=0.667) between two groups. CONCLUSIONS: LLLT decreased the severity of OM and oral pain in elderly HNC patients. Also, lesser weight loss, morphine analgesic use and radiation break happened in laser group.

Existing literature suggests that cancer survivors present with high rates of morbidity due to various treatment and disease induced factors. Research globally has shown exercise to be beneficial in improving treatment outcomes and quality of life. India has a high prevalence of cancer and not much is known about exercise interventions for cancer survivors in India. This review was planned to review the state of exercise based interventions for cancer survivors in India. A comprehensive literature search was performed in PubMed, CINAHL, EMBASE, Scopus, Cochrane Library, PEDro, IndMed, and Shoda Ganga. The search results were screened and data extracted by two independent reviewers. All eligible studies were assessed for methodological quality rating using Downs and Black checklist. Data was extracted using a pilot tested pro forma to summarize information on site and stage of cancer, type of exercise intervention and outcome measures. The review identified 13 studies, published from 1991 to 2013, after screening 4060 articles. Exercise interventions fell into one of three categories: (1) yoga-based, (2) physiotherapy-based and (3) speech therapy based interventions; and exclusively involved either breast or head and neck cancers. Studies were generally of low to moderate quality. A broad range of outcomes were found including symptoms, speech and swallowing, and quality of life and largely supported the benefits of exercise-based interventions. At present, research involving exercise-based rehabilitation interventions in India is limited in volume, quality and scope. With the growing burden of cancer in the country, there is an immediate need for research on exercise based interventions for cancer survivors within the sociocultural context of India.
RESUMO
Vitiligo is a common depigmentation disorder of skin, etiology of which is poorly understood. It has been rarely reported as a consequence of radiation at the site of irradiation, more so in patients with prior history of vitiligo. We report a rare clinical vignette that documents radiation-induced skin depigmentation, which started at the irradiated site and later manifested as generalized vitiligo, in a breast cancer patient with no family history of vitiligo. Studies describing the relationship between skin depigmentation and radiotherapeutic dose are scanty. The possible etiopathological mechanisms of vitiligo and radiation as a potential triggering factor for its development, which has been described in the literature, have been highlighted in this article.

CONTEXT: Patients diagnosed with a cancer have a life time risk of developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. Of late the detection of new primary has increased mainly due to refinement in both diagnostic and treatment modalities. Cancer victims are surviving longer and thus are more likely to develop a new metachronous malignancy. AIMS: To report our observed trend of increase in prevalence of both synchronous and metachronous second malignant neoplasms among cancer victims and to review the relevant literature. SETTINGS AND DESIGN: A hospital based retrospective collection of prospective data of patients diagnosed with second denovo malignancy. MATERIALS AND METHOD: The study was conducted over a 5 year period from July 2008 to June 2012. All patients diagnosed with a histologically proven second malignancy as per Warren Gate's criteria were included. Various details regarding sex, age at presentation, synchronous or metachronous, treatment and outcome were recorded. CONCLUSIONS: The occurrence of multiple primary malignancies is not rare. Awareness of the possibility alerts the clinician in evaluation of patients with a known malignancy presenting with unusual sites of metastasis. Individualizing the treatment according to the stages of the primaries will result in durable cancer control particularly in synchronous double malignancy.

BACKGROUND: Patients receiving chemoradiotherapy (CRT) for oral cancer (OC) often develop oral mucositis (OM). OM associated pain severely affects oral functions and nutrition of the patient, resulting in narcotic analgesic use and CRT interruption. Laser therapy has shown some promising results in preventing and treating OM caused by cancer therapies. So in this trial we used prophylactic Low Level Helium Neon (He-Ne) Laser for the prevention and treatment of CRT induced OM in OC patients. MATERIALS AND METHODS: This double blinded trial block randomized 121 primary OC patients scheduled to undergo CRT [RT dosage=66 Gray/33 fractions for 5 days/week and chemotherapy (3 weekly Cisplatin)] into laser (n=60) and placebo (n=61) group. Laser group received He-Ne Laser (λ=632.8 nm, P=24 mW, ED=3.5 J/cm(2)) while placebo received sham treatment just before radiation for 6.5 weeks. OM (RTOG/EORTC Scale), its associated pain, and total parenteral nutrition (TPN), were assessed on every week by a blinded assessor. Also opioid analgesic use, weight loss and any CRT break were recorded. Data was analyzed using descriptive statistics, t-test and Man Whitney U test. Level of significance was set at p<0.05. RESULTS: Incidence of severe OM (29% vs. 89%, p<0.001) and its associated pain (18% vs. 71%, p<0.001), opioid analgesic use (7% vs. 21%, p<0.001)and TPN (30% vs. 39% p=0.039) was significantly less in laser than placebo group patients. Also duration of severe OM and pain experienced was less in laser than placebo group. CRT break required only for placebo group (9%) patients. CONCLUSION: Low Level He-Ne Laser decreased the incidence of CRT induced severe OM and its associated pain, opioid analgesics use and TPN.

BACKGROUND AND PURPOSE: Oral mucositis (OM) is most cumbersome acute side effect of concurrent chemoradiotherapy (CCRT) for head and neck cancer (HNC). OM associated pain affects oral functions and nutrition of the patient that may result in discontinuity of treatment. Several modalities have been tried to prevent and treat OM, but none proved completely successful until date. We used prophylactic low level laser therapy (LLLT) for the prevention and treatment of CCRT induced OM. MATERIALS AND METHODS: In this triple blinded study, 221 HNC patients scheduled to undergo CCRT (Cisplatin (1, 22, 43 day)+RT=66 Grays (2 Gy/fraction), 33 fractions, 5 fractions/week, for 45 days) were block randomized into laser (n=111) and placebo (n=110) group. Laser group received LLLT (HeNe, λ=632.8 nm, power-density=24 mW, dosage=3.0 J/point, total dosage/session=36-40 J, spot-size=1cm(2), 5 sessions/week) while placebo received sham treatment daily prior to radiation. OM (RTOG/EORTC Scale), oral pain (VAS), dysphagia (FIS), weight loss and CCRT break were assessed. Data were analyzed using frequencies and percentage, generalized estimating equations (GEE) and odds ratio. RESULTS: There was significant reduction in incidence of severe OM (F=16.64, df=8876, p<0.0001) and its associated pain (F=25.06, df=8876, p<0.0001), dysphagia (F=20.17, df=8876, p<0.0001) and opioid analgesics use (p<0.0001) in laser than placebo group patients. CONCLUSIONS: LLLT decreased the incidence of CCRT induced severe OM and its associated pain, dysphagia and opioid analgesics use.

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.

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.
