100 patients will be assigned into a control group.

Expanded Mckissock surgery: (1) According to patient's preoperative imaging results and subjective expectations of their own breast morphology, the incision design and breast surface marking will be performed under the standing position. (2) After general anesthesia, the upper limbs will be abducted, and the upper body will be tilted by 15°-20° to dermatize the labeled skin around and below the areola. (3) The medial and lateral flaps will be dissociated to remove the total gland with nipple and areola preserved. (4) The cutting-edge of nipple-areola complex will be sent for cancer screening. The axillary lymph node biopsy or cleaning will be performed along the outer edge of the pectoralis major muscle. (5) The vertical subcutaneous pedicle flaps will be W-folded, and the flaps on both sides will be pulled to the vertical pedicle to reshape the breast. During this process, the breast and armpit drainage tubes will be indwelled.

Expanded Mckissock surgery

The patients will be placed in the supine position. After intravenous anesthesia, the tumor boundary will be marked and the breast will be removed. The vertical subcutaneous pedicle flaps will be W-folded, and the flaps on both sides will be pulled to the vertical pedicle to reshape the breast. During this process, the breast and armpit drainage tubes will be indwelled.

Modified radical mastectomy

Extensive intraductal carcinoma of the breast refers to a type of breast cancer in which ≥ 25% of ductal carcinoma in situ is present in invasive tumors and there is a scattered distribution of ductal carcinoma in situ (DCIS) in or around the invasive carcinoma. Compared with DCIS negative for extensive intraductal component, DCIS positive for extensive intraductal component is not sensitive to radiotherapy. Mckissock surgery was applied in breast-conserving surgery for breast cancer in 2016. Jianyi Li and the team members (Shengjing Hospital of China Medical University, Shenyang, China) applied this technique in breast-conserving surgery with preservation of the nipple-areola complex. This surgical technique is suitable for low-grade malignant tumors and has better prognosis than radical mastectomy. The purpose of this study is to investigate postoperative disease-free survival and quality of life after modified radical mastectomy versus expanded Mckissock surgery for extensive intraductal carcinoma of the breast. Results from this study will indicate the efficacy of expanded Mckissock surgery in the treatment of extensive intraducatal carcinoma of the breast.

Extensive intraductal carcinoma of the breast refers to a type of breast cancer in which ≥ 25% of ductal carcinoma in situ is present in invasive tumors and there is a scattered distribution of ductal carcinoma in situ (DCIS) in or around the invasive carcinoma. Studies have shown that patients with DCIS positive for extensive intraductal component have more residual tumors than patients with DCIS negative for extensive intraductal component. There are still many subclinical tumors in the residual mammary gland after removal of the main invasive tumor foci. This provides the condition for tumor recurrence after breast-conserving surgery, and the risk of tumor recurrence in DCIS positive for extensive intraductal component is 2.52 times that in DCIS negative for extensive intraductal component. Compared with DCIS negative for extensive intraductal component, DCIS positive for extensive intraductal component is not sensitive to radiotherapy.

Mckissock surgery is originated from a breast reduction surgery developed by American doctors in 1970, which can remove glands to the maximum extent. This technique was applied to breast-conserving surgery in 2016, which initiated the application of this operation in malignant tumors. Jianyi Li and the team members (Shengjing Hospital of China Medical University, Shenyang, China) first applied expanded Mckissock surgery in breast-conserving surgery with the nipple-areola complex preserved. This surgical technique is suitable for low-grade malignant tumors. This surgical technique has been performed in 30 patients and results showed that the expanded Mckissock surgery has better prognosis than radical mastectomy. Therefore, this prospective cohort study will compare the postoperative disease-free survival and quality of life between modified radical mastectomy and expanded Mckissock surgery.

DFS and QOL After Modified Radical Mastectomy vs. Expanded Mckissock Surgery for EIC of the Breast

Postoperative Disease-free Survival and Quality of Life After Modified Radical Mastectomy Versus Expanded Mckissock Surgery for Extensive Intraductal Carcinoma of the Breast: a Prospective Cohort Study Protocol

Disease-free survival refers to the time from surgical resection of breast cancer to clinically confirmed local recurrence, distant metastasis, second primary tumor diagnosis, or patient death.

The QLQ-BR23 scale will evaluate the quality of life. The QLQ-BR23 scale consists of 23 items with a full score of 92. Higher score indicates poor quality of life.

The symmetry of reconstructed breast will be evaluated using Harris score. The Harris score was described by Harris et al. (Int J Radiat Oncol Biol Phys 1979; 5: 257- 261.) It will be divided into four levels: excellent, good, fair, and poor.

Patient randomizes to metal or plastic insertion prior to Whipple procedure

Plastic and metalic stent inserion

Randomized study comparing the effect of plastic stents to that of expandable metal stents as pre-operative drainage of the bile ducts prior to Whipple operation.

Patients suffering from a locally invasive tumour process in the Periampullary area usually seek medical attention because of jaundice. Not only do patients suffering from jaundice show significant symptoms of exhaustion and purities, but they are also at higher risk for developing post-operative complications. Experimentally, the liver exhibits a reduced capacity for tolerating ischemia in the presence of jaundice. Several different etiologic factors suggest cause complication such as presence of toxic substances as bilirubin and bile salts, impaired nutritional status, effects of endotoxins, bacterial translocation, modulation of the inflammatory cascade with cytokine release, reduction of cellular immunity and nutritional. These complications primarily consist of septic complications (cholangitis, abscesses, and leakage), haemorrhage, impaired wound healing and renal disorders. Summarily, these issues have motivated pre-operative bile flow drainage by way of stent. Traditionally, pre-operative bile flow drainage has been achieved by insertion of a EP because these are considered easy to remove and cause less tissue reaction in the bile ducts. However, multiple studies have found the disadvantage with the EP is that it provides poorer bile drainage than the SEMS.

In palliative situations, metal stents have been associated with fewer side-effects in the form of fever relapse of jaundice, etc. These effects are likely due to better bile flow through the stent. It remains unclear if metal stents can provide similar advantages in the curative situation.
