Background: Breast cancer is the most commonly diagnosed malignancy in women worldwide. Women with dense breast tend to have 15-25% lifetime risk of breast cancer due to decrease of mammographic sensitivity. Automated breast ultrasound (ABUS) is a new promising tool for detection of breast lesions masked by dense glandular tissue at mammography. Results: The sensitivity of digital mammography in detecting breast lesions was 60.7%, specificity 91.6%, PPV 85%, NPV 75%, and accuracy 78%. The sensitivity of ABUS in detecting breast lesions was 92.86%, specificity 77.78%, PPV 76.47%, NPV 93.33%, and accuracy 84.38%. The sensitivity of handheld ultrasound (HHUS) in detecting breast lesions was 89.29%, specificity 88.89%, PPV 86.21%, NPV 91.43%, and accuracy 89.06%. Conclusion: The sensitivity of ABUS in detecting breast lesions was much higher than mammography in dense breast while the digital mammography (DM) had higher specificity. So, implementation of both DM and ABUS to get benefit of DM specificity as well as ABUS sensitivity were highly recommended.

In India cancer patients come at a very advanced stage with many of them being crossed the stage of resection. A wide range of non invasive techniques like toludine blue staining, methylene blue staining, Narrow band imaging have been developed for the early detection of malignant and premalignant lesions in the mucosa including oral cavity and gastrointestinal tract. However it is difficult for the clinicians to decide which diagnostic tool is most appropriate and useful for screening, resulting in failure to pick up the lesions at an early stage. Various online journals have been reviewed and no journal was found to support this point. This study here by describes Toludine blue and narrow-band imaging (NBI), diagnostic tools already proven independently as a useful screening method in many fields, and demonstrate its usefulness in the early detection of premalignant and malignant lesions of the oral cavity, as reported by previous studies in the otolaryngologic literature and compare both screening tools which has not been done till now. This study was done in a tertiary referral centre in middle India from March 2018 to August 2019 in order to evaluate the role of different screening tools (NBI and Toludine blue).44 patients with suspicious oral cavity lesions (premalignant and malignant) who had given consent for both NBI and toludine blue screening techniques were selected from the suspected (premalignant and malignant lesions) who had visited the OPD during the study period. Patients with proven malignancy were excluded from the study. A detailed history of the patient taken and standard Ear, nose, throat, oral cavity and neck examination of patient carried out. After subjecting the patients to screening tools like NBI and toludine blue, the efficacy of these techniques in helping us to take a representative biopsy was evaluated. In present study the sensitivity (to correctly identify all patients with disease), specificity (to correctly reject healthy patients without disease) of older technique toludine blue in detecting premalignant lesion was 66.6%, 87.8% while for NBI was 66.6%, 95%. For malignant lesion sensitivity and specificity of toludine blue was 94.3%, 100%, while the same for NBI was 100%, 88.8% respectively. Both NBI and toludine blue staining can be adopted for screening and the accurate detection of biopsy site and in the follow up of premalignant lesions to look for malignant transformation. Time tested is Toludine blue which is cheap and easily available. But being a better tool and having an upper hand in evaluating the lesions, NBI should be made available in all the secondary and tertiary care centres as a screening method.
