Abstract
Background In India, breast cancer patients' post-treatment follow-up practices are not known. We did this survey to understand how the breast cancer patients are followed-up and tried to explore the challenges associated with it.
Methods We conducted a survey-based study among Indian oncologists. Seven questions were framed pertaining to follow-up practices. Answers were provided in the form of multiple options. Google forms platform was used. Survey was circulated through social media apps and through mail. We sought suggestions and opinions to address the challenges from participants.
Results A total of 158 medical oncologists responded to this survey. 10% were not aware that only history and clinical examination are the scientific recommendations for follow-up. Ninety percent of the medical oncologists felt clinical breast examination as an uncomfortable practice for patients and physicians and 39% ordered a chest X-ray and an ultrasound abdomen. Annual mammogram was ordered by 83%, and blood investigations were recommended by 14% routinely. The majority (49.6%) felt that the absence of a female attendant, physician and patient factors were responsible for nonadherence to clinical breast examination. The DEXA scan was recommended by 84 (53%) medical oncologists regularly for patients on aromatase inhibitors, while 23 (14%) did not recommend it.
Conclusion There is a disparity between scientific recommendations and real-world follow-up practices. A large number of medical oncologists relied on chest X-ray and ultrasound abdomen. There is an unmet need to address this issue.

Introduction
Breast cancer is the most common cancer in India. In 2018, 162468 new cases of breast cancer were diagnosed, and the outcomes of these patients are improving.[1] Careful follow-up after end of therapy is important for timely detection of recurrences or complications of therapy. Summary of recommendations regarding the same by various scientific bodies are depicted in [Table 1]. The follow-up recommendations of breast cancer patients after completion of treatment are dependent on good history taking and clinical breast examination (CBE), every 3 to 4 months for initial 2 years and then every 6 months from third to fifth year and annually thereafter.[2] Annual mammography is recommended for all breast cancer patients.[2] [3] [4] Bone health monitoring by dual-energy X-ray absorptiometry (DEXA) scan is recommended, and investigations like chest X-ray (CXR), computed tomography (CT) scan of chest and abdomen, ultrasound of abdomen (US-A) or positron emission tomography (PET)-CT scan are not recommended unless there are clinical symptoms and/or signs. The current evidence for follow-up and screening practices is not considered as strong evidence for recommendations.[5] The randomized studies conducted in the 80s and 90s addressing the role of intensive investigations in breast cancer follow-up failed to demonstrate an overall survival benefit.[6] [7] [8] Advances in metastatic breast cancer treatment have occurred after the conduct of these studies. The survival outcomes in metastatic breast cancer have increased phenomenally over 1990 to 2009.[9] Detecting relapse early by investigations like CXR and US-A might lead to improved survival and/or quality of life. Many physicians and institutional practices routinely advocate for CXR, US-A, and CA15–3 as a part of follow-up.[10] [11] [12] There is a wide disparity between recommendations and adherence to them.

Methods
We conducted a survey-based study among Indian medical oncologists who are treating breast cancer patients. Survey form was made pertaining for follow-up practices after completion of treatment of breast cancer patients in curative setting ([Table 2]). Questions on history and physical examination, CBE, issues related to CBE, annual mammography, CXR and US-A, complete blood count (CBC), liver function tests (LFTs), renal function tests (RFTs), and bone health monitoring by DEXA scan were included. Questions were framed to understand the challenges in following-up of patients. Answers were provided in the form of multiple options. This survey was conducted from January 3 till July 31, 2020. The survey was circulated through social media apps and through mails. Google forms platform was used. As survey was circulated through social media apps, responses from only medical oncologists were taken for analysis.

Results
A total of 158 medical oncologists participated out of 344. Majority (90%) of medical oncologists were aware of the universal recommendation of history and physical examination in follow-up of breast cancer patients postchemotherapy.
CBC, LFTs, and RFTs were ordered by 14% during every visit and 68% ordered these investigations only as per symptoms ([Fig. 1]).
A total of 155 medical oncologists responded on factors relating to CBE as an uncomfortable practice ([Fig. 2]). 83% (n = 130) ordered the annual mammography for their patients ([Fig. 3]). Only 7% felt that the CBE can be easily practiced in their workplace without any limitations.
Absence of female attendants in the clinic was the only factor of concern for 12.2% (n = 19) of medical oncologists. Physician's reluctance, fear of litigation by female patient, and time constraints were the factors reported by 2%, 2%, and 1%, respectively. Patient factor of conservativeness and unwillingness was mentioned by 32 (20%) of the medical oncologists. Majority (49.6%) felt that the absence of a female attendant, physician and patient factors are all responsible for less practice of CBE.
CXR and US-A were advised by 39% of medical oncologists ([Fig. 4]).
The DEXA scan was recommended by 84 (53%) medical oncologists regularly for patients on aromatase inhibitors, while 23 (14%) did not recommend the DEXA scan. Only three asked for DEXA scan as per symptoms. Others did not answer this question.

Discussion
In a systematic literature review by de Guzman et al, the median adherence to follow-up recommendations of breast cancer patients in eight European countries was 74% (range 0–84%).[10] Similarly, in the survey conducted by Foster et al on guideline adherence in American medical oncologists, 82% ordered annual mammogram, and 22% asked for CA15–3 and chest imaging every 6 months for 5 years by 16%.[11] In our survey, 83% ordered the annual mammogram, and CXR and US-A were ordered by 39% of medical oncologists, which is very high in comparison to American medical oncologists.
In India, sociocultural issues introduce limitations in conducting CBE. Only 7% (n = 12) felt CBE as a comfortable practice. This fact was not reported before. The predominant patient factors were conservativeness and unwillingness addressed by 20% of medical oncologists; however, this finding is limited by absence of patient's view on this. Future studies should address this issue. The medical history taking and clinical examination is considered by many to be a declining art.[13] The backbone of a follow-up is clinical examination; an inadequate clinical examination may miss important findings, leading to delay in recognition of relapse. In many parts of the world, the ability to perform a proper CBE might be limited by sociocultural factors and economics (e.g., availability of adequate staff, examination rooms with privacy).
Physician factors can be overcome by increasing awareness for benefits of these essential parts of patient care, which are taught during residency.[14] One of the reasons emphasized for nonadherence to CBE was absence of a female attendant (12%). Such barriers can be overcome by providing the female attendants during breast cancer clinic hours, although it may not be possible in every clinic.
Ten percent of medical oncologists were not aware or did not follow the existing guidelines of follow-up of breast cancer patients, which is not reported before. The practice of DEXA scan recommendation also deviated from the scientific recommendations.[15] Only 53% percent have advised for regular bone health monitoring.
Although the existing guidelines are based on older studies, cost is saved if guidelines are adhered, and unnecessary investigations will not be prescribed.[11] These investigations might also lead to unnecessary invasive procedures and fear of uncertainty and increase stress for the patients. However, there is a missing link of newer studies between recommendations based on older studies and real-world practices and their challenges.
Phenomenal progress has been made in treatment of breast cancer in the last four decades, and this was achieved because of understanding of the disease and treatment of breast cancer as three subsets (hormone positive, Her2neu positive and triple negative).[16] The guidelines of follow-up are based on old data and not on robust scientific data.[5] [10] There is a need to readdress this issue of follow-up of breast cancer patients, as they are not universally practiced, and newer therapies are available for three subtypes of breast cancer. It will be prudent to start follow-up study, according to subtypes prospectively, as new treatments might lead to change in outcomes of these patients. Indian oncology societies should come forward and formulate India specific guidelines.
#
Strength of the Study
For the first time, such a survey was conducted that brought out the issues inherent to follow-up practices of breast cancer patients after completion of chemotherapy. As the data on follow-up practice is very old, this survey brings out the importance in this important field of oncology practice, which has wide implications. Such topics are never discussed in pharma-driven medical oncology conferences.
#
Limitations of the Study
The denominator of respondents might be different, as survey was circulated through multiple social media apps. However, number of respondents was large. Only medical oncologists were surveyed. Surgical and radiation oncologists were not included in this study. Survey lacked the questions of demographics of respondents like age, sex, and region of practice. Pre- and postmenopausal patients' category was not considered for use of DEXA scan. The practice domain of medical oncologists is not taken into consideration like academic versus nonacademic or private versus government hospitals.
#
Conclusion
This survey-based study highlighted the challenges for follow-up of breast cancer patients in India. Scientific recommendations are not universally followed. CXR and US-A are recommended by 39% of the medical oncologists, and 90% felt CBE as an uncomfortable practice for patients and physicians. Annual mammogram is ordered by 83% and blood investigations were recommended by 14% routinely.
