    Abstract: 子宮肌瘤乃是婦科常見的一種疾病,其發生率極為普遍,在35歲以前的婦女,約有1/5長有子宮肌瘤,子宮肌瘤常合併有月經異常等疾患,嚴重者,會導致貧血,流產等症狀,雖然良性子宮肌瘤發生惡性變化之比率極少,然而,從以前之學者研究中,可見肌瘤的染色體核型呈現有多樣的變化,常有一些有趣的結果發現,本實驗乃針對此點,做一個詳細的探討。
      於台南市郭綜合醫院的婦科手術裡,隨意地挑選33例良性子宮肌瘤的患者,進行組織培養和染色體分析,所有的肌瘤,術後之病理切片檢查都是良性肌瘤,而染色體分析採用1985 I S C N 的範本。
      實驗結果,顯示 33例肌瘤病人中,19位呈現正常的女性核型46,XX(占63.3%),11位有不正常的核型(占36.7%),例無法培養出細胞來,乃在11例不正常的染色體核型中,有9例為染色體構造上異常,其中又以病例9, 31和 32表現出複合性異常。
      本實驗裡,就肌瘤的大小來講,利用統計學加以分析,結果顯示,較大的肌瘤,較易發生染色體的異常(P value<0.05),然而,以年齡來說,卻沒有顯著的差異(P value>0.05)。
      本實驗裡,病例8和26,可見到del(6) (q 24),病例15,觀察到del (7) (q 31.2),病例20,31和32人分別發現r(4) 和r(1),病例32,尚可見到t(12;14) (q 15; q 24)病例9,可見到t(13;8)(p 11; q 11), der(6) t(6;) (q 21;),另外在病例1,10和28,共有三例單倍體22,以上之發現與以前的文獻報導有吻合之處。
      從以上的結果,顯示在一些較常見的染色體斷裂點,是否存在有主控子宮肌瘤的基因位置,從以前的文獻裡也常有學者發表類似的文章,相信這些訊息對以後的分子遺傳學者必有些許的助益。
      Cytogenetic analysis of 33 uterine leiomyomas showed abnormal karyotypes in 11 cases. In 9 of 11 aberrant tumors, normal cells were also observed. Structural changes were most frequent, resulting in modal chromosome numbers in the diploid range.
      Our data confirmed preferential breakpoint clusters at 1 p34.2, 3 q13.3, 6 q21, 6 q24, 7q 31.2, 11 p12, 12 q15, 14 q24. We also found monosomy 22, ring chromosome 1 and 4 in uterine leiomyomas.
      Statistical analysis of possible relationships between tumor karyotypes ( abnormal versus normal ) and clinico-pathological data, as well as age of the patients, menopausal status and tumor size showed specific significance between myoma node size and abnor-mal karyotypes. (P value<0.05)
      We concluded that while many uterine myomas have normal karyotypes, clonal chromosome abnormalities are presented in 36.7 % of these tumors. The study of chromosome rearrangements in benign tumors might be helpful in defining chromosome regions associated with abnormal proliferation of cells.
