Breast cancer treatment and its impact on survival in Morocco: a study over a decade.

BACKGROUND: In Morocco, much progress has been made in breast cancer treatment. However, there is limited information on survival outcomes of breast cancer patients according to their therapeutic management. METHODS: A pattern-of-care study was conducted in Morocco's two main oncology centres: Rabat and Casablanca and has shown that major progress has been made in the quality of care with survival rates comparable to those in developed countries. The present study focuses on the different therapeutic strategies used in breast cancer and their impact on prognosis. Patients were classified into two categories: those considered as appropriately managed and those who were not. RESULTS: A total of 1901 women with stage I to III breast cancer were included in this study, the majority (53%) were adequately managed and had better disease-free survival (DFS) rates than those who were not: DFS at 3 years (88% versus 62%) and at 5 years (80% versus 50%). Potential significant determinants of better management were: treatment in Rabat's oncology centre, treatment between 2008 and 2012, being aged younger than 60 years, and early TN stage. CONCLUSION: This study demonstrated the value of proper integrated and coordinated management in a comprehensive cancer centre, to improve breast cancer survival.

Lessons Learnt From Pilot Cervical Cancer Screening and Treatment Programmes Integrated to Routine Primary Health Care Services in Benin, Cote d'Ivoire, and Senegal.

PURPOSE: The project aimed to implement pilot screening and treatment services for cervical cancer integrated with existing primary health centers (PHCs) in Benin, Cote d'Ivoire, and Senegal and evaluate these services using implementation research outcomes such as reach, effectiveness, adoption, and acceptability. MATERIALS AND METHODS: The Ministry of Health in each country took the lead in setting up a stakeholder's group that designed a protocol tailored to the local context. The target age was 25-49 years in Benin and Cote d'Ivoire and 30-49 years in Senegal. Visual inspection with acetic acid (VIA) was the screening test, and thermal ablation (TA) was the ablative treatment of choice in all. The Ministry in each country identified 4-5 PHCs to set up screening and ablation services and one higher-level center for colposcopy referral. After a master-trainer led training program, nurses, midwives, or general practitioners screened opportunistically the eligible women attending the clinics. The VIA-positive women eligible for ablation were offered immediate treatment. RESULTS: Between May 2018 and January 2021, 16,530 women were screened opportunistically. VIA positivity was 8.1% with huge variability within and between countries. Sixty-one percent of all VIA-positive cases were eligible for immediate TA, and 88% of them accepted same-day treatment. Compliance to TA at PHCs was 99%. Majority of women treated with TA complained of minor side effects. Significant dropouts occurred as the women were referred to colposcopy clinics. CONCLUSION: Opportunistic screening provided as part of routine PHC service can screen many women and treat a significant proportion of screen-positive women with TA with minimal side effects. Primary concerns are the hard-to-reach women who remain out of opportunistic screening coverage and noncompliance of the screen-positive women referred to higher-level centers.

Evolution of patterns of care for women with cervical cancer in Morocco over a decade.

BACKGROUND: We conducted a Pattern-of-care (POC) study at two premier-most public-funded oncology centers in Morocco to evaluate delays in care continuum and adherence to internationally accepted treatment guidelines of cervical cancer. METHOD: Following a systematic sampling method, cervical cancer patients registered at Centre Mohammed VI (Casablanca) and Institut National d'Oncologie (Rabat) during 2 months of every year from 2008 to 2017, were included in this retrospective study. Relevant information was abstracted from the medical records. RESULTS: A total of 886 patients was included in the analysis; 59.5% were at stage I/II. No appreciable change in stage distribution was observed over time. Median access and treatment delays were 5.0 months and 2.3 months, respectively without any significant temporal change. Concurrent chemotherapy was administered to 57.7% of the patients receiving radiotherapy. Surgery was performed on 81.2 and 34.8% of stage I and II patients, respectively. A very high proportion (85.7%) of operated patients received post-operative radiation therapy. Median interval between surgery and initiation of radiotherapy was 3.1 months. Only 45.3% of the patients treated with external beam radiation received brachytherapy. Radiotherapy was completed within 10 weeks in 77.4% patients. An overall 5-year disease-free survival (DFS) was observed in 57.5% of the patients - ranging from 66.1% for stage I to 31.1% for stage IV. Addition of brachytherapy to radiation significantly improved survival at all stages. The study has the usual limitations of retrospective record-based studies, which is data incompleteness. CONCLUSION: Delays in care continuum need to be further reduced. Increased use of chemoradiation and brachytherapy will improve survival further.

Delivering colorectal cancer screening integrated with primary health care services in Morocco: Lessons learned from a demonstration project.

BACKGROUND: Colorectal cancer (CRC) incidence and mortality rates are increasing rapidly in many low-income and middle-income countries. A demonstration project was implemented in Morocco in collaboration with the Ministry of Health to assess the feasibility, acceptability, and challenges of implementing CRC screening through routine primary care facilities. METHODS: The objective of the project was to screen 10,000 men and women aged 50 to 75 years through 10 primary health centers (PHCs) in 2 provinces. All eligible men and women attending the selected PHCs were offered the fecal immunochemical test (FIT). Stool specimens brought to the PHCs were tested immediately by trained nurses. FIT-positive individuals were referred to the National Oncology Institute for colonoscopy. RESULTS: In total, 9763 eligible men and women were screened by FIT between June 2017 and May 2019; most (73.3%) were women. The test was positive in 460 participants (4.7%). Among the individuals who had positive FIT results, 62.6% underwent colonoscopy. The main reasons for noncompliance to colonoscopy were competing life priorities (15.4%), other health problems (13%), and fear of getting a cancer diagnosis (12.3%). As the number of referrals to colonoscopy increased, the waiting time for the procedure increased, resulting in a drop in compliance. The detection rates of advanced adenomas and CRC were 4.0 in 1000 and 0.5 in 1000 individuals screened, respectively. CONCLUSIONS: An effective strategy to reach the target populations (especially men), a pragmatic assessment of the health system's capacity to deal with large numbers of referrals, and a formal cost-effectiveness analysis are essential before making any decision to introduce CRC screening in Morocco.

The Impact of Socioeconomic Determinants on the Quality of Life of Moroccan Breast Cancer Survivors Diagnosed Two Years Earlier at the National Institute of Oncology in Rabat.

INTRODUCTION: The objective of this study was to investigate the impact of socioeconomic determinants on the quality of life of Moroccan women with breast cancer two years after their diagnosis who are followed up at the National Institute of Oncology (INO) in Rabat. METHODS: This is a cross-sectional study that was conducted between May 2019 and September 2020. The sample size was 304 women. Data were collected using the EORTC QLQ-C30 and EORTC QLQ-BR 23 questionnaires in the Moroccan dialect. RESULTS: The mean age of participants was 53.5 ± 12.4 years, where the majority resided in urban areas and more than half were illiterate. Moreover, three-quarters of the survivors were not working, and almost all have basic medical coverage. Nearly one-third of the respondents had experienced discrimination from those around them, and nearly half attributed the decrease in income to their state of health. In addition, 38.2 percent of participants stated that they had great difficulty living on their monthly income after the illness, whereas more than half of the survivors had a good quality of life in terms of overall health (GHS/QOL). Besides, social function obtained the highest score, while emotional function obtained the lowest score. Furthermore, financial difficulty was the most distressing symptom. Indeed, income adjustment after the disease, discrimination, distance between home and treatment center, professional status, and medical coverage were correlated with GHS/QOL. Regression analysis revealed that income adjustment after illness and discrimination were significant predictors of GHS/QOL. CONCLUSION: The data suggest establishing a financial support program and the development of education and awareness-raising policies to combat discrimination.

Patterns of care of breast cancer patients in Morocco - A study of variations in patient profile, tumour characteristics and standard of care over a decade.

Guided by a national cancer plan (2010-19), Morocco made significant investments in improving breast cancer detection and treatment. A breast cancer pattern-of-care study was conducted to document the socio-demographic profiles of patients and tumour characteristics, measure delays in care, and assess the status of dissemination and impact of state-of-the-art management. The retrospective study conducted among 2120 breast cancer patients registered during 2008-17 at the two premier-most oncology centres (Centre Mohammed VI or CM-VI and Institut National d'Oncologie or INO) also measured temporal trends of the different variables. Median age (49 years) and other socio-demographic characteristics of the patients remained constant over time. A significant improvement in coverage of the state-financed health insurance scheme for indigent populations was observed over time. Median interval between onset of symptoms and first medical consultation was 6 months with a significant reduction over time. Information on staging and molecular profile were available for more than 90% and 80% of the patients respectively. Approximately 55% of the patients presented at stage I/II and proportion of triple-negative cancers was 16%; neither showing any appreciable temporal variation. Treatment information was available for more than 90% of the patients; 69% received surgery with chemotherapy and/or radiation. Treatment was tailored to stage and molecular profiles, though breast conservation therapy was offered to less than one-fifth. When compared using the EUSOMA quality indicators for breast cancer management, INO performed better than CM-VI. This was reflected in nearly 25% difference in 5-year disease-free survival for early-stage cancers between the centres.

The Care Pathway Delays of Cervical Cancer Patient in Morocco.

INTRODUCTION: The aim of this study is to document time intervals in cervical cancer care pathways, from symptom onset to disease detection and start of treatment, and evaluate how clinical, sociodemographic, and treatment factors influence delays throughout a patient's clinical pathway. METHODS: A retrospective study was conducted at the FEZ Oncology Hospital of the Hassan II University Hospital Center in Morocco. RESULTS: 190 medical records of cervical cancer patients were collected. The dominant age group was 35-44, the median patient delay (PD) was 6 days, the median healthcare provider's delay (HCP) was 21 days, the median referral delay (RD) was 17 days, the median diagnostic delay (DD) was 9.5 days, the median total diagnostic delay (TDD) was 16 days, the median treatment delay (TD) was 67 days, and the median health system interval (HSI) was 92 days. Multivariate analysis revealed that age was associated with the patient delay, the healthcare provider's delay, the diagnosis delay, and the health system interval. The diagnosis year (the year in which the patient was diagnosed (either before 2012 or during 2012 as well as the other study years (from 2013 to 2017))), all investigations done prior to admission to the oncology hospital, and the age of first sexual activity were significantly associated with healthcare provider's delay. CONCLUSION: The integration of a model and standard care pathway into the Moroccan health system is essential in order to unify cervical cancer care in the country.

Tackling cancer burden in low-income and middle-income countries: Morocco as an exemplar.

Examples of successful implementations of national cancer control plans in low-income or middle-income countries remain rare. Morocco, a country where cancer is already the second leading cause of death after cardiovascular diseases, is one exception in this regard. Population ageing and lifestyle changes are the major drivers that are further increasing the cancer burden in the country. Facing this challenge, the Moroccan Ministry of Health has developed a we l planned and pragmatic National Plan for Cancer Prevention and Control (NPCPC) that, since 2010, has been implemented with government financial support to provide basic cancer care services across the entire range of cancer control. Several features of the development and implementation of the NPCPC and health-care financing in Morocco provide exemplars for other low-income and middle-income countries to follow. Additionally, from the first 5 years of NPCPC, several areas were shown to require further focus through implementation research, notably in strengthening cancer awareness, risk reduction, and the referral pathways for prevention, early detection, treatment, and follow-up care. Working together with a wide range of stakeholders, and engagement with stakeholders outside the health-care system on a more holistic approach can provide further opportunities for the national authorities to build on their successes and realise the full potential of present and future cancer control efforts in Morocco.

Factors Associated with Delayed Diagnosis of Lymphomas: Experience with Patients from Hematology Centers in Morocco

Background: Moroccan cancer patients usually have to go through several steps before they are diagnosed. It is important to assess factors associated with diagnosis delay for lymphomas, which might have significant effects on survival. The aim of this study was to determine factors leading to late diagnosis of lymphomas. Methods: A cross-sectional study was conducted with three hematology centers in Morocco in 2008, to analyze the impact of sociodemographic and clinical factors on delay-time from symptoms to diagnosis. Results: A total of 151 patients were included in the study. Late delay was significantly associated with gender, (for men compared to women: OR=2.46; 95% CI: 1.06-5.74), to marital status (not married: OR=2.50; 95% CI: 1.06-5.92) and low socioeconomic level (OR=5.82; 95% CI: 2.23-15.17). Late medical delay was significantly associated with having three or more medical visits before diagnosis (Adjusted OR=5.67; 95% CI: 2.55-12.59). Late total delay was observed for patients with three children or less (adjusted OR=4.39; 95% CI: 1.32-14.56), those who were non-married (adjusted OR=2.49; 95% CI: 1.07-5.81), had a non Hodgkin's lymphoma (Adjusted OR=2.08; 95% CI: 1.06-4.00) or featuring three or more medical visits before the diagnosis (Adjusted OR=2.13; 95% CI: 0.99-5.88). Conclusion: This analysis provides a basis for understanding the sources, extent, and root causes of lymphoma diagnostic delays. The findings appear crucial for system-wide interventions aimed to facilitate clinical management of patients with lymphoma and to improve prognosis and quality of life.

Validation of EORTC IN-PATSAT 32 in Morocco: Methods and Processes

Background. The EORTC IN-PATSAT32 questionnaire was developed by the EORTC Quality of Life (QL) Group to assess the satisfaction of patients affected by cancer and hospitalized in oncology centers. The aim of this study is to assess the psychometric properties of the EORTC IN-PATSAT32 administered to Moroccan patients. Methods. A total of 133 hospitalized patients affected by cancer in different sites completed the translated EORTC IN-PATSAT32 questionnaire in oncology hospitals. The internal consistence reliability, reproducibility and construct validity were assessed. Results. The homogeneity was good for all scales with Cronbach's coefficients from 0.72 to 0.95 for all scales. Reproducibility test-retest was very satisfactory and the intra-class correlations coefficients (ICCs) for the scales were all above 0.70 except for the single general satisfaction with a ICC of 0.67. All items were highly correlated with own rather than other scales. Conclusion. The results of this study confirm that the Moroccan Arabic version of the EORTC IN-PATSAT32 has acceptable reliability and validity, comparable to those reported for other languages.

Knowledge, Attitudes, and Preventive Practice Towards Breast Cancer among General Practitioner Health Professionals in Morocco

Background: Breast cancer is the most common cancer of women in Morocco and its diagnosis is usually made at advanced stages. The aim of this study was to describe the knowledge, practices and attitudes of general practitioners regarding early detection of breast cancer. Methods: A cross-sectional study was carried out during July 2011 on a sample of 140 general practitioners employed in basic health care facilities. Results: The majority (85.7%) of general practitioners were aware of the existence of a ministerial circular which aimed to generalize breast cancer screening. Systematic practice of clinical breast examination was reported by 18.0% of doctors for every woman between 45 and 70 years and a systematic breast self-examination check-up was reported by 59.4% of physicians. Mammography was requested by 54.1% of physicians in the presence of risk factors. Females and physicians practicing in urban areas were less likely to have a knowledge, attitudes and practices score higher than 8 as compared to male physicians and those practicing in rural areas. Discussion and conclusion: Our study showed that the knowledge, attitudes and practices of general practitioners regarding the early detection of breast cancer program were not satisfactory; hence the urgent need for improved implementation of the program in the affected regions.

Determinants of Patient Delay in Seeking Diagnosis and Treatment among Moroccan Women with Cervical Cancer.

Introduction. This study sought to investigate potential determinants of patient delay among Moroccan women with cervical cancer. Methods. A cross-sectional study was conducted from June 2014 to June 2015 at the National Institute of Oncology in Rabat. Data were collected using questionnaire among patients with cervical cancer locally advanced or metastatic (stages IIA-IVB). Medical records were abstracted to complete clinical information. An interval longer than 90 days between discovery of initial symptoms and presentation to a provider was defined as a patient delay. Results. Four hundred and one patients with cervical cancer enrolled in this study. The mean age was 52.4 years (SD = 11.5). 53.6% were illiterate. Abnormal vaginal bleeding was identified for 65.8% of patients. 60.1% were diagnosed at stages IIA-IIB. 55.4% were found having patient delay. The regression analyses showed the association between literacy (p < 0.001), distance of the place of the first consultation (p = 0.031), abnormal vaginal bleeding as an earlier symptom (p < 0.001), stage at diagnosis (p < 0.03), knowledge of symptoms (p < 0.001), knowledge of causes (p = 0.008), and practice of gynecological exam during the last three years (p = 0.018) and the patient delay. Conclusion. Educational messages should aim at increasing awareness of cervical cancer, assisting women in symptom recognition, and encouraging earlier presentation.

Quality of life of early stage colorectal cancer patients in Morocco.

BACKGROUND: A multicentre cohort study was held in Morocco, designed to evaluate the quality of life of cancer patients. The aim of this paper is to report the assessment of the quality of life of early colorectal cancer patients, before and after cancer treatment, to identify other factors which are related to this quality of life. METHODS: We used the third version of the QLQ-C30 questionnaire of the European organization for Research and treatment of Cancer (EORTC) after a transcultural validation. The Data collection was done at inclusion and then every twelve weeks to achieve one year of follow up. RESULTS: Overall 294 patients presented with early colorectal cancer, the median age was 56 years (range: 21-88). The male-female sex ratio was 1.17. At inclusion, the global health status was the most affected functional dimension. For symptoms: financial difficulties and fatigue scores were the highest ones. Emotional and social functions were significantly worse in rectal cancer. Most symptoms were more present in rectal cancer. At inclusion, global health status score was significantly worse in stage III. Anorexia was significantly more important among colorectal female patients. For Patients over 70 years-old, the difference was statistically significant for the physical function item which was lower. Overall, Functional dimensions scores were improved after chemotherapy. The symptoms scores did not differ significantly for patients treated by radiotherapy, between inclusion and at one year. CONCLUSION: Our EORTC QLQ C30 scores are overall comparable to the reference values. Neither chemotherapy, nor radiotherapy worsened the quality of life at one year.

Quality of life in Arab women with breast cancer: a review of the literature.

BACKGROUND: Quality of life has become an important concept in cancer care. Among the quality of lifestudies in cancer patients, breast cancer has received most attention. This review reports on quality of life in Arab patients with breast cancer. METHODS: The search was conducted using inclusion and exclusion criteria and in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The databases consulted were PubMed, Sciences Direct, Index Medicus for Wordl Health Organization Eastern Mediterranean, African Journals Online and African Index Medicus. RESULTS: Thirteen articles from eight countries met the inclusion criteria. The EORTC quality of life questionnaires (QLQ-C30 and QLQ-BR23) were the most used instrument (7 out of 13). The results showed that good scores of global health were recorded at Arab women living in United Arab Emirates (mean score = 74.6) compared to other countries. The results indicated that there was a difference in quality of life scores and its associated factors among Arab women with breast cancer. CONCLUSION: This paper is the first that reviewed published research on quality of life among Arab women with breast cancer. We found that insufficient results-related information is available.

Health-Related Quality of Life among Breast Cancer Patients and Influencing Factors in Morocco

Background: Breast cancer is the most common cancer among women in most countries of the world. It is ranked first in females in Morocco (accounting for 33.4% of the total cancer burden) and more than 60% of cases are diagnosed at stage III or IV. During the last decade, health-related quality of life (HRQOL) has become an important aspect of breast cancer treatment. The objective of this study was to describe self-reported HRQOL in patients with breast cancer and to investigate its associations with sociodemographic and clinical variables. Methods: A prospective study was carried out in the main oncology centers in Morocco. Quality of life was measured using the Moroccan Arabic versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C 30 (EORTC QLQ C30) and the Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). Statistical analyses were performed using descriptive statistics and multivariate analyses. Results: A total of 1463 subjects were included in the study, with a mean age of 55.6 (SD. 11.2) years, 70% being married. The majority had stage II (45.9%) and a few cases stage IV (12.9%) lesions. The participants' global health mean score was 68.5 and in "functional scales", social functioning scored the highest (Mean 86.2 (SD=22.7)). The most distressing symptom on the symptom scale was financial difficulties (Mean 63.2 (SD=38.2)). Using the disease specific tool, it was found that future perspective scored the lowest (Mean 40.5 (SD=37.3)). On the symptom scale, arm symptoms scored the highest (Mean 23.6 (SD=21.6)). Significant mean differences were noted for many functional and symptom scales. Conclusion: Our results emphasized that the general HRQOL for our study population is lower than for corresponding populations in other countries. This study provided baseline information on the quality of life for a large sample of Moroccan women diagnosed with breast cancer.

Breast Cancer Screening in Morocco: Performance Indicators During Two Years of an Organized Programme.

BACKGROUND: Breast cancer is commonly diagnosed at late stages in countries with limited resources. In Morocco, breast cancer is ranked the first female cancer (36.1%) and screening methods could reduce the proportion presenting with a late diagnosis. Morocco is currently adopting a breast cancer screening program based on clinical examination at primary health facilities, diagnosis at secondary level and treatment at tertiary level. So far, there is no systematic information on the performance of the screening program for breast cancer in Morocco. The aim of this study was to analyze early performance indicators. MATERIALS AND METHODS: A retrospective evaluative study conducted in Temara city. The target population was the entire female population aged between 45-70 years. The study was based on process and performance indicators collected at the individual level from the various health structures in Tamara between 2009 and 2011. RESULTS: A total of 2,350 women participated in the screening program; the participation rate was 35.7%. Of these, 76.8% (1,806) were married and 5.2% (106) of this group had a family history of breast cancer. Of the women who attended screening, 9.3% (190) were found to have an abnormal physical examination findings. A total of 260 (12.7%) were referred for a specialist consultation. The positive predictive value of clinical breast examination versus mammography was 23.0%. Forty four (35.5%) of the lesions found on the mammograms were classified as BI-RADs 3; 4 or 5 category. Cancer was found in 4 (1.95%) of the total number of screened women and benign cases represented 0.58%. CONCLUSIONS: These first results of the programme are very encouraging, but there is a need to closely monitor performance and to improve programme procedures with the aim of increasing both the participation rate and the proportion of women eligible to attend screening.

Public awareness of cancer risk factors in the Moroccan population: a population-based cross-sectional study.

BACKGROUND: In Morocco, knowledge of cancer risk factors, a crucial element in the process of behavioral change, has never been evaluated. This study aims to provide information on the level of awareness of cancer risk factors among the Moroccan general population. METHODS: A cross sectional survey was carried out in May 2008, using a stratified sampling method in a representative sample of the Moroccan adult population. The used questionnaire included social and demographic data as well as questions about 14 cancer related factors regarding passive or active smoking, alcoholic beverages, obesity, physical inactivity, food coloring, red meat, fat, salt, fruit, vegetables, olive oil, green tea, coffee, breast-feeding. Subjects had to choose between 3 propositions for each proposed factor (risk factor/Protective factor/Don't Know). The knowledge score was calculated by summing the correct answer for each proposed factor except coffee and food coloring. The answer was assigned 1 if it's correct or 0 if it was incorrect or the participant responded 'don't know. The maximum knowledge score was 12. Multivariate linear regression model was used to evaluate the determinants of knowledge score. RESULTS: Among 2891 subjects who participated to the survey, 49.5% were men and 42% were from a rural area. The mean age was 41.6 ± 15.2 years. The mean knowledge score of cancer related factors was 8.45 ± 3.10 points. Knowledge score increased with educational level (ß = -0.65 if school year ≤6 versus >6) and housing category (ß = 1.80 in high standing housing vs rural housing). It was also higher in urban area, among never smokers and among people never consuming alcohol compared to others groups. CONCLUSION: These results provide valuable information necessary to establish relevant cancer prevention strategies in Morocco aiming to enhance and improve people's knowledge about risk factors especially in some target groups.

Translation and validation of European organization for research and treatment of cancer quality of life Questionnaire -C30 into Moroccan version for cancer patients in Morocco.

BACKGROUND: Understanding the effects of cancer on the quality of life of affected patients is critical to clinical research as well as to optimal management and care. The aim of this study was to adapt the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) questionnaire into Moroccan Arabic and to determine its psychometric properties. After translation, back translation and pretesting of the pre-final version, the translated version was submitted to a committee of professionals composed by oncologists and epidemiologists. The psychometric properties were tested in patients with cancer. Internal consistency was tested using Cronbach's alpha and the test-retest reliability using interclass correlation coefficients. Construct validity was assessed by examining item-convergent and divergent validity. It was also tested using Spearman's correlation between QLQ-C30 scales and EQ-5D. RESULTS: The study was conducted in 125 patients. The Moroccan version was internally reliable, Cronbach's α was 0.87 for the total scale and ranged from 0.34 to 0.97 for the subscales. The intraclass correlation coefficient of the test-retest reliability ranged from 0.64 for "social functioning" to 0.89 for "physical activities" subscales. The instrument demonstrated a good construct and concomitant validity. CONCLUSIONS: We have developed a semantically equivalent translation with cultural adaptation of EORTC QLQ-C30 questionnaire. The assessment of its measurement properties showed that it is quite reliable and a valid measure of the effect of cancer on the quality of life in Moroccan patients.
