The impact of COVID-19 pandemic on breast surgery in Italy: a multi-centric retrospective observational study.

COVID-19 pandemic had an impact on surgical activities. The aim of this multi-centric, retrospective study was to evaluate the impact of the COVID-19 pandemic on breast surgery. The patients who operated during the pre-pandemic year 2019 were compared to those operated in 2020. Fourteen Breast Care Units provided data on breast surgical procedures performed in 2020 and 2019: total number of breast-conserving surgery (BCS), number of 1st level oncoplastic breast surgery (OBS), number of 2nd level OBS; total number of mastectomies, mastectomies without reconstruction, mastectomies with a tissue expander, mastectomies with direct to implant (DTI) reconstruction, mastectomies with immediate flap reconstruction; total number of delayed reconstructions, number of expanders to implant reconstructions, number of delayed flap reconstructions. Overall 20.684 patients were included: 10.850 (52.5%) operated during 2019, and 9.834 (47.5%) during 2020. The overall number of breast oncologic surgical procedures in all centers in 2020 was 8.509, compared to 9.383 in 2019 (- 9%). BCS decreased by 744 cases (- 13%), the overall number of mastectomies decreased by 130 cases (- 3.5%); mastectomy-BCS ratio was 39-61% in 2019, and 42-58% in 2020. Regarding immediate reconstructive procedures mastectomies with DTI reconstruction increased by 166 cases (+ 15%) and mastectomies with immediate expander reconstruction decreased by 297 cases (- 20%). Breast-delayed reconstructive procedures in all centers in 2020 were 142 less than in 2019 (- 10%). The outburst of the COVID-19 pandemic in 2020 determined an implemented number of mastectomies compared to BCS, an implemented number of immediate breast reconstructions, mainly DTI, and a reduction of expander reconstruction.

Immediate breast reconstruction with latissimus dorsi flap for patients with local recurrence of breast cancer.

BACKGROUND: Ipsilateral breast cancer recurrence (IBTR) occurs in about 7% of patients with primary invasive breast tumor. Salvage mastectomy and breast reconstruction are often discussed and latissimus dorsi (LD) flap is frequently proposed. METHODS: We retrospectively investigated 111 consecutive locally relapsing patients who underwent salvage mastectomy and immediate LD reconstruction. All included patients with IBTR previously underwent conserving surgery for BC, and received a postoperative irradiation. Primary endpoints were disease free survival and overall survival. Secondary endpoints were surgical complications and re-interventions. RESULTS: Invasive ductal cancer was the most frequent histotype (60.4%) of breast cancer reappearance. rpT1, rpT2 and rpT3 were observed respectively in 50.5%, 20,7% and 3,6% of the patients. rpTis occurred in 11,7% of cases. Positive axillary nodes were observed in 9,9% of patients at reappearance. Post-operative complication other than seroma occurred in 17,1% of patients, while seroma at the donor site was observed in 61.3% of cases. At 5-year after surgery overall survival was 92% (95% CI: 85%-96%) and disease free survival was 78% (95% CI: 69%-85%). CONCLUSIONS: Immediate latissimus dorsi flap reconstruction in selected patients with isolated breast tumor recurrence, which occurred after breast irradiation, provides an effective treatment with a satisfactory outcome.

Nipple-sparing mastectomy with different approaches: surgical incisions, complications, and cosmetic results. Preliminary results of 100 consecutive patients at a single center.

Nipple- and areola-sparing mastectomy is a novel surgical approach that preserves the nipple-areolar complex. Patients with moderate and/or severe breast ptosis are usually not eligible for this surgical approach. In this study, we aimed to demonstrate the feasibility of nonconventional surgical approaches for nipple-sparing mastectomy. One hundred consecutive patients diagnosed with primary breast cancer (BC) were enrolled in this study. Clinical and pathological data such as body mass index, smoking status, breast ptosis, complications, and aesthetic satisfaction (Breast-Q test) were collected. According to different types of breast ptosis, surgical procedures were classified as (a) hemi-periareolar, (b) round block, (c) vertical pattern, and (d) wise pattern skin incisions. We performed statistical analysis to assess the correlation with complications, degree of ptosis, and breast-Q scores. Among the 117 surgical procedures performed in 100 patients with BC, no significant associations are verified considering clinical and pathological data, complications, pre- and postsurgery satisfactions, and other parameters. Different surgical approaches represent the evolution of "classic" nipple-sparing mastectomy, thus meeting the cosmetic and oncological results. These procedures are safe and also indicated in cases conventionally considered as not eligible for nipple-areola preservation.

Oncological results of oncoplastic breast-conserving surgery: Long term follow-up of a large series at a single institution: A matched-cohort analysis.

PURPOSE: Oncoplastic surgery is a well-established discipline that combines conserving treatment for breast cancer with immediate plastic reconstruction. Although widely practiced, the oncologic outcomes of this combined approach are reported only in small series. The aim of the present paper is to assess the safety of oncoplastic surgery for invasive primary breast cancer. METHODS: We compared 454 consecutive patients who underwent an oncoplastic approach between 2000 and 2008 for primary invasive breast tumors (study group) with twice the number of patients who received conservation alone in the same interval time (control group). Disease free survival and overall survival were estimated using the Kaplan-Meier method. The log-rank test was used to assess differences between groups. RESULTS: The median follow-up was 7.2 years. The overall survival is similar within the two groups, being 91.4% and 91.3% at 10-yr in the study group and in the control group respectively. The disease free survival is slightly lower in the oncoplastic group (69 vs.73.1% at 10-yr). The difference is not statistically significant. DISCUSSION: We have compared a large series of primary breast cancer patients that have undergone oncoplastic surgery (454) with a control group (908) and they were followed for a prolonged period of time. It provides the best available evidence to suggest that oncoplastic surgery is a safe and reliable treatment option for the managing of invasive breast cancer.

Neourethral meatus reconstruction for vulvectomies requiring resection of the distal part of the urethra.

OBJECTIVE: Vulvar cancer is a relatively rare tumour accounting for just 5% of all gynaecological malignancies. Radical excision can sometimes involve the distal one-third to one-half of the urethra leading to postoperative problems with micturition, asymmetries and psychosexual distress. Although this topic has been largely addressed, no specific method for distal urethra reconstruction has been described. The aim of this paper is to assess the safety and reliability of our reconstructive technique. METHODS: We conducted a retrospective study of 47 consecutive patients who underwent neourethral meatus reconstruction with vaginal mucosa flap. The surgical technique is described step-by-step. We reviewed the patients' demographics, operative characteristics, as well as immediate complications and long-term outcomes. RESULTS: Neo-meatal reconstruction was combined to direct vulvar closure in 2 patients, rhomboid flaps in 3 cases, 1 bilateral lotus flap and 36 V-Y fasciocutaneous flaps, 4 rectus abdominis and 1 gracilis flap. Wound dehiscence at the site of the neourethral reconstruction occurred in only 4.3%, partial necrosis of the vaginal mucosa flap in 2.1%. Totally post-operative early complication rate including the whole procedures was 29.8% with a re-operation rate of 4.3%. Long-term outcomes were evaluated in 68.1% patients, including 18.7% of urinary incontinence, no urethral stenosis and 25% of narrowed vaginal introitus. CONCLUSION: Neourethral meatus reconstruction using the vaginal mucosa flap is a simple, safe and reliable technique with a very low early complication rate. We suggest that this flap could be a good option to preserve and restore urinary function in case of distal urethral amputation.

Evaluation of fat grafting safety in patients with intraepithelial neoplasia: a matched-cohort study.

BACKGROUND: Fat grafting is widely carried out in breast cancer patients to improve quality in breast reconstruction. Recently, in vitro and animal studies have questioned the role of adipose tissues in cancer development. DESIGNS: Matched-cohort study. We analysed: (i) 59 intraepithelial neoplasia patients who had undergone lipofilling, with no recurrence between primary surgery and lipofilling. (ii) A control group of 118 matched patients (two controls per lipofilling patient) with the corresponding recurrence-free intervals. Both groups were also matched for main cancer criteria. A local event (LE) was the primary end point, with follow-up starting from the baseline. RESULTS: Median follow-up was 63 and 66 months from surgery, and 38 and 42 from baseline, for the lipofilling and control groups, respectively; the 5-year cumulative incidence of LE was 18% and 3% (P = 0.02). Ki-67 was the significant factor in univariate survival analysis. A subgroup analysis showed that lipofilling increased the risk of LE in women <50 years, with high grade neoplasia, Ki-67 ≥ 14 or who had undergone quadrantectomy. CONCLUSION: Higher risk of LE was observed in intraepithelial neoplasia patients following lipofilling. Although further studies are required to validate our conclusions, patients belonging to this subgroup should be informed of these results and the potential risks.

Locoregional recurrence risk after lipofilling in breast cancer patients.

BACKGROUND: Lipofilling has been indicated for postmastectomy and postlumpectomy breast reconstruction. The clinical literatures underline its technical efficacy but experimental studies raise important questions about the potential detrimental effect of adipocytes on the stimulation of cancer growth and reappearance. DESIGN: We collected 321 consecutive patients operated for a primary breast cancer between 1997 and 2008 who subsequently underwent lipofilling for reconstructive purpose. For each patient, we selected two matched patients with similar characteristics who did not undergo a lipofilling. RESULTS: Eighty-nine percent of the tumors were invasive. Median follow-up was 56 months from the primary surgery and 26 months from the lipofilling. Eight and 19 patients had a local event in the lipofilling and control group, respectively, leading to comparable cumulative incidence curves [P = 0.792; Hazard Ratio(Lipo vs No lipo) = 1.11 (95% confidence interval 0.47-2.64)]. These results were confirmed when patients undergoing quadrantectomy and mastectomy were analyzed separately and when the analysis was limited to invasive tumors. Based on 37 cases, the lipofilling group resulted at higher risk of local events when the analysis was limited to intraepithelial neoplasia. CONCLUSIONS: Lipofilling seems to be a safe procedure in breast cancer patients. Longer follow-up and further experiences from oncological series are urgently required to confirm these findings.

Laparoscopic total fallopian tube removal at the time of bilateral salpingo-oophorectomy in BRCA2 positive women.

About 10% of all serous ovarian cancer has BRCA1 and/or BRCA2 mutations. Recent data showed that following the SEE FIM protocol it is possible to evidence more fimbriae cancers. Due to those studies, fallopian tube cancer in recent years has become the predominant site of cancer in BRCA1 and/or 2 mutation carriers. The pathological study of the fallopian tube is not complete during salpingo-oophorectomy because a small part (intramural site) is situated inside the uterus. In this case report we demonstrate how it is possible to remove the tubes entirely for pathological analysis without hysterectomy by laparoscopic surgery.

Safety of fat grafting in secondary breast reconstruction after cancer.

BACKGROUND: Fat grafting is largely used to correct soft-tissue defects in any region of the human body. This study analysed its safety when the technique is used to correct defects after breast-cancer reconstruction. METHODS: A total of 158 patients who underwent 194 breast fat grafting procedures were analysed. Almost all patients (98%) had a personal history of breast cancer: conservative surgery or mastectomy with breast reconstruction. In all cases, fat grafting was performed according to the Coleman's technique by a single surgeon. RESULTS: Immediate complications included liponecrosis and infection in seven cases (3.6%) that required only daily dressings and oral antibiotics administration. In cases of fat grafting after conservative surgery, only four patients (5.9%) showed minor alterations in the postoperative mammograms, consisting of the appearance of benign images. CONCLUSION: Breast fat grafting can be a good solution to repair defects after breast-cancer treatment and reconstruction, and can reduce the indication for more extensive surgeries such as myocutaneous flaps. Postoperative complication rates are very low and there is little alteration in follow-up mammograms. Two points remain unclear--how much of the fat is absorbed after grafting and the potential risk of local 'dormant' tumour cells being stimulated to induce a local recurrence.

Nipple sparing mastectomy with nipple areola intraoperative radiotherapy: one thousand and one cases of a five years experience at the European institute of oncology of Milan (EIO).

In order to reduce mutilation, nipple-areola complex (NAC) conservation can be proposed for the treatment of breast cancer when mastectomy is indicated. To reduce the risk of retro areolar recurrence, a novel radiosurgical treatment combining subcutaneous mastectomy with intraoperative radiotherapy (ELIOT) is proposed. One thousand and one nipple sparing mastectomies (NSM) were performed from March 2002 to November 2007 at the European institute of oncology (EIO), for invasive carcinoma in 82% of the patients and in situ carcinoma in 18%. Clinical complications, aesthetic results, oncological and psychological results were recorded. A comparison was performed between the 800 patients who received ELIOT and the 201 who underwent delayed one-shot radiotherapy on the days following the operation. The median follow up time was 20 months (range 1-69) for a follow up performed in 83% of the patients. The NAC necrosed totally in 35 cases (3.5%) and partially in 55 (5.5%) and was removed in 50 (5%). Twenty infections (2%) were observed and 43 (4.3%) prostheses removed. The median rate of the patients for global cosmetic result on a scale ranging from 0 (worst) to 10 (excellent) was 8. Evaluation by the surgeon in charge of the follow-up gave a similar result. Only 15% of the patients reported a partial sensitivity of the NAC. Of the fourteen (1.4%) local recurrences, ten occurred close to the tumour site, all far from the NAC corresponding to the field of radiation. No recurrences were observed in the NAC. In a group of patients characterized by a very close free margin under the areola, no local recurrence was observed. Overall, 36 cases of metastases and 4 deaths were observed. No significant outcome difference was observed between the 800 patients receiving intraoperative radiotherapy (ELIOT) and the 201 patients receiving delayed irradiation.

Nipple-sparing mastectomy: risk of nipple-areolar recurrences in a series of 579 cases.

BACKGROUND: When the conservative treatment is not recommended, Nipple Sparing Mastectomy (NSM) is proposed more and more frequently for the surgical treatment of breast cancer. The risk of local recurrence behind the nipple areolar complex (NAC) is the main limiting factor of the NSM procedure. To minimize such risk, we proposed in 2002 a intraoperative radiotherapy of the preserved NAC. PATIENTS AND METHODS: From March 2002 to November 2006, 579 cases (in 570 patients) of NSM were performed for carcinoma. The median follow up time was 19 months (Range: 1-60). The subcutaneous mastectomy was performed through an incision removing a portion of the skin overlying the tumour. An extemporaneous histological examination was performed on the retroareolar glandular tissue. If the histology was positive the patient was not considered eligible. Then an intraoperative radiotherapy with electrons (ELIOT) of 16 Gy in one shot was delivered on the NAC area. An immediate breast reconstruction was done using implants in most cases and in several cases a musculocutaneous flaps, usually in large breast. The number of local recurrences was recorded and the correlation between their occurrence and the clinical and histological criteria were analysed using the Gray test statistical method in a competing framework. RESULTS: In 516 cases the negative retroareolar frozen section biopsy was confirmed by the final histology, while in 63 cases, the final histology showed foci of carcinoma. Seven out of these 63 cases underwent a secondary NAC removal. In the 56 cases which preserved areolas we did not observe any local recurrence after 19 months follow up. The probability of retro areola positive histology increases with the tumour size. and was not related to the nodal status. The rate of local relapses was 0.9% per year. We didn't find any significant difference in the local relapse rate according to different patient's and tumour's features. Most relapses were located close to the tumour bed but never in the NAC area. CONCLUSION: Our study confirms that the local recurrence rate in the NSM completed with local radiotherapy on the NAC is not higher than the usual rate observed in the literature and the preservation of the NAC does not increase the risk. The absence of local recurrence in the region where a portion of glandular tissue has been purposely preserved is a good argument in favour of ELIOT.

Oncological results of immediate breast reconstruction: long term follow-up of a large series at a single institution.

BACKGROUND: Reconstruction of the breast after mastectomy is an integral part of the complete management of breast cancer. However, a delay in the reconstruction is usually proposed after the mastectomy in case of invasive cancer, while there is a general agreement for immediate breast reconstruction in case of in situ tumors. PATIENTS AND METHODS: Among a total of 677 patients having undergone a mastectomy between 1997 and 2001, 518 (76.5%) underwent an immediate breast reconstruction (IBR). All the patients had a Patey mastectomy for invasive cancer (T1-T3). An adjuvant medical treatment was given according to the biological characteristics of the tumor and lymph node status. No patient received any kind of radiotherapy. The median follow up was 70 months (range 13-114). RESULTS: The local recurrence rate was 5.2% for the group of IBR and 9.4% for the mastectomy group without IBR (NoIBR). The regional metastases rate was 1.4 vs. 1.3%. The rate of distant metastases was 13.9 vs. 16.4%. Contra-lateral breast tumor was observed in 1.5 vs. 1.3%. Death rate was 10.4 vs. 16.4%. No statistical difference was observed between the two groups in terme of overall survival (OS) and disease free survival (DFS) (HR(IBR vs. NoIBR): 1.03 and 0.99 for OS and DFS, respectively). CONCLUSION: At our institution we have compared a large series that have undergone IBR (518) with a control group (159) and followed over a prolonged period of time (70 months). This study provides the best available results to suggest that IBR is a safe and reliable treatment option for the managing invasive breast cancer.

Long-term oncological results of breast conservative treatment with oncoplastic surgery.

Oncoplastic surgery combining breast conservative treatment (BCT) and plastic surgery techniques may allow more extensive breast resections and improve aesthetic outcomes, but no long-term oncological results have been published. Long-term oncologic results of 148 consecutive BCT with concomitant bilateral plastic surgery have been analysed and were compared to historical data of BCT trials. Median follow-up was 74 months. Complete excision was obtained in 135 patients (91%); focally involved margins in 8 (5%); and close (<2 mm) margins in 5 (3%). Five patients developed ipsilateral recurrence (3%), 19 (13%) developed distant metastasis and 11 patients died (7.53%). Patients with tumours larger than 2 cm were at greater risk of local recurrences and distant metastasis. Long-term oncologic results of BCT with oncoplastic surgery are comparable with the results of BCT randomized trials.

Breast conservative treatment in association with implant augmentation and intraoperative radiotherapy.

After conservative treatment for small breast cancer the use of breast implants is controversial due to the negative effects of external conventional radiotherapy on soft tissues and the risk of capsular contracture. The literature reports several cases of unsuccessful breast augmentation due to implant displacement, a high percentage of capsular contracture and postoperative complications. We report the case of a 47-year-old woman with a small tumour between the inner quadrants of the left breast. She underwent quadrantectomy and sentinel node biopsy and intraoperative radiotherapy (IORT) of the target zone. Simultaneously, she received a bilateral augmentation mammaplasty. One year later we observed no evidence of local recurrence, no local fibrosis and radiodistrophy. Cosmetic results are excellent and the patient is very satisfied. The surgical technique and the possible advantage of such a procedure are also discussed.

Evaluation of skin perfusion after nipple-sparing mastectomy by indocyanine green dye. Preliminary results.

The aim of the study was to investigate the blood supply of the normal nipple areola complex (NAC) and the spared areola complex after a nipple-sparing mastectomy using the analysis of the fluorescence from the indocianine green dye (ICG) injection. Between December 2002 and July 2003 we performed the ICG analysis in 10 cases of healthy breasts and in 9 patients after a nipple-sparing mastectomy and one patient after subcutaneous mastectomy. In all cases, the resulting fluorescence was measured in three different zones: nipple, areola, surrounding mammary skin. Three parameters of the fluorescence curve (slope, maximum intensity, time to achieve a maximum level) were recorded. On the healthy breast, the nipple showed a very high perfusion as compared to the other zones. On the contrary, after the mastectomy the fluorescent pattern was completely altered, being the perfusion of the nipple very low. In conclusion, these preliminary results confirm the applicability and the importance of the ICG technique for evaluating the perfusion of the healthy and spared areola after surgery. Because of the small number of patients further studies are needed.

When mastectomy becomes inevitable: the nipple-sparing approach.

The preservation of the nipple areola complex (NAC) could improve the quality of life in cases of mastectomy. A novel radiosurgical treatment combining subcutaneous mastectomy with intraoperative radiotherapy is proposed. Three hundred nipple-sparing mastectomies (NSM) were performed. Invasive (58%) and in situ (42%) carcinomas were included. Clinical complications, aesthetic results, oncological and psychological results were recorded. The NAC necrosed totally in 10 cases and partially in 29 and it was removed in 12. Nine infections (3%) were observed and 10 prostheses removed. Good results were rated by 82.3% of the patients and by 84.8% of the surgeons. In 7.5% a radiodystrophy was observed. The sensitivity of the NAC recovered partially in 48%. Two local recurrences occurred outside the radiated field. Overall, we observed three metastases and no deaths. Sixty-eight of the patients were satisfied with their reconstructed breast and 85.5% were satisfied having preserved the NAC.

Immediate breast reconstruction and high-dose chemotherapy.

BACKGROUND: Immediate breast reconstruction (IBR) is considered as a safe procedure nowadays, and it can be proposed in the majority of patients requiring a mastectomy. In fact, recent studies have demonstrated that immediate breast reconstruction is not detrimental also to patients with locally advanced breast cancers. However, IBR should be reevaluated in case of locally advanced breast cancer requiring high-dose chemotherapy (HDCT). The aim of this study is to evaluate both the risk of chemotherapy delay due to surgical complications and the risk of late surgical complications related to the association with HDCT. We considered 3 series of 23, 67, and 15 patients requiring a mastectomy at the European Institute of Oncology in Milan. After mastectomy, these groups respectively received an IBR and HDCT, an IBR and conventional chemotherapy, and only HDCT with no IBR. METHODS: Files of 105 patients who were admitted to our department from October 1999 to January 2002 were reviewed. Twenty-three patients underwent a mastectomy, followed by IBR and HDCT; 67 underwent a mastectomy plus IBR plus conventional CT; and, finally, 15 underwent a mastectomy alone followed by HDCT. The reconstructive techniques performed were 72 permanent prosthesis and 18 temporary expanders. We excluded all patients with IBR by flap (latissimus dorsi or pedicled rectus abdominis) to improve the homogeneity of the sample. RESULTS: All patients who underwent IBR started high-dose chemotherapy without any delay; the time elapsed between surgery and HDCT is not significantly different for patients with and without IBR (54 versus 60 days, P = 0.13). The early complication rate (before CT) was 2.9% (2 patients with infection). The late complication rate (after CT) was higher for the group that underwent IBR followed by HDCT (39% versus 20%). CONCLUSION: We did not observe any delay for the administration of high-dose chemotherapy after mastectomy with IBR surgery. The complication rate before HDCT is similar to the complication rates published in the literature. On the contrary, we observed a higher rate of infections (13% versus 0%, P = 0,014) after HDCT than after conventional CT, which can be related to the association with high-dose chemotherapy, inducing a decrease of the immune defenses. These results seems to demonstrate that the association of IBR with HDCT is not detrimental to patients from the oncological point of view, but the impact of HDCT on the reconstruction is more negative. Further studies are needed to verify if this risk exists, although lower, in the association with conventional CT. However, a careful evaluation of the risk of infections should be considered preoperatively, and perioperative contaminations should be carefully prevented.

Interrupted micro-mattress sutures solve vessel-size discrepancy.

Although technical refinements have improved microvascular techniques, the problem of vessel-size discrepancy between donor and recipient vessels is still unsolved and can decrease the success rate of free tissue transfer. In fact, if vessels with incongruent diameters are not adequately anastomosed, the risk of free flap failure is increased. In this paper, the authors present a new type of microvascular anastomosis to overcome the problem of vessel-size discrepancy. Interrupted mattress sutures are placed in end-to-end anastomosis narrowing the wider diameter and compensating for the diameter incongruency. The surgical technique and main clinical applications of the interrupted micro-mattress sutures are described in detail. Indications and advantages are discussed.

Recycling spare tissues: splitting a bipedicled TRAM flap for reconstruction of the contralateral breast.

A new method of bipedicled transverse rectus abdominis myocutaneous flap splitting to reconstruct the contralateral breast 1 year after the first breast reconstruction is presented. This technique can be useful in cases of large salvage mastectomy for asynchronous breast cancers allowing a bilateral thoracic closure.
