RESUMEN
Multiple myeloma (MM) significantly increases the risk of venous thromboembolism (VTE) within 6 months of treatment initiation. The IMPEDE VTE score is a VTE risk prediction model which is recently incorporated into the National Comprehensive Cancer Network (NCCN) guidelines, but it lacks validation among Asians, including Chinese MM patients. We performed a retrospective chart review of 405 Chinese with newly diagnosed MM who started therapy at Beijing Jishuitan Hospital between April 2013 to October 2022. The 6-month cumulative incidence of VTE was 3.8 % (95 % CI:1.6-7.6), 8.6 % (95 % CI: 5.3-21.9) and 40.5 % (95 % CI: 24.9-55.7) in the low-, intermediate- and high-risk groups (P < 0.001), respectively. The C-statistic of the IMPEDE VTE scores for predicting VTE within 6 months of treatment initiation was 0.74 (95 % CI: 0.65-0.83). Of note, in this single-center cohort study, we propose that the anticoagulant LMWH may be more effective than the antiplatelet aspirin in potentially preventing VTE in newly diagnosed MM patients. Our findings suggest that the IMPEDE VTE score is a valid evidence-based risk stratification tool in Chinese patients with newly diagnosed MM.

Purpose: Vitamin D deficiency is frequent in patients with multiple myeloma (MM), however, its prognostic relevance in MM was rather inconclusive. We first investigated the association of vitamin D deficiency with abnormal bone and lipid metabolism in newly diagnosed multiple myeloma (NDMM), and next assessed the impact of serum ratio of vitamin D to carboxy-terminal telopeptide of type I collagen (ß-CTX) on progression-free survival (PFS) and overall free survival (OS) in patients with NDMM. Methods: The data of 431 consecutive patients with NDMM at Beijing Jishuitan Hospital from September 2013 to December 2022 were collected and retrospectively reviewed through our electronic medical record system. The measurement of 25-hydroxyvitamin D in the blood is an indicator of an individual's overall vitamin D status. Results: The serum levels of vitamin D were negatively correlated with ß-CTX in NDMM patients. Of note, positive correlation between vitamin D and cholesterol levels in the serum was found in this study. The cohort (n = 431) was divided into two groups based on the serum ratio of vitamin D to ß-CTX. Compared to the group with a higher vitamin D to ß-CTX ratio, the group with a lower vitamin D to ß-CTX ratio (n = 257, 60%) exhibited hypocholesterolemia, inferior PFS and OS, along with increased cases of ISS stage-III and R-ISS stage-III, a higher number of plasma cells in the bone marrow, and elevated serum calcium levels. Consistent with this, multivariate analysis confirmed that the vitamin D to ß-CTX ratio was an independent unfavorable indicator for survival in NDMM patients. Conclusion: Our data demonstrated the ratio of vitamin D to ß-CTX in the serum is a unique biomarker for NDMM patients to identify the high-risk cases with poor prognosis, which is superior to vitamin D itself for predicting PFS and OS in NDMM. Also, it is worth mentioning that our data on the connection between vitamin D deficiency and hypocholesterolemia might help clarify novel mechanistic aspects of myeloma development.

The indications for percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP) are painful vertebral compression fractures. Our study is to assess the risk-benefit ratio of PKP/PVP surgery in the patients with newly diagnosed multiple myeloma (NDMM) without receiving antimyeloma therapy. The clinical data of 426 consecutive patients with NDMM admitted to our center from February 2012 to April 2022 were retrospectively analyzed. The baseline data, postoperative pain relief, the proportion of recurrent vertebral fractures, and survival time were compared between the PKP/PVP surgical group and the nonsurgical group in the NDMM patients. Of the 426 patients with NDMM, 206 patients had vertebral fractures (206/426, 48.4%). Of these, 32 (32/206, 15.5%) underwent PKP/PVP surgery for misdiagnosis of simple osteoporosis prior to diagnosis of MM (surgical group), and the other 174 (174/206, 84.5%) did not undergo surgical treatment prior to definitive diagnosis of MM (non-surgical group). The median age of patients in the surgical and nonsurgical groups was 66 and 62 years, respectively (p = 0.01). The proportion of patients with advanced ISS and RISS stages was higher in the surgical group (ISS stage II + III 96.9% vs. 71.8%, p = 0.03; RISS stage III 96.9% vs. 71%, p = 0.01). Postoperatively, 10 patients (31.3%) never experienced pain relief and 20 patients (62.5%) experienced short-term pain relief with a median duration of relief of 2.6 months (0.2-24.1 months). Postoperative fractures of vertebrae other than the surgical site occurred in 24 patients (75%) in the surgical group, with a median time of 4.4 months postoperatively (0.4-86.8 months). Vertebral fractures other than the fracture site at the first visit occurred in 5 patients (2.9%) in the nonoperative group at the time of diagnosis of MM, with a median time of 11.9 months after the first visit (3.5-12.6 months). The incidence of secondary fractures was significantly higher in the surgical group than in the nonsurgical group (75% vs. 2.9%, p = 0.001). The time interval between the first visit and definitive diagnosis of MM was longer in the surgical group than in the nonsurgical group (6.1 months vs. 1.6 months, p = 0.01). At a median follow-up of 32 months (0.3-123 months), median overall survival (OS) was significantly shorter in the surgical group than in the nonsurgical group (48.2 months vs. 66 months, p = 0.04). Application of PKP/PVP surgery for pain relief in NDMM patients without antimyeloma therapy has a limited effect and a high risk of new vertebral fractures after surgery. Therefore, patients with NDMM may need to have their disease controlled with antimyeloma therapy prior to any consideration for PKP/PVP surgery.

BACKGROUND: The incidence of breast cancer among women of reproductive age is increasing, as well as the desire for children at late childbearing age. Identifying factors that may be associated with fetal malformation and maternal and fetal prognosis has gained importance. We describe a 32-year-old woman with breast cancer who gave birth to a son with congenital bilateral cryptorchidism after treatment, with a literature review performed. CASE SUMMARY: A 32-year-old woman with breast cancer who had been treated by surgery and radiotherapy experienced recurrence and underwent a second surgery, adjuvant chemotherapy, and targeted therapy. Her tumor cells were negative for estrogen receptor (ER) α, progesterone receptor (PR), and p53; positive for ERß, human epidermal growth factor receptor-2 (HER2), epidermal growth factor receptor (EGFR), and Ki67. She had pathogenic BRCA gene mutations. She became pregnant within 2 years and delivered a boy with congenital bilateral cryptorchidism. The boy underwent bilateral orchidopexy. As of this writing, the woman and her son are both healthy. CONCLUSION: HER2 overexpression, positivity for EGFR, Ki67, and ER, and PR negativity are associated with a poor prognosis in breast cancer. While no link has been established statistically between treatment for breast cancer and cryptorchidism in a subsequent pregnancy, this case suggests the possibility that ERß and gene mutations may be contributing factors.
